Problems with Zigbee on Skycard/zbt-1

HA Novice ! & struggling. Trying to get zigbee devices on HA I have a Skycard ZBT-1 When I try & add Zigbee Home Automation it tells me " Your device is running the wrong firmware and cannot be used with ZHA until the correct firmware is installed. A repair has been created with more information and instructions for how to fix this."
If I select Vigbee error message says “Your Zigbee radio was previously used with multiprotocol (Zigbee and Thread) and still has multiprotocol firmware installed: (SPINEL). To run your radio exclusively with ZHA, you need to install Zigbee firmware. Follow your Zigbee radio manufacturer’s instructions for how to do this.”
but I cant find a fix

I think I may have inadvertently installed called Thread (dont know what that is)

Also have a standalone SONOFF Bridge Pro, that works on my phone but won’t install on HA.

Running HA on Green ZBT-1 is a USB dongle

HELP !!!
