Thank you for testing so quickly.

Nice, as I had hoped.

That's expected with the current source tree. We're in the process of
converting the chip unlock code to a new interface, and right now only a
very small number of chips has the necessary unlock functionality.

Yay. Our guess worked out just fine.

I guess we can mark the MCP61 as partially supported now. The failing
