(adsbygoogle = window.adsbygoogle || []).push({}); Alright so I had a Rogero 4.50 CEX, with my desires to RTM... I used Rogero's 999 Downgrader. I'm now on the downgrader's cfw.

I was reading about PS3ITA 4.50 DEX, and I think I read that you could install it over 3.55 like a normal CEX CFW. Is that true? If it is what extra things do I have to do from where I am right now?

Edit: and yes... I realize I didn't need to downgrade to convert to DEX.
Edit 2: and I do have qa_toggle'd I installed the pkg and did the button sequence in network settings and I have "edy viewer, debug settings, install package files"
