Photon not flashing correctly, or always flashing with tinker

Troubleshooting
36

Thanks for the update - flashing cyan at high speed indicates a problem with the keys.

We will save the current key and flash new keys to the device using particle-cli, so please install that first if not already done.

  1. Put your device in DFU mode.

  2. Save the current key (for diagnostics/troubleshooting)

particle keys save photon.key

Please send the key to me.

  1. Then create new keys:
particle keys new
particle keys load device.pem
particle keys send <device_id> device.pub.pem

The last step may not work for a device that you’ve not claimed. In which case PM me with your device_id and I will register the key.
