Photon stuck in rapidly blinking cyan

Hi @guiambros -

There seems to have been several similar issues the last couple of days, not sure why. I used to be able to quickly resolve any matters running particle doctor via the CLI but the lately that too presented errors and did not resolve the problem.

After hours of trying, here is the only solution that has worked for me:

Sure, are you using OSx or Windows? I am using OSx do here is is what I did.

  1. Download the four files below form Github. Make sure to download both Part1 and Part2 for photon firmware.
  2. Install and update Particle CLI on you computer
  3. On OSx… open Terminal (or CLI in workbench)
  4. Connect device to you USB port
  5. Make sure devices is in DFU mode (flashing yellow)
  6. In terminal type: particle flash --usb and then simply drag the downloaded files into the terminal (one by one) window. It will automatically enter te file name and path. The device should remain in DFU mode after each flash, unlike Particle Doctor.
  7. Hit Enter. When done, repeat with the next file, in this order:
  • photon-system-part1@1.5.bin
  • photon-system-part2@1.5.bin
  • photon-bootloader@1.5.0+lto.bin
  • photon-tinker@1.5.0.bin

When dragging each file into terminal, you should see something like below.

After this the photon should be back to factory settings. You will have to reconnect it to your WiFi using the app or you can do this via CLI as well.

Good luck, hope this helps.

Regards,
Friedl
