    possibly in your closet
    You might be able to backup your NAND, and restore it without (keep A9LH) to remove A9LH from your device.

    (I am not sure - I am not responsible for anything that goes wrong or anything that happens to your system)

    I was just wondering if I ever needed to sell it. I guess I could just list it as cfw

    Just back up the nand, then restore it without the A9LH option, and boom, you're back to legit booting without A9LH.

    are you guys sure? because i was under the impression that you HAD to have a pre-A9LH backup to remove the hack. because backing up your NAND also backs up the A9LH entrypoint, if i recall correctly. i think that's why decrypt9 says "corrupted firm0/1" when restoring a nand backup of an A9LH system.

    3DS Safe mode will remove it still, right?

    just try what i suggested above. I did it successfully by accident, by flashing a sysNAND backup without choosing the (keep A9LH) one, but luckily I just flashed it again with the correct method.

    it will work if your sysNAND backup didn't have A9LH in the first place. but i don't think this will work if the only backup you have is your current A9LH setup.

    No, it was not. It should work just fine for removing A9LH if using O3DS/2DS.

    OP: According to a previous thread, https://gbatemp.net/threads/how-do-i-remove-a9lh.418022/, another method, if possible for you, would be to simply install the original NATIVE_FIRM via CIA, that corresponds to your system version, using a CFW that doesn't write-protect it.
