I'm seeing similar behavior from a Boron LTE v1.5.2. Power source = AA batteries, which ran down but were still able to keep the device running (I didn't take a voltage measurement before replacing them).
Initially the device wouldn't connect to the cloud while running my application code, so debugging info is limited to log messages, which exactly matched what user Fragma reported in the following thread:
I replaced the batteries, re-flashed application firmware, power cycled multiple times, etc., and after repeated connection failures installed the cloud debugging tool referenced above by user evk02. I let the debugging tool run for quite a while and it made multiple failed attempts to connect to the cloud (perhaps some attempts were rejected by the carrier because too many attempts were being made? -- see multiple "Resetting the modem due to the network registration timeout" messages)
Unlike evk02's device, however, mine did eventually connect on the 5th or 6th try. Then I re-flashed device OS 1.5.2, and re-installed my application firmware. All seems to be good now.
Any insights from Particle into what happened, and how to avoid it in the future? I certainly agree with evk02 that a low battery shouldn't brick an IOT device. I'll add that no additional effort besides replacing the batteries should be required in order to revive it.
Pasted below is the very long output from the cloud debug tool. To get below the character limit of this forum, several failed connection attempts after timestamp 351831 have been deleted. The successful connection cycle starts around timestamp 979536.
