Hi, i got the M3 Lite (Perfect) Micro SD Card around 2007 and it was always a good one. There was a point when it started to have some issues. I saw, that the contacts are a bit scratched. I totally cleaned the contacts with alcohol and a rubber. That helped a bit to make it read better. When I put a 2gb micro SD into it, most times it normally starts into the menu, it shows the roms, but when I start it the booting process won't finish and it starts showing strange symbols and freezes. So I am wondering, is there a chance to repair it, as it is not totally broken? Other idea is, I could change the battery, I guess it could be empty and if I am lucky, that is the reason, not the contacts or a different error.
