Firmware Features:

  • Built on the basis OFW 4.55
  • Disabled the coreOs and control ECDSA
  • LV1: patched to remove the protection LV2
  • LV1: Peek & Poke
  • LV2: Peek & Poke
  • LV1: patched coreOs Hash Check (prevents the brick consoles downgraded not dehashed)
  • Compatibility PS2 Games
  • Compatibility PSP Games Remastered
  • Compatibility Games PSP Minis
  • Keys / Key 4.55 (4.55 start games with keys EBOOT / sprx)
  • PSN / SEN Allowed for return online
  • RSOD Screen Bypass for consoles suffering from RSOD
  • PS3 BT Remote Patch
  • PS3 Blu-Ray DISC patch
  • Compatibility with the latest version of the REACTPSN
  • App_home/PS3_GAME
  • Install Package Files
  • Ability to Downgrade from OFW 3:55 with qa activated.
  • Can be installed by Rogero CFW 4.xx (You may want to RECOVERY)
  • Can be installed by Rebug CFW 4.xx (You may want to RECOVERY)
  • Can be installed CFW Habib 4.xx (You may want to RECOVERY)
  • Upgradeable from 4:50 FERROX 1.0 (XMB)
  • Supports InGame XMB ScreenShot Feature
  • Supports Remote Play Feature
  • Stability as nell'OFW 4:55
  • Ability to downgrade from any custom firmware with qa activated.

Console Models TESTED:

  • CECHL04 [Working!]

It is recommended that, after a successful installation of custom firmware, run:

  • Settings> [System Settings]> [Restore Default Settings]. (From the XMB)
  • Restore File System (Recovery)
  • Rebuild Database (Recovery)

So, you will have a clean install and you will not have problems. (Thanks to franci97 & SonyForever)


If you want to possibly downgrade from any version of CFW FERROX 4.x to an OFW CFW 3.xx or 4.xx, you have the foresight to have installed the first qaflag and set the DEBUG SYSTEM UPDATE "ON". (For all those who incur 8002F157 error, it means you have not activated the MODE 'ON DEBUG ON qaflag through and then have to do the deashing on the console).

To correct this error: Install CFW 4.21 Rebug or CFW that allows you to activate the qa flag and the modalities' debug. Upgrade to OFW 3.55 for two times in a row. (That's right, to install RECOVERY twice the OFW 3.55. Proceed with the installation of any other CFW's)

I remind you that the starting point of this custom firmware is 3:55 Original Firmware or any custom firwmare.

Special Thanks TO:

If in the event you go to a meeting SoftBricked, you are required to write in this thread, so that I can correct the error. Thank you all.

So I can play online with ferrox dual boot ofw no problem but I've searched the Internet and heard of people getting banned while getting online on black ops2. Will the ferrox dual boot ofw prevent that because it's very similar to an ofw. I've looked online for a while and couldn't find out any info.
