What I've Done:
- Unfrozen all frozen apps within Titanium Backup
- Used Wanam Xposed to set system status to "Official"
- Set SuperSU to "Survival Mode" and disabled SuperUser
I'm not sure where to go next, as I don't want to have to remove everything from my device and start fresh again (I've already had to do that before!!). What should I do so that I can take OTA and keep my root status?
