Good luck.
I had to reimage through serial/USB then the Raspi OS properly downloaded the current image. Thanks for the links getting me in the right neighborhood.
Anytime! Hopefully this is a resource for future users.
I mean this in the nicest way possible, but if this threw you for a loop, you’re in for a world of hurt once you get the software up and running. It’s not rocket science, but learning to administer any Linux server will take a little time. I’m sure it’s not bricked. Consider this an opportunity to learn how to write a new disk image and interact with your new server through the console.
I had previously run HA on a Raspberry Pi with Z-Wave, Sonoff, and some Hue, years and years ago. After searching for a Zigbee (since that seems to be the current standard and I'm starting over) adaptor that was HA compatible, I saw they offered their own hardware. After 18 months of waiting, I figured it would "just work." Anyway, I reimaged over USB-C and it's working. I'll definitely do a backup before doing my first software update now that I have something to lose.
You can RMA it.
