Thanks for pointing that out. I found Ublox modem firmware update with very specific directions. Fortunately, I’m in an off season until March, so I can sit on this a while longer and see if Particle finds a solution. I’ve been 0 for 7 in bringing devices that started flashing green to life with an upgrade to 1.4.4 using “particle update” in the CLI. Unfortunately, i’m not sure the root cause is addressed and it’s just a matter of time before my other deices fall into the same state.
