Tutorial Simple Guide to Downgrading your 3DS

[vlasp01]

I got it to work with the new sysUpdater for a split second and now the sysUpdater does not even start. Somebody knows what should I do? I re downloaded and it still happens-

Try another exploit maybe. (BrowserHax/MenuHax/IronHax)

Anyone with n3ds can confirm it worked for them?
I plan on hardmodding mine and testing it out.

Wait, I think I misread where you're at. If y didn't do anything you should be fine to retry. If it locks on "getting cia informations" that's when life sucks.

I guess I was really lucky then. Who needs eShop anyway lol

New or old SysUpdater? New as in the one that was linked 10 minutes ago.

New one, failed to verify CIA files first time - just restarted and retried.
also here the stick so it can be seen its a new 3ds & progress

Thanks my good comrade.

I don't really know much about customization or anything, it's just the out of the box new 3ds and I did what was suggested in the OP with the new SysUpdater & menuhax

 

[JershXL]

It's actually doing it, IM SO HYPE

 

[SackThing101]

Alright, restarted it over 5 times and now it's downgrading. Will report back.

 

[Cydget]

How many people have bricked with the newest update?

 

[JershXL]

How long should I wait after it says rebooting in 10 seconds?

 

[SackThing101]

No bricks.

o3DS 10.3, Ironhax and Ninjahax installed

 

[Rodrigo Ruelas]

I got this: "can't force threads to core 1"
and the app doesn't do anything.
what should i do?

 

[Vinix]

Well ... Now sysUpdater simply do nothing even if I press Y, it's just frozen menu.

 

[cocoPika]

can it work on N3DS XL 10.3.0?

Hello!
In recent days, there have been many developments within the 3DS homebrew community, with one of them being kernel access! With this, we now have a way to downgrade 3DSs and do whatever we want with kernel on >=9.3 3DSs. What's that? You want to downgrade? Well then, here's how...

PLEASE NOTE: JP N3DS Users, you'll need to remove the 000400102002CA00 title in order to not get bricked! Not sure if other regions need to do this as well.

ALSO NOTE: Note: So far NO ONE HAS BRICKED THEIR 3DS FROM THIS. HOWEVER, I AM STILL NOT RESPONSIBLE IF YOUR 3DS BRICKS. If it does, I'm sorry, but it is NOT my fault.

Before beginning, remove any DNSs (like Tubehax) that you may have on your 3DS. This can interfere with the downgrading process. You may also want to back up your SD card juuuust in case...

1. Grab the sysUpdater app from here and place it into the '3ds' folder of your SD card.
2. Make a folder called 'updates' on the root of your SD card.
3. Place all of the CIAs for the update you wish to downgrade to into the folder. (I cannot link these for legal purposes. Sorry!)
4. Eject your SD card, put it into your 3DS, and boot.
5. Open up the Homebrew Launcher in your entrypoint of choice and start the sysUpdater app.
6. If everything goes well, you should have some options. Since we're downgrading, you can go ahead and press the Y button.
7. Wait and DO NOT touch anything. The app will tell you when it is done. (It took me less than 5 minutes)
   
8. Once the app prompts you that it is done, wait. It will reboot automatically.
9. Bite your fingernails in suspense. If everything goes correct...
10. Your 3DS will be downgraded!

COMMON PROBLEMS:

Issue: The app freezes at a certain step!
Solution: Try a different entrypoint. I was using Ironhax and got this problem, so I switched to OoT3DHax and it worked.

Issue: The prompt comes on screen, but nothing happens when I press a button!
Solution: Either wait a few moments or reboot the system and try again.

Issue: I downgraded, but my 3DS screen is completely black upon reboot!
Solution: Try removing the SD card, or you can reboot into recovery mode. To do this, hold A+R+L+Up as your 3DS turns on.

(please recommend any other issues and solutions to add here please!)

Quick Question, will this work on the firmware 10.3.0-28U? Sorry for being a noob.

 

[kudofan]

Seems like n3ds users should wait for KTM.

What entry point? I recommend homemenuhax and hbl 2.5

Youre more likely to get a brick

Edit, didn't mean to quote you @hudhair

 

[Vinix]

Browserhax. It's possible to obtain homemenuhax in 3DS 10.3?

 

[einhuman197]

Does this only downgrades some system apps or the whole system version. Will it work on n3ds 9.9.0-26E?
