Google just posted the Android security update for August 2017 and the files are already live for a number of devices.
So far, we are seeing 7.1.2 files for Pixel and Pixel XL (NHG47Q, NJH47F, NKG47S, NZH54D), Pixel C (N2G48C), Nexus 6P (N2G48C), Nexus 5X (N2G48C), and Nexus Player (N2G48C).
We’ve also got new 7.1.1 files for Nexus 6 (N6F27I, N8I11B) and Nexus 9 (N4F27K, N9F27H).
The notes here for each Pixel update indicate that NHG47Q is for Verizon models, NZH54D is for Deutsche Telekom, NKG47S is for T-Mobile, Project Fi, and Rogers users, while NJH47F is the generic build for everyone else.
