How do I reinstall the mender stuff to Raspberry Pi using "Getting Started" on a decommissioned device?

The device is a raspberrypi3 or specifically a raspberrypi0 wireless. I deleted:


with sudo rm -r and that seemed to go through and I decomissioned the device on the Dashboard of Mender. Now when I re-run the setup script on the Pi Getting Started guide button, no device shows up under Any or Pending devices…

What can I do?

Reinstalled OS that’s how
