After typing below message I went hunting for my remote, which I never use. The 'bluetooth power' button seemed intriguing, so I pressed it. The functionality works now. :D I tried unplugging it for a good 10+ minutes on your suggestion and it made no difference. I also unpaired my phone (iPhone X) and re-paired it. Still behaves the same. I am not sure how to display the currently-installed firmware version. I tried holding down the source and then the power key for several seconds but the only thing it did was mute the speaker. I installed three files - as far as I can tell the installation was successful for each. I installed each file separately and wiped the USB stick between each one. I did the installation in this order: HMS-K450WWB-1005.0.ROM HMS-K450WWM-1006.0.ssp HMS-K450WWMW-T0151.ssp

With the factory firmware, my soundbar would turn on from standby mode when a device such as my iPhone attempted to connect via bluetooth, and automatically switch to bluetooth mode and the connection would be made. Since updating to the latest firmware, if I attempt to connect while the soundbar is in standby mode, the connection will fail. I can only connect if I power on the soundbar and put it into bluetooth mode first. Is there anyway to regain this functionality?
