Help with DRV/Speed limiter ¿E2?

[S3rch]

Hello everybody :)
I've just bought brand new a ninebot E2 and I've tried to unlock full speed, but what i can se over this forum respecting DRV Soft doesn't mach what I can see on the app.
I've already tried changing SN but with no effect as it beeps 3 times.
Any ideas what DRV 1.1.7 is?
Any help appreciated, thx
