When buying a Ninebot ESX(ES1, ES2, ES3, or ES4) used, sometimes the previous owner forgets to unbind the scooter from their account.
If you are using a Ninebot Max/G30/SNSC 2.0, use this tutorial. Functionally they are the same but the serial numbers are different.
If you are instead trying to unbind a device from Your Account even if you don’t have physical access to it, use this tutorial.
A scooter bound to a different account prevents the new owner from making changes using the 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”.
If you are on BLE > 1.0.7 (i.e. 1.0.9) you will be prompted to “Press the power button to pair”.
The device will not pair until you press the button you use to power on the scooter/change mode/enable the headlight. Short press it and it should connect.
From here, open the tools menu
Press “Read SN”, and make a note of your current SN.
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 it again.
