(UPDATE: Rogero has released an updated downgrader the lets you downgrade to 3.55 from any firmware. I have created a guide and here is the link on my tutorial on how to downgrade to 3.55 from any CFW)
If your PS3 is already running Rogero 4.21 and you want to upgrade to Rogero 4.30 and you are having some trouble updating it to Rogero 4.30, or you just want a “clean” install from 3.55 to Rogero 4.30.
Requirements:
A USB Flash drive (Must be big enough to accommodate the installation files) or an external HD
A PS3 running Rogero 4.21 cfw ( this is also applicable to PS3′s already on Rogero 4.30 cfw)
Downloads:
Download Rogero 3.55 cfw here (Mirror here)
Download Downgrader PUP here (Mirror here)
Download QA Toggle pkg here
Here are the steps to Downgrade to 3.55 from Rogero 4.21
IMPORTANT!
Remove any discs inside your PS3 when performing the update.
1. Download the Downgrader PUP, and rename the file to “PS3UPDAT.PUP”
2. In your USB flash drive or external HD, create a new folder and name it “PS3″
3. Inside the “PS3″ folder, create a new folder and this time name it “UPDATE”
4. Copy the Downgrader PUP (which is now named “PS3UPDAT.PUP”) inside the “UPDATE” folder
5. Insert the USB or external HD on to your PS3 and then go to “System Update” and select “Update Via Storage Media”
6. Follow any onscreen instructions that would come up.
7. Once the update is finished, you will now be on a hybrid CFW3.55, it will still show you have Firmware version 4.21 from system settings (this is normal)
8. Enable QA Toggle flag:
- 8a. Download the QA Toggle pkg
- 8b. Copy the file to the root of your USB or external HD
- 8c. Insert your USB/External HD to your PS3
- 8d. On your PS3, go to “Install package Files” and install the QA Toggle PKG
- 8e. Once installed, run the “Rebug Toggle QA” on your PS3, (The screen will go Black and you will hear 2 or 3 Beeps and when finished it will go back to the PS3′s XMB, and if error comes up, just repeat this step.)
- 8f. Go to “Network Settings” (do not open it) then all at the same time, press the following key combo : L1 + L2 + L3 (press left stick) + R1 + R2 + dpad_down (its hard you might want to get an extra hand for this)
- 8g. If the QA Flag was done correctly, you will see Edy Viewer, Debug Settings, and Install Package Files.
9. Now we can install either an Official Firmware 3.55 ( do not install any OFW higher than 3.55!), or 3.55 Kmeaw or Rogero 3.55. Here we will install Rogero 3.55
10. Download the Rogero 3.55 cfw and rename the file to “PS3UPDAT.PUP”
11. In your USB or External HD, go to PS3 then UPDATE and replace the old “PS3UPDAT.PUP” (downgrader PUP) with the new “PS3UPDAT.PUP” (Rogero 3.55 cfw)
12. Insert the USB or external HD on to your PS3 and then go to “System Update” and select “Update Via Storage Media” (It has been reported that doing this in recovery mode is more successful!)
Here’s How to go to Recovery Mode
12a. While your PS3 is on, turn it off by pressing and holding the power button until it turns off
12b. When the PS3 is OFF, press and hold the power button until you hear two beeps
12c. When this happens, the PS3 should boot up in recovery Mode (if it does not, repeat steps 12a and 12c)
12d. While on recovery mode, select option 6 (System Update)
13. Follow any onscreen instructions that would come up.
14. And your done! You are now on Rogero 3.55 cfw and you can now install Rogero 4.21 cfw or Rogero 4.30 cfw!
(Important note: Run the Rebug Toggle QA again (step #8e to 8g) if you are going to continue and install Rogero 4.21 cfw or Rogero 4.30 cfw!)
So to make it short:
1. Install the downgrader PUP
2. Toggle QA
3. Install Rogero 3.55
4. Toggle QA
5. Install Rogero 4.30 or Rogero 4.21
Read here if you want to learn How to install Rogero 4.30 cfw on your PS3
Also, after updating to the latest Rogero CFW, you would also need to update your Multiman to compliment your updated CFW, here’s the link on How to install Multiman 4.18.0.

“This CFW was tested on most PS3 Models by different testers and no problems were encountered. But as any CFW release you must install it with caution and by following proper instructions, No one will be held responsible for any damage caused.” – Rogero
i follow guide fine i finish step 8g and start 9 but firmwares i try are non recognised or i get this 8002f157 my firmware says 4.21 i can still add .pkgs multiman still works but games dont boot any ides.
Try installing it via recovery mode, also if an error pops up, just press select + start.
after i attempted to downgrade from rogero 4.21 using the downgrader pup the fw says 4.21 i belive it is meant to say that however when i boot the ps3 should it say playstation or rogero mine says playstation it used to say rogero
After downgrading, it’s on a hybrid cfw but not Rogero so it should say only playstation. It’s after you install the Rogero 3.55 should it go back to saying rogero again.
onde encontro “Configurações de Rede” nao queriam era dizer definiçoes de rede?
on the XMB, on the settings section. It’s the most bottom one.
e tanbem nao sei o que quer dizer “dpad_down”
It’s the direction pad. the one on the left
estou no 4.21 nao comsigo voltar para 3.55
Did you follow the steps?
a em algum lugar que eu possa ver um video de como fazer isso??
nao estou a conseguir fazer o passo 8f
nao estou conseguindo fazer o passo 8f
8e repetir paso de nuevo hasta oír 3 pitidos y luego intente de nuevo 8f.
(QA no toggle trabajando un par de veces es normal, según su creador, yo estoy tratando de encontrar el enlace).
Hi I got mine working, i just followed the steps
1. Downgraded from 4.21cfw using Downgrader PUP normally
2. Run Toggle QA
3. Installed Rogero CEX-3.55 CFW (via recovery mode)
4. Run Toggle QA again
5. Installed Rogero 4.30 cfw (via recovery mode)
Thanks!
Hi Ted i think your steps i have done 1 and 2 but now cannot install any more fw
Try installing via recovery mode?
i am still trying my ps3 will detect the downgrade.pup and run to 100% then say corrupted data 8002f157 ive tried other cfw but the say no applicable update was found
Did you run QA Toggle before trying to install it?
Hey thanks for this article, you answered a few of my questions on Yahoo Answers.. I’m on v4.25, can I still use this method for v4.25???
v4.25? I’m guessing you are running Official Firmware, unfortunately you cannot do this for Official firmwares.
i cant update to 3.55 via recovery mode. it just says there is no applicable update data.
did you make sure to put the correct files in the correct folders and with correct file names?
Can i downgrade Rogero 3.40 to 3.55 on above mentioned method. Replay soon….
plz can anyone tell how to downgrade Rogero 4.30 to 3.55. replay soon.
Yes you can do this on Rogero 4.30
im on 4.31 OFW can i do this?
Unfortunately you cannot do this on 4.31 OFW
HI pls help
when i try to install the 3.55 rogero
it tell me that the latest version is installed and no need for this update
What firmware are you on right now?
Hello tech84 hey look I was in 3.55 kmeaw and then I install Rogero 4.30 v2. Via recovery mode do everything went right but the wierd thing is the system information appears 4.31 but when I turn on the ps3 I get the warning message and Rogero ps3 on the screen but I get error message on multiman and I can’t install any pkg.
Well that’s weird, did you have any discs inside the unit when you updated?
And when you boot up your ps3 does it show the Rogero watermark at the start up screen?
Yeah it shows Rogero on the screen and the warning message too
Then it means you have a working Rogero cfw, are you using a firmware spoofer?
THANKS
I followed the steps
and it work fine
Hi Download QA Toggle pkg dosnt longer exist or been removed can you upload it again
Thanks
Thanks for the heads up, the file has been re-uploaded and fixed the link.
I have 4.25, can I do it?
This only works on Rogero 4.21 or 4.30
i want to ask if i must i use QA Toggle.okg and if i not use what will hapen
cannot say, but it is advised to toggle QA first.
I did my first upgrade and did not toggle QA and it worked, but for some people, they say they had errors when they did not toggle QA first.
Hi. Thanks for your effort ! My question is : Can I downgrade from 3.72 using this method ? Thank you.
Unfortunately you cannot, you must be on Rogero 4.21 or 4.30 for this to work
So I should upgrade first … then it will work right ?
Technically you should downgrade back to 3.55. But that requires hardware flashers. You would need someone who has access to those in order to downgrade.
Thank you for your quick replay but still .. can I upgrade to 4.21 or 4.30 than use your method to downgrade ? .. Thanks !
yes it would work if you are able to install Rogero 4.21 or 4.30, but you will not be able to do that with 3.71. You would still need to downgrade your 3.71 first to 3.55 before you are able to install any CFW on it.
I want to downgrade my ps3 from Rogero 4.30 to 3.55 Kmeaw, however just concerned about getting Bricked. Till step 14 I understood everything but what is this rebug? Do I have to rebug once I am successful till step 14 and do not want to upgrade to 4.21 or 4.30. I want to use 3.55 Kmeaw with multiman.
It mean to dehash your PS3 first when you are already on 3.55 before installing any other firmware for a safer install
Basically just to Toggle QA
Thanks Tech84. So what I have understood is: If I am on OFW 3.55 and wants to install any CFW then I need to dehash. Whereas If I am already on 4.30 rogero and wants to downgrade to 3.55 CFW Kmeaw I need not to worry about dehash after step 14.
You would only need to dehash if you are not originally from 3.55 OFW/CFW. Meaning you were from higher Official firmware (3.60, 4.00 etc..) and then downgraded down to 3.55, that’s the only time for a mandatory dehash.
If you downgraded from Rogero 4.30 or 4.21, you would not need to dehash. But you would still need to toggle QA when installing any higher CFW or OFW while you are on 3.55.
You response and help is much appreciated. Thank you very much for looking into my query.
You’re welcome.
Apologies for this stupid question but will I have to flash or dehash after step 14??
You need to Toggle QA first
eu posso instalar o rogero cfw 4.21 em cima do ofw 4.21 travado corre o risco do brick obrigado
hi, first of all, thanks for all the help you bring for us!
I need some help, my PS3 Fat 40gb (oldie) has OFW 4.21, can I try these steps on it to downgrade it to 3.55 for the install Rogero?
Thank you very much
Unfortunately you cannot, you would need a hardware flasher in order to downgrade to 3.55 and then you can be able to install CFW on it.
Thanks a lot for your answer! I almost mess up my ps3 with al the fake info in the web.
Hi..i accidentally updated my ps3 to sony v4.21 can i use these settings to down grade I’m tring to jailbreak my ps3 without “bricking” it also can i ask qhats the easiest way to jailbreak if i can using v4.21
Unfortunately you cannot use this guide to downgrade your 4.21 OFW. You would need a hardware flasher in order to downgrade it.
I have the latest version of sony’s OFW, must I use a hardware flasher to downgrade or there is any other way ?
Unfortunately it’s the only way to go right now, only firmware 3.55 can be installed with CFW via software.
Okay I done all the above steps and I noticed it still said “4.21″ which you stated is normal. I tried to install 3.55 Rogero and 3.55 Kmeaw. I get an error both times. Saying it is already updated once its about to update. Am I doing something wrong? I used the Toggle QA before trying as well. A little help please if you dont mind.
Try installing it via Recovery mode, and also, you can try installing 4.30 v2.05 directly also via recovery mode
First of all, thanks Tech84 for the entire guide. i have multiman 4.18 and it says i have PS3 System: Firmware 3.55 [ SC-36 / Standard] can i downgrade it to 3.55 with this or do i have to downgrade it with another program? this is to upgrade it to ROGERO 4.30.
If you are on 3.55 you can upgrade directly to Rogero 4.30
downgrade from 4.30 to 3.55 please help me experts
What is your question sir?
Im on 4.21, none of my .pkg files will open, goes to black screen.. Toggle qa doesnt work either only blackscreen no beeps or restart… I need to get to 3.55 so I can remarry my bluray drive..
Hi,
I’m using the cfw 4.30 and I have many errors on various things. I cannot install a PSN game (error while trying to install the pkg) and 50% of the backups I try send me back error codes or go back to xmb.
Does a clean installation will help? I can’t remmeber but I think I was on cfw 3.55 kmeaw before installing rogero 4.30 (only updated it by recovery mode). Can it be the reason why I have so much issues or my usb dives suck?
Thanks for the tutorial anyway!
PSN games that used to run on 3.55 needs to be re-signed for 4.30.
Hello guys, i downloaded the Rogero 3.55 from the link but the file is named “V3.7A.PUP” is this correct?!
Anyone got the correct hash values so that i can check it out.
Thanks a lot (i am really new to this and fear ending up with a brick)
Yes it should be version 3.7a
Another question, when using a USB stick do i have to Format it to FAT32 as well? Or does this only count for External HDD?
You need to format it to FAT32 as well
i have 4.31 pleaze help me downgrade to 3.55… step by step
are you running 4.31 CFW?
hi everyone i tried your methode but it gave me “the data is corrupted (8002F957)”
try installing it via recovery mode
I have 4.21 version on my ps3 and i want to downgrade it to 3.55, i tried the methode which you gave us but i failed in step 7, it gave me “the data is corrupted (8002F957)”, and you said to me “try installing it via recovery mode” and i did but it gaves me “the data is corrupted (8002F2C5)”. Could you help me pleaaaase.
One thing you can do is install 4.30 v2.05 directly instead of going to Rogero 4.21
Hi, I said that I have 4.21 on my ps3 and what i want now is to downgrade it to 3.55
You mean you are on Rogero 4.21? Or 4.21 OFW?
Could you please tell me how i can know if my system is on 4.21 Rogero or 4.21 OFW ?
I would like to know if it’s possible to downgrade from OFW 4.25 to OFW 3.55 or CFW 3.55…
I really need to do it if I want to install Rogero’s last CFW…
Anyone help?!
Unfortunately you cannot install CFW on any OFW higher than 3.55 via software only, you would need a hardware flasher in order to downgrade the system to 3.55
Where do I get E3 flasher?
I would like to know if its possible to install latest MULTIMAN without installing ROGERO? I just bought a PS3 with Firmware 4.31, 320 GB (Cech-3004B). Can any1 help answer? Thanx!

installing CFW on any OFW higher than 3.55 would require a hardware flasher.
