Below are the changes, roughly translated from LizZo to quote: Release - Custom Firmware FERROX 4.81 v1.02 COBRA 7.5

We return once again with a new release for the PS3 scene! Tonight it was the turn of the new 2.1 version of the Custom Firmware 4.81 FERROX.

The new release has been produced with the 'intent to offer a CFW as clean as possible, for that section of users who want to play online with a little more tranquility. But do not worry, the other slices of users will settle! ;)

This new 1.2 version of the custom firmware developed by Developer Alexander leads the addition of COBRA Patch 7.50. As I said, despite the COBRA functions, the FERROX is considered the cleanest CFW. It indicates particularly made for the use Online.

It also thanks the developer Habib for his valuable advice on porting 7.5. I think now you anyway know all the CFW of Cybermodding home, so let's do the rest.

  • COBRA updated to version 7.5 Patch
  • Built on the basis of 'OFW 4.81 SONY.
  • PSN / SEN Enabled.
  • Update from any possibility of CFW (CEX).
  • Ability to Upgrade from OFW 3.55.

  • Download the CFW at the top. Rename the File .pup exactly: PS3UPDAT.PUP and confirm the MD5 with what you find at the top! You can use the Tool md5sums.
  • Take a USB FAT32 formatted, and create a new folder called PS3, inside this create another other still called UPDATE, and inside latter' inseriteci the PS3UPDAT.PUP File, which would be the custom firmware.
  • Insert the USB in the far right of the PS3 port.
  • Be sure to: Remove any disc from the player PS3, Remove any games loaded with any Manager, Disable Internet Connection.
  • Ok. You can choose to install the CFW from the XMB or from Recovery.
  • On the XMB will just go into 'Settings' column, then 'System Upgrade' and choose 'With storage media'. Select the CFW and will start the process.
  • To enter Recovery Instead, turn off the console. Turn it back on by holding down the Power button until the console is turned off again. Now turn it back on by holding down the Power button until you hear two beeps very close. Then release the Power button! Recovery time from the menu, select 'System Update' and follow the instructions.
  • For a clean installation, you can install 2 times the CFW. You can also go back into Recovery and click Options for Rebuilding the Database and Restore the System File. So you'll have a setup more than clean and safe.
  • CECHG04 - Tested and working
  • CECH2504A - Tested and working
  • Two CECH2104A - Tested and working
We tested every aspect, ISO PS3, PS2, PSX, PSP HDD, FAT32 and NTFS, PSP Minis and Remaster, PSN and Game Online, all COBRA functions, in short, we say a little of everything. If you find oddities let us know !!! Do not be shy :)

The new version 1.02 of the Custom Firmware FERROX thus brings the 'addition of COBRA Patch. However, we consider non-essential update if you are previous version 1.01+. The changes are not many in the new COBRA functions, and can not be of interest to most users. You choose what to do. :)

As always, we thank our dear friend and developer @Alexander for his continuous work!

If you have questions or concerns please let us know! We are always available for questions and clarifications, please feel free to ask! :giggle:

I need help with mine, I did all the steps and it shows nothing on that flash drive.
Make sure your flash drive is FAT32. Oh yeah... Make sure you back up your stuff from the flash drive before do this because it will erase it and format to FAT32 and your stuff will be lost.
  1. Right click [Computer] then click [Manage.]
  2. Click [Disk Management]
  3. Choose your USB Drive, right click the mouse and choose [Format].
  4. Click [OK].
  5. You can find the format is FAT32.
  6. And put stuff in FAT32 and try again.
