Thanks for the reply! It’s rapidly blinking white, not breathing. I have tried putting it in safe mode and flashing by holding down the setup and reset buttons, then letting go of the reset button until magenta comes up --which it does immediately, or I can wait for it to cycle again. It doesn’t stay breathing magenta though and just goes back to rapid white.
I followed this: https://docs.particle.io/guide/getting-started/modes/electron/
I don’t remember ever setting it to SYSTEM_MODE(MANUAL), is there a way to revert this? The firmware upgrade does not work at all and I cannot see my electron from the list of devices.
Verified that the U270 version I have should work with Asia here: Electron + Particle SIM + U260/U270 confusion in AU = unable to activate
