Modern smartphones Xiaomiworking on the base Android 10 and shell MIUIhave a high level of protection, which in certain situations can become obstacle for the owner. Users are often faced with the need to remove the screen lock, bypass the link to a Google account after resetting the settings, or gain full access to the system to install custom software.
The unlocking procedure varies depending on the type of lock: it can be standard FRP Lock (Factory Reset Protection), bootloader lock Bootloader or forgotten graphic key. It is important to understand that the actions described in the article require technical literacy and may lead to loss of warranty or data.
In this material we will analyze in detail the legal and technical methods of restoring access to the device. We will look at official ways to obtain superuser rights and ways to bypass system restrictions that arise when purchasing used equipment or after unsuccessful experiments with firmware.
⚠️ Attention: Any manipulations with the system partition and bootloader are performed at your own peril and risk. The author of the article is not responsible for turning a smartphone into a “brick”. Before starting work, be sure to create a backup copy of important data if the device is still accessible.
Differences in types of blocking in the Xiaomi ecosystem
Before taking active steps, you need to clearly identify the problem. Users often confuse different levels of protection, which leads to using the wrong tools and wasting time. Devices on Android 10 implement several layers of defense.
The first level is Screen Lockwhich is a pattern key, PIN code or fingerprint. You can reset it through Recovery mode, but this will entail activating Google protection. The second level is FRP, which requires entering the account data synchronized with the phone before the reset.
The third and deepest level is Locked Bootloader. By default, all smartphones Xiaomi come with a locked bootloader. This prevents the installation of unofficial firmware, obtaining root access and deep modification of the system. Unlocking this component is a separate procedure that requires permission from the manufacturer.
- 🔒 Screen lock: protects against physical access of unauthorized persons to the interface.
- 🔐 FRP (Google Lock): theft protection, activated after a hard reset (Hard Reset).
- ⛓️ Bootloader Lock: software lock, prohibiting modification of system partitions and loading signed images.
The official method of unlocking the bootloader via Mi Unlock
The only legal way to remove the restriction Bootloader on smartphones Xiaomi is to use a proprietary utility Mi Unlock Tool. This process requires linking the device to a Mi account and waiting for a certain time set by the company's security policy.
First, you need to go to the developer settings. Go to the menu Settings → About phone and quickly click on the item MIUI version seven times until the notification “You have become a developer” appears. After that, in the advanced settings, find the item For developers.
In the developer menu, activate the switch Factory unlocking (OEM Unlocking) and execute account linking. The system will warn you that this action may lead to data deletion. Confirm the action by entering the password from your Mi account. Only after this procedure will the device be ready to interact with the PC.
☑️ Preparing to unlock the bootloader
Next you need to download the official utility Mi Unlock from the developer’s website and install it on your computer OS Windows. Launch the app and log in to your Mi account. Switch your smartphone to Fastbootmode by simultaneously pressing the power and volume down buttons while the device is turned off.
Connect your phone to the computer via the original USB cable. The utility must detect the device. Click the button Unlock. If less than 168 hours (7 days) have passed since the account was linked, the system will generate an error with a wait timer. In this case, you will have to wait without unlinking your account or resetting the settings.
⚠️ Attention: The Mi Unlock application interface and waiting times may vary depending on the firmware version and region. Always check the latest requirements in the official MIUI community or on the support site before starting the procedure.
Bypassing Google FRP protection on Android 10
The situation when, after resetting the settings, the phone requires you to enter a password for your Google account, which you do not remember, is one of the most common. Protection FRP on Android 10 has become significantly stricter compared to previous versions, closing many vulnerabilities of the browser and settings menu.
One of the working methods for some versions MIUI is based on the use of TalkBack and a voice assistant. Activating this feature allows you to access certain menus that are usually hidden on the Welcome screen. However, this method requires precision and care when performing gestures.
There is also a method using a special APK file, which is installed through the emergency call menu or through connecting a keyboard. A file manager or browser allows you to download an account reset utility, such as FRP Bypass or Google Account Manager. After installation and launch, the application allows you to add a new account and unlock the device.
Technical details of FRP
The system stores the hash of the last synchronized account in the protected persist section. During the first setup after wipe data, the entered data is compared with this hash. The workaround involves replacing system components or temporarily disabling the scanning service.
It is important to note that the effectiveness of the methods depends on the specific version of the security patch Android. If your device has the latest monthly update, older exploits may not work. In this case, the only solution is to flash the device through EDL (Emergency Download Mode), which requires an authorized service center account or paid tools.
- 📱 TalkBack method: using gestures to call up the settings menu and turn on the browser.
- 💻 Method via PC: sending commands ADB to remove authentication files (requires USB debugging).
- 🔧 Service mode: entering the engineering menu via code

Using Recovery and Fastboot mode to reset
Mode Recovery is a standard recovery tool built into every smartphone Xiaomi. It allows you to perform a complete data reset (Wipe Data), which is often necessary before selling the device or in case of serious software failures.
To enter this mode, turn off the smartphone and hold down the buttons Volume Up + Power. In the menu that appears, use the Volume buttons to navigate and the Power button to confirm your selection. The item Wipe Data initiates formatting of the user section.
However, as mentioned earlier, using Recovery to reset the screen lock activates FRP. If your goal is to simply clear your phone of data, this method is ideal. If you have forgotten your password and hope to bypass the protection in this way, then Android 10 this number will not work without additional manipulations with your Google account.
| Action | Keyboard shortcut | Result | Risk of data loss |
|---|---|---|---|
| Entering Fastboot | Volume Down + Power | BL flashing and unlocking mode | No (without wipe command) |
| Enter Recovery | Volume Up + Power | Reset and Update Menu | Yes (when selecting Wipe) |
| Reboot | Long pressing Power | Normal system start | No |
| Emergency mode (EDL) | Special. combination or test points | Deep firmware via MiFlash | High (complete cleaning) |
If the phone reboots cyclically (bootloop), entering Recovery mode may be difficult. Try connecting the cable to the PC at the moment of vibration when turning on, in order to “catch” the moment of loading.
Problems with drivers and connection to the PC
The success of any unlocking procedure is 90% dependent on the correct operation of the drivers on the computer. Often, users are faced with the fact that the utility Mi Unlock or console ADB simply does not see the connected device, despite a working cable.
To work with Xiaomi in Fastboot mode, specific drivers are required Qualcomm or Android Bootloader Interface. They can be installed manually through Windows Device Manager. If “Unknown Device” or “QHSUSB_BULK” is displayed in the list of devices, it means that the drivers are not installed or selected incorrectly.
It is recommended to use the original USB cable included in the package and connect it directly to the motherboard port on the rear panel of the system unit, avoiding the use of USB hubs and front ports of the case. Unstable power supply or poor contact can interrupt the unlocking process at the most critical moment.
To check the connection, open the command line on your PC and enter the command:
fastboot devicesIf you see the device serial number in response, it means the connection is established correctly. If the line is empty, the problem lies with the drivers, cable, or port. Try to reinstall the drivers by manually selecting them from the list and specifying the path to the folder with the unpacked files ADB/Fastboot.
⚠️ Attention: Never disconnect the cable during the unlocking or flashing process. Interrupting the writing of data to the bootloader section can lead to irreversible damage to the device, which can only be corrected in a service center using a programmer.
Frequent errors and ways to eliminate them
During the unlocking process, users often encounter error codes that can confuse them. Understanding their meaning helps you quickly find a solution and not panic. Most errors are related to network problems or software version mismatches.
Error 'Couldn't verify device' usually means that the Mi account is not linked to the device or not enough time has passed since the linking. This error also occurs if the “Factory unlock” option is not enabled in the developer settings. Check the Internet status on your PC and phone.
Message 'Unlock failed: Please try again later' may indicate server overload Xiaomi. In this case, you should wait a few hours or try to perform the procedure at a different time of day. Sometimes changing the version of the utility helps Mi Unlock to an older or newer one.
Most unlocking errors are resolved by checking the Internet connection, reconnecting the cable to another USB port and strictly observing the time interval of 168 hours after linking the account.
If the utility gives an error, related to account mismatch, make sure that you are logged into the same Mi account that was used to link the device in the settings. Changing an account in the Mi Unlock app without unlinking it from the phone will block the process.
