Hobbyist: no signal after aborted TC358743 experiment

After setting up the hobbyist kit version of your device, I learned that TC358743 based capture cards reduce the blur of usb based ones. I thought I might order a compatible card and saw the instructions on enabling support. I though I might as well see what happens trying to enable it (https://github.com/tiny-pilot/tinypilot/wiki/Installation-Options#example-tc358743-hdmi-to-csi-capture-chip). I used the /opt update scripts since I have the pro software. I was expecting something along the lines of enabling a kernel module - it would be available for later. Instead I watched it fail. That was fine, I thought. I removed that line from settings.yml and re-initiated the update, but now I have no signal for video connecting to a machine that worked out of the box. I do have keyboard and mouse support. I seems the aborted experiment has left something that is interfering with my ability to connect using the hdmi dongle. Do I need to reset the EDID? How do I revert to "factory settings"?
