Hey there! Stuck updates and connection issues are no fun at all! We'll be more than happy to take a look at that with you. Let's see what we can make happen.
To get started, unplug your router! Let it fully turn off and chill for a bit (only a minute or two) then plug it back in. Once it starts back up and stabilizes the connection, your headset should reconnect and finish it's update.
If that doesn't kickstart everything, go ahead and hard reboot your headset by holding the power button down until the headset restarts.
Please, let us know how it goes. We have more tricks up our sleeve to get you up and running if you need 'em!
