S1 Pro Service Port Not Working - Early 2018 Version
I purchased one of the early versions of the Bose S1 Pro. Documentation indicates you need to update the firmware using the USB cable connected to the service port. I also bought a 2nd S1 Pro a year later. The 2nd S1 Pro I can connect to my MacBook and run the update successfully. The original S1 does not recognize it's connected. Same cable, computer and approach. Tried removing battery, charging fully, different Windows computer with the same issue. The updater does not recognize it's connected to the service port. Please help! I'm starting to think the 1st versions had different hardware or firmware and it's a hardware issue.
