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 unbind it, you must simply change the serial number.

    I’ve done exactly as you have said to do and it just keeps my Serial Number the same without changing it. I bought my scooter off someone else, and the serial number was already input as N4GSD1111C1234 , does that mean the person who owned it before me already flashed it?

    Yeah most likely, that serial number you posted is the example one and is the default when custom firmware with compatibility fixes has been flashed.

    You may have a clone head unit that would prevent you from changing the serial number.

    Is your’s an ex-rental/non-foldable unit?
