How to untie Xiaomi smartphone from Mi Account: the complete guide

The problem of unbundling Xiaomi account (Mi Account) becomes relevant for thousands of users every year, most often when you buy a used device, sell your own gadget or lose a password from a cloud service. Mi Account is not just a profile for synchronizing contacts, but a serious security tool that blocks the device after resetting, if not previously deleted.

If you just reset your settings through a menu or Recovery, but don't follow the detachment procedure, your smartphone will turn into a brick with a lock activation screen. The system will require you to enter the username and password of the previous owner. In this article, we will discuss all the legal ways to solve the problem, from standard exit through settings to complex cases with forgotten data.

It's worth noting that modern versions of MIUI and HyperOS have strong protection against theft, so methods that offer "magic buttons" to bypass are often fraudulent. The only guaranteed way to unbundle is to access the owner's account or formally request support for checks. We'll look at working algorithms for different scenarios.

Why is the device detachment procedure necessary?

Many users underestimate the importance of logging out before flashing or selling. Activation Lock links unique hardware identifiers (IMEI, serial number) to a Xiaomi cloud account, so that in the event of a theft, an attacker cannot use the phone even after the memory is completely cleared.

When you sell a phone, the new owner will encounter a welcome screen where the system will require authorization. Without the previous administrator's correct credentials, the device will remain locked. Moreover, as long as the phone is listed with you, you are theoretically responsible for the actions taken from it if the account data was not deleted.

You also need to uncouple when you're handing over your device for repair or changing your main smartphone to a new model. If you don't remove it from your trusted list, you may have problems with two-factor authorization or data synchronization. The cloud service will consider the old device active, which can lead to file version conflicts.

⚠️ Warning: If you bought a phone with your hands and it's locked by someone else's account, no software resetting method will help forever. After each turn on, the device will ask for a password again.

Standard way of detachment through smartphone settings

If you have physical access to an unlocked smartphone and remember the password, the process takes only a couple of minutes, and it’s the most accurate and secure method to ensure that the device is completely clear of your data and ready for a new user.

To start, open the settings menu and find the account section. The path may vary slightly depending on the version of MIUI, but the logic remains the same. You need to find "Mi Account" or "Accounts and Sync."

Once you enter your profile, scroll to the bottom of the page, and there will be a red button for "Get Out" or "Delete Account" and the system will warn you that all data synced to the cloud (contacts, notes, voice recorder) will be deleted from the device, but will remain on the server. Confirm the action by entering a password.

• 📱 Go to Settings. → Mi Account.
• 🔻 Click the “Out” button at the bottom of the screen.
• 🔑 Enter the password from the account to confirm.
• ✅ Wait for the message of successful removal of the device from the cloud.

Once the operation is successful, the phone will no longer be tied to your ID. You can now safely perform Hard Reset or transfer the gadget to another person. If the system writes a network error, check the Internet connection, since the request for uncoupling goes to the manufacturer's servers.

Delete the device via the i.mi.com web interface

It gets even more complicated if the phone is lost, broken, or physically inaccessible, but you have to untie it from your account, and in this case, Xiaomi's cloud service comes to the rescue, and you'll need a computer or any other smartphone with Internet access and a browser.

Go to the official cloud service website. Sign in using your Mi ID (phone number or email), and when you log in, you'll see the main menu that displays all the devices that have ever been connected to that account.

Find the model you want to use. It usually shows the model name, the last IMEI digits, and the date of the last synchronization. It's going to have a control button or a gear icon next to it. You can select the "Delete" or "Untie" option. It'll require you to verify your identity through a text or email code.

It’s important to understand the difference: deleting through the site removes the activation lock, but does not erase the data from the phone itself (if it is not connected to the network at the time of the command). If the phone is in the hands of a thief, he can still see your data until he connects to the network and receives a command to wipe. However, for selling a used phone, this method is ideal if the device itself is already reset by a buyer.

Difficult cases: forgotten password or phone number

The most common problem is that the user does not remember the login data, and without a password, standard uncoupling is impossible, because it would violate the very concept of security, but there are several ways to solve it, depending on what data you have.

If you remember your login (email or phone) but you forgot your password, use the recovery function. On the login screen, click "Forgot your password?" The system will prompt you to send a confirmation code to your associated number or backup email, which is the fastest way to return access to your account.

If your phone number is lost or your SIM card is blocked, the process becomes complicated, you need to access your mailbox if it's listed as a backup, and if you lose both your phone and your mail, you only need to contact support.

• 🔄 Try to remember the alternative passwords you used before.
• 📧 Check your email archives for emails from Xiaomi with confirmation codes.
• 🆔 Prepare. IMEI Devices and purchase receipt for technical support.
• 📞 Contact the operator to restore the number, if possible.

⚠️ Warning: Do not try to match your password with brute force. After several unsuccessful attempts, your account will be temporarily blocked, and the waiting time between attempts will grow exponentially.

Call for Official Support for Xiaomi

When automatic recovery methods fail, the only legal thing is to have a dialogue with the manufacturer. Xiaomi's support team has tools to manually untie devices, but only if you prove ownership.

You need to find the original smartphone packaging and, most importantly, a cashier's check or invoice. The document should clearly show the date of purchase, the model of the device and its serial number (or IMEI). Low-quality photos of the check or screenshots from the online bank are often not accepted.

The application process is usually done via the form on the official website in the Service section or through the Service app, if available in your area, you will need to download scans of documents and describe the problem. The application processing period varies from 3 to 14 business days.

The company's employees verify the authenticity of the documents and check the IMEI against the database, and if everything matches, they force the device to untie the server-side account, and then the phone can be activated with any new profile.

💡

Keep a photo of the check in the cloud immediately after you buy the equipment. Paper checks often fade after a year, and it becomes impossible to prove the purchase.

What to do is categorically not worth doing

In pursuit of a solution, users often turn to questionable sources, the Internet is full of suggestions to “unlock Xiaomi in 5 minutes”, it is important to understand that most of these methods either do not work on current versions of firmware or carry serious risks.

Using third-party software, so-called “patchers” or “activators,” often leads to the installation of malicious code, such programs can contain Trojans that steal your bank card details and passwords from other services, and interference with system files can disrupt the bootloader and lead to a cyclical reboot.

Buying IMEI unlock services from gray wizards is also risky, often using stolen accounts or temporary exploits that are closed after a security update, and you may end up losing money and being left with your phone locked.

• ❌ Do not download programs to “hack” your Mi Account from unverified forums.
• ❌ Do not share your account information with third parties to help you».
• ❌ Do not try to reflash the device with global stock firmware versions on Chinese devices without unlocking the bootloader.
• ❌ Don’t ignore the lock, hoping it will disappear by itself.
