Where can I find a PSP Downgrader { v3.03 to v1.5 }?

Question

I know the psp downgrader 3.03 is the easiest one to find, but everyone i find requires Grand Thef Auto Liberty Cities (GTA) or requires me to pay for by online credit. And please no links towards .rar files, .rar doesnt work on my computer for some reason.

Answer 1

sorry but to get from 3.03 to 1.5 u need the unpatched gta . no otherway whatsoever, or u can update to 3.50 yet again you will need a umd, but this time u need unpatched lumines, no other what soever or u can update  to any other firmware above this and use the pandora battery to downgrade which would cost u even more unless u do it the lumines or the gta way. so my advice buy the unpatched gta!!!
