Ninebot Max Error Code 51
"Controller and dashboard match failure"
The app is unsure what this error code means as it's usually a rental only error code.
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.
Currently, I have not experienced this error so I am not sure what causes it.
Update all parts to "proper firmware".
Restart the scooter.
