DOWNGRADING, Everything was going fine, I was doing everything right then, all the sudden, the power in the hole house went off, Here was another problem, the battery was completely dead and my psp turned off, so now when i tryed to power it back on, the green power light is the only one that turns on. My PSP is history now. I alredy called sony and they said they would replace it for free but I need to have the receip. But I don't have it and if I wanted it to replaced 4 another psp without the original receip they would charge me $125. dollars wich I don't have. I'm so sad. I got my PSP as a birthday present. I don't blame anyone because the downgrade is a perfect job they've created and its not their fault as it could have also happened to me if i was upgrading it.
