You can try
particle flash --usb tinker -v
particle update -v
particle flash --usb tinker -v
Additionally to some possible issue with the current firmware state of your device another reason for that issue could be that your MODE/SETUP button got stuck in the connected state or you have something holding the MD pin low.
