[Old Spark core] Unable to setup device

Troubleshooting
3

Just in case anyone else has this issue, these are the steps I followed:

  1. Put the Core into DFU mode.

  2. Install the DFU-Driver (Tutorial: Installing DFU-Driver on Windows [24 Feb 2015]). I didn’t add it to my Windows path

  3. Flash the firmware file

  4. Redo “particle setup”
