Ninebot Max Error Code 35
"Default Vehicle Serial Number(S/N), Please replace the Master Control Board"
If your Ninebot Max is beeping or has a red wrench icon and flashes this code, read below.
If you clicked the wrong error code, go back to the Error Code Index.
This error is caused by the ESC having the default serial number of N4GEA1601C0001.
This can happen for any number of reasons but usually happens when flashing a firmware file with the serial number included.
To do that, you can follow the guide at Ninebot Max Change Serial number.
