Picked up a used V2 hub on eBay to use for beta firmware testing separate from my “production firmware” dev hub. It was still in the Hub/Things combo box and didn’t appear that it was ever used.
The firmware progression it updated thru was quite fun!

I might have missed a couple in there but it was pretty impressive. After many cycles of blue->green->magenta (sometimes needing a reboot command when sitting at idle green between updates) the hub is running current firmware. ZigBee and Zwave radio firmware got updated along the way too.
