Please read the F.A.Q. link in my signature. You can update from the Recovery mode: Volume UP + Power.
And I suggest you to transform your phone into the “global one”. Read Method 1 of the following link.
I am confident that Gearbest fucked up your phone! So best is in my opinion.
- update + clear data to a public Chinese firmware “A”
- use Method 1 of the guide
- install whatever firmware you want (clear data, when you upgrade)
