So, my a50 has been cutting out when I am talking quite frequently. I go to update the firmware, and I do the transmitter first, installs fine. I go and try the headphone firmware update, and I get "Connect your device, No device detected. Please connect the device you wish to update". Previous to that, it would run and start to install, but never finish, left it for an hour. Just sat at like 2%. Also do note that the a50 will not shut off now, and will not even begin to pair. So uh, what? This happened after the transmitter latest firmware update.
