Xbox Elite Series 2 controller not updating on PC

Hi

I wanted to update the firmware on my new Xbox Elite Series 2 Controller.

I installed the Xbox Accessories app, and it prompted me for the update, and I started it

But then nothing happens. Nothing at all. The app is not dead (the controller on the loading screen of the app blinks slowly) but that's all. No progress, no error message, nothing.









I tried:

- Using a different USB Cable

- Resetting the Accessories app

- Reinstalling the app

Any help is appreciated!

:)
