There is a flashing issue with the ZBT-2. The latest update tries to flash the ZBT-2 running EmberZNet Zigbee from 7.4.4.6 to 7.5.1.0,. The update fails and Zigbee is no longer operational. Some people report similar issues with the ZBT-2 running Thread.
Any suggestions how to proceed are welcome. Just let me know if you need additional information.

ZBT-2 breaks with update 7.5.1.0

Look at this solution by @soashen in the above community entry.

My zbt2 failed, because I forgot to stop zigbee2mqtt.

Then it failed again, even after restarting HAOS (with ztm disabled on startup).

Finally, I did a full power off, un/replugged ztb2 usb, powered back up haos, and finally the fw was able to update.

Restarted z2m, and everything seems to be back up again.

TLDR;

if you are using z2m, temporarily stop and disable on startup
do a full power off, then restart
when haos/HA is full running, re-try the fw update
My skyconnect/thread mode updated without issue (before I attempted zbt2)

good luck

Alternatively you can re flash the adapter through the web/serial util
