Modern Xiaomi smartphones are equipped with a powerful security system Mi Cloud, which is closely related to your personal phone number. Often users are faced with a situation when after resetting, buying a used device or changing the phone. SIM-The system insists on confirming the number by blocking access to basic functions, not just a whim of the manufacturer, but a mechanism for protection against theft, known as theft. FRP (Factory Reset Protection).
However, there are times when a legitimate owner is locked outside of their gadget because of a forgotten password or a lost SIM card. The process of unlocking and unblocking an old number can seem like a complex maze of menus and technical requirements. In this article, we will analyze proven methods of solving the problem, explain the nature of the binding, and provide step-by-step algorithms for various versions of the MIUI and HyperOS shell.
Ignoring the system requirements or trying to circumvent them by dubious methods can lead to a complete lock of the device by IMEI. So it is extremely important to understand the difference between a simple change of number in the settings and the procedure for unbundling the Mi Account, which is stored on the company's servers. We will consider both standard methods through the smartphone menu and options for losing access to the SIM card.
Causes of blocking and protection mechanism
The main reason for requesting confirmation is because of Android security called Google FRP and Xiaomi’s proprietary protection, which means that when you first turn on your phone and enter your Mi Account details, the device “remembers” that account and the number associated with it. If you then complete a Hard Reset without first logging out of your account, the next time you turn on, the phone will require authorization from the last owner.
This is done so that in the event of a theft, an attacker cannot simply reflash the phone and use it as a new one, and the system locks the device until the correct password is entered or received. SMS-Without this step, the phone becomes a brick with limited functionality available only for emergency calls.
⚠️ Warning: If you bought a phone with your hands and you turn on and you see a lock screen with someone else's account, it's almost impossible to bring the device back to life on your own.
Often users confuse activation blocking with conventional two-factor authorization. In the first case, access to the system is completely closed, in the second case, only confirmation of login to a particular application or service is required. Understanding this difference is critical to choosing the right method of solving the problem. If the phone requires code right on the boot start screen, this is the level of FRP protection.
Staff untied number through smartphone settings
If you have physical access to your smartphone menu and you know the password from your Mi Account, but you just want to change the number or remove the binding for sale, the procedure is done by regular means. This is the most secure method that does not violate the warranty and does not require the use of third-party software. Before you start, make sure that the device is connected to a stable Wi-Fi network.
To start, go to the settings section and find the account item. The path may vary slightly depending on the firmware version, but the logic remains the same. You need to find an active Mi Account and initiate the exit process. It is exiting the account before resetting the settings that is the key action to prevent future locks.
☑️ Preparing for account untiing
Once logged in, the system can request a reauthorization or confirmation via SMS. This is Xiaomi's standard security procedure. If you plan to sell a phone, be sure to wait for the message that the device has been successfully uncoupled from the server.
- 📱 Open Settings and go to Accounts and Sync (or Mi Account).
- 🔓 Click on your profile and select the option to exit or delete your account.
- 🔢 Enter the password and confirm the entry code from SMS, If the system requires verification of the number.
- ✅ Wait for the message "Account deleted" before performing any other actions.
It is important to note that a simple replacement SIM-The Xiaomi server stores the history of the bindings, and for complete cleaning, it is necessary to do the "Out" action, which sends a signal to the server about the change in the status of the device. Ignoring this step will result in a lock screen after the reboot.
What to do if SIM-card lost or unavailable
The most difficult situation is when the number to which the account is linked no longer belongs to you: the SIM card is lost, burned or the number is reissued by the operator. SMS-However, Xiaomi has provided alternative ways to verify the identity of the owner through backup email addresses or answers to security questions if they were set up in advance.
The first step is to restore access to the Mi Account itself through the official website, you'll need a computer or another smartphone, go to the account management page and select the password recovery option, and if you had a backup email attached, the confirmation code will come there, which will reset the password and therefore access the management of the associated devices.
If you don't have backup protection, it gets complicated, you have to go through the verification process through support, which is a long process, requiring receipts for the purchase of the device, a box with an IMEI code and a passport, without proof of ownership, you can't officially unlock the device, which is a direct consequence of security policy.
Alternative Verification Methods
There is a myth that the installation of a new SIM-A card with the same number (restored from the operator) will solve the problem instantly, and it only works if the operator has kept your old number. SIM-The map will not help, as the Xiaomi database contains the old digital ID.
Use i.mi.com for remote management
Xiaomi’s official cloud service provides a powerful tool for managing devices that is often overlooked. i.mi.com allows you to not only track the location of your phone, but also remove attached devices from your trusted list, which is equivalent to leaving your account on your smartphone, but is done remotely.
You still need access to your account (login and password) to use this method. If you remember the data but can't log in to your phone because you don't have a network or interface glitches, the site becomes a lifesaver. Log in to your profile, find the Devices section, and select the problem smartphone.
| Action on the site | The result on the device | Conditions required |
|---|---|---|
| Remove the device | Removes activation blockage (FRP) | Internet access on the phone |
| Erase the data | Full reset (Wipe Data) | Geolocation enabled |
| Disappearance regime | Blocking the screen with a message | Active connection to the server |
Once you select the option to delete the device, the server sends a command to the smartphone, if the phone is online, it will receive a signal and unplug the account. Critical: after this procedure, the phone must be rebooted, and only then perform a reset if planned. Direct reset without prior decoupling through the site may not work if the phone does not have time to synchronize status.
The site interface may not always be stable, so if the Delete button is inactive, try changing your account password first. This action forcibly terminates all active sessions and can help reset the suspended anchor status. However, remember that changing your password requires confirmation through an old number or email.
Resetting FRP and bypassing activation blocking
In cases where access to an account is lost completely and recovery is impossible, users often look for ways to bypass FRP blocking. It is worth noting that there are no official methods for this. All available solutions are temporary security vulnerabilities in Android, which Xiaomi and Google regularly close in updates.
One common but risky method is to exploit vulnerabilities in the feature menu or through the TalkBack browser, whereby you can use voice assistant or accessibility settings to call the system menu to run a third-party app or go to the full system settings, and you can add a new Google account to "peretrate" the old one.
💡
Use only proven FRP reset tools, such as the Mi Flash Tool combined with official firmware. Third-party "debtors" often contain viruses or miners.
A more complex but effective method is to run the device through Fastboot mode using an authorized account. However, for Xiaomi phones, this requires an unlocked bootloader, which, ironically, cannot be unlocked without access to the associated Mi Account, creating a vicious circle that can only be broken by contacting an authorized service center with documents.
- ⚙️ Attempt to log in via accessibility settings (TalkBack) to call the browser.
- 🌐 Using vulnerabilities in Google apps to change your account.
- 💻 Flip-through EDL Regime (requires an authorized service center account).
- 🛠 Contacting paid unlock services (risky and not always effective).
It's important to understand that with every Android security update (Google Security Patch patches), the number of ways to get around is reduced. What worked on MIUI 12 is likely not going to work on MIUI 14 or HyperOS. So relying on the "magic buttons" from the Internet is not worth it - there is a high risk of permanently locking the device.
Prevention of problems with number binding
To avoid a locked phone situation, you need to follow simple digital hygiene rules when using Xiaomi devices. The main recommendation is to always log out before selling, gifting or getting repaired. This takes one minute, but saves hours of hassle in the future.
It is also critical to add alternative recovery options: In the Mi Account security settings, specify a backup email that you will not lose, and set up complex control questions. Don't rely on SMS alone, as SIM cards tend to fail or get lost.
Check your account's trusted device list regularly. If you see old phones you're not using anymore, delete them. Not only does this free up the limit of your attached devices, but it also increases the overall security of your digital profile. A clean list of devices ensures that you know which gadget might be on which device to sign in.
⚠️ Warning: Never buy used Xiaomi phones if the seller refuses to demonstrate the process of logging out and resetting settings with you.
In the Android world, and especially in the Xiaomi ecosystem, having an original IMEI-painted package and a check from the store is the only proof of your ownership, and without these documents, even a service center can refuse to unlock it, considering the device stolen.
