I have: Silver/Original NDS Phat Firmware v7 M3 Mini SD v1 Trascend 1GB Mini SD I purchased my M3 around June/July. It's been working fine, until somewhere around loader v29 was installed on it. From then on, it would sometimes startup on my DS as a blank black screen, and I'd have to try it again 1-2 times and it would work. I think updated to the latest loader, v30C as well as the latest game manager. After switching to that the day it was released, my M3 had been booting up perfectly, until today. I tried playing MPH which I had not played in awhile, and was patched with GM v2x(20 something), and after done playing against some bots, I left the wireless mode, and shut off my DS. When I rebooted my DS, it showed the warning screen that says it's not an official Nintendo product, then went to a black screen and stayed there. I kept rebooting over and over in NDS mode, same thing, then I tried GBA mode over and over, same thing. At some point it got to where it wouldn't even show the warning screen. I tried it on another non-flashed red DS, it worked the VERY FIRST time, and when i retried, no luck. And since then, no more luck. PLEASE help and give ANY possible explinations for this. Does it appear to be the Mini SD crad or the M3? I don't have another Mini SD card, so I can't try and see if it's the card.
