It is what I have to use instead of a kdz with the LG Flashtool for the D800. Its how I go back to stock unrooted.

Yes use the LG Flashtool there is a tutorial in the AT&T LG G2 Development forums. It's pretty easy to do.
Here is my tutorial

Use KDZ to downgrade. Make sure you're using the right D802 files.

Use this http://forum.xda-developers.com/lg-g2/general/d802-bootloader-changer-1-1-jb-kk-lp-t3104380
And then flash a KitKat baseband then you can install KitKat Roms.

Possibly, download twrp from blastgator it is bumped and doesn't need loki signature.

If you really want to go on a KitKat ROM you will have to use the tot method to get to stock KitKat and then root your phone using stumproot/towelroot. Then use autorec for KitKat to install recovery then update recovery with blastgator twrp then install KitKat baseband then you can flash your KitKat ROM. Make sure to do wipe before installing new rom

In all honesty, if the method I have provided has not worked then flash back to stock KitKat and follow the guide I typed above.
