Not so long ago, Sony released Firmware 4.80 which was an yet another stability update. Rebug CFW is back as well with a few new features. Of course, the Cobra 7.3 payload isn’t missing from this release. That means you will no longer need the PS2 Launcher to play PS2 game,s you can launch them now directly via the Disc Icon from the XMB and many other cool features! But take a look yourself below.
How to install 4.80.1 Rebug REX/D-REX
Download the Rebug PS3UPDAT.PUP from the official Rebug site (there are two versions, one for CEX and the other one for DEX Systems, choose the one you need)
Create on a FAT32 formatted USB Flash Drive a Folder called PS3, then into this one, another one called UPDATE
Copy the PS3UPDAT.PUP in the UPDATE Folder.
Plug in the usb flash drive to your PS3, Go to Settings > System Update and install it.
You’re now done and can setup the CFW.
Like all Custom Firmwares, you can only install 4.80.1 Rebug if you’re already running a Custom Firmware, or Official Firmware 3.55 and below on your PS3!
