I have a bricked phat psp and have tried everything to fix it. I bought a pandora battery, and it works. It turns the PSP on and all that. I have a 4gb sony mem stick, was told it wont work, so bought a Lexar 512 stick to use. I have tried turning it into a MMS multiple ways, from the default cmd way, to the easyinstaller. No matter what when I put the MS in and put in the pandora battery I get all SOLID lights, and no screen. I have pressed x to no avail.
What can I do?
