Default 4.4.2 Stuck at boot screen

For some reason I am unable to flash to any KitKat Roms; I can however flash 4.3.

I have tried CWM 6.0.4.3 and TWRP 2.7 both have the same effects.

I did flash Carbon once and and it worked for about a week and than my phone froze then rebooted and was stuck at the boot screen. The only way I could fix this was by flashing a 4.3 rom.

I would like to be able to enjoy KitKat..

Thank you in advance for any and all help!
