Not sure what happened but I didn’t change any of the Electronics I had plugged in at all. I merely tried to update the application I had written. I’m not sure if there was some loose connection or something but now my spark core won’t turn on at all. When powered up the small blue LED flashes once…

Single Blue Flash = Dead core?

Sorry I'm out running all over Singapore and can't post a proper guide but look at this

Spark_4 is the latest firmware
