I rooted a few months ago with kingroot then installed supersu. I uninstalled/unrooted with supersu, left the kingroot app (I no longer had root so I couldn't use it) then updated as normal with the official ota. Worked good, phone did not boot loop. Seems better I'm not real sure yet lol. I haven't tried to re root yet but I'll let you know when I do.
