Xbox Accessories bricked my controller

I was having the same exact problem. Xbox Accessories it told me that I needed to update. When I clicked update, the process failed, and the controller no longer functioned.

Your suggestion to use the Xbox Accessories seems a bit silly as it was using that app that bricked the controller in the first place.

I actually did manage to fix it though! Hopefully this helps people:

The problem seemed to be what USB port I was using. I have a USB hub, and with the controller connected to the hub, Xbox Accessories detected the controller, but attempting to do a firmware update bricked it.

I disabled bluetooth on the PC, unplugged the USB cord from the controller, turned the controller off

Then I plugged the USB (A) into a port directly on the back of my PC.

I plugged the USB (C) side into the controller, which turned it on.

(controller still bricked at this point)

I then opened Xbox Accessories app and did a firmware update.

This time the progress bar started moving, and the update was a success.

The controller is now working as intended.

The X1 will power on and work without the controller, it will not without the power brick.

In my eyes, the brick is a component of the system, and not an accessory.

Can I buy a 3rd party power brick and still have the system covered under warranty if it fries? I'm pretty sure that warranty claim would be declined. However, if it's just an accessory, there should be no issue right?

I do use the Bluetooth to connect my controller, no wireless adaptor.

I actually saw that Xbox accessories app (it's not installed) but I'm afraid to use it because I saw someone bricked their controller using it and they had to make a ticket for replacement for a controller. Also the accessories app doesn't have a good rating in the store.

Anymore suggestions will be greatly appreciated.

Another victim here. Received my brand new Elite controller today, bricked after the update from xbox accessories app.

It may have been windows 10 anniversary update drivers that caused issue. Anyone here is facing the same brick issue without the anniversary update on their windows 10?

I just had exactly the same issue

I finally installed Windows 10 and knew that this was a prerequisite for updating the xbox one controller firmware. Installed the "xbox Accessories" app and attempted to update the firmware.

The update stalled at 0% and waited 10 minutes and hit the back arrow. The xbox accessories app no longer sees my controller...... seems that the app bricked it.

Like the original poster I do not own an xbox one console

Any solutions to this problem?
