When buying a used Xiaomi smartphone or returning the device after repair, it is critical to make sure that the previous owner has completely untied the device from his Mi Account. Unlike many other Android smartphones, the Xiaomi ecosystem has a rigid protection system known as Mi Cloud Lock, which blocks the use of the gadget even after completely resetting the settings to factory.
If the device was not properly untied, the new owner will encounter an activation screen that requires the previous user to enter the password, making the phone almost useless. In this article, we will examine in detail all the existing methods of checking the status of the binding, from visual inspection of settings to technical methods of checking through IMEI.
Ignoring this stage can lead to serious financial losses, as official unlocking methods often require purchase checks or the participation of the original owner, so checking the status of the account is the first and most important step in a transaction with used technology.
Visual status check in system settings
The easiest and fastest way to determine if a smartphone is linked to a cloud service is to manually inspect the settings menu. If you have access to the device’s desktop, you should immediately go to Settings and find the Mi Account, which is usually located at the top of the list or in the Passwords and Security section.
In the window that opens, you'll see the email address that the device is attached to, and if it's a different address or a plug, it's a direct signal that the phone isn't untied, and even if the vendor says "I just forgot to get out," it means that the locking mechanism is active and will work the first time you try to reset or flash it.
Special attention should be paid to the status of the device's search functions. Often users turn off sync but forget to deactivate the search, which leaves a back door for blocking.
- 🔍 Device search – must be turned off (slider in inactive state).
- 📡 Data transfer – make sure that the synchronization of contacts and gallery is stopped.
- 📍 Geolocation – Check if Mi Find has access to the location right now.
If the menu shows you a suggestion to log in or create a new account, it is a good sign, but it does not guarantee a complete cleanup of the servers. Sometimes the system caches data, and a full verification requires deeper actions, which we will discuss below.
💡
When buying used Xiaomi, always ask the seller to log out of your Mi Account through the settings menu, rather than just resetting with buttons.
Checking through a complete data reset (Hard Reset)
The only way to get a 100% guarantee that the smartphone is uncoupled from the Mi Cloud is to force the lock activation, which is done by performing a full Hard Reset via Recovery mode, at which point the device accesses Xiaomi servers to verify status.
To perform the check, turn off your phone and press the Volume Up + Power key combination before the logo appears. From the Recovery menu, select a language (usually English or Chinese) and press Wipe Data, then confirm the action of Wipe All Data. After the process, select Reboot.
☑️ Algorithm for resetting
Once you restart, the phone will start setting up the initial setup, and when you connect to Wi-Fi, the system will automatically check. IMEI-If the phone is untied correctly, you will go to the desktop, and if the link remains, the system will require you to enter the password from the Mi Account to which the device was previously associated.
⚠️ Note: This procedure will completely remove all data from your phone, and if you check your own device, save important photos and contacts beforehand.
This is the litmus test for all used devices, and many unscrupulous sellers simply delete their account from their settings, but they don't leave it thinking that's enough, and only a reset will show the truth.
Use the official Mi Cloud site to check
If you don’t have physical access to your phone, but you know the username and password of your Mi Account (for example, you buy a phone from a friend and he gives you access), you can check the status of the device remotely.
Log on a computer or other smartphone, log in to the account to which the phone you're checking is linked, and in the cloud interface, select Find Device, which will show you a list of all the gadgets currently connected to that account.
If the list contains a model of the phone being sold, it means that it is actively tied, the owner must click on the device icon and select the "Unlock" or "Delete from the list" function to untie it, only after the device disappears from the list on the site can the procedure be considered complete.
| Status on the site | Meaning | Action |
|---|---|---|
| Device on the list | Phone tied and tracked | Removal by the owner is required |
| The device is not on the list. | Retirement removed or device offline | Checking by discharge is required |
| Offline status. | Phone's not coming online. | The risk of blocking remains |

Verification through IMEI and service codes
A more technical but less reliable method is to check through an engineering menu or service code, although they do not always show the status of cloud anchorage directly. IMEI-code (located on the box or under the battery, as well as in the code *#06#), you can try to find out the status of the device through third-party services or the Xiaomi database.
In some versions of the firmware MIUI HyperOS in the About Phone section -> All parameters -> Status SIM-You can see the line "Mi Account Lock" if it's "Enabled" or "On", it means that the lock is active, but this line is often hidden or does not display the real state until the moment of reset.
There are also paid IMEI verification services that aggregate Find Device status data, which are query-based to activation servers, and type IMEI into the verification field, and the system will report:
- 🟢 Clean – the device is clean, not listed in the lost.
- 🔴 Lost/Stolen – Device marked as stolen.
- 🔵 Bound – the device is tied to the account, you need an uncoupling.
Remember that no service will give 100% guarantee other than an official reset.Databases can be updated with a delay, and the status of "Clean" may change within minutes of checking if the owner decides to lock the phone remotely.
Specifics of the block depending on the region
It is important to understand that Xiaomi’s security policy varies depending on the region for which the firmware is released. Global ROMs have the most stringent checks, while Chinese versions (China ROM) may behave differently, but the principle of operation of the Mi Cloud Lock remains the same for all.
If you purchase a phone imported from China and plan to reflash it to a global version, the risk of getting blocked increases. If you change regional firmware (for example, from CN to Global), the security system may consider this as suspicious activity and request confirmation of the owner.
And then there's Regional Locks, which are activated when you first turn on a phone in a region other than the intended market. For example, if a phone in India turns on in Europe, it can lock. It's not exactly Mi Account lock, but the problem is similar, the phone turns into a brick before it's unlocked through a service center or entered a code.
⚠️ Note: Buying phones with Chinese firmware (China) ROM) For use outside China, there are always risks. Make sure the seller confirms that the bootloader can be unlocked and the region can be changed.
Owners of these devices should be especially careful when checking, and even if the phone is untied from the account, regional linking can come as a surprise when you first install it. SIM-mapping.
What to do if your phone is blocked
If after checking it is found that Xiaomi is untied from the account formally, but when you turn on requires a password, the situation is unpleasant, but solvable. The first and most correct step is to contact the seller. Honest sellers usually go to meet and help unlock the device by entering the password remotely or in person.
If communication with the seller is not possible, the only hope is that checks and a box are available. Xiaomi's official support can unlock the device when providing proof of purchase (an IMEI check) and passport.The process takes from days to weeks and requires scans of documents to be sent.
💡
Never buy a Xiaomi phone without a box and a check unless you have done a full reset check before payment.
There are also informal Bypass methods, which are often offered in service centers, based on vulnerabilities in the bootloader or system files.
- 🚫 No guarantees – after restarting, the lock may return.
- 📉 Unstable work – calls, camera or notifications may not work.
- 🔒 Impossibility of updating - firmware will not be updated so that the bypass does not fly off.
So the best way to "treat" is to prevent it, and to check carefully before you buy it saves you nerves and money, and don't believe the word "you can reset your account in the service," because official services don't unblock Mi Clouds without documents.
