Questions answered in these manuals
Why does the device show an error or become unavailable?
Because the USB driver is not installed or has been blocked by antivirus software, causing the yellow LED to flash rapidly.
Why does firmware refresh fail?
It is usually caused by using an external USB hub; connect the programmer directly to a computer USB port.
What should I do if the device shows ‘Device unavailable or error’?
Re‑install the USB driver and ensure antivirus or firewall software is not blocking it.
