Hello, I'm new to the PS3 hacking community, and I just got a PS3 Slim (model CECH-3004B) yesterday, and it was on 4.46. Any CFW I tried to install with a USB just threw me up an error saying the data is corrupted, and I tried to update to 4.80 and install the Rebug 4.80.1 CFW, but it will still give me that error. Please is there a way to hack my PS3 on 4.80 with a USB without 4.7X or something? I really don't want to buy another PS3
