This works with 4.40 cfw

This CFW can be installed fine from XMB Update over any CFW version ( 3.55 --> 9.99 )
RSOD screen bypass patch for RSOD machines (it won't fix the RSOD but allows the PS3 to boot fine into XMB)
It does have all the features from Rogero CEX-3.55 v3.7

Downgrading back to CFW3.55 from any CFW version ( 3.55 --> 9.99 ) is always possible using the following steps:

Download the Rogero Downgrader PUP from the links posted above.
Rename the downloaded file to "PS3UPDAT.PUP" and put it on your USB in: "USB\PS3\UPDATE\PS3UPDAT.PUP"
While on any CFW version, go to System Update from XMB and install the Downgrader PUP.
After the Downgrader PUP installs you'll be back on CFW3.55 (but the syscon version will still have 9.99 in it)
In case you didn't have it Set Before, Enable QA flag by following these steps:

Enable QA

Download the Rebug QA_Toggle package from here ---> You must login or register to view this content.
Put the "toggle_qa.pkg" on USB and Install it on the PS3.
Run the "Rebug Toggle QA" from XMB, the screen will go Black and you will see HDD Led activity then if all went fine you will hear 2 or 3 Beeps and the PS3 will Restart back to XMB.
If you want to make sure QA flag was set, go to "Network Settings" then apply the following key combo (all at the same time):

L1 + L2 + L3 (press left stick) + R1 + R2 + dpad_down

You should see Edy Viewer, Debug Settings, and Install Package Files if done correctly.

Now put "Rogero CEX-3.55 CFW V3.7" on your USB in: "USB\PS3\UPDATE\PS3UPDAT.PUP" ---> You must login or register to view this content.
Start the PS3 and install "Rogero CEX-3.55 CFW V3.7" using the System Update from XMB.
Once you're back on Rogero CFW3.55 v3.7 you can now install any CFW you want using the System Update from XMB
( or Recovery Menu if XMB Update didn't work ).

From Rebug 4.21 I used this downgrader and it said 4.21->3.55 during the fw install. But after it was finish it still displays 4.21 in system information. When I try to install rogero 3.55 v3.7 from there it does not recognize update data on usb from the xmb. So I went into recovery mode to try and install 3.55 v3.7 from there and it is asking for 4.40 or newer fw. Any ideas? qa is on. p.s. When I make a backup of my flash again it says Im on 3.55. Yet still cant install Rogero 3.55 v3.7.

go to debug setting and turn on sytsem update debug and install the fw 3.55,i pretty sure thats what you do

No applicable update data was found. Got the Rogero 3.55 v3.7 straight off Tortuga-cove. I guess I'll try the whole process again.
