can you detail what you did to get the error?
did you swap out the handle bar/throttle/dash/dashboard from a donor lime/jump to a bird es2 or es4?
swap in a oem or non-oem dashboard?
flash custom rom?
I used an oem dashboard with a Lime control board inside the scooter
I had the error  and  with the message « sent retry » in front of the error code
Therefore I tried to flash an OEM control board with default serial number. I had the same error
I also tried to swap the dashboard and the control board of my Lime scooter to OEM and try to change the serial number and get the scooter as GuilleMT witnessed but it fails
When I enter the new SN in both fields of the SN changing option on the ninebot app, the scooter disconnect itself, tries to apply the new SN in it but then it bips again and when I check again the installed SN, the default one remains
Just like if the control board was write-protected
If it is, that would also explain why I can’t flash the scooter through the EsdownG app
