Before I unbricked My psp, it read UMDS. For a while, I stopped using UMD method and just used ISOS, and before I bricked my psp i tried a friends UMD and my psp would just try to read it and make wierd noises. eventaully if you leave it with the umd after about 30 minutes or 20 minutes it would say "the disk cannot be read" Same thing after I used pandora. I tried cleaning lens with a ear swab with alchohal but nothing happened. The laser is still working as I see it since its red. any ideas?
