How do I "unroot" my android device Now with Pokemon GO pushing the new update and not allowing rooted devices in the game, I want to reverse that.

So how do I unroot my device

Bonus: How do I manipulate the app into thinking I do not have root access

Edit: I used SuperUser's Full unroot option but it does not remove root access. Either SuperUser has a problem or my phone's jacked up
If you want to unroot only to play Pokemon Go, you don't need to do so.

Just root with Magisk:


Download the magisk installer from the official post on XDA-Developers
Flash it with the custom recovery.
Install the Magisk app (also in that post on XDA)


Now, to hide root from Pokemon GO:


Go to Magisk Hide and enable Pokemon GO
Go to Settings, and press on Hide Magisk Manager


It will take a while, just let it work. 
When it finishes, reboot your device and open Pokemon Go.
If it still detects root, clear the data of Pokemon Go.
