I have a Bose Solo bought in 2012 when I insert a flash drive DOS FAT 32 format for update I get a flashing amber light for a few seconds. Then flashing red light. That will not go away until I unplug power.

Thank you for posting. Is there any other files on the USB drive? Instead of performing a Quick Format, can you do a Full Format of the USB and try again?
Let me know if this helps.
