Sorry for the confusion that I created.
I am not a specialist either; I just recalled my experience with my NEXUS 5X I had acquired 
on eBay to flash a Google-free OS. There, to become root, I had to follow a procedure 
where the touch-screen was indispensable.

Maybe it is carrying coal to Newcastle, but you may find a solution on https://
