Gaming downgrading psp 3000 ofw

[hellfire12]

is there any way to downgrade a psp-3002 with 6.31 ofw to 6.20?
As i read on coldbirds forum that a psp 3k cannot be downgraded from 6.35 because of the way sony changed the firmware.
Thanks guys

NO.

Several devlopers have been "working" on a downgrader, and some have "successfully" done it.
But nothing has been released yet.

DO NOT try, if you fuck up you will end up with a brick, yo.
