(TUT) Unlocking the Ninebot E-series (E22, E25, E45) to 28 km/h (30 on E45)

[Changer_E22E]

Goodmorning,
i have my E22E bricked with code E45D. I want to flash the fulldump file with my ST-link V2
I have edited the HEX of esc255_fulldump.bin at address 9020 withmy original code.
Now what i have to do?
I open the edited fulldump file with STM32 ST-LINK Utility and burn the firmware?
Please Help me, there is not a step by step guide for E22E
Thank you

Hi there,

I know it's been a long time since post creation, though I want to know is this still working?
And then, can I return ESC Sn to N2GG and will it work as before? Aand will it be possible to find out that I've been doing that?

Thank you, :>

Hello,

Big Thanks for all who is involved in this information thread! :) Maybe someone can help me with E45D ninebot flashing ?

Early i received SEGWAY NINEBOT E45D with external battery, but this device max speed is only 20 Km/h :( when going up to hill scooter goes slowly (even when sport mode is enabled :(

I don't really want super speeds, just 25 km/h would be little faster and little enough for me :)

unpacking new scooter i installed ninebot app and accidentally :) automatically :) :) clicked on firmware update so my scooter now have this data:
Drv 2.7.5, master control 2.6.15, ble 2.1.3, bms 1.6.0, battery 2: 1.6.0.
I tried flashing (load original 2.7.1) from scooterhacking utility, also tried another windows 10 and android apps: ninebot flasher, iap, xiaflasher - no results ! SN can't be changed and flashing all official firmwares i get error: update failed! reason: data format error

Question 1:
Also i see that in manual (viewtopic.php?f=6&t=346) there is requirements for bluetooth and bluetooth version must be 5.0 and higher ! But i have android phone with BT version 4.0 and windows 10 bluetooth adapter also with 4.0 version! - Maybe due to my bluetooth version i can't normally flasing device ? It is variant that today i pickup form store new BT adapter with higher version and give a try ! :)

Question 2:
Maybe there is an option to restore factory settings with factory firmware ?

Big Thanks !

Hello. After flashing e22 using stlink v2 with esc255_fulldump.bin - the dashboard does not work, when the button is turned on - nothing is displayed on the screen, the taillight of the scooter flashes several times. What could go wrong?

Region changing should work just fine on these firmware versions, though I'd recommend updating to DRV2.5.5 using ScooterHacking Utility since 2.5.0 is quite broken.

Hi TehnoCraft2010,

I have the same issue.

Thanks!

Is anybody working on a firmware for the ninebot air t15? Or anybody knows if the firmware Is the same as the e serietà?

wanna now it too, do you got the solution already?

So after changing to N2GQ S/N with my E25A with external battery. I reach 28km/H freewheeling and still stuck on 25km/H on the ground, about 26km/H in a slight decline.

I can't really to seem out why, any pointers?

[kitqeb]

Yup same here. Stuck at 26kmh on ground using 'Q' for my e22d. I mean it's better than the 20kmh I had before but it really sounds like the motor is capable of more power.
Does anyone know if there's a custom firmware coming soon?
And also, would it work to just change the board to a ES one? With ES dash and E motor?
