Location [Q] Urgent help! update auto installed, and bricked my phone.

I have the Lg g2 D800 varient, and tonight I got an update for 15.4mb, that pushed without my permission, and now my screen is on a black screen, upon rebooting after said update was installed. I am rooted, but no plans to update to 4.4, it just did it without consent..

Help?

Edit:

Stuck on a bootloop, the LG logo flashes for a second, then its a lighted black screen. I plug my phone inot the pc, and 20 windows popup asking If I want to format G drive.

No twrp installed.
