So a few days ago I purchased the piano black psp-2001 core system, I gave it to my friend to use pandoras battery but he told me that it wouldn't work on my psp, I have 5.02 sony firmware but i don't think that has anything to do with it, any ideas? he says that it might be that my psp has a different cpu board or something, any ideas on how to fix it? or will it be possible in the near future? thx :cool:
