I recently bought a 3ds tried modding it I got up to installing all the mods in the homebrew channel (the one were you press up down left right a. I forgot what it was called) And it went to reboot and I waited for five minutes and it still didn't turn back on so I pressed and held the on button the blue power light and it turned on for a second and turned back (the screens remaned off) on so I took it back to the shop and got a new one does anyone know a guide for the latest software and if the same thing happens how to fix
