Broken Nexus 6p Recovery So while I was overseas in Vietnam I dropped my Nexus 6P and broken the screen.
The screen is completely black and completely unresponsive however when I use the fingerprint scanner it still vibrates.
Stupid me decided to restart the phone by holding down the off button, which I immediately regretted as of course, Now I must enter my PIN to be able to get into my phone.
SO basically, Im asking if its possible to recover any data from my Nexus 6P with a completely unresponsive screen, and requiring PIN on startup.
I Believe that debugging was enabled
Yes, you can. Connect your phone to a PC and use ADB to backup your data. Follow this guide to setup ADB, Fastboot and the Android SDK Platform tools on your PC: https://forum.xda-developers.com/nexus-6p/general/guides-how-to-guides-beginners-t3206928

Load your phone into fastboot mode by holding the power button and the volume down button at the same time, from there you can choose recovery mode by the volume and power buttons navigation of your phone, then access and copy your data from your PC by ADB. 

Alternatively you could temporarily load a custom recovery as suggested here:  can fastboot be used to backup device?
