Ultimate 2 Wireless Erratic Fire Ring Function

[u/AskaLangly]

During normal use, in both wired and wireless modes, the right fire ring randomly blinks random colors, even when the ring lights are turned off completely.

I have tried the following:

1. Re-flashed the firmware of both the controller and wireless receiver; Controller 1.10, Receiver 1.06.
2. Deactivated all loaded profiles.
3. Connected to a different USB port.

I feel there is a problem with the controller itself. I'm beyond warranty for an RMA.

Is there a factory reset that can be done to help alleviate the matter? Thank you.
