Hi,

30kmh unlock is available for DxxE series with M365 DownG app. After connecting the app to the scooter change the serial number in the settings from N8GJ... to N8GK...

Works great for me. Probably should delete the official app before doing this though.

Has anyone else tried this method?

Still no hacks ? :( In my country Ninebot APP is garabage, as there is even no cruise control :( I wait hack for D38E to... when I bought the d38, I thought that it was the same f40 only slightly updated, only a different brake and chamber wheels ... I was sure that it would be immediately unlocked...
