Failed/Interrupted firmware update

I have an xbox elite controller and unfortunately, mid updating the firmware on pc, had the xbox accessories app crash and now is not recognized by the computer at all (even wired). I´ve tried a number of things to get it to at least be recognized in any way, even getting a microsoft wireless controller adapter, but nothing works despite the controller turning on and having power.

Any way at all to flush the firmware and reinstall a clean one?

Do you have a Xbox as well or just pc? If you have a Xbox try updating through that. If not do you know anyone with a Xbox?
