Hello XDA i have ordered this one http://www.gearbest.com/cell-phones/pp_170574.html and i have some questions if someone can help me.

Q1: is it official genuine model? because asus publiced
4GB RAM - 2.3Ghz CPU
2GB RAM - 1.8GHz CPU
and on gearbest is 4GB - 1.8Ghz CPU no NFC

Q2: im pretty sure it will not have my primary language (slovak). Is it possible to load firmware with my language? for example will this tutorial help me with language problem? http://www.androidheadlines.com/page/2

Q3: i hear that it will not sync my google contact with chinese ROM so will that tutorial help me with this too?

Q4: someone ordered same model from gearbest?

Q5: will i get OTA updates from europe after upgrading to WW_2.15.40.13 ?

thanks!
