Recently my micro sd card in my 3ds just decided to corrupt itself for some reason. I tried turning it on without one and with a new one and got an arm 11 error. Even after disabling the arm 11 exception handlers I just get a black screen instead. I've pretty much tried everything I could find like holding L R A and Up while turning it on. I've also tried cleaning the battery as well even though I doubt that has anything to do with the problem. If anyone could help me with this issue I'd much appreciate it since I couldn't find anyone that had a problem exactly like this with the micro sd card being the issue.
