Phew. Been banging my head against the desk for a while. Finally got the OTA Nougat installing on my Nexus 6p. This is how it goes.
Initially - nexus 6p in standard boot mode was recognised by my x64 Win10. Installed Android Studio. Ran adb reboot recovery to put my phone in recovery mode, used the key combo to get to menu, activated sideload from ADB but.... my Win10 machines would not identify my nexus 6p.
Adb devices and sideload would not return a device. Windows Device manager was empty too.
Turns out I was missing two items:
1. The Google USB driver - which I had to get from Android Studio/Configure/SDK Manager/Android SDK/SDK Tools.
2. Because it was a fresh install of Android Studio, it only installed with Android 7 platform. Had to select Android 6 platform from Android Studio/Configure/SDK Manager/Android SDK/SDK Platforms.
Then, after connecting the nexus 6p in standard boot mode (non-recovery) had to update the driver for 6p from Windows Device Manager (which showed up as ADB interface within USB Devices section). The automatic search re-categorised 6p to Android Phone/Android Composite ADB interface.
Next, used adb reboot recovery to boot into recover mode. Unplugged and reconnected the phone, switched to ADB sideload mode and Windows Device Manager recognised the device.
Hit another snag - this time side-load erred "cannot read zip file". After mucking about with renaming the file and re-downloading a couple of times, decided to rename the image using command prompt. And this time side-load read the file.
Conclusion:
=========
Need the correct ADB drivers.
Need the correct paltform tools for the current version on the phone
Rename the OTA using command prompt (rename command)
Hope this helps.
