I tried to load new games on my Kingston 1gb micro sd card that i have been using for about a year and now after the passcard boots the screen stays black. The power light is green so I know there is still power and I have removed the sd card and cleaned the contacts and have tried to re-insert it many times to no avail. I was previously using v29 and i have even tried v32 and still nothing happens. My sd card works in my digital camera and in my mp3 player so i do not think that is the problem. The only thing that i can think of is if maybe the m3 piece is defective. Anyone have any ideas.
I had the same problem with an M3 last year, I'd say you need to change the battery, fixed mine straight away, but I don't have much knowledge in that area.
After allot of trial and error I have found the answer. I did not format my Kingston micro sd card right. Now everything works just as good as before
