Error after Update to ncp-uart-hw-v7.4.2.0-zbdonglee-230400.gbl

Hi there.

I'm not really an expert in this and just tried updating my ZBDongle-E to a 7.4+ version to be able to use it with HomeAssistant and Zigbee2MQTT.
I was previously on MultiPAN (which I didn't really need). I've downloaded the ncp-uart-hw-v7.4.2.0-zbdonglee-230400.gbl which after reading this thread may have been a fault and I should probably have picked the 115200.

Anyway, the flashing was working fine according to the webflasher. However, the device never got back.
So I've installed python, pip and finally the universal-silabs-flasher (under windows) and seem to have the flasher working.
I've tried now to "probe" as well as flash a new firmware. Neither work and throw the same error:

I'm running Powershell as Admin, so the Access issue shouldn't come from Windows (I suppose?).
Does anyone have an idea how to resolve this issue? I'd really appreciate any help!

Thank you and kind regards
André

PS: I've attached the flashlog from the Webflasher.

You need to specify speed 230400 when flashing

You need to specify speed 230400 when flashing

Sorry can you explain a little bit further? I’ve tried flashing with the parameter --bootloader-baudrate 115200. so I guess I’m using 230400 instead?

[Nerivec]

You might want to stay with 115200 firmware for Dongle-E. It's the most tested one.

[mamrai1]

Yes, use parameter --bootloader-baudrate 230400 and flash the 115200 firmware

[andre1808]

Thank you. I will try tomorrow and let you know the result

[darkxst]

Yes, use parameter --bootloader-baudrate 230400 and flash the 115200 firmware

This should be

--ezsp-baudrate 230400

[darkxst]

web flasher will now probe 230400.

[andre1808]

web flasher will now probe 230400.

Thank you so much. I’ve used the webflasher and it worked immediately!
Now I just need to make it work with HA again - but that’s not your business I guess :)

thanks again for your great support (to all :))

[darkxst]

Good to hear its sorted now, will close this issue.
