Kudos James!

You held the secret to finishing this up! Pressing A, D, V, Up Arrow & Down Arrow in sequence after getting the updater going at https://btu.bose.com/ , then updating the firmware got the job done. Before doing this my power light just blinked red when trying to charge and the speaker The physical replacement was no big deal. I bought a replacement battery from amazon or ebay, I don't remember where, and instead of de-soldering the battery from the power supply board, because I suck a soldering, I cut off the old battery real short and spliced the new battery into the wires still hanging from the power supply. Lots of whining about the hardwired battery but I think I understand the decision Bose made in doing it. This little speaker booms, and the last thing they wanted was a loose battery connector rattling around. The fact that they aren't suing me for fixing it, even thought it takes a little thought and effort to do so, at least keeps them above John Deere, Tesla, etc., in my eyes.
