Boron LTE Setup - Error while accessing modem?

Hi there @dwstang

We are aware of this issue and are addressing it in our upcoming release v0.9.1. The issue is actually a software one. More information can be found at Developer Support Update | Boron Pausing and Setup Concerns in the second part of the topic: Borons not completing setup flow, reporting empty ICCID and IMEI

The best option at this point will be to wait and go ahead and flash v0.9.1 as soon as it is available.
