G933 Power/Charging Issue: Won't power on

Updated:  11/20/2018 03:30 AM
If you have a G933 that is not functioning at all (does not charge, does not turn on, does not connect, and so on), the problem may be due to: 
  • Faulty headset
  • Firmware needs to be updated
Try the following to recover the device:
Perform a hardware reset 
  1. Plug in the G933 to USB power. 
  2. Remove the left side plate (on the mic side). 
  3. Press and hold the hardware reset switch with a pin for two seconds, as shown below. Repeat the two-second press twice.

  1. Make sure that both the headset and the wireless adapter are connected to the computer via USB connection before you run the update.
