Hacking Restore A9LH Nand backup on B9S

[raphamotta]

So I have a Nand Backup that I did with Hourglass9 on 11.4 FW when I had A9LH. I'm now on B9S and want to restore this backup.

Can I do it without problem?
Can I use the hourglass9 firm version for it?

That's indeed a very good question.

For what reason do you want to go from B9S back to A9LH?

Most likely, they want to restore the backup but keep B9S. I doubt anyone with it would remove it.

Yes just want to restore my backup. I don't know if I gonna lose B9S with this, or mess the system.

You could try it and post the results

Hourglass9 is designed to restore backups without removing A9LH so restoring a NAND backup should not remove B9S either. also it was updated a few days ago for use with sighax so it now has a FIRM payload to use.

EDIT: Use Godmode9, this is listed under the features (B9S is sighax when it comes to NAND restoring so it will work)
https://github.com/d0k3/GodMode9/releases

Restore NAND dumps while keeping your A9LH / sighax installation intact: Select Restore SysNAND (safe) from inside the A button menu.

@raphamotta I wouldn't do what @Oleboy555 suggested unless you have a hardmod and a backup of your system with B9S.

Wait until somebody with a hardmod does this

Yeah I don't want to turn my 3DS into a brick. That why I asked here. Maybe @Plailect can answer that, or @d0k3 .

NAND Restores with Hourglass9 or GodMode9's Safe NAND Restore function do not overwrite the FIRM partitions (where B9S is stored). Yes, you could restore this backup.

With Decrypt9WIP, you can. Pick NAND restore or forced, and not 'keep a9lh'.

I made it without problem
even by keep a9lh or not

 

[StevenLexon]

use godmode9 to restore

I installed b9strap, then restored my first a9hl nand backup and everything works as normal, I still have boot9strap installed
