The procedure for untieing the wearable Xiaomi Mi Band 4 gadget can be required in various situations, for example, when selling the device, transferring to another user or when critical synchronization errors occur. Bracelet untie is not just a Bluetooth disconnection, but a complete break in the digital connection between the tracker and the account in the manufacturer's cloud. If you plan to sell your Mi Band 4, it is extremely important to complete all the steps correctly so that the new owner can seamlessly link the device to his smartphone.
Many users mistakenly believe that it is enough to remove the Mi Fit or Zepp Life app to make the gadget free. This is not true. Data about the serial number and binding remain on the company's servers, blocking the possibility of re-registration. In this article, we will discuss in detail the algorithm of actions that will completely clear the history of the device and prepare it for new use or reconnection.
Note that the process may differ depending on whether the original application or third-party counterparts are used. The reset procedure affects both the software part of the phone and the hardware memory of the tracker itself. Incorrectly following the steps can lead to the device remaining locked in the old account, making it useless for other people without your intervention.
Preparation for uncoupling of the device
Before you start manipulating, you need to make sure that your Xiaomi Mi Band 4 is charged at least 20-30%. The detachment process and subsequent reset may require active data transfer, and a sudden power outage will interrupt the procedure. Also check that your smartphone is on Bluetooth and has stable Internet access, as the command to uncoup is sent to the server.
It is recommended to update the Zepp Life app (formerly Mi Fit) to the latest version in advance. In older versions of the interface, some menu items may be located differently or not work correctly. If you use iOS, make sure that the application has all the necessary permissions to work in the background and access to geolocation.
⚠️ Warning: Before unloading, be sure to complete data synchronization to save your activity, sleep and pulse history in the application archive.
It's important to understand the difference between simply turning off Bluetooth settings and fully uncoupling. The first action only breaks the current connection, but leaves the device tied to the account. To completely clean up, you need to use the functionality of the application itself. Deleting from the list of devices inside the application is the first and foremost step that initiates the cleanup process.
Uncoupling through the Zepp Life app
The main method of controlling the tracker is through the official app. The interface may vary depending on the version, but the logic remains the same. Open the Zepp Life app on your smartphone and go to the Profile tab in the lower right corner. Here you can see a list of all the connected devices.
Find your Mi Band 4 and click on it. The device management page will open with the basic settings. Scroll down until you find the Unbind or Unununtie button. Click on it and confirm your actions in the pop-up window.
- 📱 Open the application and go to the user profile.
- ⌚ Select your bracelet from the list of available devices.
- ❌ Click the "Untie" button at the bottom of the screen.
- ✅ Confirm the operation in the dialog window.
Once confirmed, the communication will be broken, the operation status will appear on the smartphone screen, at which point the application will send a request to the server to unblock the unique identifier of your bracelet, and if the Internet connection is stable, the process takes a few seconds.
☑️ Pre-uncoupling check
It is important to wait for the message of successful completion. If the process is interrupted, the device may remain in a state of waiting for connection, but formally still listed behind your account, in which case it is recommended to repeat the procedure, pre-rebooting the smartphone.
Resetting settings to factory
Once the app has been successfully unbundled, you need to reset the settings on the device itself, especially if you're planning to sell it, ensuring that the tracker doesn't have any personal data left on it, such as alarm settings, step targets or personalized dials.
There is no physical button to reset the Mi Band 4, so all actions are done via the touch screen of the bracelet. Swipe left or right on the tracker screen until you find the Additional menu (three-dot icon or gear).
⚠️ Warning: After the reset, all the data accumulated for the current day that has not yet been synchronized with the smartphone will be lost.
Click on the reset point and hold your finger on the screen or confirm the action if required. The bracelet vibrates and resets, after which the Mi logo appears on the screen and a request to scan. QR-This means that the device is fully cleaned and ready to work with the new owner.
What to do if the reset does not work?
In some cases, if the bracelet was tied to the account but the application is removed, resetting through the bracelet menu is the only way to free the device.However, without prior detachment in the application, the new user will still not be able to register it, since the server will give an error "Device is occupied".
Delete from your Mi Cloud account
Even after the app is unplugged and reset, the device can remain in the list of your gadgets in the Mi Cloud storage. To completely clean the digital footprint, it is recommended to check the web interface or account settings. This is especially true if you change your region of residence or main account.
Go to the official Xiaomi service website and log in under your login. Go to the Device Management section. Here you will see a list of all the equipment ever tied to your ID. Find your Mi Band 4 and select the uninstall or unbundle option.
This move is important for those selling the device so that the buyer does not have questions about the origin of the gadget and its purity in terms of privacy.Removal from the cloud ensures that no configuration backups will automatically pull up when trying to re-bind.
| Action. | Where it's done | The result |
|---|---|---|
| Annex decoupling | Zepp Life / Mi Fit | Breaking the connection with the server |
| Resetting settings | Menu bracelets | Deletion of data from the device |
| Deletion from the account | Mi Website / Phone Settings | Cleaning the list of trusted devices |
| Bluetooth shutdown | Settings of the smartphone OS | Temporary suspension of communications |
Don't ignore this stage if you care about the security of your data. Although fitness trackers don't store passwords from banking apps, your travel history and activity can tell you more about your lifestyle than you'd like.
Solving the unbundling problems
Sometimes it doesn't go according to plan. The bracelet may not respond to commands, or the app will give you a network error. In such cases, you shouldn't panic. Most often, the problem is an unstable connection or the app's cache. Try clearing the Zepp Life app cache in your Android or iOS settings.
If the bracelet doesn't untie, try the following algorithm: completely uninstall the app, restart the phone, install the app again, log in and repeat the procedure. Sometimes it helps to turn off your phone's Wi-Fi and use mobile Internet (or vice versa) to eliminate problems with the provider.
- 🔄 Reboot your smartphone and bracelet.
- 📶 Check the stability of the Internet connection.
- 🗑️ Clear the app cache or reinstall it.
- 🔋 Make sure the bracelet is charged.
In rare cases, Xiaomi servers may be doing maintenance work that temporarily blocks the possibility of changing the status of devices. If nothing helps, wait a few hours and try again. Technical failures on the manufacturer's side are rare, but they can not be completely ruled out.
💡
If the bracelet has stopped responding to touch after a failed detachment attempt, put it on the charger for 10-15 minutes. This often resuscitates the touch layer.
Frequent User Errors
One of the most common mistakes is to untie the device through the Bluetooth settings in the phone, where users choose "Forget the device" in the system menu, thinking that this is enough, but the binding is at the account level, not just the radio module.
Another mistake is ignoring messages of synchronization errors before selling, and if you sell a data-stuck bracelet, the new owner will have trouble trying to sync the first time, as the app will try to fill in the old cache. Always bring the synchronization process to the end before resetting.
⚠️ Warning: Don't try to disassemble the contact reset bracelet.The Mi Band 4 doesn't have a hardware reset button, and opening the case will break the moisture protection and cause you to lose warranty.
Also, users often forget that after the detachment, you need to reset alarm clocks and targets. When transferring the device to another person, be sure to mention this so that the person does not think that the gadget is defective due to the lack of vibration in the morning.
💡
Complete decoupling requires action in three places: an app, a wristband menu, and a cloud account, and skipping any stage can lead to problems when reused.
