(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.
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)
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
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

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.
