ok let me explain myself clearly. When i on my PSP with my UMD in it, it hangs. When i on my psp without my UMD it manage to load perfectly. But when i put my UMD in after it loads, either it hangs or it says UNABLE TO READ DISC. so thats the 1st problem. Can i have some help? The next problem is when i tried to put my psp to sleep, the indicator light blinks rapidly and then it went off instead of sleep. So any kind souls to give me an advice. Oh anyway im using a 3.03oea but i recovered it to 1.5. The next problem is my psp now not only have the problems i just mentioned before and now i cant install 3.03oec.. it says "opening and checking 150.pbp" and then "Unable to open 150. pbp" any take on this?
