  **************HOW TO INSTALL***************​
  Your ps3 must be jailbroken or must have just been flashed with a hardware flasher to install cfw.
  
  Make sure your usb is formatted to fat 32.
  
  1. Create a folder on your usb called PS3. (in capitals)
  2. Inside the PS3 folder make another folder called UPDATE. (in capitals)
  3. Put the PS3UPDAT.PUP file inside the UPDATE folder.
  4. Put your usb into your ps3 and go to the settings column, go to system update and update via storage media.​
  
  
  **************GOING ONLINE***************​
  
  On Standard CEX CFW's
  
  1. start ps3.
  2. Use any homebrew apps your gonna use like multiman.
  3. load game to xmb or put disc in.
  4. Open psn patch and disable cfw system calls. (psn patch does the same job as ps ninja, deletes history at exit)
  5. start game and/or sign in.​
  
  Don't hate cuz I've been on psn with cfw for 5 years and never been console banned, up to you how you want to do it. If you have problem loading a game from hard drive, open multiman, highlight the game and press triangle for options, select bd mirror and internal options then select permissions, then press x on the game to load it to xmb (must have a game disc in).
