New controller firmware? I am not on Alpha

I am having the exact same issue. The new firmware update made my controller super laggy. I am trying to revert it back to the old firmware but it will not let me do this.

Hey, I have this same issue with my Elite Series 2. Also, if I press the guide button it shuts the controller off and I am unable to turn it on without plugging it in again. This just started happening after I updated the firmware to the new version. The issue now persists after I rolled back to the old firmware version. The new firmware update seems to be breaking something in the controller. I hope a fix is found soon because my out of warranty controller is now effectively a $180 paper weight.

I am having the same problem. Each time I try to update a controller, it fails. My controllers have the 1.1.2228.0 firmware. Can anyone confirm that this is the latest?

I even pulled 2 brand new controllers out of the box and flashed them to the same firmware version. Same problem. Interestingly enough, I just bought it on sale just yesterday as well.

If your console is in the Insider Preview (Alpha or Alpha Skip ahead) try to disconnect all controllers and headsets, and only connect one controller and one headset.

Have you tried to delete the "old" controller from your Windows PC in the Bluetooth device section and then rediscover it. The firmware update may present the controller as a new device to Windows - meaning although it is still the same physical device -
it has changed internally based on the new firmware to look like a new controller to Windows.

As far as I know, there is no way to roll back the firmware update on the controller.
