I am new to this and downgraded my son's ta-082 v 2.71 to 1.5 successfully. however, I accidently selected the 2.60 updater and now I have v 2.60. How can I restore back to 1.50 or 2.71 to start over? Can I downgrade 2.60 to 1.5 even though I have ta-082. Can I upgrade to an even better version? Dev hook files were corrupted and I formatted my memory stick. what can i do? Somebody please help me. this is my son's PSP and he is going to be pissed if I brick it. I have v 2.60 on a ta-082 board.
