Stuck in update/reboot loop after flash

I’m having trouble getting my spark core to flash correctly. I can use the CLI to flash back to tinker, but when I try to flash an application that I’ve used in the past, it doesn’t work and seems to get stuck in reboot loop. This happens when I flash using USB or OTA.

After doing the magenta update it will go

  1. flashing green
  2. lashing cyan
  3. short yellow a few times,
  4. back to flashing cyan
  5. back to flash green and loop this sequence again

I saw this yesterday using SEMI_AUTOMATIC mode. Is your old app using that?

Can you try with 0.4.7 to see if it works?
