I have an axon 7 mini (B2017G, USA).
I have problems with the network that does not detect. I have tried everything and was told that the ROM 6.0.1 android marshmallow solves the problem.
Someone has this Rom to give me, I will be very grateful.
B2017G is the EU version.
Which android version are you using on your device right now?
Did you try Version 1.2.0B15?
