Nexus 5 Unroot: Update Possibilities? I somehow one-click rooted my Nexus 5 (without a computer) but want to unroot. If I go to Settings >>,About Device >> Update and install an update if there is one, will it delete root or get stuck on the boot logo because I'm root? I don't want to have issues but I also don't want root. Now I downloaded SuperSu and used the Temp Unroot option which basically just deletes root temporarily unless that option is DE-selected. So basically I don't have root now (I checked) but it's still there, I just want to know 

1) Can I update without having problems? I have T-Mobile. 

2) Is there an app that can just delete root for good, permanently?
I've found a solution. 

Go to SuperSu >> Settings >> "Fully Unroot This Device." Done.
