Default LG Flash Tool updating

Is it safe to update to KitKat using the LG Flash tool coming from firmware D80010d on an AT&T d800? Or would it be safer to track down the o and q updates, apply them, and then apply KitKat?

I think somebody may have posed this question over in the development section, but the English/grammar made it a bit unclear. Please accept my apologies for any redundancies.
