I have been trying all day to jailbreak my PS3 via USB which is in FAT32 format with no luck. I created a folder in the USB called 'PS3' inside the PS3 folder I created another folder named 'UPDATE' which has my UPDAT.PUP file. I've tried several UPDAT.PUP files from different sources with no luck at all. When I go to System Update - Update via Storage Media I get an error message 'no applicable update data was found'. The USB is showing up on the Playstation under the photo \ music etc. So the Ps3 is regestering the USB. Any help would be greatly appreciated!!
