Mate 8 model identification to upgrade to EMUI 4.1

Hi all,

I would like to update to EMUI 4.1 but I am not even able to identify the Mate 8 model I own....

Looking at "Settings", "About", it says :

Model: Next
Build: NXT-C900B12

Looking through the dialer menu (* # * # 2846579 # * # *), it says:

Hardware version: NEXT_TUCL_VN2

This is a 128Gb Mate 8 Dual SIM, bought in China.

Can anybody help me to identify the model and even better which OTA, if any..., I may apply to upgrade to 4.1?

Thx a lot !
