I have a PS3 Slim 320 GB with move and 4.31 firmware on it I want to play backup games on my PS3, so what I need to do ? I have downloaded PS3 CFW 4.31.1 by SGK is under development version but it is a ". pup" file how can I install please anybody tell me step by step I am new to this CFW thing.
Also if you are new to all this it is not recommended to install something still in development, so assuming you take the advice from the link above you should then look into ErmaC, Rebug, or Rogero CFW which are more stable than the SGK development versions.
