This CFW is only for PS3 Models up to 2,5k. Newer Slim Models and Super Slim are NOT Supported! And of course, you will need to have a CFW already installed or be on 3.55 to install this CFW!
Installation method is the same as any other CFW/MFW/OFW.
Just make a Folder called PS3 on the root of your USB and in that folder make a folder called UPDATE. Just copy the HABIB_478_CB730.PS3UPDAT.PUP in there and rename it to PS3UPDAT.PUP. Then just plug your USB into your PS3 and update via USB.
You can download the CFW here.
