General Mobile GM 8 shut down and won’t turn on: what to do

If your General Mobile GM 8 will not turn on, charge it for a while with another charger and cable first. Then hold the power and volume down buttons together for a long time to force restart. Call the phone: if it rings, the screen is the problem. If there is no response, the battery, port or board should be checked.

  • First charge it for a while with another charger and cable.
  • Force restart with the power and volume down buttons.
  • Call the phone to tell screen from phone.
  • No charging sign may mean a battery or port fault.

Phone works but the screen is black: what to do

If your phone rings or vibrates but the screen is black, the phone is on; the problem is the screen or its connection. Force restart and charge it first. Shine a torch close to the screen in the dark: a faint picture means a backlight fault. If it started after a drop or liquid, the screen is usually replaced.
