You will need a backup of your efs at version 1, search and read for the many who have ended up with no signal.

Downgrading from 4.3 isn't recommended.

Hello !

I'd like to do the same thing, but I've got a 4.4.2 rom Stock and I'd like to go back to 4.3. I searched on the Internet but I didn't really find good stuff..
Any idea on how may I do this, if It's possible?

Thank you
