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 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 »

I have followed EVERY step. I am trying to downgrade from Rogero 4.46 CFW to Official 3.55 OFW. My PS3 has frozen at 72%. Please reply 🙂

James
Guest

Thanks for your reply, I am sure that my HDD is fully functional and in good condition. I have checked my HDD for any bad sectors and everything is working properly. I have re-downloaded all the files you have provided to reattempt to downgrade again, but it is still freezing at around 70% – 77%. I am making sure that my Playstation 3 is cool while in the process of downgrading to prevent it from overheating. Have you got any more suggestions? Cheers 🙂

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)
