the answer is the Pandora's battery. you can find it at QJ.NET - QuickJump Home - PlayStation Portable News - PSP Updates. youre gonna need someone with a already downgraded PSP. or i can do it if you also want that UMD drive fixed you can hit me up.

And the only way I'd seen to downgrade the firmware is to use the original Lumines UMD, which, of course, I can't do. If I can't get any function out of it as a unit, is there any chance of being able to use the LCD for future modding? Thanks in advance!
