So I recently modded my 3DS. I accidentally left Checkpoint running overnight (about 9 hours), and when I tried to close it, my system froze. I held down the power button until it turned off, but when I tried to turn it back on, it gave me that. I can't open the back because the screws are rusted and stripped and none of the tips I've tried have worked. I can boot into Luma and GM9, but nothing else. This is my childhood 3DS and I really want to save it.
