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.

NOTE: Please make sure to disconnect all other headsets from your computer before beginning this firmware update.
  1. Make sure that both the headset and the wireless adapter are connected to the computer via USB connection before you run the update.
