Hey, I made Pandora's Battery a while back and i told one of my friends that I will downgrade his PSP. That being said, I have a few Questions.... 1.) Will trying to downgrade my PSP (currently 3.80 M33-4)with pandora's battery cause any problems? 2.) Will using MY formatted battery and MY magic mem stick cause any damage to HIS PSP? 3.) Up to what firmware does Pandora's Battery work on? 4.) What will happen if magic mem stick and battery are in my psp with CFW 3.80, will it just downgrade it like a non-CFW PSP? Lol, sorry for the questions, just taking some extra precautions while doing this considering it isnt my PSP that is being downgraded, I wouldnt miind testing it on my own before anything is done to his. Please reply ASAP, Thanks in advance, Coolguy14.
