Tested on a GT-I9515

The device status was modified when starting but official after these steps.



1. Fully unroot using SuperSU (also uninstall any system modifying apps adaway, xposed)

2 boot to recovery.

3. Wipe cache and reboot to system

4. Do your ota.

5. Have fun with the new software on your phone.
