After failed my firmware update (download can t finish, try again or like this error)
and try and try again, my CP540 doesn t power on.
Anyone have an idea or where can i send it for repair?
I know this is an old topic, but I successfully recovered from exactly the same problem. See my post here: https://timingguys.com/topic/5...8#597764686490562328
In short, you must use a real serial port on an old PC, not a USB-RS232 adaptor.
