[Q] Note 8.0 LTE (GT-N5120) Kitkat 4.4 topic

HI all,

I'm a Hong-konger. My tablet is GT-N5120 LTE version. Samsung does not release 4.4.2 firmware for this region.
Can I install other region's one, such as UK or Singapore firmware for my tablet ?
Just worry if the firmware in other region make the phone feature of this tablet not work.

regards, Ray
