WH67 firmware update failed and bricked my headset!

I cannot get support to respond, I've opened two tickets and I'm about to return this headset.

I plugged it in, the speakerphone worked just fine. The headset didn't but I attributed it to a low battery.

I installed the Yealink USB Connect and it immediately prompt for a firmware update. I clicked on install, it ran, failed and the display just keeps displaying firmware update, do not power down. This went on over night.

I unplugged it, plugged it back in and it give me the same message.

Is there a firmware recovery process?

Thanks,
