Don't!!! Never flash the JB version over KK if u use RSD-Lite (The phone will be software bricked). Only do it manual by flashing only the system, recovery and boot and erasing the data and cache by using fastboot. Look it up

I did it i was on cm11, did an mistake and the phone was in bootloop. Every solution didn't work so I've flashed with RSD lite and after finishing I saw it was a jellybean rom but it worked. after the first start my phone said there is an update to kitkat for download. (I have an unlocked bootloader)

Oh wait, ...

We are talking about JB. KK doesnt change anything important. Its safe to flash.
As long as u dont touch a ICS package its all good.

Sry, my bad.
