When a Xiaomi smartphone stops responding to a fingerprint or you forget a pattern lock, it can happen suddenly, because of software failures, scanner damage, or user inattention. Device owners often find that standard password input methods are not available.
Recovery requires understanding the security architecture of Android and the MIUI shell. Not all methods are universal, and effectiveness depends on the version of the operating system and the status of the account.
There are several proven methods to solve the lock problem, some of which require prior training, others work hot. In this article, we will discuss in detail how to circumvent the imprint on Xiaomi using regular tools and specialized tools.
Using a Mi Account to Unblock
The most legal and secure way to restore access is by linking to the manufacturer's cloud service, so if the device has the Internet on and is logged in to Mi Account, the system allows you to remotely reset the screen lock, which works even if you forget the digital code.
First, you need to go to the official cloud.mi.com website from any other device (computer or smartphone), enter your credentials that were used on the locked gadget, and after authorization, the system will suggest finding the device on the map.
Choose the right model from the list of available devices. The control menu will have options such as "Sound", "Block" and "Clean up." We're interested in the deletion feature, which will reset the screen password along with the contents of the internal memory.
β οΈ Warning: Cleaning your device through your Mi Account will permanently delete all photos, contacts and apps not stored in the cloud.
Once the reset command is executed, the phone must restart, if the device was online at the time the command was sent, the lock will disappear, otherwise the command will be executed when it first connects to the network.
π‘
Make sure that the date and time on the device you log in to your account is set correctly, otherwise sync errors with the Xiaomi server may occur.
The effectiveness of this method depends on the security settings that were active before the lock, and if the Find Device function was disabled, this method will not work.
Resetting settings via Recovery Mode
If you canβt access cloud services, you have to resort to hardware reset. Recovery mode is built into the firmware of each Xiaomi smartphone and allows you to perform system operations without booting the operating system.
To enter this mode, you need to turn off your smartphone completely. Then press the volume button and the power button at the same time. Hold them until the Mi logo or language selection menu appears.
βοΈ Preparation for Hard Reset
In the Recovery menu, you can navigate with volume buttons and choose with a power button (or touch the screen if the touch is working). Select Wipe Data, then Wipe All Data, and confirm the action.
The formatting process can take a few minutes. Once it's done, select Reboot to restart the system. The device will start as new, requiring initial setup.
β οΈ Note: On the modern versions MIUI after resetting via Recovery, you will need to enter a password from the Mi Account that was synchronized earlier (anti-Theft protection).
This is the most radical, but also the most reliable method in cases where other options are exhausted, and it is guaranteed to remove any software screen, including a fingerprint.
Unlocking through Fastboot mode
Fastboot mode is designed to provide low-level firmware for the device, but can also be used to reset passwords when you have the right rights or tools, a more complex method that requires a connection to a PC.
To go to Fastboot, turn off your phone and press the volume button along with the power button, and the screen will show an image of a hare repairing an android, signaling a successful entry.
To work in this mode on the computer must be installed drivers ADB/Fastboot. Connect your smartphone to your PC with a cable. Open the command line and enter a command to check the connection:
fastboot devicesIf the device appears in the list, you can execute a userdata partition cleaning command, although on newer models this can be blocked by the bootloader:
fastboot erase userdataWhat is an unlocked bootloader?
It is worth noting that on devices with a locked bootloader (Locked Bootloader), the fastboot erase command will not be executed without a special unlock token, in which case this method is useless without prior preparation.
Fastboot is justified if standard Recovery doesnβt start or is damaged.Itβs a tool for advanced users who understand the risks of firmware.
Engineering menu and debugging by USB
The Engineering Mode is hidden from the user, but it contains diagnostic tools, and sometimes it can bypass some limitations if the touchscreen is partially functional.
You can get there through dialer code if the screen responds to clicks in the dialing area. Try entering ##6484## or ##4636##. However, on global versions of MIUI, these codes are often blocked.
If you have had pre-debugging enabled USB (USB Debugging, it's easy. You can use it if you connect your phone to your PC. ADB-commands to delete key files:
adb shell rm /data/system/gesture.key
adb shell rm /data/system/password.keyThese commands delete files that store password and pattern lock hashes, and after rebooting, the system can accept any input or suggest that you install a new code.
| Method | Conditions required | Data security | Difficulty |
|---|---|---|---|
| Mi-account | Internet, account password | No (deletion) | Low. |
| Recovery | Physical access to buttons | No (deletion) | Medium |
| Fastboot | PC, drivers, unlocked BL | No (deletion) | Tall. |
| ADB Commands | USB debugging enabled | Yeah (saving) | Tall. |
You can only use ADB if you have previously activated this feature in the Developer Menu. Without this step, your computer will not have sufficient permissions to modify system files.
Problems with the fingerprint sensor
Often the problem is not the forgotten password, but the physical malfunction of the scanner. If the fingerprint scanner has stopped responding, the phone may require input. PIN-code every 72 hours or after rebooting.
The reasons can be different: contamination of the surface, a protective film pasted on the scanner, or a software driver failure, in some cases, a simple reboot of the device helps.
If the scanner is physically damaged (crack, moisture), you can only bypass it by knowing an alternative method of entry. Android always requires a backup authorization method.
β οΈ Note: If the scanner is damaged, do not try to disassemble it yourself if you do not have experience, as the plume module is very easy to damage.

Alternative entrance through PIN-code or pattern lock is the only way to get into the system when a biometric sensor breaks.
In the security settings, you can remove old prints and add new ones if you still have access to the menu, sometimes calibrating the sensor through the engineering menu helps restore sensitivity.
Third-party utilities and service centers
There are many PC programs that can unblock Xiaomi in one click, examples being the Mi Unlock Tool (the official utility) or various third-party flashers.
The official Mi Unlock utility requires a wait of 7 to 30 days after an account is linked to a device, a security measure to prevent data theft. Third-party programs often contain viruses or require payment for a questionable result.
If none of the software methods worked, you can go to an authorized service center, and if you have a check and a box, you can reflash the device officially.
Using unofficial firmware or security patches can cause banking applications (Google Pay, Mir Pay) to fail.SafetyNet will mark the device as compromised.
