My Boron 2G/3G was working fine, but for unknown reasons now only flashes green. I’m using a 3rd party sim and credit is good. I also have many other devices working fine on the same 3rd party sims.
Using the CLI, I’ve done a “particle update” in DFU mode. I’ve also reset the 3rd party sim credentials using the instructions here, which was followed by running “particle flash --usb tinker” in DFU mode. All programs seem to install ok, but I still cannot get the device into safe mode. I’ve changed antennas and 3rd party sims to no avail. I’ve run out of ideas. Any help appreciated?
Hi there!
I would suggest going through the steps highlighted here: https://support.particle.io/hc/en-us/articles/360044518213-Troubleshooting-Cellular-Connectivity
The cloud debug tool will help you see what is happening between the device and the cellular tower.
I’ve run the cloud debug tool - thanks for the suggestion! I"m not sure how to interpret the output but it does seem that my boron is in a bad way as it cannot even report its basic details like IMEA, ICCID etc. Any idea on how to proceed from here?
Output below:
clouddebug: press letter corresponding to the command
a - enter APN for 3rd-party SIM card
k - set keep-alive value
c - show carriers at this location
p - select MNO profile
t - run normal tests (occurs automatically after 10 seconds)
or tap the MODE button once to show carriers
enter APN:
APN set to telstra.wap

Just to add: “particle identify” fails to find a serial port which is strange because any other command in the CLI seems to be executed without error.
Serial err: Error: Opening COM31: Access denied
Serial problems, please reconnect the device.
.And closing Terra Term I get “Serial timed out”
That is indicative of a dead modem - No response from NCP. Please create a ticket at support.particle.io so we can organise a replacement for you.
Thanks for your help and diagnosis!
