Flagship owners often face the desire to unlock the full potential of their gadget, and unlocking the bootloader is the first and most important step in the process. The Xiaomi Mi 10 smartphone, based on the powerful Snapdragon 865 processor, has a huge hidden resource that the standard MIUI shell does not allow you to use to the fullest. Obtaining administrator rights opens the door to install customized recaps, deep customization of the interface and removal of system debris that cannot be eliminated by standard methods.
However, this process requires care and a clear follow the algorithm, as any error in the interaction stage with Bootloader can lead to the inoperability of the device. USB-cable, as well as a computer running Windows, as the main utilities of Xiaomi are optimized for this platform. Before any manipulations, we strongly advise you to create a full backup of all important data, since the unlock procedure will inevitably lead to the complete removal of information from the internal drive.
In this article, we will take a closer look at each step, from applying for MIUI to the final lock reset via Fastboot. You will learn about the nuances of working with the Mi Unlock Tool and the possible problems that users face when trying to modify the system partition. Understanding the physical processes that occur with the memory of the phone during flashing will help you act more confidently and avoid panic in case of unexpected situations.
Preparation of the device and Mi Account
The foundation of successful unlocking is the right linking of the device to your account. Xiaomi's security system tightly links IMEI-A smartphone code with a specific Mi Account, and trying to unlock a device registered to another user is doomed to failure. You need to log into your smartphone settings, go to the About Phone section and click on the version several times. MIUI, To activate the developer menu, you'll then find the "Mi Unlock Status" option in the advanced settings and activate it by confirming your account login.
An important aspect is the binding SIM-The loader checks for active SIM-The card is in the slot, and it has to be registered to the same number as the Mi Account, or it has to be just on the device during the binding process. Without this step, the company's servers will not issue permission to unlock, and the utility on the computer will give an anchor error. Some users recommend a pause of 168 hours (7 days) after the binding, although often the process takes less time, but it is not necessary to hurry here.
⚠️ Warning: Do not attempt to log out of your Mi Account or reset your phone immediately after you have tied it.This will void the waiting timer and require a re-assignment procedure, which can delay the process indefinitely.
It's also worth making sure that the device has USB debugging enabled. This option is on the developer menu and allows the computer to exchange commands with the phone at a low level. Without activated USB debugging, the computer will not be able to correctly identify the device in ADB mode, which will make it impossible to switch to Fastboot mode by software. Check the battery: it must be at least 60% so that a sudden power out does not interrupt the critical data recording process.
Installation of drivers and software on PC
The computer part of the training is often the most difficult for beginners, especially when working with the Windows 10 or 11 operating system. To work properly, you will need the ADB and Fastboot drivers, which are often included in the SDK Platform Tools from Google. However, for Xiaomi devices, it is critical to install specific drivers that come with the Mi Unlock utility. Without them, the Device Manager will see the phone as an unknown device or charger, ignoring the commands to control the bootloader.
The Mi Unlock Tool itself must be downloaded exclusively from the official website miui.com/unlock. Using third-party versions or modified builds can lead to leakage of your credentials or incorrect operation of unlock scripts. After installing the program, log in using the same Mi Account credentials used on the phone. The system will automatically check the status of the binding and tell you how much time is left before unlocking.
☑️ Preparation of PC and software
In the process of installing drivers, you may need to disable the digital signature check for drivers in Windows, which is standard for low-level drivers that interact directly with the hardware. If you are using an antivirus with aggressive protection, it should also be temporarily suspended, as it can block the Fastboot protocol from working, considering it suspicious activity. USB-The port to which the phone is connected is operating USB 2.0 or 3.0 and is not located on the front panel of the system unit, where voltage drawdowns are possible.
Getting permission and waiting for a timer
Xiaomi’s policy is to have a waiting period for all users who want to unlock their device, to give the owner time to understand their actions and make sure that this procedure is necessary, as it reduces the level of data security. Once you apply through the Mi Unlock Status app on your phone, you will receive a notification that permission will be given after a certain number of hours or days, usually from 7 to 15 days, but in rare cases it can be reduced or increased.
During this waiting period, you can safely use your smartphone as normal. However, do not try to bypass the timer by flashing or changing the region - this will not work, since the information about the unlock time is stored on the company's servers and is tied to the UID of your account. If you try to start unlocking ahead of time, Mi Unlock will show the exact number of hours left until the wait is completed.
There is a myth that changing the region of your phone to India or Singapore speeds up the process. In practice, this is not guaranteed and can lead to unstable work of some system applications that are tailored to a specific geographic region. It is best to be patient and wait for official permission to avoid potential software conflicts.
Unlocking process through Fastboot mode
When the timer is up and you get the alert, you can move to the practical part. The first thing you need to do is to put the Xiaomi Mi 10 smartphone into Fastboot mode. To do this, turn the device off completely, and then press the volume and power down buttons at the same time. Hold them until the image of a hare repairing an android appears on the screen, or the inscription FASTBOOT. This is a low-level mode that allows you to interact with the memory partitions of the phone directly, bypassing the operating system.
Connect your phone to your computer using USB-In the Mi Unlock Tool, press the Unlock button. The program will start checking the status of the device and checking with the server. If all data match and the timer has expired, the unlock process will begin. At that point, the phone will restart, and a warning may appear on the screen that the device is unlocked, a process that takes anywhere from a few seconds to a couple of minutes, depending on the speed of the connection to the server and the version. MIUI.
fastboot oem unlock
fastboot flashing unlockSometimes manually entering commands through the console may be required if the utility's GUI freezes, but 99 percent of the time, the automatic mode is stable. Once successfully unlocked, the phone will automatically perform a full Wipe Data reset, which is a mandatory security measure. This prevents attackers from accessing your data in the event of a device being stolen and attempted to flash it. Once reboot, you'll see a clean system, as after you purchase.
⚠️ Warning: Once the bootloader is unlocked, Play Protect may mark some banking applications as potentially dangerous, a normal reaction to the system's changed status, and additional manipulations will be required to operate banking applications (hiding root rights).
Installation of TWRP and obtaining Root rights
An unlocked bootloader is only halfway. To gain full control of the system, you need to install custom recoveries, such as TWRP (Team Win Recovery Project). This is a specialized recovery environment that allows you to make full backups of the system, install custom firmware and patch system files. For the Xiaomi Mi 10, it is important to download the version of the TWRP that is intended for the device code name (for example, umi), since incompatible recoveries may not see memory parts or work with the touchscreen.
The installation process is done via a computer in Fastboot mode. You'll need a.img image file and a command for flashes. Once you install TWRP, you can boot into it by holding down the power button and increasing the volume. Inside the receptacle, the first thing you need to do is format the Data partition to unencrypt, otherwise you can't write files to the phone. After that, you can install the Magisk archive, which grants superuser rights (Root).
| Component | Appointment | Risks. |
|---|---|---|
| Bootloader | Checks the digital signature of the OS before booting | Locking the device in case of error |
| TWRP | Environment for installation of software and backups | Possible loss of data during formatting |
| Magisk | Managing Root Rights and Modules | Inoperability of banking applications |
| Fastboot | Low-level firmware protocol | Risk of "bricking" when interrupted |
Once installed, Magisk will have superuser rights, allowing you to uninstall system applications, modify fonts, make full clones of the system, and use powerful automation tools. However, it is worth remembering that having Root rights makes some applications that require high security vulnerable. Use root hiding features in Magisk (formerly MagiskHide) settings to bypass security checks in banking software.

Possible mistakes and ways to solve them
Despite the smoothness of the process, Xiaomi Mi 10 users can encounter various errors. One of the most common is the error "Couldn't verify device" or "This device could not be verified." Most often this is due to the fact that the account on the phone and the program on the PC differ, or not enough time has passed since the binding. Check whether the email or phone number specified in the phone settings and in the Mi Unlock application.
Another common problem is that the MI logo freezes after unlocking or firmware, which can mean that the system partition has been damaged or incompatible firmware has been used, and only if you return to the stock version via Fastboot mode using the official firmware file, you may also experience an “anti-rollback” error that occurs when you try to roll back to an older version of Android than the one you installed earlier.
💡
Use the original. USB-Cheap cables often can’t withstand current when writing large amounts of data in Fastboot mode, leading to connection breakage and firmware errors.
If Mi Unlock does not see the phone, although the drivers are installed, try changing the device. USB-port or cable, sometimes it helps to restart the service ADB It is also worth checking whether the Windows firewall blocks the connection of the utility to the Internet, since communication with the authorization server is critical in the first stage.
⚠️ Warning: Never interrupt the firmware or unlock process by pulling the cable out.This can damage the boot sector (PBL), The phone will turn into a brick, the recovery of which is possible only through paid service tools like Mi Auth or Edl-mode.
