How to untie Xiaomi Mi Band from your account: 5 proven ways

The Xiaomi Mi Band fitness bracelets have become an integral part of the lives of millions of users, but sometimes it becomes necessary to untie the device from the account, for example, when selling a bracelet, changing a smartphone or switching to another Mi Account. The process seems simple, but many people face mistakes: the device does not untie through the application, requires a password from an old account or completely ceases to respond to commands.

In this article, we’ll look at all the possible ways to unblock, from standard deletion via Mi Fitness (formerly Mi Fit) to forced resetting. We’ll focus on the nuances for different models (Mi Band 3/4/5/6/7/8) and the typical errors that prevent you from successfully completing the process. If you plan to sell the bracelet or transfer it to another person, be sure to read the full reset section – this will ensure that the new owner does not encounter any problems with setting up.

Why do you need a Mi Band undress?

At first glance, the need to untie the bracelet from the account does not occur as often, but there are several situations where this becomes critical:

• 💰 Selling or transferring a wristband – the new owner will not be able to link the device to their account if it remains in your profile.
• 📱 Changing your smartphone or account – if you change your phone number or email to your Mi Account, your bracelet may lose sync.
• 🔄 Synchronization errors – sometimes data stops updating, and the only way to fix this is by re-binding.
• 🛡️ Security issues – if your account has been hacked, it’s best to untie all devices.
• 🆕 Update firmware – some versions of the software require re-authorization.

It’s important to understand that simply removing the bracelet from the list of devices in an app doesn’t always amount to a complete undoing. In some cases, the data stays on Xiaomi’s servers and the new owner won’t be able to activate the gadget. To avoid this, you need to perform a complete reset — more on this in the next section.

Method 1: Standard uncoupling through the Mi Fitness application

The easiest and most recommended way is to use the official Mi Fitness app (formerly Mi Fit), which works for all Mi Band models starting with version 3 and doesn't require resetting.

1. Open the Mi Fitness app on your smartphone.
2. Go to the Profile section → My devices.
3. Click on your Mi Band icon in the list.
4. Select Untie Device (or Remove Device in older versions of the app).
5. Confirm the action by clicking Untie in the pop-up window.

If it goes well, the bracelet will be removed from your account, but this does not guarantee complete deletion of data from the device.

Make sure the bracelet is gone from the list of devices|Reboot the Mi Band (click the 10 seconds button)|Check synchronization on the new device (if you transfer the bracelet)|Reset the settings on the bracelet (see Method 3)-->

⚠️ Warning: If the app is trying to untie the device, it may indicate that the bracelet is not currently connected to the phone:

• 🔌 Reconnect Mi Band via Bluetooth.
• 🔄 Re-launch the Mi Fitness app.
• 📱 Reboot your smartphone.

Method 2: Uncoupling through the web version of Mi Account

If you don't have access to the smartphone that the bracelet was tied to, or the Mi Fitness app doesn't work, you can try untie the device via the Mi Account web interface, which is less reliable, but sometimes helps in difficult situations.

For this:

1. Go to the Mi Account website and log in.
2. In the Devices section, find your Mi Band (it can be displayed as MIBAND or XMSH with model number).
3. Click on the three dots next to the device and select Remove.
4. Confirm the action by entering the password from the account.

⚠️ Note: This method does not always work for the Mi Band, as some models are tied to the account at the firmware level. If the bracelet is not tied to the new account after being deleted via the web interface, you will have to do a hardware reset (see Method 3).

Method 3: Completely reset the bracelet settings

If standard methods don't work, or if you want to completely erase all data before selling, you'll have to do a hard reset right on the device, and the procedure varies depending on the model:

Once reset, the bracelet will completely delete all steps, training and settings, and will unplug your Xiaomi account. Now it can be tied to a new phone without any problems.

• ⚠️ In the models with NFC (Mi Band 5 NFC, Mi Band 6 NFC) The reset will also remove tied bank cards.
• ⚠️ If the bracelet has been locked through Find Device, the reset will unlock it.

💡

If the bracelet does not turn on after reset, connect it to charging for 10-15 minutes. Sometimes the reset discharges the battery to a critical level.

Method 4: Uncoupling through Recovery Mode (for Advanced)

In the rare cases where the bracelet is locked or does not respond to standard methods, you can try the recovery mode, which is suitable for the Mi Band 4/5/6 and requires a connection to a PC.

You'll need:

• 🖥️ Computer with drivers installed ADB.
• 🔌 Mi Band connection cable (usually a modified connector charging cable is used).
• 📂 Firmware for your model (you can download on the forums).

Instructions:

1. Connect the bracelet to the PC via cable.
2. Open the command line and type: Adb devices Make sure the device is defined.
3. Transform the bracelet to Restore by Team: Adb Reboot Recovery
4. In the recovery menu, select Wipe Data/Factory Reset.
5. After resetting, reboot the bracelet: adb reboot

⚠️ Attention: This method is risky, because if you do the wrong thing, the bracelet can turn into a brick. Use it only if other methods have failed and you are confident in your skills. 7/8 Recovery mode can be blocked by the manufacturer.

💡

Recovery mode is a last resort, and in 90% of cases, a standard reset through the wristband menu or app is enough.

Frequent Mistakes and How to Avoid Them

Even when following instructions, users often encounter problems, and here are the most common mistakes and solutions:

Another common problem is that the bracelet is untied, but it's not tied to the new account, and this may be because of:

• 📵 Regional restrictions – some Mi Band models are tied to specific regions (e.g. Chinese versions).
• 🔄 Outdated firmware - update the bracelet software through Mi Fitness.
• 🛡️ Account Blocking – if a new Xiaomi account is not confirmed email/phone.

How to check if the bracelet is successfully untied?

Before you transfer the Mi Band to a new owner or link to another account, make sure the uncoupling is correct.

1. Check through the app: Open Mi Fitness and make sure the bracelet is not in the My Devices section. Try adding the bracelet again - if it is detected as a new device, the undocking is successful.
2. Check on the bracelet: After reset, the greeting animation should appear on the screen (as when you first turn on). All user settings (dials, notifications) should be reset to the factory.

Checking through another account:

• Sign in to Mi Fitness under another account and try to tie the bracelet.
• If the process is error-free, the device is completely free.

If you don’t know your old account, this method won’t work.
