Google is pushing out July’s Android security update to Nexus devices today and has done so by already publishing both factory image and OTA .zip files. They also provided the typical security bulletin as well.
As of right now, we have Android 6.0.1 files for the Nexus 6P (MTC19X), Nexus 5X (MTC19Z), Nexus 5 (MOB30P), Nexus 6 (MMB30K, MOB30O), Nexus 7 2013 (MOB30P, MMB30M), Nexus 9 (MOB30P), and Nexus Player (MOB30P).
You can grab each image or OTA file at the links below. For instructions on how to flash a factory image, here you go. For instructions on how to flash an OTA .zip file, here you go.
