The upgrading of the well known firmware for Roger PS3 in version 4.40 v1.03 has recently been released and I decided to move from the very good 3.55 to the newer version.
What you need:
The latest version of Rogero 4.40 v1.03 cfw
A USB Flash Drive or an external drive.
To have already installed one of the following versions: OFW 3.55, 3.55 Kmeaw cfw, Roger 3.55 cfw, Roger 4.21 cfw, Roger 4.30 cfw or Rogero 4.40 cfw.
Remove the game from the PS3 (if you have one), because during the upgrade it can "grab" the OFW from the game.
Download the CFW only from the official links (above link), so you can be sure that you have the original CFW and not nothing "tweaked".
First you have to do a NOR/Nand dump. Go to Multiman and choose file manager. There choose which file you want and with a circle choose to open it in hex. Here press Select, then Start and then in the first two choices select "NO" and in the third select YES. You need to have a USB Stick on the right PS3 slot before doing this, to save the dump file.
Download the "Rogero_CEX_4.40_v1.03.PUP" file and rename it to "PS3UPDAT.PUP".
Now make a new folder in the Root of the USB Flash (or the HDD) and name it "PS3". Within this folder make another folder and name it "UPDATE".
So you will have something like x:PS3/UPDATE (where "X" is the letter of the USB Flash (or HDD), where you will move the "PS3UPDAT.PUP" file you have previously rename.
Place the USB Flash on the right PS3 slot, turn it on and go to "System Update" and select "Update via Storage Media" and just follow the instructions.
Note that you should also upgrade Multiman, because older versions do not work with the latest version of Rogero, and you will also need to rebuild the "EBOOT" files of each game to run from Rogero (alternatively you can delete the "patched" files for the CFW 3.55 and replace them with the originals if you have them or if you can find them from the internet).
Info for Rogero CFW4.40 v1.03
Rebuilt the CFW with minimal patches needed for similar OFW Stability, also adding full compatibility with multiMAN Tools.
All known issues from v1.02 are fixed now (XMB PS2 Game Saves, Sequential Video Playback, Media Server always on)
Removed Cinavia Patch used on v1.02 because of some compatibility issues (When DEX4.40 is public it will be added properly again)
Added the ToolBox to [app_home/PS3_GAME] to restore multiMAN/StealthMAN launch mode from ToolBox.
Updated the ReactPSN patch to work offline without the need to log into PSN at all (Credits to Team Rebug for their original 4.30.1 Patch)
Added both noBD/noBT patches to allow installation on consoles with broken BluRay Drive or Bluetooth board.
This CFW can be installed fine from XMB Update over OFW3.55 or any CFW ver: 3.55/4.21/4.30/4.40
Added the needed patches for the Original "*Install Package Files" Credits to Szalay and "hidden Man".
HDD can be swapped/changed and the CFW will re-install without any problem.
Patched LV1 to disable LV2 Protection.
Patched LV1 to add peek/poke support.
Patched LV1 Core OS Hash Check (to prevent Bricking on non-dehashed downgraded consoles)
Patched LV2 to add peek/poke support.
QA Flag enabled by default to allow for easier downgrading using Recovery Menu.
RSOD screen bypass patch for RSOD machines (it won't fix the RSOD but allows the PS3 to boot fine into XMB)
PSN/SEN access is available but it's not recommended.
It can run games signed with Keys up to version 4.40 without any Eboot/Sprx patching needed.
The CFW can be used directly for Downgrading with Hardware flashers using the new tool PS3 Nor and Nand Auto Patcher v0.04
