Spark Core perpetually pulsing white

Hello, all …

One of my projects suddenly stopped working when the Spark Core at its heart suddenly couldn’t connect via WIFI. I replaced the Core with a Photon and all is well, but i’d like to find out if the Core can still be used for something else (as i’ve still 5 more of them that I received from the original Kickstarter campaign). I tried to do a factory reset of said Core, but it’s been pulsing white for over a day now. Is it dead / defective? Can it be saved? Will I experience this issue with the others?



  • place in dfu mode
  • run particle flash --usb cc3000
  • wait for device to blink magenta and revert to blinking yellow
  • particle flash --usb tinker
  • pray that it works
