You can’t unlock/root Google Nexus 6P. QFuse in Nexus 6P & 5X
Seems that Google has decided not to take any chances with Google’s Android Pay. They have rolled Google Nexus 6P with a hardware known as QFuse which is a ticking time bomb and gets triggered if you fiddle with the firmware of Nexus 6P. What?? Moreover this process is not reversible and there is no software that can (de)trigger the blow up of the so called QFuse in the Nexus 6P.
Till date users are having their time unlocking their Nexus devices and getting the full potential of the device at their end but news like these will not let the users fiddle with the firmware anymore.
