I was trying to find such information but with no luck.
What is my goal? The most painless migration from Omni to CM11 (or revert).
I'm wondering is it possible to preserve apps and their settings but change the whole ROM or is there any other way to move apps and their settings from one ROM to another (I know about Ti backup and other apps like this but anyone tested this solution?) I don't care much about ROM settings but apps are important for me.
This I9100 is my only phone so I can't stuck with "blank" phone.
Thanks in advance!
