Any news on MM note 5 AT&T?? (Update: Out Now!)

[srinathp1988]

it sounds like you sideloaded the first Marshmallow release posted on XDA. If your build number ends in PE5, you won't be able to receive any further OTAs because the official release was PE6, and there's no upgrade path from PE5 going forward. If that's the case you can ODIN flash back to PB2 Lollipop, and then your phone will prompt you to upgrade to the current official Marshmallow build with the July security update.

I searched for stock firmware for At&t note 5 but i am unable to get it. Search results say that at&t note 5 cannot be rooted or modified and hence stock firmware is not available. Does anyone know how i can go back to stock so that i get the official Marshmallow update?
