(adsbygoogle = window.adsbygoogle || []).push({}); I'm currently on Rogero 4.21 CFW and I'm trying to get to PS3ita 4.21 DEX CFW but everytime I go to update it say's update to Firmware 4.40 or higher and when I continue it says no software found on your media device. If someone could help me it would be very much appreciated and I shall also give you +Rep.

you need to be on 3.55 in order to isntall DEX, downgrade with a downgrader and follow a tut on the forum, there are loads of them here!

succes
