How to downgrade to 3.55 from any CFW

Written by Tech84 on April 11, 2013

This is for PS3’s already running CFW and you want to downgrade back to 3.55 for testing purposes, or to try out other firmwares or for some other weird reason you may have.

How to downgrade to 3.55 from any CFW

A USB Flash drive (Must be big enough to accommodate the installation files) or an external HD
A PS3 running any cfw (this means this work on Rogero 4.21, 4.30, 4.30 V2.05, 4.40 v1.02 and Rogero 4.40 V1.03)

Here’s how to downgrade to 3.55 from any CFW:

Download the Rogero downgrader PUP here. (Mirror here)(And another here)(And one more here)
Download QA Toggle pkg here

Here are the steps to downgrade to 3.55 from any CFW
Remove any discs inside your PS3 when performing the update.

1. Download the “3.55 Rogero Downgrader RSOD.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 3.55 Rogero Downgrader RSOD.PUP (which is now named “PS3UPDAT.PUP”) inside the “UPDATE” folder
5. Insert the USB or external HD on to your PS3 and on the XMB, 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 Rogero CFW3.55, it wills till show the old CFW on the system settings, this is normal.
8. Now you can either stay on 3.55 or update to a higher cfw version.

Important!: Before installing any higher OFW or CFW, you need to Toggle QA first. The reason your PS3 still shows the old CFW version is because the syscon version will still have the old cfw version. Hence we need to Toggle QA first because if you update your PS3 without toggling QA will results to problems such as bricking (and you don’t want that).

Here’s how Toggle QA:

    1. Download the QA Toggle pkg here.
    2. Copy the file to the root of your USB or external HD
    3. Insert your USB/External HD to your PS3
    4. On your PS3, go to “Install package Files” and install the QA Toggle PKG
    5. 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.)
    6. 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)
    7. If the QA Flag was done correctly, you will see Edy Viewer, Debug Settings, and Install Package Files. (if not, repeat step number 5, 6 and 7)
    8. Now you can update to any CFW you want.

To make it short:
1. Install the downgrader PUP
2. Toggle QA
3. Install install any CFW you want.

    • Ted says:

      Try installing via recovery mode, then is any message comes up, pres select+start

      also try a different download from the mirrors, maybe it got corrupted at some point while downloading.

      Is your 4.41 PS3 running CFW? Because this guide only works for PS3’s already running CFW on their systems.

  23. Bilal says:

    Will it work on habib 4.60??

  24. Kate says:

    Can I use this method for Rogero 4.6?

  25. ELCUCO says:

    The reason you guys are having issues is because there is a step missing in this tutorial:

    1) Install 3.55 Rogero Downgrader RSOD.PUP as instructed above, this does get your console at 3.55 but your syscon will is modified to allow up to 9.99 to be installed.

    2) Install Toggle QA as instructed above.

    3) Install CFW V3.7.PUP (you can get it here)
    this will reset your syscon to 3.55 and allow CFW or OFW 3.55 to be installed properly.

    4) Install any CFW or OFW 3.55
