I don't work for NexDome but you should try to contact Tim , the author of the firmware. Either open an issue on the github repo ( https://github.com/nexdome/Firmware/issues ) or try emailing him may be. Have you tried contacting Nexdome directly also ?
Even though I have a Nexdome dome, I use my own controller and firmware on it, so I can't really help much more on the firmware issue.
Damn!
