I had this issue but holding down power and.volume did nothing unfortunately. Eventually the fix required me to plug in the speaker to charge, after 27 seconds the light stopped flashing, unplug-replug, 27 seconds the light went out. I repeated this maybe 17 or 18 times and eventually the speaker must've had enough charge in it to the beginning charging normally. The remote on feature definitely isn't a great idea if you don't use the speaker regularly.
