Sonoff Zigbee 8266 - Wrong Tasmota Firmware

Hi,

in my Sonoff Zigbee Gateway (ESP8266) I flashed the wrong software (the simple Tasmota 9.3.1) and it has of course no Zigbee functionality.

I tried to flash the right one (tasmota-zbbridge.bin) but it fails.

How can I recover my ZigBee Sonoff?

Thank you for your help!

Why is it failing? Is it out of memory? If so flash with minimal.gz firmware then flash with the zigbee firmware .gz version disclaimer I have no experience of zigbee sonoff .but this is how you flash tasmota on esp8266 boards.

I tried the way you described. With the minimal release first and then with the zigbeebridge version. I had several problems. With the Tasmotizer I have often a “timed out waiting for packet” error, but the flash of the minimal release works always.
One time I could flash without errors the zigbeebridge version, but it was impossible to reach the board via WiFi (board not found with a IP scanner and no Tasmota access point).

Now I want to try with another FTDI adapter.

Try asking on here

Or use the sonoff dongle 3.0.

So, now it works!
I repeated several times the identical procedure and suddenly it worked! Don’t ask me why, but this is very strange! I guess this is a timing problem with the FTDI interface.

Thank you!
