For a year and a half now I haven't used a Huawei G6 from which I removed the sim card once I got a new phone.
Today I tried to turn it on, charge it, reboot it by holding all buttons or only the power buttons for a minute - no response.
When I plug in the phone to a charger, for a moment the red light shows but then instantly ends.
Is there any way to get this phone working or should I go to some store?
