About 4.00 Update

If I have 3.00-Stable Kit up and running, can I just overwrite the files on my 3DS card with this update and continue using rxTools, or should I repeat the setting up process again with this new files?

No, you just need to overwrite the files with the new ones.

In case the SD card isn't touching the 3DS contacts correctly, try re-inserting the SD card a few times.
If that doesn't fix it then it's definitely your SD card (corrupted maybe). Backup the SD contents, format the card (you won't lost emunand, it's on another partition), restore sd card contents, and try again.

OMG @samiam144 If you format the entire card, you'll lose the emuNAND partition as well :/ just deleting the visible partition and then formatting the unallocated space as FAT32 on Primary would have worked.

Hello everyone and thank A LOT for a very handy and detailed tutorial.
As I am relatively new to the whole "downgrade 3DS - custome firmware - .3ds & cia file" and all that jazz, I beg beforehand for your forgiveness if my questions seem n00bish or have been answered before. To the point now:
As I understand - correct me if I'm worng - my line of thinking is the following:
1. In order to play .cia files, I need custom firmware installed on my O3DS (I have a recently downgraded 9.2.0-20E one).
2. In order to access my installed custom firmware (RXD10.3.0 blah blah) I need to use the internet every time I boot my 3DS, to switch from the sysNAND to the emuNAND.

Using the internet every time to switch to the emuNAND seems like a problem, especially in cases where I'm on vacation and I don't have wifi anywhere near.
Is there a way to switch to my cfw and install/play cia games without having to use the internet every time?

Again, thanks for your patience and for any possible replies.

If you follow the tutorial until the end (install menuhax, using HxD to edit the menuhax ropbinpayload .bin file and stuff), you won't need internet connection at all to access CFW/emuNAND

What you need and what you probably want are 2 different things (and believe me, I know what you want).
What you want is: An Emunand partition on your sd card and a cfw to launch into it

No. There are other ways on launching the cfw. The browser is just one of them. Look at the op section "cold boot".

NINJAED

But yes, emuNAND is safer (although you can safely use sysNAND too if you block nintendo's server ^^ )

Stupid question:

have hacked my 3DS using this Tutorial.

Everything works so far so good

How to install themes.
I have installed CHMM2
have downloaded a few themes

I Start CHMM2 in emunand mode, and i can see my downloaded themes.
I select any Theme. Press A, an i can see that CHMM2 do something.
I restart my Console but nothin happens..

any ideas why this dnot work?

Regards, kind Sir.
And via what software can I do that?

Geofonos · Jan 15, 2016

WOW! So many answers in so little time! This has got to be the best support I got from a forum^^. Kudos!
Thank you all for your answers, I will try following the guide down to the very last bit of it and get back to you if I stumble uppon any problems.
Also, I would like to ask for the devs permission in order to translate the guide given in the first post in Greek, for my fellow gamers and to support the scene. If there are any problems with that, please inform me. Of course, I will ask for permissions from everyone involved and give credits accordingly.
Big thanks once again!

Does anyone else have this? I installed rxtools on an o3ds xl on 9.2 and made an emunand and updated to 10.3. Everything works perfectly but sometimes when I go into system settings there is no 'RX' in front of the 10.3 (even though it is definitely in emunand).

I use MiniTool Partition Wizard Free

Did you setup menuhax in emunand? That will cause problems. Go into emunand -> hbl -> menuhax manager and delete the extdata

Never had this problem. Did you unlink your nands?

Mefisteso · Jan 15, 2016

1. I've followed the guide with success (with some improvements as it's a bit outdated) using RXtools 2.6 as I heard 3.0 isn't too stable, however now I'm missing Menuhax boot option, so what would be the simplest way to do upgrade 2.6->3.0?

2. Also when I've been using Emunand9 (through menuhax, guide should be updated for this option), it of course formatted my SD Card, however 3DS couldn't read content anymore(on PC it was readable), so I made a backup of a Emunand9 folder (which contained just Emunand9.log file), then I formatted 3DS on my own using FAT32 system file, then I put all the files (previous full backup+emunand9 folder) and everything worked flawlessly.
I can boot into Sys/EmuNand. They look different indeed, however I wonder why does it work?

3. Does it mean that emunand9 tool is there just for formatting SD card(+NAND backup ofc) and RXtools actually creates Emunand partition?

4. Where can I find my emunand partition?

General requirements:

The web browser app OR a way to use Ninjhax OR a Gateway flashcard

A DS flashcard only if your system is on 4.X or 6.X and you have no web browser

Firmware version requirements:
Old 3DS/XL
USA & EUR & JAP: Firmware 4.X-9.2
Each method's level of difficulty from Easiest to hardest:
Gateway > *hax (Homebrew Launcher) > FBI Injection > Downgrading + Palantine/PBT CFW

2DS
USA & EUR & JAP: Firmware 6.X-9.2
Each method's level of difficulty from Easiest to hardest:
*hax (Homebrew Launcher) > Gateway > FBI Injection
(*hax and Gateway are switched because Gateway is known to sometimes have issues with the Multirom menu loading on a 2DS)

N3DS/XL (not covered in this guide, read below)
USA & EUR & JAP: Firmware 8.X-9.2
Each method's level of difficulty from Easiest to hardest:

Git commit: a08cfdd

Important information:

If you already have an EmuNAND, following this guide will overwrite your current EmuNAND. If you don't know what you're doing, ask!

If there is a part A and B of a certain section, do NOT do both. You only need to do the one that is relevant to you. For example, Section 4a and 4b do the same thing, but use different methods (the web browser or the Homebrew Launcher, respectively).

Section 1 - Setting up the SD card!
Thanks to @AidanLumina !

1. See AidanLumina's tweet here and download the 4.00 Update.

2. Now click the link to his Tumblr and download the 3DS CFW Kit.

3. If you're using Windows, unblock the downloaded zips.

4. Extract them both into separate folders.

5. Open the CFW Kit 3.00 folder. You will find an "ExtractThisHereIf_old3DS_or_2DS.zip" file; extract its content into the folder it is in. (Select to overwrite if asked.) After it is finished extracting, delete "ExtractThisHereIf_new3DS.zip" and "ExtractThisHereIf_old3DS_or_2DS.zip"

6. Go into the CFW Update folder. You will find an "ExtractThisHereIf_old3DS_or_2DS.zip" file; extract its content into the folder it is in. (Select to overwrite if asked.) After it is finished extracting, delete "ExtractThisHereIf_new3DS.zip" and "ExtractThisHereIf_old3DS_or_2DS.zip"

7. Move the contents of the CFW Update folder to the CFW Kit 3.00 folder and merge or overwrite any files.

5. Now copy everything in the CFW Kit 3.00 folder onto your 3DS/2DS SD card (except for the PC_Apps folder) and select to overwrite or merge if asked.

Now all needed files are on the SD card. Continue to Section 2.

Notice for users that already have Menuhax installed: This CFW Kit changes the Menuhax picture to a black screen, and replaces the Menuhax button config.
The button config is as follows:

Menuhax loads if no buttons are held at boot.

Menuhax does not load if any button is held at boot.

Section 1 - Optional: Updating rxTools!
Only do this step if you have problems with the rxTools build from Section 0

Download the recommended RxTools build for this guide here
TEMPORARY MIRROR LINK: Here

If you choose to use rxTools 2.6 or 2.5.2, skip this section.

Download Python version 2.7

Direct Windows installer link

If you are using Windows, right-click the rxtools.rar and open Properties. If at the bottom, it says the file is blocked, check "Unblock" and Apply. This should take care of any problems you have with the following steps.

Mac users: If you're having problems running rxtools (black screens, Installation Suite errors, etc.) try extracting the rxtools zip using a reputable .zip extractor or a Windows PC (or virtualbox).

Backup and delete any "rxtools" folder that you may have on your SD card before doing the following steps!

1. Put the "rxtools" folder on your SD card root.

2. Run cdn_firm.py in the "Tools" folder. It will generate a firm folder in the same folder that cdn_firm.py is in. The firm folder must go into the rxTools folder like so: SD:/rxtools/firm

3. If your 3DS is below 7.x firmware: Get "slot0x25KeyX.bin" (Hint: google it, download link should be in the description of a certain youtube video ) (MD5: 817FD1BFFBA60F79CF8CDF19CAF28923). Put this file on your SD card root.

4. For Homebrew Launcher users, you also need to get the "rxtools" folder (found inside the ninjhax folder from the rxtools zip) and put it alongside your other homebrew apps.
It should look like this:
SD:\3DS\rxTools\rxtools.3dsx
SD:\3DS\rxTools\rxtools.smdh

Section 2 - Making your NAND Backup!

To launch EmuNAND9 using the web browser:
Open your 3DS web Browser and go to is.gd/loade9 to launch EmuNAND9.

To launch EmuNAND9 using the Homebrew Launcher:
Boot the HBL and select EmuNAND9.

To launch EmuNAND9 using Menuhax + CTRBootManager:
Turn on your 3DS and hold SELECT when the bottom screen turns white, and keep holding until you are in the CTRBootManager menu. Select EmuNAND9.

Once in EmuNAND9, navigate to EmuNAND Manager Options and then Dump SysNAND to NAND.bin. This will create a NAND backup of your 3DS.

Wait for the backup to finish, then turn off your 3DS. Find NAND.bin on your SD card and transfer it to your PC for safe-keeping (seriously). You don't need to keep it on your SD card.

Continue to Section 3.

Section 3 - Launch rxTools for the first time!

To launch from the internet browser: boot up your 3DS
Open your 3DS internet Browser and go to https://dukesrg.github.io/?rxTools/sys/code.bin (you should bookmark this. To do so, turn off your WiFi, then attempt to connect to the URL. It will fail; now you can open the browser menu and bookmark it.)
If it fails or gives you an error, click the wrench icon and clear cookies and history before trying again. If that doesn't work, clear all save data as well (should be at the very bottom of the browser settings).

To launch from the Homebrew Launcher, just select RxTools from the HBL.

To launch from Menuhax + CTRBootManager, don't press anything while your 3DS is turning on.

Hold L when the bottom screen glitches to get into the menu if it is sending you back to the homemenu!!!

It should show you an Installation Data Suite. Press A when it completes; it should then tell you that EmuNAND is not found; this is normal, we didn't create EmuNAND yet.

So now that we know that it works, turn off your 3DS and continue to Section 4.
If you have Homebrew Launcher access, follow Section 4b.
Else, follow Section 4a.

Section 4a - Installing a CIA Installer
Only for users without a Gateway card or Homebrew Launcher access

Adapted from this thread (thanks @d0k3 and co.!)
Please visit that thread if you have any issues with this section.

In the web browser, go to is.gd/loadd9wip to launch Decrypt9WIP.

Navigate to SysNAND File Options and then Dump Health & Safety. Let the process finish.

Turn off your 3DS.

Go back to your 3DSCFWKIT_V3.00-STABLE folder and open the PC_Apps folder.

Open the UniversalInjectGenerator folder.

Insert your 3DS SD into your PC.

Find the hs.app file on your SD and place it in the Input folder that is inside the Inject Generator folder. There will be a BigBlueMenu.cia already in there.

Run go.bat. If there are no issues, you will find that there are two inject-ready .app files in the Input folder.

To finally inject BigBlueMenu into SysNAND, rename the BigBlueMenu-with-banner.app file to hs.app and place it on your SD, overwriting the one that is already there.

Launch Decrypt9WIP again, and navigate to SysNAND File Options.

Choose health&safety inject to inject the hs.app. Don't worry, it's not as dangerous as you may think.

Now, launch the rxTools menu (hold L during launch), and boot RXMODE SysNAND.

You will be booted to what appears to be regular SysNAND.

Navigate to the H&S app and it should now be the BigBlueMenu app (Title Manager)!

Launch BigBlueMenu.

Go to the SDMC tab. Basically, this is your SD card it is looking at.

Navigate to the CIAs folder and install DevMenu_2x.cia and old3DS.AGB_FIRM.Patch.cia (if this one doesn't let you install, you can use the DevMenu app to install it)

You just installed your first CIAs!

Continue to Section 5 now.

Download FBI.cia

1. Boot up your 3DS and launch rxTools. Hold L when the bottom screen glitches to get into the menu.

2. Press dpad RIGHT to go to Advanced Options -> Press A -> Install FBI -> Press A -> choose EMUNAND, then select "check TMD version".

3. Take note of the console region and the TMD version, and turn off your 3DS.

4. Open the rxtools download and open the "Tools/fbi_injection/[region]/[version]" folder and copy the "fbi_inject.app" and "fbi_inject.tmd" files to the SD card root dir.

5. Put the FBI.cia from the FBI download onto your sd card

6. Boot up your 3DS and launch rxTools. Hold L when the bottom screen glitches to get into the menu.

7. Press dpad RIGHT to go to Advanced Options -> Press A -> Install FBI -> Press A -> choose EMUNAND, then select "Install FBI". When it's done, it will ask what you want to do with the source. Select "keep" if you want to install FBI to sysnand later.

8. Now, return to the rxtools main menu and select RXMODE -> EMUNAND and launch the Health & Safety Information app, it should boot FBI instead

9. Select FBI.cia and press A to install it.

In your SD card, there should be a Nintendo 3DS folder. Open it, and open the folder inside that (has a long name of random numbers and letters); that is your Sysnand's ID folder.

If there are two or more ID folders, then do the following steps for both folders. One folder is for your Sysnand and the other is for your Emunand; if there is another similar folder, it probably belongs to another 3DS that you inserted your SD card into. Ignore the "private" folder if there is one.

There should be another folder within, so open that too. You should now see an "extdata" folder. If you don't see a "dbs" folder as well, download this zip folder and put the "dbs" folder beside the extdata folder.

*Again, if the dbs folder already exists, and you have a title.db and import.db file inside, do not replace them!

Should look similar to this:

Now, boot the 3DS/2DS and go into Settings —> Data Management —> Software. It’ll ask to reset or repair your software management information or sd card, so allow it to do so. Do this in Sysnand and Emunand!

10. You should now have a new FBI app on your home menu, use that to install your CIAs!

Section 4b - Installing a CIA Installer
For users that have Homebrew Launcher access

If you are not using Menuhax+CTRBootManager to access the HBL:

Boot the HBL, and select Pasta CFW Loader or Mini-Pasta (Try Mini-Pasta first)

Once you boot into Pasta (which looks like your regular 3DS HOME menu), run the HBL again and this time select the FBI homebrew application.

Next, navigate to the CIAs folder and install Devmenu_2x.cia

Switch Destination to NAND and install old3DS.AGB_FIRM.Patch.cia.

This installs Devmenu_2x (for installing CIAs from the HOME menu) and the AGB_FIRM Patch (for playing GBA games) to your sysnand.

If you are using Menuhax+CTRBootManager to access the HBL:

Turn on your 3DS and hold SELECT when the bottom screen turns white, and keep holding until the CTRBootManager menu comes up.

Select MiniPasta.

After you press A, hold SELECT again when the bottom screen turns white, and keep holding until the CTRBootManager menu comes up again.

This time, select Homebrew Launcher.

Once in the HBL, launch FBI.

Navigate to the CIAs folder and install Devmenu_2x.cia

Switch Destination to NAND and install old3DS.AGB_FIRM.Patch.cia.

Done, simply hold the power button to turn off your 3DS.

Continue to Section 5 now.

Section 5 - Creating EmuNAND!

We will now create EmuNAND!

Backup your SD card now.

Launch EmuNAND9 again.

To launch EmuNAND9 using the web browser:
Open your 3DS web Browser and go to is.gd/loade9 to launch EmuNAND9.

To launch EmuNAND9 using the Homebrew Launcher:
Boot the HBL and select EmuNAND9.

Once in EmuNAND9, navigate to Complete EmuNAND Setup. Ignore the starter.bin warning and follow the instructions. Wait for the EmuNAND creation process to finish.

Once that's done, you can put all your SD card contents back on your card.
You don't need to put NAND.bin back on your sd card unless you want to downgrade to 4.X (not recommended).

Section 6 - Unlinking your NANDS
Using the recommended method of formatting SysNAND

We will now unlink your NANDs. But first, some information.

The benefits of unlinking your NANDs:

You will not have to unwrap all your games whenever you enter emuNAND.

This doesn't happen to everyone, but if it does, unlinking your NANDs will stop this from happening.

In the past, some users have reported their sysNAND updating even though they were sure they updated emuNAND. These same people happened to have linked NANDs. We don't know if it is related but it is safer unlink your NANDs if you fear this may happen to you.

You can go into sysNAND's Data Management (found in the System Settings app) safely.

Doing this while your NANDs are linked will result in your emuNAND games, saves, themes, etc. being deleted.

The disadvantages of unlinking your NANDs:

If you want to play GBA games in emuNAND, you will have to install the GBA game in both NANDs, taking up double the space.

If your NANDs are linked, you only need to install GBA games in sysNAND once.

Your sysNAND will be formatted.

Don't worry, everything that was on your sysNAND is in emuNAND instead.

If you don't like this, you can always use EmuNAND9 tool to restore your NAND.bin, thus recovering all your sysNAND stuff.

Now finally, how to unlink your NANDs:

Download TinyFormat

Place the .cia in your SD card (CIAs folder if you want to be organized)

Boot into rxmode SysNAND

Don't know how? Hold L when booting rxTools to get into the menu. From there you can select which rxmode you would like to access. Note: 2.5.2 users have to hold R instead.

Once you're in the HOME menu, launch BigBlueMenu, Devmenu_2x, or FBI

Install the TinyFormat.cia

Press HOME and choose to launch TinyFormat

Follow the instructions to complete the formatting of SysNAND, and thus unlinking your NANDs

Turn off your 3DS after the process is finished

Reboot your 3DS and complete the Initial 3DS Setup.

NANDs are now unlinked!

How unlinked NANDs may look like on your SD card:

On your SD card, open the "Nintendo 3DS" folder.
The folder with the smallest size and random numbers/letters belongs to your sysNAND. This is your sysNAND's ID folder.

Go back to the 3DSCFWKIT_V3.00-STABLE folder and copy the dbs folder to this directory:
SysnandIDFolder/RandomNumbersAndLettersFolder/

If there is a "dbs" folder already, you are in the wrong ID folder!

Don't worry, it is normal that the two files are 0KB!

Lastly, boot up your 3DS/2DS and go into Settings —> Data Management —> Software. It’ll ask to reset or repair your software management information or sd card, so allow it to do so.

Section 7 - Updating EmuNAND!

If you have an update nag on sysnand, follow these short steps to delete the update from your system first, reducing any risk of updating sysnand to be EXTREMELY unlikely. Do not do step 4 obviously, click "no"!

To update your emunand, only do so through the System Settings app.
Do NOT update if it asks you if you're "ready to start system update" or whatever it says whenever you boot your 3DS. Also, NEVER update through the eShop. It will update your sysNAND instead.

If you need Emunand tool (for backing up and restoring your emuNAND if you ever need to), then you can find it here.

How to properly update emuNAND on an O3DS or 2DS:

Boot into Emunand, and launch System Settings.

Make sure it says RX-E or RX3D in front of the version number to be sure that you are in emuNAND

Do NOT exit System Settings at this point or you will be kicked back to sysNAND!

Press Other Settings

Scroll to the right until you see System Update

Press System Update and accept

When it is done, your 3DS will reboot into sysNAND

When you launch rxTools and boot into emuNAND, you will see that it is now updated to the latest version

Let's recap.

This is what we've done up to this point:

We set up rxTools for accessing via the browser or the Homebrew Launcher - this is not the only way to access rxTools, and it is actually the most inefficient way to do it. Read the Menuhax (recommended) or MSET section to learn more!

We made a NAND backup - this is important in case you ever brick your 3DS.

We injected/installed BigBlueMenu to SysNAND and used it to install Devmenu_2x and the patched AGB_FIRM - this is beneficial because:

You can use it to install GBA and DSi games

You will always have a CIA installer when you update your EmuNAND.

We created EmuNAND.

EmuNAND provides a layer of protection, which helps prevent our SysNAND from being updated or bricked.

We unlinked our NANDs in order to avoid certain issues.

We have updated EmuNAND to the latest version - this allows the highest game compatibility, and eShop access.

----------------You are now ready to install CIAs! Read further to learn about RxTools' other features and capabilities!----------------

How to install Games, Updates, Patches, DLC, Homebrew, etc. using BigBlueMenu / Title Manager / BBM / Devmenu

Download any .cia file. Don't ask where to get them. There is a certain iso site for 3DS games that you can find on Google.

Place the .cia file(s) on your SD card. I recommend placing them in a CIA folder to avoid clutter.

Open RXMODE EmuNAND or SysNAND (depending on which nand you would like to access the .cia from).

Launch BigBlueMenu / Title Manager, or any other CIA Installer that you have installed.

Go to the SDMC tab.

Go to the location of the .cia file(s)

Highlight the .cia and press A.

Press A once more to confirm the installation.

Wait for it to finish.

If you want to delete the .cia file after installation (since it isn't needed anymore once installed), highlight the .cia and press X, then A to confirm.

Press HOME and you should get a notification that you have a new app.

This only happens if it's a new game, app, or homebrew that you installed. There is no notification if you just installed DLC, a game update, or a System App.

Unwrap the gift and enjoy!

DSi/GBA/NES/etc. support

The patched AGB_FIRM is no longer needed (although in this guide, we already had you install it just in case

DSi games can be ran through sysNand, and reportedly emuNand as well. Install to sysNand to play them in sysNand; install to emuNand AND sysNand if you want to play them in emuNand. DSi cias must be installed to NAND destination (if using FBI).

GBA games can be ran through emunand, or sysnand. They still have to be installed to both emunand and sysnand if your nands are unlinked! GBA games should be installed to SD (if using FBI).
Personally I just install them to Sysnand and play them from there.

Have a DS flashcard?

If you have a DS flashcard that was able to be used on a 3DS at some point before Nintendo blocked it, you may be able to use it again! Note: The following method will not work for old DS flashcards that were blocked since the release of the original 3DS.

Note: You need to use a CIA installer other than BigBlueMenu. Use FBI or Devmenu_2x
Please read the Understanding FBI at the very bottom of this guide before using FBI.
If you don't want to read that, use Devmenu_2x, it is simpler to use.

On your 3DS:

Launch RxMode Sysnand and open FBI or Devmenu_2x.

If using FBI: Press L to change Destination to NAND.

Navigate to the CIAs folder.

Select DSFlashcardWhitelistPatch.cia and press A to install it.

If using FBI: Choose to overwrite the title when it prompts you.

Once done, exit the CIA installer.

You should now able to use your DS flashcard on your 3DS.
Things to note:

If your DS flashcard still doesn't work, then it will probably never work on your 3DS.

You should be able to use your DS flashcard in any mode (Sysnand, RxMode, Devmode/Pasta Mode), but exiting the card will bring you back to regular sysnand.

Running a DS flashcard will remove your MSET exploit if you have one (see the next section).

You can use a DS flashcard to easily install the MSET exploit (see the MSET section).

Launching rxTools at Boot - Menuhax!

These steps will setup Menuhax, which we will configure to allow rxTools to boot the moment you turn on your 3DS/2DS! IMO this is the best way to launch rxTools.

Note: You must be on 9.0 - 9.2 firmware. This means your sysnand has to be on or between 9.0 to 9.2 system version. To update to 9.0 or 9.2, scroll down to the section How to Update your 3DS/2DS to 9.0 or 9.2 and follow the instructions, then come back here.

Second note: This will only work with rxTools 3.0 nightly (from September onwards I think). No one has found a way for it to work with rxTools 2.6 and under as far as I know. The rxTools build included in Section 1 works with this.

Set a random theme on your 3DS, then change it back to the default theme.

Launch rxmode SysNAND (Hold L when booting rxTools to access it)

Open BigBlueMenu (or any other CIA installer)

If you already have access to the Homebrew Launcher, skip to step 8!!

Install hblauncher_loader.cia (it's in the CIAs folder)

Exit to the HOME menu; there will be a new gift. It is the Homebrew Launcher cia.

Launch the Homebrew Launcher via the Homebrew Launcher cia you just installed in SysNAND.

In the Homebrew Launcher, run the menuhax_manager installer and install menuhax.

After all that, test if menuhax boots you into the homebrew menu at cold boot. Just turn off your 3DS and turn it back on, and don't press any buttons.

On your SD card, look for the file which name starts with "ropbinpayload". Open it with HxD (included in the PC_Apps folder) or Notepad++. Maybe plain old Notepad will work too.

Press CTRL+F and search for boot.3dsx. There will be two results.

Change both to auto.3dsx and save the file.

When you turn on your 3DS, you should see the bottom screen flash multiple colors, followed by the rxTools splash screen.
The Menuhax button config is as follows:

Menuhax loads if no buttons are held at boot.

Menuhax does not load if any button is held at boot.

Additionally:

If you hold L after the bottom screen turns white, you will boot into the rxTools menu.

If you hold SELECT after the bottom screen turns white, you will boot into the CTRBootManager menu.

Launching rxTools through the System Settings app - MSET!

These steps will downgrade your System Settings in your sysNand to the 4.x or 6.x version, which is where we will install the exploit. It is the second best entrypoint to booting rxTools, in my opinion.

Note: You need to use a CIA installer other than BigBlueMenu. Use FBI or Devmenu_2x
Please read the section Understanding FBI at the very bottom of this guide before using FBI.
If you don't want to read that, use Devmenu_2x, it is simpler to use.

All users:
Want to launch rxTools via MSET so that you don't need to connect to the internet? Select your system version:

4.X

Use one of the following methods:

EASIEST METHOD: If you have a DS flashcard that works on your 3DS, open the MSET folder in the rxtools download and put the .nds file (rxinstaller.nds) on your DS flashcard's SD card. Now run it with your DS flashcard and select "rxtools 4.x".

To install MSET with FBI, you need to have FBI 1.4.14 or higher on your sysnand. Simply launch rxmode sysnand, launch FBI, and press SELECT. Now, select "rxtools3.x 4.x". MSET should now be installed.

To install MSET with the internet browser, simply put the rxinstaller.bin (from the MSET folder) on your SD card root. Then launch the browser and go to http://dukesrg.github.io/?rxinstaller.bin or http://dukesrg.no-ip.org/3ds/cakes/?rxinstaller.bin . It should freeze and crash, and send you back to the home menu. MSET should now be set up.

To launch rxTools via MSET, just turn on your 3ds, go to System Settings-> Other Settings-> Profile-> Nintendo DS Profile, and rxTools should boot.

5.X

If you don't have a DS flashcard: grab the rxinstaller.bin for rxTools from the "mset" folder and put it in your sd card root.

Go HERE (click the "CIA Format DLC's, Themes & Updates" link. Name of the thread is "[MEGA] [CIA/BIN] MSET 4.X & 6.X backups, Browser backups, Update packs (All Regions)")

Download one of the following cias according to your region:

MSET-USA-4.0 0004001000021000
MSET-EUR-4.0 0004001000022000
MSET-JPN-4.0 0004001000020000

Place the .cia anywhere in your sd card.

Launch RXMODE SysNAND (Hold L when rxTools is booting to get into the menu first)

Launch Devmenu_2x or FBI

Install the .cia you downloaded above and then exit to the HOME menu.

EASY METHOD: If you have a DS flashcard that works on your 3DS, open the MSET folder in the rxtools download and put the .nds file (rxinstaller.nds) on your DS flashcard's SD card. Now run it with your DS flashcard and select "rxtools 4.X DG". Then skip to step 11!

Note: the "DG" beside the system version number means "downgraded".

Open the 3DS browser, and enter this URL: http://dukesrg.github.io/?rxinstaller.bin or http://dukesrg.no-ip.org/3ds/cakes/?rxinstaller.bin

Wait for a bit (it should crash and send you back to the home menu). If it doesn't crash after a minute, press HOME and it should crash.

If the next step (8) doesn't work, try clearing your cache and history before entering one of the above links.

Now you can launch rxtools by going to System Settings-> Other Settings-> Profile-> Nintendo DS Profile

6.X

If you don't have a DS flashcard: grab the rxinstaller.bin for rxTools from the "mset" folder and put it on your sd card root.

EASY METHOD: If you have a DS flashcard that works on your 3DS, open the MSET folder in the rxtools download and put the .nds file (rxinstaller.nds) on your DS flashcard's SD card. Now run it with your DS flashcard and select the 6.X MSET option. Then skip to step 4.

Note: the "DG" beside the system version number means "downgraded". So if you are on 9.x using the 6.x mset, you would use "6.x DG". If you are on 6.x system version, you would use simply "6.x".

If you have FBI installed in sysnand, you can run it, press SELECT, and choose "rxtools3x 6.x" to install the exploit. Then you can skip to step 4.

If you used a DS flashcard in step 1, then skip to step 4! Open the 3DS browser, and go to one of these URLs: http://dukesrg.github.io/?rxinstaller.bin or http://dukesrg.no-ip.org/3ds/cakes/?rxinstaller.bin

Wait for a bit (it should crash and send you back to the home menu). If it doesn't crash after a minute, press HOME and it should crash.

If the next step (4) doesn't work, try clearing your cache and history before entering one of the above links.

Now you can launch rxtools by going to System Settings-> Other Settings-> Profile-> Nintendo DS Profile

7.X - 9.2

If you don't have a DS flashcard: grab the rxinstaller.bin for rxTools from the "mset" folder and put it on your sd card root.

Go HERE (click the "CIA Format DLC's, Themes & Updates" link. Name of the thread is "[MEGA] [CIA/BIN] MSET 4.X & 6.X backups, Browser backups, Update packs (All Regions)")

Download one of the following cias according to your region:
6.X MSET (2DS users must choose one of these or you may brick your 2DS!):
MSET-USA-6.0 0004001000021000
MSET-EUR-6.0 0004001000022000
MSET-JPN-6.0 0004001000020000

4.X MSET:
MSET-USA-4.0 0004001000021000
MSET-EUR-4.0 0004001000022000
MSET-JPN-4.0 0004001000020000

Place the .cia anywhere in your sd card.

Launch RXMODE SysNAND (Hold L when rxTools is booting to get into the menu first)

Launch Devmenu_2x or FBI

Install the .cia you downloaded above and then exit to the HOME menu.

EASY METHOD: If you have a DS flashcard that works on your 3DS, open the MSET folder in the rxtools download and put the .nds file (rxinstaller.nds) on your DS flashcard's SD card. Now run it with your DS flashcard and select "rxtools 4.X DG". Then skip to step 11!

Note: the "DG" beside the system version number means "downgraded".

Open the 3DS browser, and enter this URL: http://dukesrg.github.io/?rxinstaller.bin or http://dukesrg.no-ip.org/3ds/cakes/?rxinstaller.bin

Wait for a bit (it should crash and send you back to the home menu). If it doesn't crash after a minute, press HOME and it should crash.

If the next step (8) doesn't work, try clearing your cache and history before entering one of the above links.

Now you can launch rxtools by going to System Settings-> Other Settings-> Profile-> Nintendo DS Profile

How to Update to a Newer rxTools Version

Download the recommended RxTools build for this guide here
Download Python version 2.7 if you don't have it

Direct Windows installer link

If you are using Windows, right-click the rxtools.rar and open Properties. If at the bottom, it says the file is blocked, check "Unblock" and Apply. This should take care of any problems you have with the following steps.

Backup and delete any "rxtools" folder that you may have on your SD card before doing the following steps!

Place:
1. the "rxtools" folder on the SD card root.
2. the "firm" folder inside of the "rxtools" folder. How to get it:

Run cdn_firm.py in the "Tools" folder. It will generate a firm folder in the same folder that cdn_firm.py is in. The firm folder must go into the rxTools folder like so: SD:/rxtools/firm

For ninjhax users, you also need to replace the rxtools.3dsx and rxtools.smdh found inside the ninjhax folder in the rxtools download zip.

How to Update your 3DS/2DS to 9.0 or 9.2

If you want to boot rxTools as soon as you turn on your 3DS, then you need to set-up Menuhax; and to use Menuhax, you need to be on 9.0 - 9.2 firmware.
Warning: This can brick your 3DS if done incorrectly! Be sure that you follow the instructions carefully!

Requirements:

BigBlueMenu installed in sysnand (Section 4 if you don't have Gateway or Ninjhax) OR any other cia installer on Sysnand.

A rxTools 3.0 nightly (preferably the one linked in Section 1)

Also works on rxTools 2.5.2 (for those that can't launch 3.0)

Let's get started.

See AidanLumina's tweet here and click Files for downgrade/manual update.

Download one of the O3DS 9.2 packs

Once downloaded, open the archive and find the "updates" folder; place it on your SD card. There should be many cia files in that folder.

Example: SD:/updates/0004013000008003.cia

Download Sysupdater

Open the archive and put sysUpdater.cia on your SD card

Insert your SD card in your 3DS

Hold L while launching rxTools to get into the rxTools menu. If using rxTools 2.5.2, hold R instead.

Press DPAD RIGHT until you highlight ADVANCED OPTIONS, then press A. Skip this step if using rxTools 2.5.2

Go down to DEVMODE or PASTA MODE and press A

After a few seconds, you should now be in sysnand; firmware spoofing is disabled but cias can still be launched in this mode.

Launch you CIA installer

Install sysUpdater.cia (Destination: SD if using FBI)

Once installed, press HOME to see sysUpdater wrapped as a gift; unwrap it.

Launch sysUpdater

sysUpdater will ask you if you are sure you want to go ahead with the update; choose to accept it.

It will also tell you that you shouldn't be in Gateway mode, or have firmware spoofing. Do not worry about this, DEVMODE / PASTA MODE has no firmware spoofing, so sysUpdater will work as intended. Just be absolutely sure you are in DEVMODE / PASTA MODE (line 13), not RXMODE SYSNAND!

Wait for sysUpdater to finish. When it is done, your 3DS will reboot into 9.0 or 9.2 firmware! You can now follow the steps to use Menuhax if you'd like.

Click HERE

Click the CIA Format DLC's, Themes & Updates [Archive] result

Click View Full Version : CIA Format DLC's, Themes & Updates at the top of the page

Find the thread titled [MEGA] [CIA/BIN] MSET 4.X & 6.X backups, Browser backups, Update packs (All Regions)

Scroll down to the section titled Updates

Download either the 9.2 modified update pack for your region, or a 9.0 or 9.2 Full Update Pack for you region

How to move Games, Saves, Themes, and Emunand to a new SD card

Get Emunand Tool

Insert your old SD card in your PC

Open Emunand Tool and select "Extract EmuNAND"

Save it somewhere on your PC (as "emunand.bin" if you want)

Backup all your SD card files to your PC

Eject your old SD card

Put Gateway's launcher.dat on your new SD card

Format emunand on your new SD card via the gateway menu

Turn off your 3DS

Insert your new SD card in your PC

Open Emunand Tool and select "Inject NAND to emuNAND"

Select the emunand.bin you made in step 3 & 4

Close Emunand Tool when done

Put backup of SD card files (from step 5) on your new SD card

Done, emunand and files (saves, games, etc.) have been transferred to your new SD card!

Understanding FBI

Unlike other cia installers, FBI allows the user to install to either Nand or SD. 3DS games, game updates, DLC, GBA games, and homebrew, are meant to install to SD. System titles (such as the Internet Browser, or MSET), and DSi games install to Nand. To better understand Nand and SD destination, take a look at these infographics, courtesy of @pakrett and @Hashtastrophe respectively:

-----------------------------------------------------

F.A.Q

If you get the "022-2634" when trying to access the eShop on the latest EmuNAND, try this (thanks to @Nestar):

1. Backup your emuNAND.
2. Backup all emuNAND files (ticket.db etc.) with rxTools.
3. Backup the content of your SD card.
4. Format emuNAND.
5. Recover your SD card content and boot rxTools in emuNAND.
6. Update to 10.3.0-28X and boot into emuNAND again.
7. Go to system settings and to NNID at the top; follow instructions.
8. Boot emuNAND and start the eShop; simply restart the 3DS if it keeps looping after the password input.
9. Once in the eShop, close it and shut down.
10. Recover your whole SD card once more. *
11. Inject emuNAND backup.
12. Inject all emuNAND file backups.
13. Start the eShop in emuNAND and it should refresh your software.
14. And now you should have emuNAND eShop access without any loss ofStreetPass/Save/Friend/etc. data.

Updated for: rxTools 3.0 nightly
Date: 12-05-15_08-48(December 5, 2015 @ 8:48UTC)
Git commit: a08cfdd

Important information:

If you already have an EmuNAND, following this guide will overwrite your current EmuNAND. If you don't know what you're doing, ask!

If there is a part A and B of a certain section, do NOT do both. You only need to do the one that is relevant to you. For example, Section 4a and 4b do the same thing, but use different methods (the web browser or the Homebrew Launcher, respectively).

Section 1 - Setting up the SD card!
Thanks to @AidanLumina !

1. See AidanLumina's tweet here and download the 4.00 Update.

2. Now click the link to his Tumblr and download the 3DS CFW Kit.

3. If you're using Windows, unblock the downloaded zips.

4. Extract them both into separate folders.

5. Open the CFW Kit 3.00 folder. You will find an "ExtractThisHereIf_old3DS_or_2DS.zip" file; extract its content into the folder it is in. (Select to overwrite if asked.) After it is finished extracting, delete "ExtractThisHereIf_new3DS.zip" and "ExtractThisHereIf_old3DS_or_2DS.zip"

6. Go into the CFW Update folder. You will find an "ExtractThisHereIf_old3DS_or_2DS.zip" file; extract its content into the folder it is in. (Select to overwrite if asked.) After it is finished extracting, delete "ExtractThisHereIf_new3DS.zip" and "ExtractThisHereIf_old3DS_or_2DS.zip"

7. Move the contents of the CFW Update folder to the CFW Kit 3.00 folder and merge or overwrite any files.

5. Now copy everything in the CFW Kit 3.00 folder onto your 3DS/2DS SD card (except for the PC_Apps folder) and select to overwrite or merge if asked.

Now all needed files are on the SD card. Continue to Section 2.

Notice for users that already have Menuhax installed: This CFW Kit changes the Menuhax picture to a black screen, and replaces the Menuhax button config.
The button config is as follows:

Menuhax loads if no buttons are held at boot.

Menuhax does not load if any button is held at boot.

Section 1 - Optional: Updating rxTools!
Only do this step if you have problems with the rxTools build from Section 0

Download the recommended RxTools build for this guide here
TEMPORARY MIRROR LINK: Here

If you choose to use rxTools 2.6 or 2.5.2, skip this section.

Download Python version 2.7

Direct Windows installer link

If you are using Windows, right-click the rxtools.rar and open Properties. If at the bottom, it says the file is blocked, check "Unblock" and Apply. This should take care of any problems you have with the following steps.

Mac users: If you're having problems running rxtools (black screens, Installation Suite errors, etc.) try extracting the rxtools zip using a reputable .zip extractor or a Windows PC (or virtualbox).

Backup and delete any "rxtools" folder that you may have on your SD card before doing the following steps!

1. Put the "rxtools" folder on your SD card root.

2. Run cdn_firm.py in the "Tools" folder. It will generate a firm folder in the same folder that cdn_firm.py is in. The firm folder must go into the rxTools folder like so: SD:/rxtools/firm

3. If your 3DS is below 7.x firmware: Get "slot0x25KeyX.bin" (Hint: google it, download link should be in the description of a certain youtube video ) (MD5: 817FD1BFFBA60F79CF8CDF19CAF28923). Put this file on your SD card root.

4. For Homebrew Launcher users, you also need to get the "rxtools" folder (found inside the ninjhax folder from the rxtools zip) and put it alongside your other homebrew apps.
It should look like this:
SD:\3DS\rxTools\rxtools.3dsx
SD:\3DS\rxTools\rxtools.smdh

Section 2 - Making your NAND Backup!

To launch EmuNAND9 using the web browser:
Open your 3DS web Browser and go to is.gd/loade9 to launch EmuNAND9.

To launch EmuNAND9 using the Homebrew Launcher:
Boot the HBL and select EmuNAND9.

To launch EmuNAND9 using Menuhax + CTRBootManager:
Turn on your 3DS and hold SELECT when the bottom screen turns white, and keep holding until you are in the CTRBootManager menu. Select EmuNAND9.

Once in EmuNAND9, navigate to EmuNAND Manager Options and then Dump SysNAND to NAND.bin. This will create a NAND backup of your 3DS.

Wait for the backup to finish, then turn off your 3DS. Find NAND.bin on your SD card and transfer it to your PC for safe-keeping (seriously). You don't need to keep it on your SD card.

Continue to Section 3.

Section 3 - Launch rxTools for the first time!

To launch from the internet browser: boot up your 3DS
Open your 3DS internet Browser and go to https://dukesrg.github.io/?rxTools/sys/code.bin (you should bookmark this. To do so, turn off your WiFi, then attempt to connect to the URL. It will fail; now you can open the browser menu and bookmark it.)
If it fails or gives you an error, click the wrench icon and clear cookies and history before trying again. If that doesn't work, clear all save data as well (should be at the very bottom of the browser settings).

To launch from the Homebrew Launcher, just select RxTools from the HBL.

To launch from Menuhax + CTRBootManager, don't press anything while your 3DS is turning on.

Hold L when the bottom screen glitches to get into the menu if it is sending you back to the homemenu!!!

It should show you an Installation Data Suite. Press A when it completes; it should then tell you that EmuNAND is not found; this is normal, we didn't create EmuNAND yet.

So now that we know that it works, turn off your 3DS and continue to Section 4.
If you have Homebrew Launcher access, follow Section 4b.
Else, follow Section 4a.

Section 4a - Installing a CIA Installer
Only for users without a Gateway card or Homebrew Launcher access

Adapted from this thread (thanks @d0k3 and co.!)
Please visit that thread if you have any issues with this section.

In the web browser, go to is.gd/loadd9wip to launch Decrypt9WIP.

Navigate to SysNAND File Options and then Dump Health & Safety. Let the process finish.

Turn off your 3DS.

Go back to your 3DSCFWKIT_V3.00-STABLE folder and open the PC_Apps folder.

Open the UniversalInjectGenerator folder.

Insert your 3DS SD into your PC.

Find the hs.app file on your SD and place it in the Input folder that is inside the Inject Generator folder. There will be a BigBlueMenu.cia already in there.

Run go.bat. If there are no issues, you will find that there are two inject-ready .app files in the Input folder.

To finally inject BigBlueMenu into SysNAND, rename the BigBlueMenu-with-banner.app file to hs.app and place it on your SD, overwriting the one that is already there.

Launch Decrypt9WIP again, and navigate to SysNAND File Options.

Choose health&safety inject to inject the hs.app. Don't worry, it's not as dangerous as you may think.

Now, launch the rxTools menu (hold L during launch), and boot RXMODE SysNAND.

You will be booted to what appears to be regular SysNAND.

Navigate to the H&S app and it should now be the BigBlueMenu app (Title Manager)!

Launch BigBlueMenu.

Go to the SDMC tab. Basically, this is your SD card it is looking at.

Navigate to the CIAs folder and install DevMenu_2x.cia and old3DS.AGB_FIRM.Patch.cia (if this one doesn't let you install, you can use the DevMenu app to install it)

You just installed your first CIAs!

Continue to Section 5 now.

Download FBI.cia

1. Boot up your 3DS and launch rxTools. Hold L when the bottom screen glitches to get into the menu.

2. Press dpad RIGHT to go to Advanced Options -> Press A -> Install FBI -> Press A -> choose EMUNAND, then select "check TMD version".

3. Take note of the console region and the TMD version, and turn off your 3DS.

4. Open the rxtools download and open the "Tools/fbi_injection/[region]/[version]" folder and copy the "fbi_inject.app" and "fbi_inject.tmd" files to the SD card root dir.

5. Put the FBI.cia from the FBI download onto your sd card

6. Boot up your 3DS and launch rxTools. Hold L when the bottom screen glitches to get into the menu.

7. Press dpad RIGHT to go to Advanced Options -> Press A -> Install FBI -> Press A -> choose EMUNAND, then select "Install FBI". When it's done, it will ask what you want to do with the source. Select "keep" if you want to install FBI to sysnand later.

8. Now, return to the rxtools main menu and select RXMODE -> EMUNAND and launch the Health & Safety Information app, it should boot FBI instead

9. Select FBI.cia and press A to install it.

In your SD card, there should be a Nintendo 3DS folder. Open it, and open the folder inside that (has a long name of random numbers and letters); that is your Sysnand's ID folder.

If there are two or more ID folders, then do the following steps for both folders. One folder is for your Sysnand and the other is for your Emunand; if there is another similar folder, it probably belongs to another 3DS that you inserted your SD card into. Ignore the "private" folder if there is one.

There should be another folder within, so open that too. You should now see an "extdata" folder. If you don't see a "dbs" folder as well, download this zip folder and put the "dbs" folder beside the extdata folder.

*Again, if the dbs folder already exists, and you have a title.db and import.db file inside, do not replace them!

Should look similar to this:

Now, boot the 3DS/2DS and go into Settings —> Data Management —> Software. It’ll ask to reset or repair your software management information or sd card, so allow it to do so. Do this in Sysnand and Emunand!

10. You should now have a new FBI app on your home menu, use that to install your CIAs!

Section 4b - Installing a CIA Installer
For users that have Homebrew Launcher access

If you are not using Menuhax+CTRBootManager to access the HBL:

Boot the HBL, and select Pasta CFW Loader or Mini-Pasta (Try Mini-Pasta first)

Once you boot into Pasta (which looks like your regular 3DS HOME menu), run the HBL again and this time select the FBI homebrew application.

Next, navigate to the CIAs folder and install Devmenu_2x.cia

Switch Destination to NAND and install old3DS.AGB_FIRM.Patch.cia.

This installs Devmenu_2x (for installing CIAs from the HOME menu) and the AGB_FIRM Patch (for playing GBA games) to your sysnand.

If you are using Menuhax+CTRBootManager to access the HBL:

Turn on your 3DS and hold SELECT when the bottom screen turns white, and keep holding until the CTRBootManager menu comes up.

Select MiniPasta.

After you press A, hold SELECT again when the bottom screen turns white, and keep holding until the CTRBootManager menu comes up again.

This time, select Homebrew Launcher.

Once in the HBL, launch FBI.

Navigate to the CIAs folder and install Devmenu_2x.cia

Switch Destination to NAND and install old3DS.AGB_FIRM.Patch.cia.

Done, simply hold the power button to turn off your 3DS.

Continue to Section 5 now.

Section 5 - Creating EmuNAND!

We will now create EmuNAND!

Backup your SD card now.

Launch EmuNAND9 again.

To launch EmuNAND9 using the web browser:
Open your 3DS web Browser and go to is.gd/loade9 to launch EmuNAND9.

To launch EmuNAND9 using the Homebrew Launcher:
Boot the HBL and select EmuNAND9.

Once in EmuNAND9, navigate to Complete EmuNAND Setup. Ignore the starter.bin warning and follow the instructions. Wait for the EmuNAND creation process to finish.

Once that's done, you can put all your SD card contents back on your card.
You don't need to put NAND.bin back on your sd card unless you want to downgrade to 4.X (not recommended).

Section 6 - Unlinking your NANDS
Using the recommended method of formatting SysNAND

We will now unlink your NANDs. But first, some information.

The benefits of unlinking your NANDs:

You will not have to unwrap all your games whenever you enter emuNAND.

This doesn't happen to everyone, but if it does, unlinking your NANDs will stop this from happening.

In the past, some users have reported their sysNAND updating even though they were sure they updated emuNAND. These same people happened to have linked NANDs. We don't know if it is related but it is safer unlink your NANDs if you fear this may happen to you.

You can go into sysNAND's Data Management (found in the System Settings app) safely.

Doing this while your NANDs are linked will result in your emuNAND games, saves, themes, etc. being deleted.

The disadvantages of unlinking your NANDs:

If you want to play GBA games in emuNAND, you will have to install the GBA game in both NANDs, taking up double the space.

If your NANDs are linked, you only need to install GBA games in sysNAND once.

Your sysNAND will be formatted.

Don't worry, everything that was on your sysNAND is in emuNAND instead.

If you don't like this, you can always use EmuNAND9 tool to restore your NAND.bin, thus recovering all your sysNAND stuff.

Now finally, how to unlink your NANDs:

Download TinyFormat

Place the .cia in your SD card (CIAs folder if you want to be organized)

Boot into rxmode SysNAND

Don't know how? Hold L when booting rxTools to get into the menu. From there you can select which rxmode you would like to access. Note: 2.5.2 users have to hold R instead.

Once you're in the HOME menu, launch BigBlueMenu, Devmenu_2x, or FBI

Install the TinyFormat.cia

Press HOME and choose to launch TinyFormat

Follow the instructions to complete the formatting of SysNAND, and thus unlinking your NANDs

Turn off your 3DS after the process is finished

Reboot your 3DS and complete the Initial 3DS Setup.

NANDs are now unlinked!

How unlinked NANDs may look like on your SD card:

On your SD card, open the "Nintendo 3DS" folder.
The folder with the smallest size and random numbers/letters belongs to your sysNAND. This is your sysNAND's ID folder.

Go back to the 3DSCFWKIT_V3.00-STABLE folder and copy the dbs folder to this directory:
SysnandIDFolder/RandomNumbersAndLettersFolder/

If there is a "dbs" folder already, you are in the wrong ID folder!

Don't worry, it is normal that the two files are 0KB!

Lastly, boot up your 3DS/2DS and go into Settings —> Data Management —> Software. It’ll ask to reset or repair your software management information or sd card, so allow it to do so.

Section 7 - Updating EmuNAND!

If you have an update nag on sysnand, follow these short steps to delete the update from your system first, reducing any risk of updating sysnand to be EXTREMELY unlikely. Do not do step 4 obviously, click "no"!

To update your emunand, only do so through the System Settings app.
Do NOT update if it asks you if you're "ready to start system update" or whatever it says whenever you boot your 3DS. Also, NEVER update through the eShop. It will update your sysNAND instead.

If you need Emunand tool (for backing up and restoring your emuNAND if you ever need to), then you can find it here.

How to properly update emuNAND on an O3DS or 2DS:

Boot into Emunand, and launch System Settings.

Make sure it says RX-E or RX3D in front of the version number to be sure that you are in emuNAND

Do NOT exit System Settings at this point or you will be kicked back to sysNAND!

Press Other Settings

Scroll to the right until you see System Update

Press System Update and accept

When it is done, your 3DS will reboot into sysNAND

When you launch rxTools and boot into emuNAND, you will see that it is now updated to the latest version

Let's recap.

This is what we've done up to this point:

We set up rxTools for accessing via the browser or the Homebrew Launcher - this is not the only way to access rxTools, and it is actually the most inefficient way to do it. Read the Menuhax (recommended) or MSET section to learn more!

We made a NAND backup - this is important in case you ever brick your 3DS.

We injected/installed BigBlueMenu to SysNAND and used it to install Devmenu_2x and the patched AGB_FIRM - this is beneficial because:

You can use it to install GBA and DSi games

You will always have a CIA installer when you update your EmuNAND.

We created EmuNAND.

EmuNAND provides a layer of protection, which helps prevent our SysNAND from being updated or bricked.

We unlinked our NANDs in order to avoid certain issues.

We have updated EmuNAND to the latest version - this allows the highest game compatibility, and eShop access.

----------------You are now ready to install CIAs! Read further to learn about RxTools' other features and capabilities!----------------

How to install Games, Updates, Patches, DLC, Homebrew, etc. using BigBlueMenu / Title Manager / BBM / Devmenu

Download any .cia file. Don't ask where to get them. There is a certain iso site for 3DS games that you can find on Google.

Place the .cia file(s) on your SD card. I recommend placing them in a CIA folder to avoid clutter.

Open RXMODE EmuNAND or SysNAND (depending on which nand you would like to access the .cia from).

Launch BigBlueMenu / Title Manager, or any other CIA Installer that you have installed.

Go to the SDMC tab.

Go to the location of the .cia file(s)

Highlight the .cia and press A.

Press A once more to confirm the installation.

Wait for it to finish.

If you want to delete the .cia file after installation (since it isn't needed anymore once installed), highlight the .cia and press X, then A to confirm.

Press HOME and you should get a notification that you have a new app.

This only happens if it's a new game, app, or homebrew that you installed. There is no notification if you just installed DLC, a game update, or a System App.

Unwrap the gift and enjoy!

DSi/GBA/NES/etc. support

The patched AGB_FIRM is no longer needed (although in this guide, we already had you install it just in case

DSi games can be ran through sysNand, and reportedly emuNand as well. Install to sysNand to play them in sysNand; install to emuNand AND sysNand if you want to play them in emuNand. DSi cias must be installed to NAND destination (if using FBI).

GBA games can be ran through emunand, or sysnand. They still have to be installed to both emunand and sysnand if your nands are unlinked! GBA games should be installed to SD (if using FBI).
Personally I just install them to Sysnand and play them from there.

Have a DS flashcard?

If you have a DS flashcard that was able to be used on a 3DS at some point before Nintendo blocked it, you may be able to use it again! Note: The following method will not work for old DS flashcards that were blocked since the release of the original 3DS.

Note: You need to use a CIA installer other than BigBlueMenu. Use FBI or Devmenu_2x
Please read the Understanding FBI at the very bottom of this guide before using FBI.
If you don't want to read that, use Devmenu_2x, it is simpler to use.

On your 3DS:

Launch RxMode Sysnand and open FBI or Devmenu_2x.

If using FBI: Press L to change Destination to NAND.

Navigate to the CIAs folder.

Select DSFlashcardWhitelistPatch.cia and press A to install it.

If using FBI: Choose to overwrite the title when it prompts you.

Once done, exit the CIA installer.

You should now able to use your DS flashcard on your 3DS.
Things to note:

If your DS flashcard still doesn't work, then it will probably never work on your 3DS.

You should be able to use your DS flashcard in any mode (Sysnand, RxMode, Devmode/Pasta Mode), but exiting the card will bring you back to regular sysnand.

Running a DS flashcard will remove your MSET exploit if you have one (see the next section).

You can use a DS flashcard to easily install the MSET exploit (see the MSET section).

Launching rxTools at Boot - Menuhax!

These steps will setup Menuhax, which we will configure to allow rxTools to boot the moment you turn on your 3DS/2DS! IMO this is the best way to launch rxTools.

Note: You must be on 9.0 - 9.2 firmware. This means your sysnand has to be on or between 9.0 to 9.2 system version. To update to 9.0 or 9.2, scroll down to the section How to Update your 3DS/2DS to 9.0 or 9.2 and follow the instructions, then come back here.

Second note: This will only work with rxTools 3.0 nightly (from September onwards I think). No one has found a way for it to work with rxTools 2.6 and under as far as I know. The rxTools build included in Section 1 works with this.

Set a random theme on your 3DS, then change it back to the default theme.

Launch rxmode SysNAND (Hold L when booting rxTools to access it)

Open BigBlueMenu (or any other CIA installer)

If you already have access to the Homebrew Launcher, skip to step 8!!

Install hblauncher_loader.cia (it's in the CIAs folder)

Exit to the HOME menu; there will be a new gift. It is the Homebrew Launcher cia.

Launch the Homebrew Launcher via the Homebrew Launcher cia you just installed in SysNAND.

In the Homebrew Launcher, run the menuhax_manager installer and install menuhax.

After all that, test if menuhax boots you into the homebrew menu at cold boot. Just turn off your 3DS and turn it back on, and don't press any buttons.

On your SD card, look for the file which name starts with "ropbinpayload". Open it with HxD (included in the PC_Apps folder) or Notepad++. Maybe plain old Notepad will work too.

Press CTRL+F and search for boot.3dsx. There will be two results.

Change both to auto.3dsx and save the file.

When you turn on your 3DS, you should see the bottom screen flash multiple colors, followed by the rxTools splash screen.
The Menuhax button config is as follows:

Menuhax loads if no buttons are held at boot.

Menuhax does not load if any button is held at boot.

Additionally:

If you hold L after the bottom screen turns white, you will boot into the rxTools menu.

If you hold SELECT after the bottom screen turns white, you will boot into the CTRBootManager menu.

Launching rxTools through the System Settings app - MSET!

These steps will downgrade your System Settings in your sysNand to the 4.x or 6.x version, which is where we will install the exploit. It is the second best entrypoint to booting rxTools, in my opinion.

Note: You need to use a CIA installer other than BigBlueMenu. Use FBI or Devmenu_2x
Please read the section Understanding FBI at the very bottom of this guide before using FBI.
If you don't want to read that, use Devmenu_2x, it is simpler to use.

All users:
Want to launch rxTools via MSET so that you don't need to connect to the internet? Select your system version:

4.X

Use one of the following methods:

EASIEST METHOD: If you have a DS flashcard that works on your 3DS, open the MSET folder in the rxtools download and put the .nds file (rxinstaller.nds) on your DS flashcard's SD card. Now run it with your DS flashcard and select "rxtools 4.x".

To install MSET with FBI, you need to have FBI 1.4.14 or higher on your sysnand. Simply launch rxmode sysnand, launch FBI, and press SELECT. Now, select "rxtools3.x 4.x". MSET should now be installed.

To install MSET with the internet browser, simply put the rxinstaller.bin (from the MSET folder) on your SD card root. Then launch the browser and go to http://dukesrg.github.io/?rxinstaller.bin or http://dukesrg.no-ip.org/3ds/cakes/?rxinstaller.bin . It should freeze and crash, and send you back to the home menu. MSET should now be set up.

To launch rxTools via MSET, just turn on your 3ds, go to System Settings-> Other Settings-> Profile-> Nintendo DS Profile, and rxTools should boot.

5.X

If you don't have a DS flashcard: grab the rxinstaller.bin for rxTools from the "mset" folder and put it in your sd card root.

Go HERE (click the "CIA Format DLC's, Themes & Updates" link. Name of the thread is "[MEGA] [CIA/BIN] MSET 4.X & 6.X backups, Browser backups, Update packs (All Regions)")

Download one of the following cias according to your region:

MSET-USA-4.0 0004001000021000
MSET-EUR-4.0 0004001000022000
MSET-JPN-4.0 0004001000020000

Place the .cia anywhere in your sd card.

Launch RXMODE SysNAND (Hold L when rxTools is booting to get into the menu first)

Launch Devmenu_2x or FBI

Install the .cia you downloaded above and then exit to the HOME menu.

EASY METHOD: If you have a DS flashcard that works on your 3DS, open the MSET folder in the rxtools download and put the .nds file (rxinstaller.nds) on your DS flashcard's SD card. Now run it with your DS flashcard and select "rxtools 4.X DG". Then skip to step 11!

Note: the "DG" beside the system version number means "downgraded".

Open the 3DS browser, and enter this URL: http://dukesrg.github.io/?rxinstaller.bin or http://dukesrg.no-ip.org/3ds/cakes/?rxinstaller.bin

Wait for a bit (it should crash and send you back to the home menu). If it doesn't crash after a minute, press HOME and it should crash.

If the next step (8) doesn't work, try clearing your cache and history before entering one of the above links.

Now you can launch rxtools by going to System Settings-> Other Settings-> Profile-> Nintendo DS Profile

6.X

If you don't have a DS flashcard: grab the rxinstaller.bin for rxTools from the "mset" folder and put it on your sd card root.

EASY METHOD: If you have a DS flashcard that works on your 3DS, open the MSET folder in the rxtools download and put the .nds file (rxinstaller.nds) on your DS flashcard's SD card. Now run it with your DS flashcard and select the 6.X MSET option. Then skip to step 4.

Note: the "DG" beside the system version number means "downgraded". So if you are on 9.x using the 6.x mset, you would use "6.x DG". If you are on 6.x system version, you would use simply "6.x".

If you have FBI installed in sysnand, you can run it, press SELECT, and choose "rxtools3x 6.x" to install the exploit. Then you can skip to step 4.

If you used a DS flashcard in step 1, then skip to step 4! Open the 3DS browser, and go to one of these URLs: http://dukesrg.github.io/?rxinstaller.bin or http://dukesrg.no-ip.org/3ds/cakes/?rxinstaller.bin

Wait for a bit (it should crash and send you back to the home menu). If it doesn't crash after a minute, press HOME and it should crash.

If the next step (4) doesn't work, try clearing your cache and history before entering one of the above links.

Now you can launch rxtools by going to System Settings-> Other Settings-> Profile-> Nintendo DS Profile

7.X - 9.2

If you don't have a DS flashcard: grab the rxinstaller.bin for rxTools from the "mset" folder and put it on your sd card root.

Go HERE (click the "CIA Format DLC's, Themes & Updates" link. Name of the thread is "[MEGA] [CIA/BIN] MSET 4.X & 6.X backups, Browser backups, Update packs (All Regions)")

Download one of the following cias according to your region:
6.X MSET (2DS users must choose one of these or you may brick your 2DS!):
MSET-USA-6.0 0004001000021000
MSET-EUR-6.0 0004001000022000
MSET-JPN-6.0 0004001000020000

4.X MSET:
MSET-USA-4.0 0004001000021000
MSET-EUR-4.0 0004001000022000
MSET-JPN-4.0 0004001000020000

Place the .cia anywhere in your sd card.

Launch RXMODE SysNAND (Hold L when rxTools is booting to get into the menu first)

Launch Devmenu_2x or FBI

Install the .cia you downloaded above and then exit to the HOME menu.

EASY METHOD: If you have a DS flashcard that works on your 3DS, open the MSET folder in the rxtools download and put the .nds file (rxinstaller.nds) on your DS flashcard's SD card. Now run it with your DS flashcard and select "rxtools 4.X DG". Then skip to step 11!

Note: the "DG" beside the system version number means "downgraded".

Open the 3DS browser, and enter this URL: http://dukesrg.github.io/?rxinstaller.bin or http://dukesrg.no-ip.org/3ds/cakes/?rxinstaller.bin

Wait for a bit (it should crash and send you back to the home menu). If it doesn't crash after a minute, press HOME and it should crash.

If the next step (8) doesn't work, try clearing your cache and history before entering one of the above links.

Now you can launch rxtools by going to System Settings-> Other Settings-> Profile-> Nintendo DS Profile

How to Update to a Newer rxTools Version

Download the recommended RxTools build for this guide here
Download Python version 2.7 if you don't have it

Direct Windows installer link

If you are using Windows, right-click the rxtools.rar and open Properties. If at the bottom, it says the file is blocked, check "Unblock" and Apply. This should take care of any problems you have with the following steps.

Backup and delete any "rxtools" folder that you may have on your SD card before doing the following steps!

Place:
1. the "rxtools" folder on the SD card root.
2. the "firm" folder inside of the "rxtools" folder. How to get it:

Run cdn_firm.py in the "Tools" folder. It will generate a firm folder in the same folder that cdn_firm.py is in. The firm folder must go into the rxTools folder like so: SD:/rxtools/firm

For ninjhax users, you also need to replace the rxtools.3dsx and rxtools.smdh found inside the ninjhax folder in the rxtools download zip.

How to Update your 3DS/2DS to 9.0 or 9.2

If you want to boot rxTools as soon as you turn on your 3DS, then you need to set-up Menuhax; and to use Menuhax, you need to be on 9.0 - 9.2 firmware.
Warning: This can brick your 3DS if done incorrectly! Be sure that you follow the instructions carefully!

Requirements:

BigBlueMenu installed in sysnand (Section 4 if you don't have Gateway or Ninjhax) OR any other cia installer on Sysnand.

A rxTools 3.0 nightly (preferably the one linked in Section 1)

Also works on rxTools 2.5.2 (for those that can't launch 3.0)

Let's get started.

See AidanLumina's tweet here and click Files for downgrade/manual update.

Download one of the O3DS 9.2 packs

Once downloaded, open the archive and find the "updates" folder; place it on your SD card. There should be many cia files in that folder.

Example: SD:/updates/0004013000008003.cia

Download Sysupdater

Open the archive and put sysUpdater.cia on your SD card

Insert your SD card in your 3DS

Hold L while launching rxTools to get into the rxTools menu. If using rxTools 2.5.2, hold R instead.

Press DPAD RIGHT until you highlight ADVANCED OPTIONS, then press A. Skip this step if using rxTools 2.5.2

Go down to DEVMODE or PASTA MODE and press A

After a few seconds, you should now be in sysnand; firmware spoofing is disabled but cias can still be launched in this mode.

Launch you CIA installer

Install sysUpdater.cia (Destination: SD if using FBI)

Once installed, press HOME to see sysUpdater wrapped as a gift; unwrap it.

Launch sysUpdater

sysUpdater will ask you if you are sure you want to go ahead with the update; choose to accept it.

It will also tell you that you shouldn't be in Gateway mode, or have firmware spoofing. Do not worry about this, DEVMODE / PASTA MODE has no firmware spoofing, so sysUpdater will work as intended. Just be absolutely sure you are in DEVMODE / PASTA MODE (line 13), not RXMODE SYSNAND!

Wait for sysUpdater to finish. When it is done, your 3DS will reboot into 9.0 or 9.2 firmware! You can now follow the steps to use Menuhax if you'd like.

Click HERE

Click the CIA Format DLC's, Themes & Updates [Archive] result

Click View Full Version : CIA Format DLC's, Themes & Updates at the top of the page

Find the thread titled [MEGA] [CIA/BIN] MSET 4.X & 6.X backups, Browser backups, Update packs (All Regions)

Scroll down to the section titled Updates

Download either the 9.2 modified update pack for your region, or a 9.0 or 9.2 Full Update Pack for you region

How to move Games, Saves, Themes, and Emunand to a new SD card

Get Emunand Tool

Insert your old SD card in your PC

Open Emunand Tool and select "Extract EmuNAND"

Save it somewhere on your PC (as "emunand.bin" if you want)

Backup all your SD card files to your PC

Eject your old SD card

Put Gateway's launcher.dat on your new SD card

Format emunand on your new SD card via the gateway menu

Turn off your 3DS

Insert your new SD card in your PC

Open Emunand Tool and select "Inject NAND to emuNAND"

Select the emunand.bin you made in step 3 & 4

Close Emunand Tool when done

Put backup of SD card files (from step 5) on your new SD card

Done, emunand and files (saves, games, etc.) have been transferred to your new SD card!

Understanding FBI

Unlike other cia installers, FBI allows the user to install to either Nand or SD. 3DS games, game updates, DLC, GBA games, and homebrew, are meant to install to SD. System titles (such as the Internet Browser, or MSET), and DSi games install to Nand. To better understand Nand and SD destination, take a look at these infographics, courtesy of @pakrett and @Hashtastrophe respectively:

-----------------------------------------------------

F.A.Q

If you get the "022-2634" when trying to access the eShop on the latest EmuNAND, try this (thanks to @Nestar):

1. Backup your emuNAND.
2. Backup all emuNAND files (ticket.db etc.) with rxTools.
3. Backup the content of your SD card.
4. Format emuNAND.
5. Recover your SD card content and boot rxTools in emuNAND.
6. Update to 10.3.0-28X and boot into emuNAND again.
7. Go to system settings and to NNID at the top; follow instructions.
8. Boot emuNAND and start the eShop; simply restart the 3DS if it keeps looping after the password input.
9. Once in the eShop, close it and shut down.
10. Recover your whole SD card once more. *
11. Inject emuNAND backup.
12. Inject all emuNAND file backups.
13. Start the eShop in emuNAND and it should refresh your software.
14. And now you should have emuNAND eShop access without any loss ofStreetPass/Save/Friend/etc. data.

jorgeluisrochas · Jan 15, 2016

After retry the steps for a couple of times, it's finally done. O3DS 9.2, rxTools 3.0 and autobooting by menuhax. Thanks for this great tutorial!
Also, I easily put back all my sysnand stuff using Decrypt9 to restore it with with my nand.bin file.

I had a simple issue with the menuhax autoboot, giving a black screen after try to autoboot rxTools. So I changed the timeout in CTRBootManager to 1, now when I don't hold any buttons, autoboot loads for a second the CTRBootManager menu and redirects automatically to the rxTools screen.

I readed on another forum thread that when we try to update a .cia with the shop it gives a error, probably because we have the game on the system, but there's no information on Nintendo Eshop about this "purchase".

You can better donwload a .cia with the update for your .cia game.

RitchieRitchie · Jan 15, 2016

Any advice appreciated - if I have a gateway mset already set up do I need to use the rxinstaller file on my ds flashcart?

cheers!

How would I use the cfw kit 4.0 update? Do I just paste it onto the root? Also, what is installMii? I think it is a homebrew app.

Best way to do this:
Extract both the kit and the update into a folder each, then merge those folders and put the content of the resulting folder onto your SD card.

Mr White · Jan 15, 2016

I'm having issues with section 4 of this tutorial.

I have HomeMenuHax, so my 3DS will boot straight into Homebrew launcher when it's turned on, but I can't get the CTRBootManager menu to come up. The boot.cfg file says I'm supposed to hold the select key, but it just goes straight to Homebrew Launcher.

What should I be doing to get this to work?

Is there any real point in updating to the latest 4.0 build if you're happy with the one you have already installed (for me rxTools_2015-12-05_08.48-a08cfdd)? Are there any benefits?

cheers!

Thank you. Also what does install mii do.

LiquidFenrir · Jan 15, 2016

Hello! I'm new to the CFW thingy so I have some questions:
1.Can I play online/local multiplayer with .cia games? I don't have a Gateway.
^I did some research but could only find people unable to play MK7
2.Is it legal to download/use the files of games if you already own them?

And longer:
I plan on buying a New 3DS, transfer the data from my old 3DS, downgrade the old from 10.3 to 9.2 and then install rxtools.
3.Do I risk not being able to if I wait for next month (update breaking the HBL/SysUpdater)?
