Default [Q] Rooted D802T

Hey guys, so I rooted my LG G2, as of now Australia hasn't recieved the Kitkat update.
I was wondering if I could flash the stock 4.4 onto my device and how i would go about doing this? Ive only ever rooted and flashed cyanogen mod before (on my Galaxy s3).

This is my phones software info:
