I've had this problem for a long time. It's a strange problem and I don't expect that I will get any answers. This problem comes and goes. Half the time when I start up the PSP, it does not recognize that there is a UMD in the tray. UMD drive doesn't seem to try to read it. If I start an ISO, hombrew, or a PSN game, the system will freeze at the gameboot. It is the default gameboot, I did not modify it. Sometimes when I start up the PSP, the UMD drive starts up and it does display the UMD in the XMB. In that case, everything works fine. Also, if I pull out the battery during a game, rather than shutting it down normally, there is a higher chance that it will start up fine. I have tried reinstalling CFW and restoring the IPL keys. Nothing seems to work.
I'm not sure if this is a hardware problem or a flash problem. The UMD drive can read disc fine when it works. Even if the drive was broken it shouldn't freeze the system when I boot homebrew. Has anyone ever experienced this?
