Im willing to trade my current psp ( no flaws) for an older psp with the old firmware1.5 or 2.0 ( preferbly the 1.5). I will also put cash into the transaction.
I have a PSP with 2.01 i believe. I'll check tommorrow morning, its over at my gf's place, ill be interested to trade if u want.
Let me just say this, that you can modchip a 2.0 version but not the newer ones. I am guessing that is your reason for switching.
Why don't you just take the firmwire back to 1.5? i know my friend has there are quite are few tutorials i believe.
