Boron Connection Issues, 2.0.1 modem non-responsive

I’ve already submitted a ticket but a device that had been publishing data out in the field for days is now unabled to connect (likely after a battery running out of power). The LTE Boron is blinking green and after running the clouddebug tool I get logs that seem to indicate a bricked modem (I’ll post these as a comment). From what I’ve seen on this forum, this was a common failure about a year ago but was supposedly resolved. So my questions are as follows:

  1. Can somone confirm from logs that I’ve correctly identified the issue?
  2. Is anyone else seeing this issue with Device OS 2.0.1?
  3. Is there a way to recover a device’s modem in this state?
  4. How can I prevent this from happening to devices out in the field?

Hi @rkast4321 - can you please open a support ticket that references the device’s Serial Number so we can take a closer look? Can you also please provide the complete log (at least 10 minutes, however redundant) from cloud debug?

Can you also please note whether or not you are using a 3rd Party SIM?

A ticket has already been submitted with the device ID, ticket # is 101283. It is using the built in SIM card, so not 3rd party. And I’ll attach logs momentarily.
