This tutorial is similar to the one for the Ninebot ESX Series.
Often the max speed is set through a serial number prefix.
In order to change your vehicle’s region and unlock its max speed, change the 4th digit of your serial number.
Below is a list of serial prefixes and their effect on max speed and vehicle app appearance, courtesy of myself and FoxMaster at ScooterHacking.
Choose the one corresponding to the region you want.
On Windows, there are two main apps that can easily be used to change the Serial prefix.
Ninebot IAP and Ninebot Flasher are based on similar code-bases but have different GUI’s.
Ninebot IAP makes it a little easier to change a serial due to its one-click buttons for changing SN.
Both applications require your computer to have BLE support unless you are using serial for IAP.
Ninebot IAP is an app developed by Scooterhacking.org.
Once you have it installed, open it and press the “Start scan” button.
Select your device in the menu and press “Connect”.
It may ask you to press the power button to pair, in this case, short press the button that you would normally use to power it on or toggle the headlight.
If it shows version numbers in the “Installed Firmware” box, you have successfully connected.
From here head to the “Tools” menu under “Utilities”.
Press “Read” in the “ESC Serial Number” panel.
Next, press “Change SN” and type your serial number out exactly as it was before, but change the 4th digit to the prefix you chose above.
In my case, that would be changing the D after N4G to a C if I wanted the speed to be limited to 25 kmh.
Press “OK”, then you should hear your scooter beep twice in quick succession.
To confirm it has successfully changed, press “Read” again and you should see your new serial.
Test the new speed or appearance in the app and it should be good to go.
Ninebot-Flasher is available from the Microsoft store.
Once installed, press “Start Scan” and select the device you want to flash by clicking “Connect”.
It will likely prompt you to “Press the power button to pair”.
Short press the button that you would normally use to power it on or toggle the headlight.
You will know the connection is successful if the greyed out buttons become white and your Serial Number is printed in the console.
Copy that number down somewhere.
Click on the text box to the left of “SendCmd” and then press Ctrl + alt + a on your keyboard.
You should now have more options as shown below.
Paste your old serial in the box but change the 4th digit to the serial prefix you selected above.
Here I have the fastest prefix S and am changing it to a 25kmh prefix C but you may be interested in speed limiting your scooter whether for a child or to avoid legal issues.
Press “Write ESC Sn” twice and your new region should be set.
ScooterHacking Utility (SHU/SHUtility) is available from the Google Play Store and here is how to use it to change your region.
Once installed, the app will prompt you for location permissions.
This is to allow it to access your Bluetooth.
Once you press ok, android will ask if you want to give SHU location access, press allow.
After giving it Bluetooth access, the app will give you a warning message that lets you know the risks of flashing custom firmware.
Read it and press agree.
Now that you’re past the warnings and TOC’s, you can scan for the scooter you want to change the region on and select it from the list.
After a successful connection, note the current serial number, and write it down in case something happens in the future or you lose it.
A successful connection will show the firmware version numbers and serial number.
After saving your old serial number, proceed to the lower part of the main screen to get to the “Tools” section and click “Change Region”.
From here, a list of region options will pop up. Choose the region you wish to change to (Choose US for the fastest speed).
Once you click an option, you will hear the scooter beep a few times and then the serial will have been changed and the region will be set.
*Depreciated, recommended to use ScooterHacking Utility as mentioned above
XiaoFlasher is available from the Google Play Store and here is how to use it to change your region.
Once installed, give it permission to access files and “Location”.
XiaoFlasher just needs location access in order to use Bluetooth which we need for this tutorial.
On the next screen, agree to the TOS and close the changelog.
Click on the name of your device to connect.
If XiaoFlasher has successfully connected you will see firmware version numbers on the upper right-hand side.
Once successfully connected, press “Change Region”.
In this menu select the region you would like.
The developer has made a 30s wait time and an ad that you must watch in order to change the region.
Once you have sat through that and likely decided to use another app in the future, you will hear the scooter beep twice indicating a successful region change.
There is currently only one application for iPhone/iOS to change the region of a Ninebot Max/G30 and it’s still in beta as if the time this post was written.
You will need Testflight to install it, but this link should install it if you don’t.
Download Scooter Companion https://testflight.apple.com/join/RaFiBTgi.
Open the app and scan for your device.
Click on the scooter that you want to perform the region change on.
Once it connects and displays information about the scooter, click on “Utilities” on the top menu.
From here, scroll down to “Adjust scooter region” and click the region you want (US would be fastest, followed by EU, then DE).
