Yeah, just started with those versions and im curious if they don't have some sort of motor wire, throttle wire or some other sneaky swap a roo type sh*t going on because they are a little different. If everything comes on with no errors then I would guess e everything is fine and you just might want to slow walk back over this and that until you figure it out Because if it isnt a big enough issue to throw a error as sensitive as they can be then it must be something simple. I would check with the motor wires.

From what I have read, the lyft model BMS cuts off power if it doesn't recieve an "ok" from the dash or IOT in the lyfts case. I believe you would need to flash the BMS to 134 or disconnect it entirely. If you've already done either or, I wouldn't have the slightest idea why its not running. GL

It's been liberated now. Basic rundown:

1) Flash the BMS with the full hex dump (bms134_fulldump.hex)
2) Flash the Controller with the full bin dump (esc126_fulldump.bin)
3) Flash the Dashboard with BLE555 (full_BLE555.bin)
4) Rewire the connector that runs from the dash to the controller to OEM. Blue Lyft wire replaces the Green OEM (green lyft is not used)

Ble555 just allows you to use apps that don’t yet support encryption or to not have to press the button to pair.

There’s no reason to flash BLE555 if you have a windows computer and ninebot flasher, and other apps also support the encryption on the stock max BLEs.
