you need to use the pandoras battery to downgrade to 1.5 then you can upgrade to the M33 3.52.

M33 3.52 will let you run homebrew and you can load psp iso's from your memorystick

you need windows xp it will not work on vista

no the only way to downgrade any psp over 3.50 is with a pandoras battery and jigkick mem stick and to make those you need either a original 1.50 psp or a custom firmware psp.

there are a few sites out there that have lists of their members who will do it for you for free but i wouldn't be allowed to post them here.
