What you need is a DEX PS3!
Mine is PS3ITA 4.50 DEX!!
We are going to install REBUG 4.65.2 D-REX!!!
(NOTE)
A Fresh Install Of the FW before doing this lowers brick chance.
You must do these steps in order.
Make Sure Debug Setting Are Like This:
Np environment = np
Release Check Mode = Development mode
Boot Mode = System Software Mode
Network Settings For Debug = Single Settings
Files Needed:
REBUG 4.65.2 D-REX
REBUG TOOLBOX 02.02.02 [Latest*]
4.66 D-REX Spoof for 4.65.2 D-REX
multiMAN v4.66.10
PSNINJA v4
CCAPI v2.60 Rev2
First; you need to be on DEX CFW
Second; you need to have no spoofs installed, to be more safe
Third; you need install REBUG 4.65.2 D-REX
Fourth; you need to install REBUG TOOLBOX 02.02.02, once installed check that System Mode is set to "Normal" and that Cobra Mode is set to "Disabled"
Fifth; you need to install the spoof homebrew, so install the package file and run the software
Sixth; you need to install it then activate it... Your PS3 should save/backup some files and then ask to restart... do a HARD reboot
Seventh; you need to check that your PS3 is now on 4.66 so goto your Settings>System Information on your XMB and you should see that its 4.66
Eighth; you should now be set to go online
If you want to have less chance of being Console ID banned then make sure to wipe your PS3 history everytime after you run homebrew.
