    Basically, I thought today of something:

    I have a SysNAND backup with arm9loaderhax v1. Recently I updated to v2.

    So, I'm asking, is there a problem if I restore the backup with the old A9LH?

    Gambia, The
    No no Problem. If you want to go back to v1 uncheck "keep a9lh" when restoring NAND.

    Use Hourglass9 or "Keep A9LH" in Decrypt9. It should leave A9LH alone in that case.

    It won't erase A9LH if his old backup has A9LH on it...
    I wouldn't recommend that. I'm not sure if the "Keep A9LH" option keeps all the A9LH data intact or just the FIRM partition, and if it doesn't, he'll brick his console. Logically it should, but unless you know for sure that it will, it's not worth the risk.

    Thanks guys for the help. But I think you didn't understood something:

    My old backup has A9LH v1 installed. If I use restore with keep A9LH it will only keep my A9LH v2. However, if I don't use "keep A9LH", does it change my A9LH v2 to A9LH v1?

    I'm asking if I brick my console by swapping A9LH versions. AFAIK, You can't use A9LH v1 on SafeA9LHInstaller v2, so that's why I'm asking.

    If you restore the whole backup it's ok, you'll return to A9LH v1

    Why not make a back up with A9LH v2 and replace your A9LH v1 back up with the new one? That would be simpler...

    The only reason I can think of to be on V1 is easy compatibility with GW (the arm9loaderhax Beta #2 from June 1st). This is why I went through the trouble of going back to old versions of the guide and installing v1 on my o3DS, just have one SDcard with Luma3DS and one SDcard with GW. Maybe you can request for an A9LH tool that can do this? If ever made, we'll need an easy foolproof way to update to v3 eventually anyway (and you should have your otp.bin of course).
