Ok, so to downgrade i made a magic memory stick to instal the 5.00CFW. Then used my Pandora battery to get to service mode. ext i installed the 5.00OFW option instead and that sorted it. Thanks everyone that helped

would have been easier to just follow http://forums.dashhacks.com/f133/ult...o-cfw-t299905/ saw this thread late so couldn't link earlier.

as has been mentioned before(incase you've not seen other threads where its been posted) pandora battery+mms is not needed for 'hacking' psp 1000 and non ta-88v3 motherboard psp 2000, its only needed if you end up with a full brick or if/when sony releases a new ofw(at least till a new 'hack' is released).
