(adsbygoogle = window.adsbygoogle || []).push({}); i'm on rebug Rebug 4.46.1 REX (DEX) now and planning to upgrade to PS3ITA 4.50 DEX

but i want to know how to go back to rebug 4.46 or other 4.50 cex cfw

can anybody has idea for this?

1. Find the 3.55 DEX downgrader and downgrade to 3.55.
2. Next install 4.46 D-Rex Rebug.
3. Next Open up toolbox and switch back to CEX.
4. Install the CEX Firmware you want.

Do i have to go back to 3.55 first?
someone said i can just install 4.46 D-REX directly on 4.50 PS3ITA DEX

No you have to use the 3.55 dex downgrade first.
