Busted screen, any mirroring/backup advice?

[greycobalt]

The screen on my 6P stopped working tonight. No idea what caused it (unless it was the May security update), but I've already processed a replacement through Fi.

What I'm trying to do now is to figure out how to (hopefully) use my phone while waiting for the replacement - I work from it a ton. At the very least, I'd like to save the data. I initially tried mirroring it to Vysor, but that requires the phone to be in PTP mode, which I'm not able to do without a screen.

Any advice on a complete backup/restore option that doesn't require me having a screen, or a way to remotely enable PTP? I'm not rooted and am running full stock. Thanks in advance!

I haven't seen one for the 6P yet (possibly I just haven't looked hard enough) but my old Samsung Galaxy S3 had a dock with HDMI output that allowed me to mirror the screen without having to fiddle with the screen.
Perhaps a similar solution would work for you.
