upload Zigbee firmware using Tasmota 9.2.0 failed

[manrot05]

Hi
Problem: I can not flash the zigbee chip with the firmware fw_SonoffZigbeeBridge_ezsp

Here the steps I did: (on a windows10 machine)

• I flashed Sonoff bridge with tasmota-zbbridge.bin using tasmotizer 1.2. to version 9.2.0
• connected bridge to my WiFi, gave it fixed IP-address
• UI is showing "Tasmota 9.2.0 by Theo Arends"
• downloaded ncp-uart-sw_6.7.6_115200.ota file from Github
• I choose from menu 'Firmware Upgrade'
• Upload started ... => Upload transfer ... => after a while I get error msg: Upload Failed Upload aborted

When I look in console screen I see these messages:
23:33:07 UPL: File ncp-uart-sw_6.7.6_115200.ota ...
23:33:11 UPL: Transfer 190272 bytes
23:33:11 UPL: Successful 190272 bytes

What did I do wrong? Can anyone help me?

Ensure that you have Module 75 activated to upload EZSP firmare, "Sonoff ZbBridge Module" at the top of the web UI.

ok I am a newbie and just followed some instructions found on youtube. Were the same action was done and It magically worked

how do I activate 'module 75'

Do not assume that some old YouTube video is a good guide when we have the actual documentation online for the Tasmota on the ZbBridge. You can set/check the module using the Module command in the console, or via configure module.

Ok, I should have linked the Youtube video in my response, since it is only 1 day old.
Sonoff Zigbee Bridge | How to flash with Tasmota and setup in Home Assistant with ZHA

I checked your link to blackadder ZbBridge and I can not see any difference from what I did, or what the YT video showed
Flash ESP8266 was no problem.

Flash Zigbee module ends with failure in my case.

• Go to Firmware Upgrade and next to “Upgrade by file upload” use the Choose File button and select Zigbee module firmware you downloaded (ncp-uart-sw_6.7.8_115200.ota).
• Click on Start upgrade, be patient and wait for a few minutes until flashing is complete. Once it is done, Tasmota will reboot. If the flash was successful the console will show Zigbee2Tasmota starting:
• .... ZIG: Zigbee started

It says: "Follow further instructions depending on your chosen method."
and then additional instructions are given, but only after flashing the firmware.
And that part ended in error in my case. I do not see zigbee started

Regarding module 75 I checked via configure module and it was already selected, but I reselected it and zbbridge was restarted, => repeated the steps ended in the same failure

I added some screenshots, maybe I am still missing something.

I have no idea how to solve this problem
I tried with 4 different kind of flash firmware versions
8.5.1
9.1
9.2.0.3
9.2.0

but still upload failed

followed the steps on https://zigbee.blakadder.com/Sonoff_ZBBridge.html
and added the intructions 'module 75'

please help?
