    What I'm thinking is going the route of sysupdater, but there are so many different versions now... I wouldn't know where to start. Seems fixable because only the homemenu is broken. But other than that...
    What I strongly advice you is NOT to install system firmware titles from FBI.

    Its because you need the home menu to load this. All apps/games runs on the background of the home menu.

    Edit: I dont get its why the fbi loads at all and only it.

    My guess is that it only loads because it's the first title on his list, luckily its this and not an useless game. If it was a game i'd know no way of fixing this.
    Another question, do you have a nand backup from before you did a9lh? or did the people that did the downgrade not give you any of these files?

    I cant assure you its gonna work. but if you have a9lh you can: Decrypt9 -> make backup. DEcrypt9 -> load another backup(frm a time where your home menu was working). Then test it.

    IF you dont have backup, than it would need to search for the home menu title, download it, put on sd card, delete home menu tittle and re-install it. Note that after you delete your ohme menu you CANT TURN IT OFF or it will brick the next time you try to turn it on. You must reinstall it without rebooting the system. Anyway I cant tell for sure if eihter is gona be safe or its gona work.

    But not through FBI, that why I suggested sysupdater. but i don't know which version is the safest to use.
    Before doing anything, please ask in the links i provided. there are people way more adequate to help you solve this at those threads. It's the safest.
    He has no backups, so he can't revert to an older one.

    So this makes me think. Can I set up an emunand on a small card, downgrade it with hombrew, and dump the otp? That way I can just put the first card back in without ever touching the SysNand and tuck the small card away with otp and Nand for safe keeping. For N3DS with OTPless A9LH.

    That doesnt help much, but works as a safe net maybe. Anyway the best you can do is to search some advanced help.

    He has no other options for managing tittles. I think Sysupdater will not Change his home menu because its already the correct title, he is already on 9.2.

    Doesnt work. OTP needs permissions that are granted only during on boot, emunand can not load at this time.

    Remember when people used to get frankenfirms and they had to run sysdowngrader twice?
    I don't know if this can also be done for sysupdater and re-installing the same version.
