Bootloader unlocking veterans probably did the same thing I did when they first got their Nexus 6P. Of course the first thing I wanted to do was get that bootloader unlocked and get TWRP installed. I plugged my 6P into my PC and proceeded to boot the phone into fastboot mode so I could unlock the bootloader. After typing the normal command "fastboot oem unlock" and getting an error I scratched my head. In these situations google is indeed your friend.

What I found within a few minutes of research is that the Nexus 6P requires a new command for unlocking the bootloader. The new command is as folows,

"fastboot flashing unlock"

Other commands include:

fastboot flashing lock

fastboot flashing unlock_critical

fastboot flashing lock_critical

fastboot flashing get_unlock_ability

I am not sure why the change occurred, but this is generally the same easy process you just have to remember to include the "flashing"!
You also have to download the latest Android SDK. I had an older version and I couldn't unlock my 6P with the old command and the new command wasn't recognized. I was mightily confused until an XDA'er pointed out my mistake.
