These steps worked for me after struggling 1 hour, Not needed to connect to Chinese server.
(1) Turn Off your Wi-Fi
(2) Turn Off your Mobile Data
(3) Turn On "Install via USB" from Developer Option of your device.
4) It will show the Error "No network found"
5) Now Turn On your Mobile Data
6) Again Turn on "Install via USB"
7) it will work, now Happy!
