After upgrading to 25.11, my SkyConnect dongle stopped working, and ZHA integration failed. My SkyConnect had the Multiprotocol firmware installed and multiprotocol enabled, which I’ve now disabled.
I’ve followed all the advice to fix it, but now I’m stuck in a circular loop as the automatic firmware update doesn’t recognise the SkyConnect dongle.
Current state: HA to reporting a repair task:
Zigbee adapter with multiprotocol firmware detected
Error · Reported by zha
Your Zigbee adapter was previously used with multiprotocol (Zigbee and Thread) and still has multiprotocol firmware installed: (CPC).
To run your adapter exclusively with ZHA, you need to install the Zigbee firmware:
* Go to Settings > System > Hardware, select the device and select Configure.
* Select the 'Migrate Zigbee to a new adapter' option and follow the instructions.
When I go to the configuration page, the only option I have is to enable Multiprotocol
I have installed the Silicon Labs Flasher add-on and tried to use it to update the dongle; however, it doesn’t recognise it, reporting this warning:

There is only one device listed in the configuration and this is selected.
I did see that someone managed to solve this by performing a manual firmware update via the https://support.nabucasa.com/hc/en-us/articles/26124447269917-Updating-firmware-for-Connect-ZBT-1. However, it appears that this option has been removed now and HA now uses automatic firmware update.
Is there a step I’m missing, or is there a method to manually update the firmware?
Gary.
