I am not sure of any method to remove it on MK2. Maybe triangle away. I suggest doing a ton of reading.

IF you still have root because you used survival mode, you can actually go ahead and uninstall SuperSU, and reinstall it and update the Database, and reboot your device TWICE, this usually does the trick.
I would suggest at least trying it before the triangle away crap.
Also. If SuperSU is installed as a system app, just use a root uninstaller from the play store and reinstall it and then update the DB.
