(TUT) Unlocking the Ninebot F-series (F20, F25, F30, F40) to 30 km/h (18.6 mph)

Hello everyone,
I need to change my mo F40 controller.
What should I do to activate it and change it back to f40.
THANKS

can you now tune to 30 kmh again? At first it worked because you could set the voltage to 1000, and after an SHU update that has been blocked at 700 ever since?
Model F40 E ,all updates installed,shu actually
thanks for your time
Regards tom
