Hi guys, can someone help me? My o3ds has arm9 + luma, and it's CFW is updated to 11.2. Everything was working fine until today. Now, it wont turn on! When i press the power button, the screen remains black for 5 seconds, then it makes a noise and it turns off automaticaly. Does anyone knows whats going on? I've already checked my SD card and all files seems to be fine; Should i format it?
