OTA update for Z3 tablet compact?

[SilverWF]

HI there, I have a device sgp611, it has android 4.4.4 on it.

The problem is that there is no OTA updates available for me, not in the inbuilt update tool, nor if check by IDID number on the support site.

How I can install firmware with Android 6 on my tablet? And I mean guarantee install, not shaman dances with downloaded from 3Rd party sites firmwares.

Thanks.
