Ok, so I got 2 PSP's, one is mine and one is my brothers. His one was still on ver1.50 so updated to 3.71 M33 no problem. Mine was on ver 2.80, followed some instructions and bricked my PSP YAY!!!. Next mission was to make Pandoras Battery. Purchased another PSP original battery and did the deed with the old one. Made the Pandora mem stick and successfully downgraded and then upgraded my PSP. Now I feel untouchable. I tell my cousin, no probs, I'll downgrade yours and sort it. He has FW ver 3.11. I don't have Lumines and and formatted and remade my PSP pandora mem stick a thousand times and all I get is a blank screen when the mem stick with pandoras (modded) battery is in. With a normal battery it boots up normally. What the hell am I doing wrong. PS all the PSP's are Phatty's. Thanks in advance for any help you guys can give me, been at this for 3 days straight now and I'm losing my mind, kids have forgotten what I look like and I'm sure the wife's now having an affair.
Well if it isn't booting, then the files are not properly on the Mem stick.
Heres what you should do. Download both of these files and extract them.
