You see, I've been trying to upgrade my PSP 2004 5.50 Prome-4 to 6.35 PRO.
So, I download them materials required. After downloading, I put the files to where it's supposed to be. This is where my problem starts. Whenever I start the 6.35 OFW, it says "No Need to Update, Version is Already 9.90" or whatever. I have no clue what to do after that.
Please help me, I would love to play PSX games on mah PSP without crashing.
