You will need a decrypted version of the EBOOT.BIN file and PRAM.SFO from the 1.02 debug update. Message me if you require a link to the file.

Step One:

Download the files and go to where you put your game and edit your pram.sfo to say 3.40 with PS3SFOEdit

Step Two

Update the game to 1.02 using the retail update for your region.

Step 4

go to

now if you have the BLES01032 version just use the SFO.PRAM file and place it in that directory overwriting the old one.

if you have another version of the game use PS3SFOEdit to edit your sfo to say 3.40 in advanced edit. SAVE IT then replace it.
