Same problem here. Tried to just reload the Firmware several times via USB… kept getting an error 010 at the end. Was a bit skeptical of above so I initially just unplugged everything from the mother board with the exception of not removing it and therefore not disconnecting it from the board on the side, and then re-assembled. Booted up and again tried to reload firmware several times via USB. Same error at end. So then I removed the board and baked at 390 for 15 minutes per the above, AFTER removing the one piece highlighted. Let it cool, reattached everything. Then tried to update the Firmware via network. It finished quickly, but still no sound. Lastly, I tried again with the USB method and SUCCESS!! Everything is working fine! very very strange… not sure which step fixed it. a) removing the board from side board (complete disconnection), b) baking, c) trying the network method first, but ITS WORKING!!! Cheers.
