So I managed to get a new 3ds XL at 9.2. Sweet! There's a catch though. If the brightness is at 5 (or higher than 1, haven't tested it and can't test it anymore) the 3ds just totally shuts off. It might display the screen for a bit, but it just shuts off instantly with a pop. When I inserted an SD card that has never been inside it before, it magically worked again, and was at the first brightness level. Is there any way whatsoever to restore brightness level 1 so that it stops shutting down, or am I just basically screwed, and have to open it up and fix it myself?
