I recently updated to boot9strap from a9lh, and everything was working fine... until I chose to update luma through the lumaupdater app. Although it said "update successful", when I tried rebooting my 3DS, it would not turn on. As of now, when I press the power button, it turns on for about 1 second and immediately turns off (black screen, no speaker popping). I've tried to boot into safe mode, removing the SD card, taking out the battery, etc. but nothing works. What should I do? (I'm a noob so try to be simple with your answers pls)
