Modern wearables like the Xiaomi Mi Band 4 have become an integral part of millions of users’ lives, tracking activity and notifications. However, like any complex electronics, the tracker can encounter software failures, synchronization errors, or simply require transfer to a new owner. In such situations, the only sure solution is a complete reset to factory settings, which cleans the device’s internal memory of accumulated debris and returns the original state of the software.
Many users are afraid to do this, thinking it’s difficult or risky for the device itself. In fact, the process of returning the Mi Smart Band 4 to its original state is fairly simple and safe if you follow a certain algorithm of actions. It’s important to understand the difference between a normal reboot and a full formatting to choose the right method of solving your problem.
In this article, we will discuss in detail all the available ways to reset the Xiaomi Band 4 bracelet using both official applications and third-party utilities. You will learn how to prepare for the procedure so as not to lose important training data, and what to do if the device stopped responding to commands.
Preparation for the resetting procedure
Before you start drastic measures to clean the tracker memory, you need to perform a number of preparatory steps, which ensures that you do not lose the accumulated statistics over the long months of wearing the device. First of all, open the Mi Fit app (or Zepp Life) on your smartphone and make sure that the bracelet is connected and synchronized.
Pay attention to the battery level. If the battery is down below 20%, the reset process can be interrupted, leading to unpredictable errors in the firmware, put the tracker on charge and wait until the indicator shows sufficient energy level.
⚠️ Warning: Full reset irreversibly deletes all data stored directly in the bracelet memory, including unsaved workouts and dial settings. Make sure activity history is successfully uploaded to the cloud.
It’s also worth checking if the device is tied to a Mi Cloud account with search activated, although this is less relevant for Band 4 than for smartphones.
☑️ Checklist before reset
Reset via the official Mi Fit app
The safest and most recommended way to return Xiaomi Band 4 to factory parameters is to use the standard software. This method ensures that all system processes are completed correctly and internal memory is formatted correctly. First, open the Mi Fit app on your smartphone and go to the Profile tab.
From the list of connected devices, select your Mi Band 4. You need to find the "Unlock" or "Unbind" option, which is usually located at the bottom of the device menu. Pressing this button initiates the process of disconnecting the connection and cleaning the data. The system will warn you that all data will be deleted.
After confirmation of action, the bracelet vibrates and reboots, greeting you with a greeting screen with a sleek look. QR-So this means that the factory reset was successful, and the device is ready for re-binding or for sale.
💡
Using the official “Untie” button in the application is the only guaranteed way to cleanly delete data without risking damage to the firmware.
Sometimes the process can be delayed if the Bluetooth connection is unstable, in which case keep the smartphone as close to the tracker as possible and do not open other heavy applications that can intercept the resource of the wireless module.
Use the Notify for Mi Band app
If the official Mi Fit app doesn’t see the device or the detachment function doesn’t work, third-party utilities come to the rescue.One of the most powerful tools for Xiaomi tracker owners is the Notify for Mi Band app. It provides advanced management capabilities, including deep resetting.
After you have installed and paired the tracker with the Notify app, go to the tool section. Here you will need to find the item responsible for managing the device. From the action menu, select the option “Reset” or “Factory Reset”. The interface may differ depending on the version of the program, but the logic remains the same.
- 📱 The app allows you to reset the device even if it is hanging in the standard menu.
- 🔄 Available the function of forced reboot Bluetooth stack.
- ⚙️ You can clean the dial cache separately from the main system.
It is important to note that using third-party software requires care. Notify for Mi Band has many settings, and a random change in sync settings can cause the main Mi Fit to stop seeing the bracelet, in which case you will need to re-install the main application.
Why Mi Fit can't see the bracelet after third-party utilities?
Forced reset and reset of the hover device
The situation when Xiaomi Band 4 stops responding to touch and does not display the image is rare, but requires a specific approach. Unlike smartphones, trackers do not have a physical button that can be pinched to force restart.
If the screen is out and doesn't light up when you're connected to charging, try leaving the device on the charging dock for 30-40 minutes. Sometimes a deep discharge blocks the power controller and takes time to set the minimum voltage. If that doesn't work, you can try the "shaking" method of the connection.
To do this, you need to find the Mi Band 4 device in your smartphone's Bluetooth settings and select "Forget the device" or "Cancel pairing." Then turn off Bluetooth on your phone, put the tracker next to charging, and turn on Bluetooth back, often forcing the bracelet controller to step out of sleep mode.
| Symptoms. | Possible cause | Method of decision |
|---|---|---|
| Black screen, no reaction. | Deep battery discharge | Leave on charging for 1 hour |
| Hanging on the logo. | Firmware error | Reset via the Notify app |
| Not connecting to the phone. | The Bluetooth stack error | Forget the device in the OS settings |
⚠️ Warning: Do not attempt to disassemble the battery recovery tracker case if it just freezes, it will break the waterproofness and deprive you of warranties.
Solving synchronization problems after reset
Once you have completed a full reset of the Xiaomi Band 4, you may experience a situation where the smartphone does not see the tracker when trying to repair.This is often due to the fact that the phone has left “junk” from the previous connection in the memory.
To avoid this, before you connect, make sure to go to your smartphone’s Bluetooth settings. Find Mi Band 4 and click “Forget” or “Delete.” Only after you completely clean the list of associated devices can you start the setup process again.
It is also worth checking whether the Android or iOS security system blocks the Mi Fit application. Sometimes, after resetting the bracelet, you need to reissue all permissions to access geolocation and background work, without these permissions, stable communication is impossible.
💡
If the bracelet is not on the lookup, try rebooting the smartphone itself, which clears the Bluetooth cache and often solves the invisibility problem of the device.
In rare cases, installing the Mi Fit app on another smartphone helps, so you can see if the problem is in the tracker itself or in the software of your main phone, and if the other phone is working, the problem is with your device's operating system settings.
