Hello! Sorry for the translation. I was able to set the speed of my now buying F40E. My maximum speed is 34km / h. But the dashboard still shows only 25km / h. Phone gps 34km / h. Is there a solution for this?
Thanks!

Ble 3.0.7
Drv 5.3.4
Bms 0.0.0

I have unfortunately upgraded to DRV 5.6.9 and it really sucks.

I'm trying to downgrade it to 5.4.9 or another earlier version using IAP and Ninebot Flasher, however both these apps say 'bad file' when trying to select the drv549.bin.enc file.

What's the recommended way of downgrading firmware on F series scooters with Windows?

Hi,

any luck with downgrading firmware?? My updated to 5.7.7 and I am stuck with 20km/h

PLEASE HELP!!! PLEASE HACK MY F40

The same thing is with me too, but with the latest firmware!
Ble 3.0.7
Drv 5.7.7
Bms 0.0.0

I have F40E and I just put it to F40 - global in this app.
It shows 25-27kmh but it goes much faster. Some guy on bicycle behind me sad that we were going around 35km/h.
And I don't have any accelarate issues that people complain about it or starting from full stop.
BUT, the accelaration on D mode is not like on regular D, it is more like on S. So I think that someting is wrong here in the software.
The route from home to work is 11km and in "locked" mode battery is depleted for around 34%, in "unlocked" mode it goes down for few more %, to around 44%. So, usage is around 10% more.

best regards!

According to reddit, you can replace the motor controller. I think it will be difficult to find the JTAG pins as the the controller is covered in black resin.

JTAG pins is on easy point at the controller board. Problem for me is what i have to do without f-series full dump file?

Is it possible to dump the firmware from an existing controller?
Is the format of the firmware file different when flashing via JTAG than when flasing via Bluetooth? The apps are able to download firmwares from somewhere at least.

No. It is impossible for me :)
