How to untie the Xiaomi bracelet from your phone without access to your device and account

The situation when you need to untie the fitness tracker from the smartphone, but access to the phone itself or the Mi Account is not common. This can happen when you sell the device, transfer it to another user or in the case of losing an old smartphone with the installed Mi Fit or Zepp Life application. The problem is aggravated by the fact that the Xiaomi ecosystem is built on a rigid binding gadget to a particular account, which creates the illusion that it is impossible to solve the problem independently without the original host.

However, the technical limitations are not absolute. In most cases, Mi Band trackers store the pairing keys locally, and there are proven methods of forced disconnection. You do not need to be an expert in programming or have access to the company's servers. It is enough to consistently perform a series of actions that will clear the device's memory and return it to the factory state of settings.

In this guide, we will take a look at all the options available, from simply resetting the wristband itself through the menu to using third-party software. It is important to understand that the process can vary depending on the firmware version and the tracker model. We will look at the nuances of working with the Mi Band 4, 5, 6, 7 and 8, and also touch on the data security issues that remain on the device.

Why bracelet requires detachment and what is account locking

Many users don’t care about the device’s binding until they’re faced with the need to replace it. Mi Account (or Xiaomi account) serves not only to synchronize statistics, but also to protect against theft. When the tracker is tied, it gets a unique identifier in the cloud, and when you try to connect to a new phone, the system checks the owner’s rights.

If you try to connect a bracelet that is listed on another account, the application will give an error and require the authorization of the previous owner, a security mechanism that prevents unauthorized persons from using stolen or found devices, but if you forget the password from your account or the phone was lost without the ability to restore access, this mechanism becomes an obstacle for the legitimate owner.

⚠️ Note: Full uncoupling through Xiaomi servers without access to the account is impossible. All of the methods described below are aimed at locally resetting the device, which allows you to use it again, but the history of data in the cloud will remain unavailable.

There is also the concept of soft and hard binding: In older models, it was enough to simply forget the device in the Bluetooth settings, but modern versions of Zepp Life and Mi Fitness require exactly the unbind procedure within the application. Without this step, the bracelet can continue to try to synchronize with the background process of the old phone, blocking the connection to the new one.

Method of hardware reset via tracker menu

The most reliable and safe way to return the device to its original state is to use the built-in menu of the bracelet itself, which does not require a smartphone at hand and works even if the device is locked by an account. The algorithm of actions is the same for most models, starting with the Mi Band 4.

First, wake up the tracker screen and go to the main menu. Swipe left or right (depending on the model and firmware version) find the Settings section (the gear icon). Inside this section, you need to find the System or Reset item. Clicking on this item initiates the cleaning process.

Once the action is confirmed (usually you need to hold your finger on the screen or press the touch button), the device will restart, and it is important not to interrupt this process, at which point the internal storage is formatted, all pairing keys, alarm settings and activity profiles are removed.

• 🔄 On the Mi Band. 4/5 Path: Settings → System system → Unbind (untie) → Ok.
• 🔄 On the Mi Band. 6/7/8 Path: Settings → System system → Reset (Reset) → Confirmation.
• 🔄 Some firmware versions require a pin code if it was installed earlier.
• 🔄 After the reboot, the Mi logo will appear on the screen, and the bracelet will go into phone search mode.

It’s worth noting that this method doesn’t delete data from Xiaomi’s cloud account; it only makes the device a blank slate for a new connection, and if you want to sell the bracelet, it’s enough because the new owner can link it to their phone without any errors.

Use of third-party applications for forced decoupling

In cases where the bracelet menu is not available (hang, touchscreen damage) or a standard reset does not help, specialized utilities come to the rescue. Notify for Mi Band (formerly known as Notify & Fitness) is a powerful tool for owners of Xiaomi devices, which has rights that exceed the standard Mi Fit application.

To work with this method, you will need an Android smartphone (any, not necessarily your main one). Install the Notify for Mi Band app from Google Play. Once you start, scan the devices. Even if the bracelet is occupied by another phone, the utility often sees it and may try to establish a connection bypassing standard protocols.

In the app menu, find the Tools or Actions section, which should have Factory Reset or Unbind Device, which force you to break the connection and clear the memory, and is about 90% effective for models up to and including Mi Band 7.

If standard features don't work, there's a debugging mode in Notify for Mi Band. Go to the app's settings → Debugging → Commands. You can manually send them here. HEX-command to reboot Bluetooth service on the bracelet, which often results in resetting connection settings.

Specificity of the detachment for different models of Mi Band

Each generation of Xiaomi fitness trackers has its own firmware and hardware features that affect the detachment procedure. Mi Band 4 and 5 have a classic menu where the detachment point is deep in the system settings. These models often encounter a bug when the bracelet continues to "remember" the last device after reset.

With the release of Mi Band 6 and the transition to larger screens and new protocols BLE, But the sixth model had a screen lock feature (PIN-If the bracelet has a pin code, resetting through the menu will require entering it. Without the code, you can only untie the device through multiple incorrect password insertion (if such option is included in the firmware) or flashing it through the flashing device.

The Mi Band 7 and 8 models use RTOS, which manages power saving and connections more aggressively.Outsetting on these devices often requires a full battery drain after resetting to clear the volatile Bluetooth cache memory.Just rebooting may not be enough to completely remove encryption keys.

• 📱 Mi Band 4/5: Reset via the Unbind menu. Often requires repetition. 2-3 once.
• 📱 Mi Band 6: Strictly binding to Mi Account.Factory Reset reset is a must.
• 📱 Mi Band 7/8: Complete discharge after discharge is required for guaranteed cleaning.
• 📱 Mi Smart Band: Specific models (e.g., Mi Smart Band, NFC versions) may require resetting NFC-chip-off.

Global (Global) and Chinese (CN) versions may have different algorithms for detachment attempts. Chinese versions are sometimes more loyal to menu resets, while global versions follow Xiaomi server security protocols more strictly.

Problems with Bluetooth and cache on Android and iOS

Often the problem is not with the bracelet itself, but with the tails of the connection left in the phone's operating system. If you change your phone but try to untie the device, the old Bluetooth profile may interfere. → Bluetooth, find the device (e.g., "Mi Band") 5") and press Forget the device (Unpair/Forget).

On iOS (iPhone), the situation is similar, but Apple's system controls access more tightly. Go to Settings → Bluetooth, click on the icon (i) next to the bracelet and select Forget this device. After that, be sure to restart the smartphone itself to clear the system cache of Bluetooth services.

⚠️ Warning: Do not attempt to connect to the bracelet via the phone's standard Bluetooth menu until the application's unbundling procedure is complete.

If the bracelet is not removed from the list of paired devices, you can use the hidden engineer menu on Android. Enter the code ##4636## in the dialer (not all phones work), go to Bluetooth Test and follow the command Disconnect All or Clear Bonded Devices. This will forcefully remove all saved keys from the Bluetooth module.

💡

If the bracelet is visible in Bluetooth search but not connected, try connecting to it as an audio device (earphones).

What to do if nothing helps: extreme measures

In the rare cases where the software reset doesn't work, the menu is locked, and third-party apps can't see the device, the deep discharge method remains: leave the bracelet on next to the phone (so it tries to connect and waste energy) until the battery is completely depleted. When the device shuts down on its own, leave it lying down for 2-3 days.

Then, put the bracelet on charge. Many models automatically start the integrity check process when they turn on and can reset user data. This is not a guaranteed method, but it helps in situations where the software part is stuck in a binding error state.

If that didn’t work, the only solution is waiting. Xiaomi servers periodically clean inactive devices. If the bracelet has not been online for more than 30-60 days (depending on the model), the server can automatically revoke the authorization token, and the device will become available for new binding.

💡

Full discharge and long wait is the only way to “hardware” reset without the participation of software, based on the reset of the volatile memory of the controller.
