Hello mrgameraddict, Rogero 4.40 is a good CFW (very similar to 3.55 Kmeaw but its a 4.40 CFW),you can spoof it to 4.41 to play online at your own risk.
Rebug 4.41.2 is very good too especially if you wanna mess with trophies, savegames, region... etc & you can play online too.
keep in mind that if you unlock the trophies you can sync them online,in fact you can sync them but they won't show up,i tried it once they didn't show up on my PSN account,but it showed up on my Facebook it was funny,anyways if you want to install use the QA psg
1. Download QA Toggle pkg http://www.ps3news.com/ps3-cfw-mfw/t...e-is-released/
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,or maybe your chin or mouth, LOL
7. If the QA Flag was done correctly, you will see Edy Viewer, Debug Settings, and Install Package Files.
Now to system update assuming you chose one of the above CFW,download the PUP
1. Create a folder on your External HDD & rename it to PS3
2. Create a another folder inside the first one & rename it to UPDATE (must be in cap)
3. Put the pup you downloaded & rename it to PS3UPDAT so it can be like this PS3UPDAT.PUP
now connect you External HDD to the PS3 in the right USB the one next to the BD & eject any BD or Disc inside the PS3 go to system update, choose update from storage media, follow the instructions & voila.
Have a nice day.
