Hey, I am purchasing a new ps3 slim (cech-2501b) running 3.40 OFW and plan on installing the latest CFW ("Rebug 4.76.1-LITE– Cobra 7.1 – Toolbox 2.02.07"). It was my understanding that you first install OFW update 3.55 THEN whatever CFW you like. I was told in another post, however, that for Rebug 4.76.1-LITE– Cobra 7.1 – Toolbox 2.02.07 you do not need to install the OFW 3.55 beforehand. They said just install Rebug onto the existing factory OFW 3.40. Is this correct? And... does anyone have a link to an "updated" or appropriate guide for installing Rebug? Many of the guides are now outdated and I really would rather not lose the $300 I just spent bricking a new ps3. Any insight into this would be greatly appreciated, thank you.
