How to unroot lg g3?

[radmilalg]

Is there some way in which i can fully back my phone on the state before rooting(with all settings,programs,and ofc changes i made when he was rooted).I dont wana back him on factory settings or something like that.
Is there some program or method to do that?

No, they won't know that your G3 was rooted. Root only apps, mods that require root, etc will no longer work if the phone is unrooted.

Why do you want to unroot?
