eARC update bricked my HW-Q80R - Any help appreciated

[dtbrown]

So today noticed eARC on soundbar when turned on.  Also noticed no audio and my google TV via HDMI 1 wasn't being recognized.  I did some trouble shooting and noticed won't connect to WIFI or BT either.  Also my TV won't recognize the ARC signal.  Did hard reset with holding - and + volume along with hard power reset and nothing.   So downloaded update VER 1012.6 to USB and sound bar won't recognize the USB or the file.  I tried putting update in root directory of the USB and even tried in the root main folder and still won't recognize the update.  

At this point done more than samsung support even suggested and submit an inquiry for service.  I'm just out of warranty by a month so hoping Samsung will recognize their update bricked my soundbar.  Any other suggestions are appreciated.

Had a similar problem with my HW- Q80R. Didnt update but eventually after experimenting I seemed to have a stable eARC connection.

Do you recall what you try that worked? As of now I cannot get any volume output or volume control. The only thing that works is switching between sources and settings, and it will power on and off via Arc.

I think if I recall I reset the TV and the soundbar and started from scratch. Sorry.
