If you are unable to complete a firmware update, please take the following steps:
1. If you have access to a second computer, try firmware update on backup machine.
2. Try quitting and restarting SteelSeries GG
3. Fully Uninstall/Reinstall SteelSeries GG
Change the type of port your device is plugged into. For example: if your device is using a USB 3.0 port try a 2.0 port and vice versa please also ensure you are not connected to HUB ports or external hubs to ensure your drivers load correctly, and that the device receives adequate power. Also, virus protection software has been known to hinder the firmware update process through protocol filtering. Could you please add the SteelSeriesEngine.exe and SteelSeriesEngineClient.exe to your exclusions list to see if the firmware update will be successful? You may have to reboot after making these changes. Then try launching the Engine software again to do the firmware update.
