How to Untie and Reset Xiaomi Mi Band 2: The Complete Guide

Owners of Xiaomi fitness trackers often face the need to completely reset the device, especially when it comes to the Mi Band 2 model. This can be caused by the desire to sell the gadget, transfer it to another user or simply solve software errors that accumulate during long-term use. Understanding how to properly demolish or untie the tracker is a critical skill for any user of the ecosystem of smart devices.

The process of disconnection is not always obvious, as the device itself does not have a reset button or a screen from the settings menu. The entire management logic is hidden in the smartphone software and the specifics of the Bluetooth connection. Wrong actions can lead to the fact that the bracelet remains “locked” on the old account or ceases to respond to commands.

In this article, we will discuss in detail all available methods of deactivation and cleaning of the Mi Band 2. We will consider the standard methods through official applications, manual removal from the system settings of Android and iOS, as well as touch on the issues of firmware reflashing for advanced users. Competent approach will avoid problems with synchronization in the future.

Preparation for the tracker detachment procedure

Before proceeding with active action to delete data, you need to make sure the device is ready for the procedure.Mi Band 2 — It's an energy-efficient device, but an unstable battery charge can interrupt the process of synchronizing the latest data before resetting. 20-30%.

It's also important to understand what you lose when you completely reset, and all the accumulated steps, pulse, and sleep data that hasn't been synchronized with the cloud storage server will be permanently lost, so the first step should always be forced synchronization through the application.

Make sure your smartphone has Bluetooth and geolocation enabled, two modules that are essential for a stable connection to the tracker. If you plan to transfer the device to another person, let them know in advance that you will need to install a new app and create a separate account or link to yours.

Check the version of the app installed. Mi Band 2 has historically used Mi Fit (now Zepp Life), but some users still use older versions of the Mi Band or third-party clients like Notify for Mi Band. The interface may differ, but the logic of the actions remains similar.

Before reset, take a screenshot of your records or statistics if important to you, as once unset, the visualization of the story in the app may change.

Resetting with the Zepp Life app (Mi Fit)

The most correct and safe way to untie a fitness bracelet is to use official software. The Zepp Life app (formerly known as Mi Fit) implements a regular break-up mechanism that correctly clears the cache and sends a command to reset (pair) to the device itself.

To start, open the app and go to the Profile tab. Find your Mi Band 2 in the device list. Click on the device name and you'll be taken to the tracker settings menu, and scroll down to the bottom of the list, where the Unlink or Ununlink button is usually located.

⚠️ Attention: Pressing the Untie button in the app doesn't always completely clear the data inside the bracelet's memory, but it breaks the encryption keys.This may not be enough to sell fully, additional cleaning is required.

Once confirmed, the app will try to contact the tracker. The bracelet screen may blink or vibrate to confirm the receipt of the command. If the communication is stable, the device will go into the connection standby mode, displaying the time or Bluetooth icon with cross-out.

It is important to note that after this procedure, the activity history of the app will be stored in your account, but new data from this particular device will no longer be received, which is ideal if you just change your phone, but keep the bracelet for yourself.

Manual removal via Bluetooth settings

Sometimes, software resets through an application are not possible because of synchronization errors or the “hang” of the Bluetooth service, in which case intervention at the level of the smartphone operating system is necessary, which allows you to forcibly break the connection, ignoring the commands of the tracker application itself.

Go to the basic settings of your smartphone and select the Bluetooth section. In the list of available and paired devices, find the record Mi Band 2 or MI Band 2. Click on the gear icon or make a long tap (depending on the version of Android or iOS) to open the device control menu.

Select the option “Forget device” or “Unpair pairing” and the system will warn you that all connection data will be deleted. Confirm action. Now the smartphone no longer sees the bracelet as a trusted device, and automatic connection is impossible.

However, this method has a nuance: the bracelet itself can “think” that it is still connected until the connection timeout expires. So after removing from the Bluetooth settings, it is recommended to restart the smartphone and only then try to re-find the device to link to a new account.

Using third-party utilities for deep cleaning

For users who want to get the most control over their gadget, there are powerful third-party tools, and one of the most popular is the Notify for Mi Band app, which allows not only to track notifications, but also to perform a deep reset of the Mi Band 2 settings.

Unlike the standard application, utilities like Notify have access to low-level Bluetooth Low Energy (BLE) commands, which allows you to send specific data packets that initiate a full factory reset if this feature is supported by the device’s firmware.

To use this method, install the application, pair and go to the "Device Management" or "Brecelet settings" section, where you should look for options related to "Reset" or "Reset." Be careful: using untested features can lead to unstable work.

⚠️ Warning: Third-party apps may request advanced permissions. Use only proven utilities from official stores to avoid leaking data about your activity and health.

The advantage of this approach is that it often helps to revive the bracelets that no longer respond to the commands of the official application, which is a kind of resuscitation of the device by software methods before selling or disposing of.

Flashing procedure and_hard_ discharge

In rare cases, when software methods don’t help, or if you want to completely change the region of the device (for example, from Chinese to global), you may need to flash it.For the Mi Band 2, it’s a complicated procedure, since the device does not have a USB port and a screen to select files.

The firmware process usually requires a special bootloader and firmware file (format.bin or.fw).The user must place the firmware file in a specific directory on the smartphone or use a modified application that can "fill" new code directly through Bluetooth.

During firmware, the bracelet screen can go out and light up, and vibration can work in emergency mode. Interrupting the process at this stage can turn the Mi Band 2 into a “brick” that cannot be turned on without a special programmer.

The path to firmware files (an example for Android):


/Android/data/com.xiaomi.hm.health/files/update/

If you are not an experienced user and do not understand the risks associated with flashing devices, it is better to refrain from this method.

Solving problems when uncoupling the device

A common problem is when the bracelet is not untied or constantly trying to reconnect to an old phone, this can be due to cached data in the Android or iOS system, in which case you need to clean the data of the application itself.

Go to your smartphone settings, find the Apps section, select Zepp Life (or the tracker you use), and click Storage. Select the Clear Data and Clear Cache option, which will return the app to state immediately after installation.

Phantom connections can be another cause of problems: Bluetooth settings sometimes leave records of old devices with the same name, and delete any records containing "Mi Band" or "MI" to rule out MAC address conflicts.

If nothing works, try the "cold" reboot method of the bracelet. Put the Mi Band 2 on the charger connected to the bracelet. USB-You can also use the port of your computer (not powerbank, but the port of your PC for stability), and wait until it vibrates. Sometimes, a connection to a power source resets the Bluetooth module.

💡

The most common mistake is trying to tie the bracelet to a new phone without first removing it from the Bluetooth memory of an old smartphone.
