Default [Q] LS980 Broken Glass and Digitizer

A fall of about just a foot cracked the glass on my G2. It wouldn't have been so bad if it hadn't also destroyed the digitizer, leaving on a small part of the screen usable. The bought the phone in February, so I was wondering if the LG warranty would cover the damage. If not, I could try to fix it myself. ETrade Supply does not have a screen listed for the LS980, but they do have one for the D800 (unfortunately currently out of stock): http://www.etradesupply.com/lg-g2-d8...h-lg-logo.html
Should this work with the LS980?

Also, does anyone know of a way that I can control the phone from my pc over usb, probably using adb. I would like to be able to at least backup the phone, but I can't even get past the pattern lock. Would it work to get a USB OTG cable and connect a mouse?
