I recently bought an M3 real device from modchipcentral and I'm not too happy with it right now. It didn't even come with a CD-rom. The firmware loads up fine, however, whenever I try to load any DS backup the screen flashes white and freezes. Some games freeze on a black screen. I've downloaded several versions of the firmware........ I assumed that this was a contact issue, tried the paper trick, didn't work. I've tried 5 separate backups, none work. Does anyone have any assumptions or tips for me?
