I have used the cfw before and I have a 60% knowledge of CFW. My minvercheck return 2.56 or later. I can probably install CFW but I have never used the new ps3xploit flasher and dumper tools (I'm on 4.84 ofw , I have used the great HAN and HEN before). I am afraid of doing/installing it/cfw because I could end up in brick as @pinky said. After installing CFW , I would like to sell fat ps3 and then I will buy the Slim ps3.
