I recently made a PSN account, but I soon figured out I couldn't sign into my account with CFW 5.50 GEN-D3. I was told to downgrade to M33. The problem is, I'm not sure how. I didn't put in the CFW, I had a friend do that. So, I got an 8GB Stick (With my games), and the 32MB stick that came with the PSP. Is that enough to downgrade, then upgrade? Also, I was told it'd be easier with a Pandora Battery, but I'm not sure if I have one. I can access the Recovery menu by holding R, if that's what it does. Any help is appreciated.
