  2. Disable Automatic Update and Display What’s New:
    • Go to “Settings” > “System Settings” and turn off automatic updates and the display of what’s new.

Installing CFW for Firmware 3.55 or Lower

    • Create a folder named “PS3” on the root of the USB drive.
    • Inside the “PS3” folder, create another folder named “UPDATE”.
    • Place the CFW file inside the “UPDATE” folder and rename it to “PS3UPDAT.PUP”.
  2. Install CFW:
    • Plug the USB drive into your PS3.
    • Navigate to “Settings” > “System Update” > “Update via Storage Media”.
    • Follow the on-screen instructions to complete the installation.

Installing CFW for Firmware 3.56 or Higher (OFW to CFW)

    • Prepare your USB drive as mentioned above and place the HFW file in the “UPDATE” folder, naming it “PS3UPDAT.PUP”.
    • Plug the USB drive into your PS3 and go to “Settings” > “System Update” > “Update via Storage Media”.
    • Follow the on-screen instructions to install HFW.
  2. Apply Patches Using an Internet-Hosted Exploit:

    • Reboot your PS3 once the patch is applied successfully.

FAQs

How can I find my PS3 model number?

You can locate your PS3 model number on the barcode sticker at the back of your console. Look for an 11-digit serial number starting with CECH-XXXX.

My PS3 says CFW compatible PS3: ❌. What should I do?

If your PS3 is incompatible with CFW, do not proceed with the CFW steps. Use the HAN installer instead.

Do I need to install HFW before applying bgtoolset patches?

Yes, we highly recommend installing HFW to avoid the risk of bricking your system.

I’ve installed HFW (PS3HEN) on my PS3. Can I still follow this process?

Yes, as long as your system is compatible with CFW. Ensure you verify your PS3 model number against the CFW-compatible list.

What if I prefer to use PS3HEN?

You also have the option to install PS3HEN for running game backups and some homebrew. However, since all FAT models can use CFW, PS3HEN is not typically necessary.

By following this guide, you can successfully jailbreak your PS3 FAT model on firmware 4.91. Enjoy the enhanced features and flexibility that come with custom firmware!
