  • Download the CFW at the top of the page. Rename the .PUP file exactly in: PS3UPDAT.PUP and compare the MD5 with the one you find at the top of the page! You can use the MD5sums Tool that you find online.
  • Take a USB formatted in FAT32, and create a new folder called PS3, inside it create another one called UPDATE, and inside this last insert the PS3UPDAT.PUP File, which would be the Custom Firmware.
  • Insert the USB into the rightmost port on the PS3.
  • Be sure to : Remove any disc from the PS3 player, unmount any games loaded with any Manager, disable Internet connection.

From XMB

  • Simply go to the ‘Settings’ column, then ‘System Update’ and choose ‘By storage media’.
  • Select the CFW and the process will start.

From Recovery

Enter Recovery:

  • Turn off the Console.
  • Switch on again by holding down the Power button until the console turns off again.
  • Now switch on again by holding down the Power button until you hear 2 Beeps close to each other.
  • At that point release the Power button!

In Recovery:

  • From the Recovery Menu now, select ‘System Update’.
  • Just follow the instructions on the screen, and you’re done!

For a clean installation, you can install the CFW twice. You can also go back to Recovery and choose the Options to Rebuild the Database and Restore the File System. This way you will have a more than clean and safe installation. Ok. You can choose to Install the CFW from the XMB or from Recovery.

As always, the sources of the Alexander developer will soon be available in his Github.
