Long time Virgin Mobile user - big fan. Upgraded to a Nexus 6P on the $60/month plan (+$5/month for the Nexus 6P). Have loved the phone - best Nexus ever! But... tonight, while taking a photo, the phone froze and then went into a bootloop. I haven't been able to get it to boot properly since. I've googled a heap and the main suggestion is to use adb to sideload the 7.1.1 OTA update onto the phone. Tried that, but as I hadn't unlocked the bootloader, which is how it's sold to us, and we're not meant to unlock it unless fiddling with the OS, it wouldn't read it across - provides a "cannot read file" error message.
Anyone got ideas? Apparently this is a growing issue with the 6P now?
I had a look at what Google could find for me and top of the list was this article from Android Authority that details how some users are experiencing this sort of issue after the latest update to Android Nougat.
The good news is that it appears that at least one user out there affected by this issue was able to fix the problem by clearing out the cache and then wiping all data on the phone. The bad news is that this also means rebuilding your phone's installed application list, preferences, contacts, etc. from scratch.
Let us know how this course of action pans out for you.
