I got a legally acquired snsc 2.3 aka ninebot max plus from the voi scooter company. I managed to unlock it with an arduino that simulate the GPS board by sending regular signals to the scooter with the GPS port. The scooter run well but it still has the rental firmware on it and I cannot use official segway features like flashing cfw, using Bluetooth apps, etc. Since it's not possible to do basic flashing with an st link or with ninebot iap, I want to ask how we can achieve this. Any help will be greatly appreciated. To view images REGISTER or LOGIN for full access.
