and press the link that
says "6.39 PSP 1000,2000,3000" and it will download a file called "EBOOT.PBP" open the folder
called "UPDATE" and delete anything that is in there and drag the EBOOT.PBP file you installed.

now, go back to your psp and go to the games (where you start you games) and go down to memory
stick and press it and there should be a downgrader thing in there. start it and do what it tells
