I got a PSP a couple weeks ago, downgraded then installed 3.10 OE. Everything was working fine as far as playing UMD games as well as games from the memory stick (somtimes I would have to enable or disable the NO UMD option in the recovery console). I downloaded some ISO files and most of them I got to work some of them the screen just went black when I loaded and I had to just shut it off to get back to the main screen. Today I went to play a UMD game. I put the UMD in close the door and nothing. No spinning, the UMD icon does not show up nothing. It is as if I didn't put anything in the drive at all. I have tried multiple games. I don't know what to do. If someone has any ideas on how to fix or what is causing this it would be much appreciated. THANKS!
