Modern wearables from Xiaomi, in particular the fourth model of the Mi Band, have proven to be reliable activity trackers, but even the most stable electronics sometimes require a reboot. Users often face situations when the device stops syncing, freezes on the screensaver or displays incorrect pulse data. In such cases, a standard shutdown does not help, and the only right solution is a complete reset to a factory state.
The process of returning to the original parameters can be done in several ways: software through the mobile application or hardware through the menu of the tracker itself. It is important to understand that after doing this, all accumulated training statistics, sleep history and personal settings will be deleted from the device.
Before we take any drastic measures, we need to make sure that the problem does require interference with system files. Often a simple re-entry or firmware update is enough. But if the gadget behaves unpredictable, ignores the commands of the smartphone or constantly loses connection, then hardware reset is the most effective method of eliminating software errors.
Reasons for performing a complete reset of the device
There are a number of specific symptoms that indicate the need to clean the memory and settings of the tracker, which is often used when selling a device to a new owner to delete their personal data, but there are technical reasons that can lead to complete inoperability of the gadget.
One of the common reasons is the desynchronization of data between the wristband and the smartphone. When notifications arrive late or not at all, it is often solved by cleaning the configuration. Also worth paying attention to the operation of the sensors: if the pulsemeter shows absurd values or the screen goes out prematurely, this is a signal of a software failure.
Here are the main situations that require intervention:
- 🔴 The bracelet constantly loses connection to the phone over Bluetooth.
- 🔴 The device hangs on the logo when switched on or while working.
- 🔴 Inability to install firmware updates through the application.
- 🔴 Transferring the tracker to another user or returning to the store.
⚠️ Warning: Before performing the reset, make sure that the battery charge is at least 20-30%. If the device turns off during the process of writing system files, this can lead to irreversible damage to the software.
Sometimes the problem isn't with the bracelet itself, but with the app's cache on the phone. Before you reset the settings on the gadget, try clearing the Mi Fit app's data on your smartphone. If that doesn't work, move on to the following methods.
Preparation for the resetting procedure
Quality training minimizes the risk of losing important data and ensures that the process is successfully completed. First of all, check the sync status. Open the application on your smartphone and force the data to be updated by pulling the screen down. This ensures that all your steps, calories and achievements are stored in the cloud.
The second important step is to check the firmware version, and sometimes the bugs you're trying to fix with a reset have already been fixed by the developers in a new update, go to the device profile and see if there's any updates, and if the new version is available, you better update first, and then, if the problem persists, reset.
☑️ Xiaomi Mi Band 4 Preparation for Reset
It is also worth turning off alarm clocks and sedentary reminders in advance if you plan to use a complex reset method that requires interaction with the menu. Although they will still be removed if completely reset, pre-preparedness will help avoid unnecessary vibration and sound signals in the process.
If you plan to sell a device, remember to untie it from your in-app account. Just resetting the bracelet itself is not enough – it can remain “tied” to your cloud profile, which will make it difficult for the new owner to pair.
Method 1: Reset via Mi Fit or Zepp Life
The most secure and recommended way to return the Xiaomi Mi Band 4 to factory settings is to use the official mobile application, which allows you to programmatically initiate memory cleanup without the risk of damaging system files with improper actions with the button.
To start, open the app on your smartphone and go to the Profile tab. Find your bracelet in the device list. If the device is displayed as "unplugged," pair it first. After you log into the gadget control menu, scroll to the bottom.
You'll find Settings or Control where the Unbind button is located. Pressing this button initiates the disconnection process. The app will alert you that all data will be deleted from the device. Confirm the action and the bracelet will automatically reboot in factory condition.
What happens when you untie?
Once the procedure is complete, the bracelet screen will go out and light up again with the welcome MI logo, which means that the reset was successful. Now you can re-search the device in the app and configure it as new.
It is important to note that this method does not always help if the bracelet is in a deep freeze and does not respond to the commands of the smartphone, in such cases, you need to move to hardware methods or the use of third-party software.
Method 2: Hardware reset via bracelet menu
If the app is unavailable or the bracelet is not connected to the phone, you can try resetting through the device’s built-in menu, which only works if the touch screen responds to touch and the interface is not completely locked.
On the home screen, swipe left or right until you find the Settings (cog icon) item, enter it and scroll through the options list to the end, and it should be Bind or Reset, depending on the firmware version and region.
Select the de-encourse and hold your finger on the confirmation icon (usually a checkmark or smartphone icon) for 3-5 seconds. The device vibrates and reboots. If there is no direct Reset option on the menu, try to find the About option and repeatedly click on the firmware version - this sometimes opens a hidden engineering menu, but on Mi Band 4 this trick rarely works.
| Resetting method | Conditions required | Risk of data loss | Difficulty |
|---|---|---|---|
| Through the app | Working Bluetooth, charged phone | Low (data in the cloud) | Low. |
| Through the wristband menu | Working touchscreen, access to the menu | Medium. | Medium |
| Through Notify for Mi Band | Third-party software installed | Low. | Medium |
| Battery discharge | Time (2-4 days) | High (for battery) | Low. |
Consider that the interface of the fourth model is quite minimal, and finding the right option can be difficult. If you do not see the reset point, your firmware version may not support this function directly through the menu, and you will have to use other methods.
Use of third-party applications for resetting
Official methods don’t always work, especially when working with bug devices, and third-party utilities developed by enthusiasts come to the rescue, and the most popular and reliable tool for Android is the Notify for Mi Band app.
This app can interact with the bracelet at a deeper level than the standard Mi Fit. After installing and pairing through it, go to Devices and select your tracker. From the control menu, find Factory Reset or Reset.
💡
The Notify for Mi Band app allows you not only to reset the settings, but also to reassign the button functions, set your dials and change the vibration logic, which is not available in standard software.
The advantage of this method is that it can often reach the bracelet even when the official app says "device is not responding." However, use third-party software with caution: only provide the necessary permissions.
After completing the reset command via a third-party app, be sure to remove the device from the Bluetooth list in the phone settings to avoid conflicts when reconnecting.
If this method has not worked, and the bracelet continues to hang on the logo or not respond, the last, most radical, but sometimes the only possible option remains.
What to do if the bracelet is frozen and does not respond
A situation where Xiaomi Mi Band 4 is completely locked, the screen is black or the logo is on, and there is no reaction to the touch, is called a soft breech. In this case, the software methods are powerless, because the operating system does not follow the commands.
The only way out is to completely drain the battery. Leave the bracelet alone for 2-4 days. When the charge drops to a critical minimum, the device will turn off. Then put it on charge and turn it on. Often after this deep sleep cycle, the system starts in normal mode.
⚠️ Attention: Full discharge is harmful to lithium polymer batteries. Do not use it regularly, only in emergency cases when other methods do not work.
There's a myth that if you put the bracelet on charge and press the touch button 10 times quickly, you'll reset. In practice, this doesn't work for the Mi Band 4 and can only make things worse by causing chaotic reboots. You'd better trust the discharge method.
If the problem persists after full discharge and charging, there is a high probability of a physical malfunction: the display plume has gone away or the power controller has failed, in which case only a service center or a replacement device will help.
