I have had a Boron for about 6 months and built an Asset tracker with the GPS module and OLED display. The device worked great for about 4 months and I brought it back to the lab for some enhancements. I ended up not getting to it for about a month, and when I plugged it in (battery was dead), it would not connect to the LTE network and keeps flashing green. I tried to refresh the firmware through the CLI but keep getting the error “Error writing firmware: Transfer cancelled” even if I flash a simple Hello World firmware to it.
I’ve also tried re-provisioning it with the IOS app but it fails after the SIM activation. I checked the SIM on Particle Cloud and it shows as active.
I read a post that the Boron can brick if it loses power? I find that hard to believe?
