How to untie the Xiaomi scooter from the application: the complete guide

EV owners often face the need to change their account, sell their device or switch to another smartphone. In the Xiaomi and Ninebot ecosystem, the process of untieing the scooter is not always obvious, since it is tied to the server part and is linked to a specific UID device. If you simply delete the application or change your phone, the scooter may remain locked for the new owner or not connect to a new account.

There are several ways to solve this problem, from standard removal through the menu to the use of engineering reset methods. The choice of the specific method depends on the model of your vehicle, the version of the firmware and the region to which the electric scooter was originally attached. In this article, we will discuss all options in detail, including the complex cases with the Chinese versions of devices.

Care should be taken to ensure safety before any manipulations are initiated. Incorrectly resetting the binding on some models can result in a complete locking of the controller, requiring service intervention. So follow the steps described below strictly and do not interrupt the flashing or reset process halfway.

Why you need to disconnect the scooter from the account

The main reason why you need to unplug is to sell the device, so as long as the scooter is on your Mi Home or Ninebot profile, the new owner won't be able to activate it on his phone, and the security system sees that the serial number is already registered, and blocks re-activation, which is designed to protect against theft, but it's uncomfortable with legal transfer of ownership.

Another common scenario is a change of region or account, where many users buy Chinese versions of scooters that require a change of region in the app to China, and if you decide to reflash the device to the global version or simply change the main Mi Account, the old binding will conflict with the new settings, in which case the server binding becomes an obstacle to normal operation.

There are also situations where an account has been hacked or access to the phone on which the initial activation was made is lost, in which case the standard methods may not work, and you will need to have a deeper intervention in the settings of the Bluetooth module and the memory of the controller. It is important to understand that the undocking is not just removing the device from the list, it is a command on the server about the change of ownership.

⚠️ Warning: If you buy a used scooter, always require the seller to demonstrate the detachment process in your presence.

Preparation for the unbundling: what to do before the beginning

Before you start manipulating the software, you need to make sure that the device is ready for the procedure. First of all, check the battery level. The process of detachment and possible flashing requires stable power, and if the battery runs out at a critical moment, the controller can fail. Charge the scooter to a minimum of 60-70%.

The second important step is to update the app to the latest version. Older versions of Mi Home or Ninebot may contain bugs that prevent you from correctly sending a command to the server about removing the device. Go to the app store and make sure you have an up-to-date build installed. It is also recommended to update the firmware of the scooter itself to the latest available version through the settings menu.

Remember to back up important data if it is stored in the device’s memory (such as travel history or custom brightness and recovery settings). Although personal data is not usually erased when uncoupled, resetting the Bluetooth module settings can result in paired connections being lost.

☑️ Pre-uncoupling check

Done: 0 / 5

Make sure you remember the password from your Mi Account or Ninebot account. During the unbundling process, the system may request a re-authorization to verify the identity of the owner. If you forget the password, the process may be delayed indefinitely due to access restoration procedures.

The standard method of detachment through the Mi Home application

The easiest and safest way to unplug a device is to use the official menu in the app, which is suitable for most cases when you have access to an account to which the scooter is attached. Open the Mi Home app and go to the home page where all connected devices are displayed.

Find your scooter card in the list. It's usually a model name, like "Mi Electric Scooter." Click on it to enter the control interface. In the upper right corner of the screen, you'll see a three-dot icon or a gear, which is the device settings menu. Click on it.

In the menu that opens, scroll down to the bottom of the list, and it should have a button called Delete Device or Unbind, and when you click it, it will request confirmation of action, it's accidental deletion protection, and you confirm the operation, and the application will send a request to the Xiaomi Cloud server.

⚠️ Note: If the Remove button is inactive or not, it means that the device may be actively restricted or in rental/enterprise management mode.

Once the command is successfully executed, the scooter will emit an audible signal and its indicators may blink. In the application, the device will disappear from the list. Now you can try connecting it to a new account. If the scooter does not respond to the search for a new phone, you may need to reboot.

The Ninebot (Segway-Ninebot) application

Many of Xiaomi's scooters (especially the Pro, Essential and Max series) are actually manufactured by Segway-Ninebot and controlled through their proprietary app. The logic of the junction is similar here, but the interface is different. Launch the Ninebot app and log in to your profile.

Select your scooter from the list of devices. In the main control menu, find the settings icon (usually the gear in the corner). In the settings menu, look for "Scooter settings" or "About the device." There should be an option "Unbind Scooter".

The system will alert you that once the trip history is unplugged, the device will be available to pair with another phone. Confirm. Unlike the Mi Home, this can take a little longer to process because of the security certificates.

What to do if the scooter does not go into pairing mode?
If the scooter is not detected by the new phone after detachment, try resetting the Bluetooth module. For this, on some models, you need to press the power button and the brake button simultaneously on the device. 10-15 It's going to force the communications module to restart."> Importantly, the Ninebot app is more strict about regional restrictions, and if you try to untie the Chinese version of the scooter using a European account, the process can end up in error. In such cases, it is recommended to use an app with a region corresponding to the version of the device. Problems with regions and Chinese versions One of the most common causes of problems with uncoupling is a mismatch between the region of the device and the account (CN version) is tightly bound to servers in China. If you've tried to activate a scooter through crutches or change region, it can be difficult to untie. Often, you'll find a scooter that shows up in the app, but the untie button doesn't work or you'll see a network error. This is because the command goes to the wrong server. In this case, you need to change the Mi Home app settings to China, even if your account is registered to another country. After changing the region, the application may require you to log in again. Now, try to find the device (sometimes you need to add it manually by serial number, if it is missing from the list) and Xiaomi will run the server from this. Type version Region in the application Application Features of detachment Global (Global) Russia / Europe Mi Home / Ninebot Staff unchallenged Chinese (CN) China Mi Home (CN) Replacement of the region is required, European blocking is possible (EU) Germany/Netherlands Ninebot Strictly Checked VIN-Russian code (EAC) Mi Home / Ninebot is similar to the global servers in the EU ⚠️ Attention: If you change region in the Mi Home app, the list of devices can be cleared visually. Don't worry, after you return the region back, they may appear again, but to deflect the Chinese version, it is critical to be in the Chinese server segment. "Device is busy" and others Sometimes when you try to untie the user is confronted with a message "Device is busy" or "Can't contact the server." This may mean that the scooter is currently trying to sync data or update. Wait until all background processes are complete. If the error persists, try the following algorithm: 📱 Close the application completely (unload from memory). 📶 Switch your phone from Wi-Fi to mobile internet (or vice versa). 🔄 Reboot the scooter itself (turn off and turn on the power button). 🔓 Log in and log in again. In rare cases, cleaning the app cache helps. Go to your phone's settings, find Mi Home or Ninebot in the app list, and select Clear Cache. Don't confuse Clear Data with Clear Data, or you'll have to re-enter your account login and password. It's also worth checking if the app is running on another phone. If you're already logged in on a tablet or an old smartphone and there's scooter control open, the server can block commands from the new device for security reasons. Alternative methods and Bluetooth reset If standard methods don't work, you can try the "forced" search method. Some users report success when using the "Add Device" feature in the app when the scooter is already tethered. The app can detect a conflict and suggest that the device be untie from the old account. There is also a method of resetting through a combination of buttons, but it does not work on all models. 10-20 This results in the Bluetooth module being reset to factory settings, which sometimes breaks the software link to the account, although the server link may remain. UART-adapters, but this requires disassembly of the scooter deck and the presence of special equipment. This method is recommended only in extreme cases when the scooter needs to be reflashed to change the region (for example, with the help of a scooter). CN on Global), which automatically requires an unbundling. 💡The bottom line is that the standard uncoupling through the app menu is the only safe way to ensure that the owner is unlocked. Hardware can lead to a loss of warranty. What happens if you sell the scooter without junction? The new owner can't connect the scooter to his phone. The device will see a Wi-Fi or Bluetooth network, but when you try to control it will give an error "Device bound to another account." In fact, the scooter will turn into a brick for smart control, although it will still be possible to drive it (if the controller is not blocked). Can you untie the scooter without access to an account? Officially, no. It's a security mechanism against theft. The only way is to call Xiaomi or Ninebot for technical support, and they can provide a purchase check and a box with a serial number, and they can unlink it after they check the documents. Does the undocking affect the warranty? The application's detachment procedure itself does not affect the warranty. However, if you used third-party methods, changed the region programmatically or opened the plates to access the board, the warranty obligations can be waived. Do you need to reset the scooter to the factory settings after the detachment? This is recommended before selling to remove travel history and personal settings, usually via the About Device menu" -> "Reset" in the app before the final uncoupling. Why is the scooter not visible after the uncoupling? After the uncoupling, the scooter goes into standby mode. Make sure it's Bluetooth on (usually a blue light) and close to the phone, sometimes requiring a short press of the power button to activate the communication module.
