Now I have the latest version 5.8.4, how can I downgrade to version 5.6.9 and below?

I can't change it back and I can't even change back the region code.
I can't change anything the scooter seems to be locked.?!

BLE 3.0.7
DRV 5.7.7
That's because you have one of the locked firmware versions installed.

I have an F30 and I live in Europe, when I change the region to Global F40 and accelerate the brakes make me stop, my DRV version is 5.4.9,BLE is 3.0.7.
If I need to downgrade something can anyone please tell me what I need to do?

Its been posted before many times that F30 scooter has weaker motor than f40 that's why your scooter struggle to accelerate. You have to add gas very gently, but i advise you to change region to F30 global.

I have done some tests today with F30. I changed region to F30 global and i could ride at 25km/h. Than i changed it to F40 and tried to push it to the limits, speedmeter shows only 20km, but i could feel its a bit faster so i instlled on my phone some gps tracking speed app to check the accual speed and max i could do was 25km/h (offcourse i had an acceleration issue as everyone else here).

Anyone knows is there a way to fix speed on the screen to show real numbers?

I’ve just did a region change on DRV 5.8.9 on Ninebot F40E via the SHU app and as far as I can tell it works! The serial number and the region changed in the app, the scooter only displays 25-26 kmph, but the GPS app on my phone says 30.5 kmph, and it also feels faster than before. No issues with acceleration or anything else so far.

Firmware 5.8.9. The change of region was successful, on the idling move shows 30 km/h. forgive English not native, translator.

I guess that it's not true as I am not aware of any updates regarding the any new hacking process for newer firmware versions.
Pictures or didn't happen.

BTW guys, do you have any guide regarding F series scooters and ST-Link hack? Haven't seen anyone doing it and wondering whether that would really work?
