Default [HELP] KDZ back to F180K

I wanna try AOSP 4.4 ROMS but first I want to get back to F180K fw but I can't seem to get things work. Even to the point of soft bricking my LGOG. But I still cant KDZ F180K fw. It always say low batt error even on full charged phone. Even tried swapping the phone modes in the flashtool, but to no avail.

Any thoughts that can help will be very much appreciated.
