When buying a Ninebot Max/SNSC 2.0/G30 used, the previous owner may have forgotten to unbind the scooter from their account.
A scooter bound to a different account prevents the new owner from changing settings with the Official Ninebot App.
Settings, units, and more are not able to be changed until the vehicle can be bound.
The account bind is based on the serial number of the ESC.
To fix it, you must simply change the serial number.
Open IAP on a Windows Computer with BLE, and find your device by pressing “scan now”.
Select your device from the list and press “Connect” under “Start Scan”.
You will likely be prompted to press the power/headlight button after connecting, and it will only pair if you are not in charging mode. make sure the charger is disconnected.
From here, open the tools menu.
Press “Read SN”, and make note of your current SN.
Your serial number should be output next to “Output”.
Press “Change SN”, and change the last four digits, or change the whole number.
If the app still says “Vehicle bound by xxxxxx”, you may need to change the last 4 digits again.
