don't install Rebug over Rorgero it won't work just downgrade using Rorgero 9.99 downgrader and then Enable QA Flag then after put 3.55 kneaw on then upgrade to 4.46 Rebug hope this helps :p

You Need To Go To

Rogero=Cex

Rebug Rex 3.55=Cex

Rebug Rex 3.55=Dex

To Whatever Dex Firmware you need.

OFC you'll need to research this before doing anything.

To do this nice and safe install QnA PKG and check your enabled first. Once you have checked that you are install Rogero 3.55 downgrader or rebug downgrader this will now put you on 3.55. From here, you just install any custom firmware of your choice. If it's below 4.55 you install 4.55 spoofer and your done.
