I installed Tasmota firmware on my Sonoff Zigbee bridge over 2 years ago, and it worked fine. I found that my Tasmota devices didn’t work with my new installation of HA, because their firmware was too old. I updated the firmware on my devices and all worked OK. I then thought that I ought to also update the firmware on the Zigbee bridge, so I just went ahead and updated it with the same firmware as I used on the devices and it is now not working (I know - I shouldn’t have ‘fixed’ it because it wasn’t broken!).
How do I recover my Zigbee bridge to its previous working state, please?
