Flashing clean light on the Braava M6

Hi, My M6 only response is while it is docked the clean button just rapidly flashes increments of 3, but only when docked.

What I have seen through the troublshooting is that it is updating, but it has been doing this well over a week now. I called customer service and they said that it was the battery and it needed replaced. I purchased an aftermarket battery on ebay but when I installed it the exact same flashing cleaning light while docked. Ive seen this problem being mentioned a few times on forums but have yet to see a solution solved for the issue. Any advice?? thanks!
