This may be a dumb question, but any idea why you would want/need to update the firmware of these controllers?

This may not be all that helpful, but if your willing to learn (and possibly fry your controller) you may have a makerspace near where you live. If so, they would most likely have a soldering setup that you could use for a small fee.

Is there an install step that you need to run to get the expected dependencies (other than the git clone)?
