How to untie Mi Band from Xiaomi account: 5 proven ways (including complex cases)

Why you can’t just remove the bracelet from the app and what to do next

Uncoupling the Xiaomi Mi Band from a Xiaomi account only seems like a simple procedure – in practice, users face a lot of pitfalls. The main problem is that even after removing the device from the Mi Fitness app (formerly Mi Fit), the bracelet can remain tied to the old Mi Account at the firmware level, which blocks the ability to connect to a new account or smartphone, and in some cases makes the device completely inoperable.

The situation becomes more complicated if you:

  • πŸ”„ Buy a used bracelet with a link to someone else's account
  • πŸ“± Changed smartphone and lost access to the old Mi Account
  • πŸ”’ Forgot the password from the Xiaomi account, which is tied to the bracelet
  • πŸ› οΈ Updated the firmware of the bracelet, after which it stopped synchronizing

In this article, we will discuss all the current ways of detachment - from standard (via the application) to emergency (hardware reset and bypass Mi Account lock). Particular attention will be paid to the Mi Band 5/6/7/8 models, where Xiaomi has tightened protection against unauthorized reset. If your bracelet is locked after updating or requires login / password from an old account - here you will find a solution.

⚠️ Note: Some methods (e.g., discharge through ADB If the bracelet is warranty, contact Xiaomi Service Center first.

Method 1: Standard unbundling via the Mi Fitness app (for working accounts)

If you have access to the Mi Account that the bracelet is attached to, and the device syncs normally with your smartphone, use the official method. This is the safest and fastest way, and does not require technical skills.

The instructions are relevant for the Mi Fitness app (version 5.0 and later) on Android and iOS:

  1. Open the Mi Fitness app and make sure the bracelet is plugged in (the device icon is active at the top of the screen).
  2. Go to the profile (I β†’ My devices).
  3. Find your Mi Band on the list and tap it.
  4. In the menu that opens, select Untie the device (or Remove the device in older versions).
  5. Confirm the action, wait for the process to be completed (the bracelet vibrates).

Once untie, the bracelet will automatically reset, and it can now be linked to another account or smartphone through a standard pairing procedure.

Check the bracelet connection to your phone via Bluetooth

Update the Mi Fitness app to the latest version

Reboot your smartphone and bracelet (on Mi Band 5/6/7, press the touch button for 10 seconds)

Make sure you have a stable internet connection (uncoupling requires synchronization with Xiaomi servers)-->

⚠️ Warning: If the bracelet requests a login/password from the old account when it reconnects, the reset was incorrect.

Method 2: Hardware reset Mi Band to factory settings (Hard Reset)

If the standard uncoupling didn’t work or you don’t have access to your old account, try a full reset, which works on all Mi Band models, but newer versions (starting with the Mi Band 5) may require additional action.

Resetting instructions:

Model braceletButton combinationNotes
Mi Band 1/2/3Press the touch button for 10-15 seconds until vibrations appear.After resetting the bracelet will automatically reset.
Mi Band 4Press the touch button for 20 seconds, then release and immediately press for another 5 seconds.On the screen will appear the inscription Reset or tick
Mi Band 5/6/7/8Press the touch button for 30+ seconds until the Mi logo appears.New models may require confirmation through QR-code

Once reset, the bracelet should return to factory settings. However, on Mi Band 5 and later, there is a common problem: the device requires data input from the old Mi Account even after Hard Reset. This involves firmware-level binding, in which case move to the ADB method.

πŸ’‘

If the bracelet does not respond to the pressing of the button, connect it to the charger and try again. On some models, reset is possible only at a charge level above 20%.

Method 3: Uncoupling through ADB (for advanced users)

If the hardware reset didn’t work and the bracelet still requires the old account data, you can try removing the anchor via ADB (Android Debug Bridge), which only works on Android smartphones and requires the developer mode to be enabled.

Step-by-step:

  1. Activate Developer Mode on your smartphone: Go to Settings β†’ About Phone. Tap 7 times on Build Number. Go back to Settings β†’ System β†’ Developer. Enable USB Debugging.

ADB Tools

CMD

ADB

adb devices

(Your device should appear)

adb shell
pm clear com.xiaomi.hm.health
pm uninstall -k --user 0 com.xiaomi.hm.health

Mi Fitness

This method removes all of the Mi Fitness app data, including the device-binding cache, and after reinstalling the app, the bracelet must connect as a new device, but on the Mi Band 7/8, this method doesn't always work because of the tightened protection.

What if the ADB can’t see the device?
Make sure that the drivers for your smartphone are installed (download from the manufacturer's website). USB-cable (not all cables support data transfer) Enable "Allow debugging by debugging" in the developer settings USB (Safe Mode)" Restart your PC and smartphone, then reconnect.

Method 4: Bypassing the lock Mi Account through firmware (for locked bracelets)

If the bracelet requires a username/password from an old Xiaomi account after reset, and you can’t contact the previous owner, only the firmware remains through informal tools, a risky method (which can lead to the β€œbricking” of the device), but often the only solution.

You'll need:

  • πŸ–₯️ Windows computer (for Mi Band) 3/4/5) or Mac/Linux (new-model)
  • πŸ”Œ Firmware cable (for Mi Band 1-4 you need a special adapter)
  • πŸ“ Firmware for your model (download only from trusted sources, for example, XDA Developers)
  • πŸ› οΈ Firmware: MiBandTools (for older models) or AmazfitFirmware (for newer models)

Example of firmware for Mi Band 5:

  1. Download the archive with the firmware and unpack it.
  2. Connect the bracelet to the PC through a charging cable (on some models you need to close the contacts).
  3. Launch the file. flash.bat (for Windows) or run the command in the terminal: python mi_band_flasher.py --device COM3 --firmware firmware.bin (substitute COM3 to your port and firmware.bin filename).
  4. Wait until the process is complete (the bracelet will reboot several times).

⚠️ Warning: Unofficial firmware voids warranty and may cause an unstable bracelet to function. 7/8 This method rarely works due to the hardware protection.

πŸ’‘

Before you run the firmware, make sure to check the file compatibility with your bracelet model. Installing firmware from another version (for example, for Mi Band 5 on Mi Band 6) will lead to a breakdown.

Method 5: Calling for Xiaomi Support (official method for locked devices)

If all previous methods failed and the bracelet is blocked on someone else’s account, only official unlocking via Xiaomi support remains, which takes 3 to 30 days, but is guaranteed to remove the lock without risk to the device.

How to make a request:

  1. Go to the Mi Account website and log in (or create a new account).
  2. In the Support section, select Unlock the device.
  3. Fill in the form by specifying: Bracelet model (Mi Band 5, Mi Band 6, etc.) Serial number (located on the box or under the charging contacts) Reason for unlocking (for example, "buyed used, the previous owner did not untidy") Check or photo of the box (if any)

Send a request and wait for a response (usually arrives by email within 3-7 days).

If the bracelet has been stolen or blocked on suspicion of fraud, Xiaomi may request additional documents (such as a purchase check or a passport photo). 90% of the time, unlocking is successful, but on the Mi Band 7/8 the process can be delayed due to enhanced protection.

πŸ’‘ Useful tip: If you buy a used bracelet, always ask the seller to untie it from your account in front of you. Ask to show the process in the Mi Fitness app - this will save you problems in the future.
