Hi again :)
My Ninebot9 blinks number 31. And the image of the tool and the stroller.
What does that mean?

You may get better replies in one of the two wheeled subforums, but a quick search on the internet says that the ptr error code 31 means: 

There is a problem about the connection between control and driver or chip problem


There can be any lose connection

in between the mainframe and

handle bar OR in between the

handle bar and dashboard
