Attempted Nexus 6P bootloop fix, then factory reset, now won't boot at all
I was able to fix it using the following:


After failing to boot select "Retry"
Immediately press power and down volume to enter bootloader
Enter Recovery
Reload bootloader from Recovery
It is now able to be seen by fastboot
Downloaded the latest flash image from Google
Ran the flash-all.sh


And then it worked. I immediately went in and set up USB-debugging
