AC Question

My LG G3 is stuck in the middle of a root and the firmware won't update!

What I'm Using:
Verizon LG G3 (VS985)
LG One Click Root

What's going on:
I'm at 90% completion on the root, and after a reboot, my phone went through the app optimization and then went onto a Firmware Update screen.

Update Screen says "Do Not Unplug USB blah blah... VUSER B11... Modified and it has a percentage bar. Bar is at 0% and hasn't moved since it switched to that screen ~30 minutes ago. What do I do?!
