I would like to update to the latest CFW. I really can't afford to mess this up. I'm on 4.31 currently. I think it was Rogero custom firmware, but for some reason my system information doesn't tell me what custom version I'm on. Also not sure if I need Rex or D-Rex. (Downloaded REBUG_4.46.1_REX_PS3UPDAT.PUP)
Can anyone please explain to me what to do, or point me in the right direction of a tutorial.
