Firmware Upgrade fail MacOS

Open Box, plug in to MacMini, Keyboard boots and looks alive.

I restarted with SHiFT+PROG depressed to switch into Firmware Upgrade

Firmware Updater 1.13 loads up
Connects to Keyboard, declares v1.13 installed -only option in Upgrade

Upgrade program Fails/aborts

Keyboard boots in Upgrade mode, no keyboard

Is there an Exit Upgrade Protocol so i can unbrick the Mini Plus?

Thanks for Any Help!

I was able to Complete the Firmware Updater program - and get OUT of Upgrade mode after full system restart

If I am DevOps, I would have a Out of Upgrade mode key sequence to Restore System Ops. - just sayin…
