[UPDATED 12/9/16] All 3.55/4.XX+ CFW/Useful PKG's/App

Install Rebug 4.80 REX/D-REX from XMB:
Download the latest Rebug 4.80 REX/D-REX from the link above, and make sure your USB is format FAT32. Then on the USB make a folder PS3 and inside of the PS3 folder make new folder UPDATE then drag Rebug 4.80 REX or D-REX inside that UPDATE folder. Then go to System Update and Update via Storage Media. Make sure there's NO original game disk in the drive, NO game is mounted and that you DON'T Update via Internet or else you would risk installing OFW >3.55!

Enable QA and Activate the Spoofer:
Go to Package Manager > Install Package Files > PS3 Hard Disk and install Rebug Toolbox. Launch it under the Game column, go to Utilities and change Toggle QA Flag to Enabled. This is to ensure easier and safer downgrading. Now go to Selector and change System Mode to Rebug, this will activate the built-in spoofer to prevent accidental updates to OFW >3.55 and allow PSN access (not since OFW 4.70 was released). You can also change XMB Operation Mode to Retail and Debug Menu Type to CEX QA to ensure you have the Retail menus instead of the Debug menus which you probably won't need.

Arch Spoofer for 4.80 [ lastest update is v1.21]

Attention a spoof allows connection to PSN but does not protect the ban should be used as a quencher SYSCALL PSNpatch or another application in addition to the spoof !!!

Update v1.21 :
add support CFW REBUG REX 4.78.x [only in normal mode/untested]

add support all CFW's 4.78 CEX standard

Install note:
Delete your old spoof if you have one installed
Download and install the package
Launch the application, choose the version of your CFW and then choose to enable or disable the spoof 4.78
Then put yes to two successive questions (yes to reboot, yes to Hard reboot).
Console restarts and ok.

Note: Make sure you do not have a disc in your Ps3 before updating. Also this is ONLY for the people who are on CEX, I can't explain for the people who are DEX sorry.

How to update to any CFW
1.Plug your USB into your computer and on the root, create a folder called PS3 and make sure its in capitals
2. Inside the PS3 folder, make another folder called UPDATE also in captials
3. Now place your chosen .PUP into the UPDATE folder
4. Change the name of that .PUP file to PS3UPDAT.PUP
5. Plug your USB into your PS3 and head to system update, then update via storage media
6. Go through the process like a regular update

How to downgrade from any CFW back to 3.55 OFW

Note: Make sure you do NOT have a disc in your Ps3 before doing this.

Install Rogero 3.55 Downgrader
Install QA Toggle (if you already have it installed then skip this step)
Enable your QA Toggle
Install Rogero 3.55 CEX CFW v3.7
Install whatever CFW you would like over the 3.55
You can get all the files just click here

First you need to download Rogero 3.55 downgrader
Then Rename the downloaded file to "PS3UPDAT.PUP" and put it on your USB in: "USBPS3UPDATEPS3UPDAT.PUP"
While on any CFW version, go to System Update from XMB and install the Downgrader PUP.
After the Downgrader PUP install you'll be back on CFW3.55

Put the "toggle_qa.pkg" on USB and Install it on the PS3.
Install QA flag under "Install Packages"
Go to it and hit X, 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
"USBPS3UPDATEPS3UPDAT.PUP" Rogero CEX-3.55 CFW V3.7.PUP Rename this UPDAT.PUP
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 )

Note: If you get corrupt data when installing Rogero 3.7 3.55 CFW, just Turn on System Debug Update on the Debug Settings then try to update it again, it should work this time

So after you're on Rogero 3.55 v3.7 you can install whatever CFW you want, just place the file on your USB and rename it UPDAT.PUP then go to system update, update via storage, then follow the steps.

Note: Make sure you do not have a disc in your Ps3 before doing this.

How to downgrade Rebug 4.78.1 to 3.55 OFW:
If you have QA flag on, you can direct update to lower firmware but REBUG and Habib are the only ones with QA flagging.
QA flag is temporary, it gets revoked once you move CFW and you would have to re-QA. Some CFW cannot be QA flagged again because it isn't supported. (All REBUG firmwares have QA flagging supported, you turn it on through REBUG Toolbox or using Toggle QA pkg.)
Since you're on REBUG, you can direct update to REBUG 3.55.2, QA Toggle and you can update to any OFW or CFW.

For CFW not supported by QA flag, you use a downgrader .PUP update file to go back to "pseudo OFW but not CFW" 3.55. After that you QA Toggle and update to REBUG 3.55.2 or Rogero 3.55 V3.7. At this point, you can update to any OFW or CFW you want.
