1. Go to REBUGs site (click the word REBUG in my signature

) and download 4.80 REBUG REX firmware
2. Make a folder on your USB that's been formatted to FAT32 called PS3
3. inside that make another folder called UPDATE
4. Put it in there then rename it PS3UPDAT.PUP.
5. Make sure to turn the Internet on your PS3 OFF and remove any discs from inside your PS3 then go to System Update and select your USB then let it do it's thing and you'll be on 4.80
Although until CCAPI is updated to work on 4.80 i suggest either 4.75 or 4.78 but it's your call
