Yeah, there's no way to talk to the battery conventionally once the BMS makes its ruling. USB doesn't provide power to the bird and nothing happens with a dead/inactive battery installed. Maybe this update would have made a difference for me if already installed, or maybe it was a slightly different issue being addressed.And generally, the things in the update that are not in the release notes are not bugs, but bug fixes. They don't always list them for a variety of reasons, such as (for instance) to avoid liabilities.
I'm certain that the number of bug fixes in firmware is far greater than the number of inadvertently introduced bugs. That makes updating firmware far more valuable that skipping them due to paranoia of unknown new bugs.
That said, I wouldn't imagine that any firmware update would allow a battery to charge that had already shown to be dead.

In any event I plan on opening the battery cases and using the CP2112 debug board to clear flags after charging the battery with a hobby charger. Yes, I know the risks of doing this, from the process itself, to use afterwards. If I bring them back, I'll take their history into consideration.
