Model: CECHE-01 (Fat 80GB) 2 years ago I migrated to CFW from OFW 3.15 I was told I should be fine with CEX. I'm trying to remember what the difference between multiman and rebug are, and how the heck to update to latest versions, etc. I see on the rebug.me site that D-REX and REX cobra 7.1 look like the latest version. REX seems to be what I'd want to install on my CEX system. Am I just putting this .pkg on a usb stick and updating? This seems like something simple to do, I just want to make sure I'm not going to brick.
