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.

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!

First Download the Rogero 3.55 Downgrader (Here), copy the file on your USB stick in the UPDATE folder like the image below :
Now plug the USB stick in your PS3, navigate to Settings->System Update and choose to update from “Storage Media” :
Now verify that the version is ‘3.55 Rogero – Downgrader”, then hit X
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:
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.
[su_spoiler title=”Set QA-Flag” style=”fancy”]
Download the QA-flag files (Download Here), copy the .pkg file on your USB stick and install the software on your 3.55 PS3:
Now start the QA-enabler:
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:
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.
Your QA-flag is enabled!
!!! – Only continue if your QA-Flag is enabled – !!!
[su_spoiler title=”Install 3.55 CFW” style=”fancy”]
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.
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 :
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.
[su_spoiler title=”Optional – Install other CFW” style=”fancy”]
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)
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
