Question Cannot download D80010o

I have the AT&T LG G2 D800.

When I manually update, it stops at 9MB out of the 57MB then cannot download. It says the server is unavailable after and that the server will automatically check for updates in 48 hours. I have done this 3 times now and this keeps happening. Anyone know how I can get the update OTA successfully without any rooting, etc. involved?

Also, does it matter if I have the AT&T apps disabled?
