Here's a webMAN_MOD_1.47.09_Updater.pkg that supports PS4 4.84 CFW, and from Bobby_Downgrades on the PS3 4.84 OVERFLOW CFW Collection notes:

Here are the links for the read me files for each version. Each read me is also included inside each download:
Lastly, some notes:
  • Standard = a normal version of CFW
  • Cobra = a CFW that runs the Cobra payload
  • No BD = can be installed onto a PS3 with no Blu-ray drive and still functions as normal (minus discs)
  • No BT = can be installed onto a PS3 with broken Bluetooth/Wifi module (bypasses install of Bluetooth FW)
Please always read the READ ME.txt files inside download. I have not included Webman inside the CFW as too many people complained.

I have tested all CFW versions and am certain there will be no problems but as always with CFW you install at your own risk.

When I have more time I will update toolbox and spoofers for overflow CFW and I have a couple of new things planned, will get to that when I can find the time, as always thank you to the people who support the overflow brand.

If you just want to spoof your FW version have a look out for ZoFmodz, he has been releasing spoofers since 4.55 and has consistently been the first person to release. He stopped releasing a few fw versions ago due to people taking his work but I have persuaded him to release again. So if you don't want to update CFW and just want to spoof check him out.

:arrow: Finally, below is another PS3 4.84 Dualboot Firmware from littlebalup with details as follows to quote:

Download: (196.37 MB)
  • Made out from OFW 4.84.
  • Patched isoldr and spu_pkg_rvk_verifier to disable ecdsa protections allowing to install CFW 4.84 and above over it.
  • Core OS patched files have the exact same size than the OFW.
  • Core OS file table is exactly the same than the OFW.
  • PUP size is exactly the same than the OFW.
More stealth than it, its an OFW ;)

Tested on both NAND (CECHC04) and NOR (CECH-2004B).

2. Inside the PS3 folder make another folder called UPDATE. (in capitals)
3. Put the PS3UPDAT.PUP file inside the UPDATE folder.
4. Put your USB into your PS3 and go to the settings column, go to system update and update via storage media.

:alert: According to Cerial_iQ, roughly translated: Although it seems that the good Bobby_Downgrades use a lot of the code without revising of its versions 4.84, since again this CFW returns to have the same error in the PSP emulator of its version 4.84, which makes any game or application that use the PSP emulator does not work. I even dare to say that I probably also inherit the problem of PS2 games on retro consoles, although I don't have one on hand to secure it.

Hello everyone,

Need a bit of advice as I am trying to figure out how to downgrade from 4.55 OFW on ps3 fat model CECHA01. I've tried everything! Lately it's been hard to find the right files without misleading information. Can someone please help? Ugh!!

Sorry I am 4.55 OFW and I want to downgrade to 3.55 OFW. Does anyone have a link or short tutorial? Thanks!

Its time to play with my ps3

Thanks for the hard work and not sitting on exploits/cfw and shares with the community some ps4 dev can learn from


So i installed this on my phat ps3 60gb model pal version, and everything works great except playing any ps2 original disc just gets me blackscreen, and then i have to hold the power button to turn off the console any solutions?
