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.
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.
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 – !!!
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.
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

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.
Yea good
Restore ps3 system in recovery….enable system update debug….update usb….had the corrupt error but this worked!!thanks
Files are corrupt
when does your ps3 say they are corrupt? the files are still fine so you must do something wrong. can you tell me what step failed?
BTW, this guide only works on jailbroken ps3’s with already custom firmware installed… it won’t work on official ps3 firmwares.
so this doesnt work on sony original ps3 right? i am on ps3 slim 4.80 and i have been in front of my pc for months trying to find out a way of jailbreaking it without a e3 flasher or any other flasher. guess my time was useless
you can look it up in the table but probably not
if it gives that error use another usb stick formatted in FAT32.
worked for me!
my ps3 shows an error 8002F957 🙁
does the error occur on the QA flag application or the update?
When it installs!
the update file or the QA-Flag application? information please
wont install the second CFW, it says its already up to date and doesnt require to be updated, can I install any other cfw besides that one?
did you do the QA-flag step? doing this step wrong can prevent the update
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!!!
Thanks gan…work 100%
THANK YOU YANKO
it worked it said the same thing as pyours but then did what you did andit works thank you and the person who made this article
LETS PLAY online some time BlitzCometJB
Thanks you
Must do these 2 steps as yanko mention:
1. Under debug setting went to system debug update and switch it ON.
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.
if its already on 3.55 you can just install the cfw without using the downgrader. try to download one of the latest custom firmwares and try installing it from xmb or recovery and see if that works
Which one would you recommend I try? Im barely getting back into jailbreaking/modding after 2-3 years. sorry for all these noob questions lol. All im trying to do is basically get online and hack/mess around on GTA.
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)
you could try inserting a empty hdd and reinstall the firmware on the empty drive.
not wor at wall
error (8002f957)
Da same for me did u fine solution at ist step its says error 8002f957 pls help wat should I do
what’s your current firmware version? did you eject your cd before installing the downgrader?
when i put the downgrade 3.55 it says update data of version 3.65 or later can be installed on this system please help
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 willing to do whatever at this point. Is there any way to roll back this update without jailbreaking? And if not, what would I need to do to my system to make your rollback work?
Thanks!
error (8002f957) when install the downgrade 🙁
same here error (8002f957) I have both ps3 Fat and a slim one. SLIM one already jailbroken but the fat one my brother accidently updated to 4.60 ofw.
thanks my ps3 is bricked
you’re welcome. you probably didn’t read every step like most of the people that are complaining.
hey can i fix this error 800 something like other comments i cant fix it help im on 4.60 and i was trying to downgrade
are you on 4.60 official firmware? this guide only works with already “hacked” playstations, there is no way this will ever work on original sony firmware
file corrupted when trying to install downgrader
What is the firmware you are trying to downgrade?
I tried updating with the downgrader and it gives me the same error message. I followed the directions as well. I’ve tried countless websites for 7 hours straight today and with all of them im getting the same error (8002F957). I have a ps3 slim and its already been jailbroken but my friend updated by mistake last night so im really trying to see if i can fix it! Not complaining just depserate for some help.
well you can’t downgrade your ps3 if your friend installed an official firmware. you will need to downgrade with a flasher.
And how do you do that?
First you will have to buy a E3 NOR Flasher (+- $50) … Here is my guide on installing the E3 NOR Flasher in a PS3 Slim : http://stevenbreuls.com/2014/02/installing-e3-nor-flasher-in-ps3-slim/
I don’t have a guide on the downgrade process but guides on downgrading can be found elsewhere…
!!!THIS IS THE SOLUTION!!!
Thank you very much! First i got files corrupt but this workaround did it.
thanks a lot !!
it says its already up to date and doesnt require to be updated. i can’t instal 3.55 CFW
did you enable the QA-Flag? => are there 3 new icons in the settings tab?
Hi,
When I unzip the 3.55 firmware and put it into the folder, it is still in firefox ?? Do you know what I mean ?!!
Not sure what you mean, i’m using chrome… the zip should be extracted anywhere on your pc, this has nothing to do with firefox?
Thank you for reply Steven !!
I put unzipped file into new folder UPDATE ( PS3 ) , but when I try to open it on my PC , nothing happens ??? Is this meant to happen or should I be able to see whats on the file ??
Or is this file only readable on PS3 ??!!
your PC cannot open PUP (playstation update) files. only your ps3 can read these files
Feel really stupid after asking that !!! Thanks so much for replies Steven
no problem
