Google is pushing out October’s Android security update (at least we’re assuming it is) to Nexus devices today and has done so by already publishing both factory image and OTA .zip files. This is the second security patch for Nougat and that means new Android 7.0 builds for a few devices. The security bulletin should be up soon as well.
As of right now, we have new Android 7.0.0 files for the Pixel C (NRD91D), Nexus 6P (NBD90X), Nexus 5X (NBD90W), Nexus Player (NRD91D), and Nexus 9 WiFi (NRD91D).
The Nexus 6 (MOB31H) also go new images, but as you can see, it’s still not Nougat.
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.
