As I posted earlier, I already run Chilly Willy's Key Cleaner. Actually, the key cleaner found my psp's key 0x0047 bad or missing. It's already fixed. And I thought, it would sort out my UMD drive issues. Any idea what the key 0x0047 issue/s if not related to the UMD drive?

I also managed to go back to 1.50 fw using DAX firmware flasher. And I updated back to 3.52 M33-2, even without any customization done, the drive still won't run any UMD game or movie. The drive just keeps running, "unable" to read the inserted UMD. Damn, hope this can still be fixed and not really hardware thing.
