I have the thumb drive with Rebug set up in a FAT32 Thumb Drive as PS3 -> UPDATE -> PS3UPDAT.PUP The PS3 says "Applicable Update Data Not Found" when I try to update from storage media. I used this same thumb drive to downgrade and install 3.55? WHAT DO? >_< Is Rebug 4.8 only supposed to be 55MB? Because that is how big the PUP file was when I downloaded it.
