Unable to launch NetduinoDeploy on Mac, device partially bricked

The Mac app opens and immediately closes. I see this in the Console.app

Unhandled Exception:

I was able to previously launch it, but I noticed that my network settings were no longer working so I tried to re-install the firmware too. That failed with a similar -9 code. When I clicked the “Save Settings” at the top of the app, it crashed and now it no longer opens. Any tips? I can’t do anything with the board at the moment.

Is there anything I can do to “factory reset” this? I found some old forums posts from 2015 but I want to get updated information if applicable. If I have to re-flash this, that would be fine.

I was able to resolve this using Windows and the flashing directions linked in this post.

So far, so good. :slight_smile:
