When I installed this weekly 8.10.11 in first boot it find mobile network, when I booted phone again it doesn´t found mobile network.
If you enable developer option "Skip screen lock" phone does not find mobile network in second boot. Problem is related that option.
Dirty flash, cleared dalvik...
Mi mix 2 quick charge problem on usb3 wire (charging only 300Ma on ampere) , was working before.
When I connect cable that come with phone (usb 2.0 I assume) ampere gives +3000Ma.
Tested with Nillkin elite cables (usb 3.0 blue connector) , I have two of them and they worked before.
