I think this shipped about April 20, 2015 so it's well inside warranty. Let them fix or replace.
Screen on soundbar shows this message, pressing the "F" button on the soundbar only cycles between BT READY and USB (remote control doesnt work at all). My TV (42LB700V-ZG) can find the soundbar when searching on sound sync but cannot connect (no LG-TV option on soundbar). Tried connecting my iphone through the bluetooth but it came up with "LG LAS350B (8c) device not supported.
A search of the web has bought up nothing about the "Emergency update mode"
