I need some serious help. I had used an earlier version of psp set to change my firmware to 1.52. I just recently purchased GTA and i used psp set v.09 to go back to 1.5 so i could upgrade to 2.0. When i went to upgrade using the upgrade on the GTA game i just got the upgrade menus with no words. i could scroll through but not start the update. My psp has serious problems, please help.
