If an error code is generated when flashing your Ninebot, it is of course important to know what this actually means. We have therefore listed here what the respective error codes stand for and how you can fix them - if possible.

In general, all errors are displayed with two digits. Number of Long Signals = First Digit / Number of Short Signals = Second Digit.
