Ok, I installed the 4.84 hfw and flashed the pse3. Now I have to install rebug tool 4.84 and following the guides on the internet I should first download an update files of rebug. The I have to rename it on PS3UPDATE.PUP and moving into the usb (usbroot/PS3/UPDATE/PS3UPDATE.PUP). I followed everything step by step but once I go on "update system via usb", when the updating reach around 65% a message appear saying "files damaged". I tryied many times but I am not able to update rebug. What can I do? Is that maybe because I already have an older version of rebug already installed on the ps3?
