Hacking n3dsxl crashed and only boots in gm9

[HammerStix]

While playing fire emblem warriors on my n3dsxl, I encountered visual glitches before the whole system crashed with an "an exception occurred" error. It booted into gm9 but no matter what I do, every button press except for start, zl, and zr causes gm9 to reboot

Try downloading luma and put new copy on root of sd. Maybe it corrupted. Try with no sd card in to see if luma on ctr nand works

I have a similar issue

I appreciate the help but it turns out the start button got jammed somehow so it's forcing the gm9 boot
