Owners of the popular fitness trackers Xiaomi Mi Band 4 periodically face situations when the device begins to work incorrectly, interface glitches, refusal to pair with a smartphone or simply the desire to transfer the gadget to another person requires radical measures.
The process of restoring the original parameters does not require special technical skills or expensive equipment; the entire procedure takes only a few minutes and is carried out through a standard mobile application, but it is important to understand the difference between simply turning off the tracker and completely deleting all user data.
In this article, we will discuss in detail all available methods of returning a device to life. You will learn how to properly prepare a gadget for resale, eliminate software errors and avoid common problems when re-synchronizing.
Why you need a complete tracker reset
The main reason users are looking for a way to reset the Xiaomi Band 4 is a critical software error: Sometimes the tracker stops responding to touch, hangs on the logo or refuses to transmit pulse data, in which cases Hard Reset becomes the only way to resuscitate the device without going to the service center.
The second common scenario is a change of ownership: If you plan to sell your fitness bracelet or give it to a friend, it is crucial to delete all personal information. Reset allows you to clear your activity history, health data and link to your Mi Account, which ensures the confidentiality of your data after transferring the device to other hands.
⚠️ Warning: Once the reset procedure is complete, all accumulated training statistics will be permanently deleted from the device itself. Make sure that the data is synced to the cloud if it is important to you.
Reset may also be required when trying to connect the bracelet to a new smartphone if the previous pairing was incorrect. Sometimes the system "remembers" connection errors, and a clean installation helps to establish stable contact over Bluetooth.
Preparation for the resetting procedure
Before you start active actions, you need to follow a number of preparatory steps, ignoring these recommendations can cause the device to shut down at the most inopportune moment, which can damage the software part, first of all make sure that the battery charge of the tracker is at least 20-30%.
The reset process, though fast, still requires energy to overwrite system files, and if the battery runs out during the formatting of internal memory, the bracelet can turn into a “brick”, the recovery of which will require soldering of memory chips.
You’ll also need a smartphone with the Zepp Life app installed (formerly known as Mi Fit) that controls most of the tracker’s features through the software interface. Make sure the phone has Bluetooth enabled and a stable internet connection, as the app may need to check the status of the device on the server.
💡
Before reset, take screenshots of the important settings or dials you used to quickly restore the familiar look of the interface after the procedure.
Reset via Zepp Life (Mi Fit)
This is the safest and most recommended method by the manufacturer, and it ensures that all data is deleted correctly and the device itself will log out of your account. First, open the app on your smartphone and go to the Profile tab.
In my list of devices, find your Xiaomi Mi Band 4. Click on the tracker name to enter the control menu. Here you need to find the "Unbind" or "Unbind" button. Depending on the version of the application and the interface language, the name may vary slightly, but the meaning remains the same.
When you press the button, the system will request confirmation of the action, the app will warn you that all data will be deleted, agreeing, you initiate a command that will go to the bracelet, on the monitor screen the notification will appear about the disconnection, after which it will return to the state in which it was immediately after being removed from the box.
☑️ Checklist for preparation for discharge
Alternative methods of recovery
In some cases, the standard path through the app menu may not be available, such as if the bracelet is getting stuck and does not respond to commands, or if the app does not see the device, and in such situations, you can try a forced reboot, which often acts as a soft reset.
To do this, connect the tracker to the charger. At the time of connecting contacts, the system often automatically restarts. If this does not help, you can use the device search function in the application. Active connection and subsequent break sometimes shake up the software of the gadget.
There's also a deep discharge method, but it's not recommended as a regular one by experts. If you leave the device to zero for a long time, it can reset some of the time settings when you charge it later, but it's unpredictable and can have a negative impact on the life of a lithium polymer battery.
⚠️ Warning: Do not attempt to disassemble the Xiaomi Band 4 body to retrieve the battery for reset.The capsule is sealed and the autopsy will cause irreversible damage to the moisture protection and the device itself.
Table: Comparison of discharge methods
To better understand the differences between recovery methods, we will look at their characteristics in a comparative table, which will help you choose the best option depending on your specific situation.
| Method | Security of data | Required SOFTWARE | Efficiency |
|---|---|---|---|
| Through the Zepp Life app | High (staff removal) | Required. | 100% |
| Forced reset | Medium (soft discharge) | Not required | 60-70% |
| Zero discharge | Low (risk to the battery) | Not required | Low. |
| Flashing (DFU) | High (full cleaning) | Specialty software. | 100% |
As you can see from the table, using the official application remains the most reliable way, other methods should be considered only as a temporary measure or if the regular functionality is completely unavailable.
What to do if the “untie” button is inactive?
Possible problems and solutions
Users may encounter a number of difficulties in resetting, and one of the most common problems is when the bracelet does not open the pair, in which case removing the device from the Bluetooth list in the settings of the smartphone operating system before trying again in the application helps.
Another common error is the message "I couldn't untie" and this can be due to an unstable Internet connection, because the server needs to confirm the operation, check the Wi-Fi or mobile Internet connection, and make sure that Xiaomi servers are not running scheduled maintenance.
If the tracker stopped turning on or displaying strange characters after reset, the deletion process may have been interrupted, in which case it is recommended to connect the device to charging for several hours. If the problem does not disappear, you will need to flash through specialized software, which is a more complex procedure.
💡
In most cases, the problem is solved by simply removing the device from the phone's Bluetooth settings and re-associating through the app.
Tracker setup after reset
After successfully completing the reset procedure, your Xiaomi Mi Band 4 will request pairing again.The welcome screen will prompt you to select a language and scan. QR-Follow the instructions on the display that are duplicated in the app.
It is important to reconfigure all notifications that have been reset. Go to the device profile in the app and select "Application Notifications." You can activate (push notifications) for instant messengers, calls and SMS. Without this setting, the bracelet will remain silent even if the phone receives messages.
Also, be sure to set your activity goals, time format (12 or 24 hours) and preferred dial. For many users, personalization of the interface is the key to returning to comfortable use of the gadget.
⚠️ Warning: After reset, re-enable the Wrist Raise to Turn on the Screen function if you need it. It can be activated by default, but the motion sensor calibration requires the first hand lift.
