Just got a ZBT-2 today and went through the onboarding flow and chose to set it up as a thread device.

Unfortunately, seems to have failed and now I can't get any response from the device.

Happy to open it up and reflash it, just not sure how / where to find the tools.

Connection failed
The running firmware could not be detected.

Make sure the USB port works and if you are using a USB extension cable, make sure the cable can transfer data. Unplug the Home Assistant Connect ZBT-2 and plug it back in to reset and try again.

It sees it, it starts to connect to it, then it just kinda....dies?

have you tried a different cable?

I have, I actually think this might be defective hardware. Every 5 seconds-ish appears to "reboot" itself. I can watch the device disappear and reappear in dmesg

I have a zbt-2 for zigbee and a zwa-2 (both flawless, btw). Tried with their cables and their usb ports and still same problem so really can only believe the hardware itself is having an issue that's causing the "flapping" behavior.
