I am currently on an unlocked and rooted Nexus 7 on 4.1.1 running on a stock ROM. Nothing has been modified besides it being unlocked and rooted. Will I lose my root if I update and if so, what can I do to avoid that during the update progress or after the update? Sorry if this has been asked before but I'm really anxious to get rid of the OTA popup in the top left and get landscape finally.
