[AC Question]

Hi,

I have a Nexus 6p and inadvertently deleted the OS when trying to fix a boot loop. Now I have an even bigger issue. When I try to fastboot and flash the stock image file, my phone won't go into fastboot mode. I have downloaded all the drivers from the SDK and such, but I see that a lot tutorials say I need to put the phone into USB debugging mode. Obviously, I can't do that if I can't load the phone into an OS. When I connect the phone to my computer and run a command prompt, it doesn't list my device when I type "adb devices." I get a message that says "adb server is out of date. Killing."

Is there any way to fix this so I can flash a new OS?
