Hey all. I having a little troubling installing a CFW from 3.55 OFW. I was at 3.15 and upgraded to 3.55 OFW and now am trying to get the latest rebug and cannot for the life of me get my playstation to recognize it. I tried reformatting the flash drive and installing from menu and recovery. Anything else I should try? Also, I am a casual gamer and would like to use some casual mods and such online, is rebug REX the CFW for me?
