When you buy a new board (see here if you want one) and fit it, you will be met with no stabilisation when you boot it up.
Do not worry, email us and let us know your order number and follow the below instructions:
1. Fit the new board
2. Power up the unit once all built back up
3. Connect via the Ninebot App to the new board
4. Go to the Settings section
5. Select 'Set Serial Number'
6. In the target fields enter YOUR serial number (Printed on the ninebot or get it from the box or instruction manual that was enclosed).
7. Once filled in screen shot that screen and send it over to us via email.
8. We will then get an unlock code from Ninebot and reply back with it, it can take 1-4 working days.
Hope this helps!
