In this video, I am swapping the heads of the scooter to be able to hack the scooter with the BLE157. If someone is on warranty and doesn't want to solder...

While it is technically possible to flash the BMS, there is no actual need to do so. I simply wanted to demonstrate that the capability exists, but it is not required for the current situation.
For users with a BMS version higher than 1000, it is important to note that downgrading the BMS will lead to brick, don"t do this!!!
