[Q] I want to unroot my nexus and factory reset? topic

Tons of crap on my nexus 4, and I want to reset it like fresh out of the box, unrooted, and everything deleted. Theres a guide on how to unroot it back to stock 4.2 but I'm not sure if it will work in the case of me having 4.4.2

Any other ideas? I heard there's an option in SuperSu but I can't upate the binaries.
