Default Need some advices please.

Hello , Now i tryed 2-3 roms , And i really like kitkat ones, 4.4.2 so i would rly want another one cause of some lack of some stuff, Currently im running droidkang, But i cant seem to get LTE up and running, I would like a new kitkat room with lte included, And if i flash another 4.4.2 do i need to KDZ first or just the normal wiping ?? Thanks
