Hi there, not sure if this is the right place to ask. I tried to upgrade my ua3 to 1.07 firmware and the procedure worked, but after that my ua3 is not recognised anymore. When connected (using usb audio player pro), my Android phone asks me if I want to connect to Comtrue-inc firmware update device, I say yes, but the no sound come off my earphones. When connected to the pc, the device is not recognised at all. I tried to upgrade to 1.09 firmware, but when asked to connectbthe device, nothing happens, no blinking light on the dongle.
Is there anyway to reset the device?
