What happened is that it got water damaged and everything works fine when i opened it everything looked fine no signs of water corrosion everything on the 3DS works exept it always give me a message saying the SD card is locked and i know for a fact it isnt locked i already tried using 3 different SD cards and none of them are lock protected and yes they are formatted as well. I need help
