you will only be helped by the firmware using ST link
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.

It seems the older firmware files are available here. Or maybe these are not the full dumps?

I tried to unlock the F30 to 30kmh by using the app, I realized well it wasnt that stable and decided i wanted to change it back, I input custom serial number to change it back to normal.

After this the speedometer has been showing the wrong numbers, Maxes out at around 21kmh even in downhills where i know im going about 30kmh and external speedometers have shown me about 30kmh. Is there anyway to fix this? Its pretty annoying seeing the wrong speeds

I apologize in advance for the wording! Does the f30 not take well to region 40? Iv had this f30 and the front wheel and breaking sounds painful and motor seems to lock up?

Hey unfortunately I am also the owner of a ninebot f40D with updated soft to 5.7.7 Does anyone know when we can expect to be able to hack this to a global speed of 30 km/h instead of the current 20 km/h :/ . I know it is possible via st link but don't want to do it that way. So far this speed is quite a drama ;/ .

It could be soon, it could never happen. We don't know that.

Hi guys, I recently got hand on a Segway-Ninebot F20 (German version). I activated it using the SHU, and it turned out to have DRV 5.4.x installed. The SHU app is seemingly fully operable. However, the scooter will never reach higher speeds than 22km/h, no matter which operating mode is selected (like Global 30, EU 25,...). With the original SN, the scooter will go up to 20km/h only, with any adjusted SN, as stated, the maximum speed is somehow locked at 22. I could not find a way to go up to 25km/h at least.
All speeds tested freewheel. Any idea what could be the cause? Thanks in advance!
