Why won't my Samsung Note 4 update?

[AC Question]

The update auto starts by downloading and then states it will reboot to install the current updates. Once the phone shuts down it pops back up with recovery booting and a screen that says the update failed. This has been going on for several months now. I have AT&T as a provider and they can't answer as to why it won't process the update either.
