hey guys i haven't used my psp in a really long time... so my problem is that the last time i used my psp is when the 3.10 oe-a custom firmware was out. i want to go to the new m33 custom firmware. can i just use pandora to do it? if so, how would i do it? i don't know how to downgrade my 3.10 oe-a back to 1.50 either so if anyone can help me so that i can use the new m33 custom firmware that would be great! thanks in advance.
