One day, while my 2DS was showing the GM9 boot splash screen, I dropped it. It immediately turned off. When I opened up my 2DS, I figured out that the battery's plugin had come out of the soldered slot, preventing the flow of electricity to the rest of the 2DS. I fixed it and booted my 2DS up again. Now, it shows the blue light and immediately turns off (even without the SD card). Does this mean I have a corrupted NAND? Whether or not this is the case, is there a way I can fix it?
