Upon choosing to upgrade BluOS on my NAD C388 amplifier via my Android phone BluOS app, I'm now also experiencing the same behaviour as described here. The amplifier displays the message "Executing BluOS Upgrade" for about a minute and then shuts down. I'm not able to select the BluOS Reboot or BluOS Reset options in the amplifier BluOS Setup menu. Any suggestions on how I may be able to resolve this issue? Would appreciate your prompt response to this since being unable to use our amplifier is significantly impacting us.
