So here is the story, my older brother noticed I was getting many Arm11 (Core 0) Errors aton on games, so he went to google and found a video that made me delete the Nintendo 3ds/(the code)/(more code)/extdata/00000000/0000008f folder, that caused my 2ds to glitch out and now I cant turn it on, I bought a new sd card and formated it, but I still need help turning on the system without getting this error. Thanks
