[Q] LTE not working on kindle fire HD 8.9 (JEMLTE)

Hi
I was using my kindle with its stock rom and cellular networks was working without problems .

then i installed cm 12 (after changing the bootloader and installing TWRP recovery) and i didn't see the Mobile Network option
inside my settings .

i checked it back and discovered that it was for wifi only version then i found liquid smooth 3.2 for the lte version, installed it and it was showing no sim indicator .

i didn't take any backups for the system,recovery,boot img files

I returned to stock using the files(system,recovery,boot) uploaded in this guide :

and cmd commads mentioned in this thread :
http://forum.xda-developers.com/show....php?t=2761560
