Downgrade any CFW PS3 to 3.55 or any other CFW

Changing to another CFW distribution can be a problem since not all CFW support the latest updates, this guide will help you installing any other CFW version on your PS3 or simply go back to 3.55 where it all started.

Requirements

– PS3 on any CFW
– Downgrade Files (Download Here)
– QA-Flag (Download Here)
– Fat32 USB Stick(512Mb+)

Warnings

Accidental upgraded PS3’s from CFW to Official Firmware CANNOT be downgraded using this method, these can only be downgraded using a flasher.
! – I am not responsible for bricked PS3’s
! – For educational purposes only
Before updating, remove your Game disk, this may cause your ps3 to update to the version that came with the game and make your ps3 unable to downgrade without hardware flasher!

Downgrade

First Download the Rogero 3.55 Downgrader (Here), copy the file on your USB stick in the UPDATE folder like the image below :

ps3pcupdate

Now plug the USB stick in your PS3, navigate to Settings->System Update and choose to update from “Storage Media” :

RogeroDG_UpdateUSB

Now verify that the version is ‘3.55 Rogero – Downgrader”, then hit X

RogeroDowngrade_Title

Your PS3 will now restart and start downgrading the firmware. When done, your PS3 should restart and you should see the Rogero boot logo, to verify you are on 3.55, navigate to “System Settings -> System information”, it should say 3.55:

RogeroDB_3.55

Your PS3 is now downgraded to 3.55, however, this is not a fully functional firmware we will need to convert this 3.55 to any CFW to get back jailbreak functionalities.

Set QA-Flag

Download the QA-flag files (Download Here), copy the .pkg file on your USB stick and install the software on your 3.55 PS3:

RogeroDB_QA-Flag

Now start the QA-enabler:

RogeroDB_QA-Flag

The screen should turn black, your PS3 should beep 2 or 3 times and then go back to the home screen. Now to verify you QA flag is enabled, go to network settings. don’t open the menu but just move the cursor on the icon like below:

RogeroDG_NetworkSettings

Now on your controller press these buttons at the same time :
L1 + L2 + L3 (press left stick) + R1 + R2 + dpad_down and you should see the following menu appearing: if not working, restart your ps3 and try again.

RogeroDG_EddyViewer

Your QA-flag is enabled!

!!! – Only continue if your QA-Flag is enabled – !!!

Install 3.55 CFW

You will not be able to install any CFW yet, the syscon version is 9.99 so we need to fix this with the 3.55 Rogero’s firmware: Copy the file on your USB stick (overwrite the downgrader file) and insert the USB in your PS3, now go to Update and choose to update from Storage Device.

RogeroDG_3.55CFW

Now your ps3 will update and restart to 3.55 Rogero CFW. To check if the firmware installed correctly go to system settings -> system information :

RogeroDG_3.55CFW4.25

the firmware should say 4.25 however the firmware installed is 3.55, the 4.25 is just a version spoof so the firmware runs newer games and eventually can connect to PSn. This is a functional firmware however it is recommended to update to a newer CFW.

Optional - Install other CFW

Download your desired CFW and copy the PS3UPDAT.PUP file on your USB, insert the USB and  navigate to system update -> Update via storage media: (install from recovery if the update fails)

RogeroDG_4.50CFW

Now verify that the version you are installing is correct and make sure it is not an Official Sony Firmware. If you are 100% sure then click ok and your PS3 will restart, update then restart in the chosen firmware. Check your firmware version to confirm your update was successful.

Please, whenever you use this guide successfully, please post your downgraded start and end firmware in a comment below, this will help others confirm their version has been successfully downgraded before:

Ferrox 4.66 -> Ferrox 4.65 – no need to download & install QA-Flag, build in with Ferrox CFW

Thanks ever so much for this tutorial. I never would have been able to downgrade without you. The only issue I faced was that it wouldn’t let me install the 2nd update using System Update option so I had to update via the recovery menu instead. Keep up the good work.

I did, this is what I did to fix it ( just finished it.)

Went to network settings and did the button combo: L1+L2+L3+R1+R2+dpad down

Under debug setting went to system debug update and switch it ON.
Then installed Rogero 3.55 v3.7A CFW in safe/recovery mode.

Finally installed the latest CFW. ( trying the new rogero 4.6 and will try the darknet CEX 4.65 v1.02 tomorrow)

Using the irishman instead of multiman, running games that were not working before, so better for now.

thank you for your help!!!

Must do these 2 steps as yanko mention:
1. Under debug setting went to system debug update and switch it ON.

  1. Then installed Rogero 3.55 v3.7A CFW in safe/recovery mode. —> MUST IN SAFE MODE

How to get into SAFE MODE:

Ray, I just got a Slim 3.55 PS3 that I guess is on DEX Rebug but not running Debug CFW. All That I See Is “Debug Setings” Under “Network Settings” and When Opening Rebug Toolbox It states I’m not running Rebug. The LVL2 Kernel Is (CEX) and The Target Type Is (DEX). When I Try Using The Rogero 3.55 Downgrader It Keeps Bringing Up That The Data Is Corrupted With Error Message (80029CCA). Tried Everything I Could Think Of, Even Updating in Recovery Mode.

Upgraded to 4.75.3 Rebug D-Rex and I believe I accidentally downgraded to 4.75.1 D-Rex but that’s when I got stuck at 99% installation loophole. Can’t even get into recovery mode. Any suggestions? Or am I completely screwed? I read about re-formating the hard drive but they recommend to back up in recovery mode (which I can’t access)

I have an original 60gb backward compatible ps3. The blueray player died and I replaced it. It now plays blue ray movies but not games. I get the 80010017 error. I really believe this is a firmware issue. I have tried almost everything including a full restore – and even though I did not do a system update and it was entirely restored to default settings, the system software showed up as 4.65! I have read that restoring the version to 3.55 can sometimes be a fix for this error. My system has not been jail broken, but I am… Read more »

Thanks for your reply. I have checked my HDD for any bad sectors and everything is working. I am sure that my HDD is fully functional and in good condition. I have re-downloaded all the files you have provided to reattempt to downgrade again however, it is still freezing at 70% – 77%. I am making sure that my Playstation 3 is running cool while it is downgrading (avg. 45^C). Have you got any other suggestions? Cheers 🙂

I have tried to downgrade another CFW PS3 with a NEW 500GB Western Digital Seagate HDD I had replaced last week (I am downgrading this Custom Firmware PS3 for a friend). Using the same method the PS3 still freezes at around 70%. Both console are in Grade A excellent condition. I am downgrading these consoles because the current CFWs are bugged and unstable. Are there any other methods of downgrading custom firmware consoles to 3.55? Thank you for your time.

However i’m still confused why the firmware Randomly stops around between 70% and 77%. what’s your current cfw?

Having the a similar issue: Have done the first update, and enabled QA.

Performing the second update through system menu copies the file to the disk, reboots and tells me the latest version is already. Through recovery it copies the files to disk, reboots and says “The data is corrupted. (8002F157)

Hey, after reading lots of threads and watching videos; I still don’t know what my first step should be. My PS3 (20gb CECHB01) has never been JB (im pretty sure). I upgraded its OFW from 2.76 to 3.55 OFW. Do I need to go through the hoops with the whole QA thing? If so what should be the first CFW to use? If it is not necessary- can I just go straight to the installation of the CFW that I think I want without worrying about any QA stuff? – Sorry for the long winded inquiry but I really don’t… Read more »

Hey Steven. Thanks a lot for replying so soon! I’ve upgraded my HDD to the 250gb i had in my normal PS3 and I decided to get my feet wet with Rebug 3.55 even though I probably coulda just tried the latest build. Now I’m trying to recollect myself and re-find and re-read all the stuff that has to do with Nand export and eID and hopefully successfully create the files before I QA and flash the latest Rebug. If you happen to catch this in time while I’m still not finished (whether that be a brick or a success)… Read more »

That makes sense. Right now I’m running latest Rebug and I’ve successfully run a PS3 and a PS2 Backup initiated by Multiman. But for some reason I can’t figure out how to stream the PS3 ISO that I transfered to my PC with Multiman. Also I think I gotta learn how to FTP correctly with say Filezilla since Multiman seems to limit itself to about 8 megs a second which is really slow for transfering large amounts of data. Any idea if FTP requires the PC to act as a server or can I just run it as a client?… Read more »

Thanks, I appreciate it. Was nice to have a Veteran to the scene advise me. As for your suggestions, I agree with you in terms of best approaches. But right now I’m try to work within my budget; so since I can’t afford to get myself an enclosure right now I wanted to try streaming. I might end up attempting to convert one of my Ethernet cables to a Crossover (hopefully don’t mess it up).
