STLink Ninebot Max G30 Gen 2 ESC
In the case of a bricked ESC/Controller/Control Board, STLinking can save the controller from needing to be replaced in some instances.
For this process, you will need:
- Windows computer
- STLink (Decent quality clones will work)
- Tools to disassemble the scooter and access the parts
- Dupont male/female jumper cables
This process can be dangerous if done incorrectly so take caution when performing these steps and make sure you use a computer you are comfortable possibly destroying.
If you short a battery line you could end up blowing up your STLink, Computer, and more or even causing a fire.
For the Ninebot ESX Series/SNSC 1.0, use the guide at: STLink Ninebot ESX ESC.
