My Dyson V15 battery locked up after I used it until it completely died. To fix it, I opened the pack and manually balanced all the cells to the exact same voltage level, but the BMS is still locked.

Is there any way to clear this lockout flag while keeping the original firmware intact?
If there is no way to keep the original firmware, can I flash an aftermarket firmware?
Thanks for any help!
