Hi I've just started hacking my PS3 and I've run into a little bit of an issue I'll start by explaining how I went about my jailbreak I read about and googled allot and the entire time I documented what I was doing to write my own tutorial to try out when I got home, below is a copy of the tutorial I made and all was going well until I needed to install geohot's jailbreak when I get the error "The Data is corrupt" now I googled this and there doesn't seem to be allot on the subject of this error one conclusion I have come to is that this hack only works on Slim PS3's maybe? I don't know but please read through my guide and point out any mistakes I may have made if any, for now I'm back on OFW 3.55. 60GB PS3 PHAT STEP:1 Have a newly formatted USB drive at the ready then make the following folder structure in the USB... /PS3/UPDATE/ Place the official un-patched PS3 firmware in the update folder on the USB. Then start your system in recovery mode by following these instructions at http://community.us.playstation.com/message/2252774 Place the USB drive into your PS3 and select update firmware, once finished move to STEP2. STEP2 REMOVE the UPDATE.PUP from "/PS3/UPDATE/" on you USB Back to your PC you now need to go to PS3Toolkit/3.55-Peek-n-Poke_Patcher/CFWPatcher Run CFWPatcher and select “execute” Place the new UPDATE.PUP file into "PS3/UPDATE/" now flash to the PS3, same as STEP1, once complete move to STEP3. STEP3 Once this is complete you need to go to PS3Toolkit/jailbreak/ you need to flash this update to your PS3 the same way as step one and two but make sure you remove the old update.pup file form "/PS3/UPDATE/" on your USB drive PS PS3Toolkit is a folder I made to store all of my hacking files not something I downloaded. Thank you!
