Boron Flashing Red SOS - Blink 10 - Cannot Recover

Can a Boron that was the gateway for a mesh network be once again configured as such without using the iPhone app? Can it be done via CLI? If so how?

My boron was the gateway for a mesh network then had to be recovered from red flashing SOS. From listening mode I added it back with the iPHone app making it part of the orignal network…but the Xenon cant see it and its not a gateway here --> https://console.particle.io/networks/sevaomada
