When a message β€œcouldn’t unlock xiaomi” appears on a smartphone screen, it can cause panic even in an experienced user. This error means that the authorization server cannot confirm the owner’s rights to unlock the device, which often happens after resetting or flashing. The smartphone turns into a β€œbrick” only conditionally, since access to the system is limited to a software blocker that requires confirmation through a Mi Account.

The reasons for this lock can be various factors, from a forgotten password to linking the device to someone else's account when buying from hand. Xiaomi has implemented this protection system to make it difficult to use stolen gadgets, but sometimes honest users become victims. It is important to understand that you can not ignore the request of the system, since the phone can be permanently locked after a certain time.

Reasons for the message about the impossibility of unlocking

Understanding the root of the problem is half the solution. The couldn't unlock error most often occurs when you try to boot the operating system after cleaning the data. It's a security mechanism that checks the status of the device in the manufacturer's global database. If the status indicates that there is an active lock, the download is interrupted.

A common reason is to buy a previously used device without due diligence, the seller may not have untied his Mi Account, and the security system regards your login attempts as unauthorized, and the problem arises when you try to unlock the bootloader without first linking the device to the account for 7 or 168 hours.

Technical failures on the server side of Xiaomi should also not be excluded: during periods of high load or maintenance, the authorization service may temporarily not respond to requests from devices, in which case the error message is temporary, but requires the correct algorithm of actions to correct it.

⚠️ Warning: Repeatedly entering the wrong password can lead to a temporary lock of the account for 24 hours or more.

Preparation for the procedure for restoring access

Make sure your PC has up-to-date drivers for Android devices and specifically for Xiaomi. Often the system doesn't see the phone in boot mode precisely because of the lack of necessary components.

The official method of unlocking through Mi Unlock Tool

The most reliable way to fix the bug is to use the official Mi Unlock Tool, a tool designed specifically for interaction with the company's security servers. First, download the latest version of the program from the official website and install it on your computer.

Run your phone in Fastboot mode. This usually requires you to press down and power down simultaneously before you see an image of a hare repairing an android. Connect the device to your PC and start the program by logging into your Mi Account.

If the device is tied to your account, the program will suggest unlocking it. If you connect successfully, you'll see the Unlock button. The process can take anywhere from a few minutes to a few days, depending on the status of the binding, and the program will automatically check the device on the server and remove the restriction.

However, manually entering commands through the ADB/Fastboot console without using the Mi Unlock Tool GUI is not recommended for beginners, since the syntax of commands can vary depending on the processor model and firmware version.

Comparison of methods of removing the lock

There are several approaches to solving a problem, each with its own characteristics, risks and requirements, and the choice of method depends on the specific situation: do you know the password, do you have access to it? SIM-How popular is the device model.

The table below shows a comparison of the main ways to choose the best one for your case, and pay attention to the level of risk of data loss and the need for special equipment.

Mi Unlock ToolAccess to the account, PCHigh (full discharge)Low.
Reset via RecoveryPassword from the accountTotal loss.Medium
Service centreCheck, box, passport.No (usually)Low.
Third-party servicesPayment for servicesHigh-pitchedTall.

Using third-party paid services (so-called remote anloc) carries additional risks: you transfer control of the device to third parties, which may compromise your personal information.

Actions with a forgotten password from Mi Account

If a couldn't unlock message appears because you don't remember your account password, things get complicated.The standard recovery procedure is via email or phone number, the only way to go. Go to i.mi.com and select the access recovery option.

You will need access to the phone number that was listed during registration, and an SMS will come with a confirmation code, and if the number is lost or the SIM card is not active, the recovery process may take a long time and require scans of documents confirming ownership of the account.

Once you've successfully recovered your password, don't rush to unlock your phone right away. Wait 24 hours. This is a security measure that prevents an attacker from immediately unlocking the device after an account is hacked, and only after that time, the server will allow the unlocking procedure.

⚠️ Note: Using bypass software for a Mi Account often results in the failure of basic phone functions such as camera, calls or mobile Internet.

Problems with regional versions and Global ROM

A special category is those purchased in China (CN Version) with Global ROM installed, where bootloader locking can be unpredictable, and a couldn't unlock error here can mean that the firmware region and the account region are incompatible.

If you have reflashed a Chinese phone to the global version without officially unlocking the bootloader (via EDL mode), then when you reset the settings, you are guaranteed to receive an authorization request. It will be difficult to go back to Chinese firmware in this case without an authorized Mi Account with a high level of security clearance.

Owners of such devices are advised to be extremely careful when updating the system. Trying to upgrade the "Chinese" with global firmware over the air (OTA) often leads to a cyclical reboot or lock screens.

When it is necessary to contact the service center

There are times when doing it yourself doesn't work, and if you're the first person to own a device, you have checks, you have a box, you have documents, but you can't unlock the phone, and the best thing to do is to go to an authorized service center.

The service has access to special tools and databases that allow you to unblock when confirming ownership, this is especially true if the account was blocked by the security system due to suspicious activity or if the device was lost and found.

Professional help is also needed if the system partitions are damaged during the self-unlocking process, and attempts to continue experimenting in this case can lead to a complete failure of the board, which will require expensive repairs or replacement of the motherboard.
