Owners of popular fitness trackers from Xiaomi periodically face situations when the device ceases to respond correctly to commands or completely freezes. Resetting in such cases becomes the only effective solution to bring the gadget back to life without contacting the service center. Most often, the need for this procedure arises when updating the firmware, changing the owner or critical synchronization errors.
The process of returning to factory parameters on the Mi Band 4 does not require special technical knowledge or complex tools, but it is important to understand the difference between a software restart and a complete memory cleanup, as these actions lead to different results. In this article, we will discuss all the available methods in detail so that you can choose the most suitable for your situation.
When you need a complete reset of the tracker settings
The main reason for the radical cleanup measures is that the device is not working properly, which cannot be corrected by a normal restart. If your fitness bracelet has stopped transmitting data to your smartphone or shows the wrong time, this is the first signal that you need to intervene in the system.
Also, a reset is often required when transferring a device to another user, so that the new owner can seamlessly link the tracker to his account, you need to completely untie it from the previous phone. Without resetting, the new device will not be able to detect the bracelet to pair, since it will remain in the memory of the old phone and block new connections.
There are several clear signs that it is time to clear the data:
- 📉 Tracker stopped counting steps and pulse, although the sensors are physically healthy.
- 🔗 Permanent Bluetooth connection breaks for no apparent reason.
- 🔄 The device stuck on the logo when it was turned on or updated.
- 📱 The “device is busy” error when trying to connect to a new phone.
Ignoring these symptoms can cause a software error to become irreversible and the device needs to be repaired.Timely cleaning up memory helps avoid more serious hardware problems in the future.
Preparation for the data-dumping procedure
Before you start active recovery, you need to perform a number of preparatory operations, first of all, make sure that the battery charge is at least 30-40%. If the battery runs out during cleaning or updating, this can lead to damage to the system files and complete failure of the tracker.
It is also important to understand that the reset will destroy all accumulated data about training and activity stored directly in the memory of the wristband, data that has already been synchronized with the cloud or the Mi Fit application (now Zepp Life), will remain safe, but local statistics will be irretrievably lost.
☑️ Pre-reset check
It is recommended to check in advance for updates to the application on your smartphone. Using the current version of the software minimizes the risk of communication errors between devices. If you have an old version of Mi Fit installed, it is better to update it first through the official app store.
Method 1: Reset through the menu of the bracelet
The easiest and safest way to return to factory settings is through the wearable interface, which is suitable for touch-sensitive displays and menus that are available for navigation, and you don't need any additional gadgets or a computer.
To perform the operation, follow the next path in the tracker menu. Find More, then select Settings, and at the bottom of the list, find Unbind or Factory Reset, if available in your version of the firmware. Confirm the action by touch.
⚠️ Warning: Once the detachment point is selected, the bracelet will automatically break the connection to the smartphone and clear all user data.
If the menu does not have a direct Reset option, use the Untie feature, which forcefully initiates the cleanup of the configuration files on the tracker side, which is equivalent to a complete reset. The device screen will go out, and in a few seconds the Xiaomi logo will appear, indicating the reboot.
💡
Using the built-in menu is the safest method, as it is controlled by the software of the device itself and minimizes the risks of firmware damage.
Method 2: Uncoupling with Mi Fit or Zepp Life
If the touch control on the wristband is difficult or the screen does not respond, you can initiate the reset remotely via the application on the smartphone. This method is standard and preferable for most users, as it ensures that all background synchronization processes are correctly completed before cleaning.
Open the Zepp Life app (formerly Mi Fit) on your smartphone and go to your device profile. From the list of connected gadgets, select your Mi Band 4. You need to find the Unbind button, which is usually located at the bottom of the screen or in the device settings menu (three dots or gear).
The remote discharge process is as follows:
- 📲 Click on the icon of your bracelet in the app.
- ⚙️ Select "Settings" or "Device Management».
- 🗑️ Click the “Untie” button and confirm the action in the pop-up window.
- ⏳ Wait for the vibration of the bracelet and the appearance of the download logo.
Once these steps are successfully completed, the tracker will return to the out-of-the-box state: all personalization settings, such as dials and step goals, will be reset to default values.
Method 3: Forced resetting when getting stuck
In situations where the bracelet has completely stopped responding to touch and does not connect to the phone, the use of forced reboot methods is required, this is an extreme measure that helps to get out of the dead loop or deep freeze of the system.
The first and easiest way is to charge the device, and connecting to the power source on the Mi Band 4 automatically triggers a system reboot even if the screen is out, and if that method doesn't work, you can try to drain the battery before it's completely turned off and then recharge the device again.
| Method | Efficiency | Risk of data loss | Difficulty |
|---|---|---|---|
| Through the wristband menu | Tall. | Complete. | Low. |
| Through the app | Tall. | Complete. | Low. |
| Complete discharge. | Medium | High-pitched | Low. |
| Flip-flashing | Maximum | Complete. | Tall. |
There is also a method of “hard” reboot by holding the touch area, but on the Mi Band 4 model it is not implemented as clearly as on smartphones. Most often, the system simply ignores long presses for critical kernel errors, in which case it is only necessary to wait for discharge or use special utilities for flashing.
Secret combination for reboot
Firmware as a way of deep recovery
If standard reset methods don't work, you can use the flashing procedure, which is a more complex technical process that allows you to replace damaged system files with fresh ones, and this will require a third-party application, such as Notify for Mi Band or an official utility for updating.
You need to download the current firmware file for your model and start the update process through the application. When you install new software, the device automatically cleans the old data, and flashing it is the most radical, but also the most effective way to treat software errors.
⚠️ Warning: Interrupting the firmware process (battery discharge or loss of communication) can turn the bracelet into a “brick” that cannot be restored at home.
Make sure your phone is near the bracelet and your smartphone screen doesn’t go out during the process. Follow the instructions on the app screen and don’t try to use the tracker until you have completed the new version of the software. Once you have successfully upgraded, you’ll get a fully clean and working device.
💡
Keep important training data in the cloud before any reset, as the local history on the bracelet is always deleted without the possibility of recovery.
