Homebrew Uninstall Arm9LoaderHax ?

[Olivier78640]

Nice! I successfully uninstalled Arm9LoaderHax from my Old 3DS thanks to everyone!
Here is how I did it (I even fixed the FBI icon remaining after re-writing to SysNAND):

1 - Made a backup of SysNAND (just in case)
2 - Created a RedNAND
3 - Setted up RedNAND
4 - Got hs.app from EmuNAND with Decrypt9
5 - Injected FBI with Universal Inject Generator
6 - Installed FBI
7 - Installed PlaiSysUpdater and TinyFormat from FBI
8 - Downgraded to 9.2.0-20
9 - TinyFormatted twice
10 - Installed TinyFormat for the last time
11 - Went to Decrypt9 and re-installed the original Health and Safety
12 - TinyFormatted for the last time
13 - Backuped RedNAND to file
14 - Restored SysNAND from the backup (without keeping A9LH of course)
15 - Removed my SD card completely
16 - Enjoyed !

Thanks everyone for helping !

You should keep the OTP for that 3DS on file just in case he ever changes his mind =P

Too late, already deleted If he wants A9LH, he will need to do the whole process by himself

Luma3DS's only does a firm protect if you launch sysnand, not emunand. That's why I ended up doing that from emunand. I should write a tutorial on doing that to get "stock firmware" back onto a 3DS.

Yupz, and thats why i said it, i had to remove a9lh for some testing, and that worked fine

I always keep a backup, even if it is in too many ways

after step 6, how did you load into emunand if on A9LH?

 

[Arkansaw]

Downside of ahl9.. pretty troublesome to reset to factory default and requires 9.2 emunand

 

[Amapola62]

Why not just downgrade sysnand to 9.2 and use the uninstall feature of safea9lhinstaller?

No need to downgrade to 9.2 https://github.com/AuroraWright/SafeA9LHInstaller/commit/1cc678adc3b5125a5565b69323efb7480301bc4f

 

[Amapola62]

Yeah but it's easier to reinstall the hack at 9.2...so...that's why I suggested it...
