Do you have physical access to your device? If so, try to use one of the exe or spk files from here to update your device [https://mangoh.io/mangoh-yellow-resources-software](https://mangoh.io/mangoh-yellow-resources-software)

On my device, I don’t see an option to deploy firmware from Octave, so I’m not totally sure how you did what you did, but this might help you to get access to those sensors again.

Is it possible you somehow installed the mangOH Red firmware on the mangOH Yellow? What apps are installed on your system?
