since you have the pandora battery you don't need to downgrade just use psp pandora deluxe or another mms maker, and put custom firmwares 3.90 and 5.00 on it; links are in my signature

just a thought he'd been doing them before the psp 2000 came out is downgrading to 1.50 OFW an old way of doing it?
