My solution is as follows, turn on your PC and open the Bose update page, connect your speaker to the PC, the page will probably say your software is up to date. Next, press the following keys A, D, V, Arrow up, Arrow down. The page should then change and say it is downloading the latest software. Soon your flashing red light will change to Orange and you should hopefully get your speaker back. It worked for me, hope it works for you.
