When trying to connect the Android app to a Ninebot Mini (not Pro) manufactured in 2015, I am asked for a 6-digit Bluetooth password.  I have suspicions that this scooter has been used before and that someone set a password already.  I am trying to find out how to reset the scooter.  I've found the Speedyfeet video for resetting the Ninebot One, but this is the most I can find for the NBM: 若忘记改密码，可以通过将平衡车倒置，然后开机并转动车轮进行解锁，解锁后手机APP链接平衡车无需输入车辆密码 Translations mention inverting the scooter,
