Tutorial Simple Guide to Downgrading your 3DS

[meinhard]

Just downgraded n3ds 10.3.0-28E on first try using ninjhax 2.5 (sysupdater booted on 3rd try)...all went well and no black screen on boot after downgrade (probably because i had not menuhax)

 

[probablygay]

If I'm on a 9.9.0-26E N3ds (non XL), what is the best/safest way to downgrade? Also, how can I check which version of Menuhax I'm running? Should I update to 10.3 and then downgrade to 9.2, or just downgrade from 9.9.0-26 to 9.2? Just trying to eliminate as many variables to avoid screwing up.

Got a big MicroSD during lunch today. Would my steps just be go into emunand, dump emunand to emunand.bin, copy my current SD on my computer, set up emunand on the new SD and then move everything back over?

 

[dradonhunter11]

So is it safe to do it on O3DS or should I wait? I have fbi injected game on it

Quick question my 2ds already has emunand can I use that SD card on both systems with the same emunand?

I succesfully managed to downgrade to 9.2.0-20U on my O3DS but I can't launch Ironfall anymore!

Help?

 

[workingpapi]

if it doesn't install SAFEMODE first

i'm not trying that

Couldn't tell, sorry! I was just saying, as I see a lot of people (including me) struggling with the error (Unable to get CIA fileinfo) and this version of the homebrew worked the very first time.

Odd on his twitter he stated "Be careful if you build latest KTM. It now has libsu so IT CAN ACTUALLY DESTROY YOUR NAND." But ok....

Ironfall requires 9.5FW to run. In the mean time, you can use browserhax.

No, because NANDs are encrypted with keys that are unique to a specific console.

Your 2DS NAND will only work on your 2DS, and your other one will only work on that one. This applies for both SysNAND and EmuNAND.

Should I update to 10.3 before doing this or just downgrade from 9.9.0-26E?

If I were you I'd downgrade right from 9.9.

Hey everyone, got a problem, mind if I ask?
The downgrade seem to be finished, it did reboot after 10 seconds (After the msg). However, I got the black screen and the "Error turn off the console" screen.

Thought it was Menuhax, but removed the sd and turned on, same error. Then removed the sd mid-turning on but still got the error screen. I do not understand why. I still can enter to recovery mode though. Is my 3ds downgraded? Is there something should I do?

Using latest Julian sysUpdt, on O3DS 10.3U

 

[Sparked963]

Been around 7 hours trying to downgrade my O3dsXL. No luck and around 25+ soft bricks. Tried reformatting and everything and using 9.0 and 9.2 with different sysUpdaters
Guess i'll wait for something

 

[probablygay]

If I were you I'd downgrade right from 9.9.

Thank you. One last question: Is it safer to downgrade using something like OoTHax or Menuhax or does it make a difference? Do I need to worry about any extra steps if I'm using an EU N3DS nonXL?

 

[averageguy]

Ironfall requires 9.5FW to run. In the mean time, you can use browserhax.

Can't launch it either. When I directly access to http://yls8.mtheall.com/3dsbrowserhax_auto.php on the browser (After initializing save data) nothing happens

Honestly, besides Ironhax (which seems to have the highest fail rate in downgrading), I don't think it matters. Also, no, there's no extra steps for an EU N3DS. Only JP models.
