How to unlock Xiaomi bootloader: the complete guide

Owning a Xiaomi or Redmi device is often the starting point for a deep dive into the world of Android modifications. Many users are faced with the desire to gain full control of the operating system, install custom recavators or specific modules. However, the path to freedom is a locked bootloader, which is the main obstacle to making changes to the system partition.

The process of removing restrictions is not trivial and requires careful preparation, the presence of a Mi Account account and special software. Unlike many other manufacturers, Xiaomi has implemented a strict security policy that requires waiting for a certain time, this is done to protect user data, but for enthusiasts it becomes a barrier that needs to be overcome.

In this article, we will take a look at all the steps of the procedure, from application to final reset, learn about the pitfalls that can occur when using the Mi Unlock Tool utility and how to avoid them. Understanding each step is critical, as an error can lead to malfunctioning of the device.

Understanding Security Architecture and Mi Account

Before you start taking action, you need to realize that unlocking a bootloader is not just a switch in the settings; it is a process that is closely related to the developer account and the company's servers. Your Mi Account should be tied to the device, and the server should "allow" the unlock for this particular gadget.

There's a common misconception that you can use any account, and in fact, the link is made when you apply through a special application. SIM-A card or account is waiting, the timer may reset.

⚠️ Warning: Once successfully unlocked, all data on the device will be permanently deleted. The system will compulsorily execute Wipe Data for security reasons, so backing up is a must.

Also, it is worth considering that some security features, such as Find My Device or anti-theft protection, may work differently on an unlocked device, and applications that require a high degree of system integrity, such as banking programs without additional manipulation, will cease to work.

Preparation of the device and obtaining developer rights

The first practical step is to enable hidden features in the operating system, so you need to activate the developer mode to access the USB debugging, and without that, the computer won't be able to interact properly with the phone at a low level.

To do this, go to the Settings → About Phone menu and find the MIUI Version (or OS Version) string. You need to quickly click on this line 7-10 times in a row. Once the notification “You became a developer” appears, you can move to the next step.

Now open the expanded Settings menu → Additional settings → Developer, and you're interested in two key items: USB Debugging and Factory Unlocking: One allows you to transmit commands, and the other connects the device to the verification server.

In the factory unlock menu, you'll need to link your account. Click "Add Account and Device" and the system will check if you have an account. SIM-If it goes well, you'll see the status of "Tieed." That's when the waiting time starts.

Application process and waiting

Once you have an account on your smartphone, you need to wait for permission from Xiaomi servers>. This usually takes from 168 hours (7 days) to 30 days, depending on the region and the current server load.

During this period, it is not recommended to log out of your Mi Account account on your device, and avoid resetting to factory settings, as this will break the link between the unique device ID and your profile in the database.

There's a myth that you can reduce your waiting time by going to the unlock menu all the time, and in practice, it doesn't affect the server's decision, and the only way to speed up the process is to use paid intermediaries with direct keys, but that carries risks to your data security, and you'd better be patient and wait for official permission.

When the deadline expires, the application on the phone (Mi Unlock Status) will be able to unlock the device, or you will receive a new device. SMS-Notification. Only then can you go to work with a computer.

Installation of drivers and setting up Mi Unlock Tool

To interact with your smartphone in bootloader mode, you will need a PC running Windows. Linux and macOS are not officially supported by the Mi Unlock Tool utility, although there are workarounds through virtual machines that we will not consider.

Download the latest version of the program from the official website. Older versions may not support new models or verification protocols. Once installed, launch the program and log in to the same Mi Account that was linked to the phone.

The critical thing is to install the right drivers. miflash_setup.exe or a separate driver folder. Make sure that in the Device Manager when connecting the phone in Fastboot mode (clamping the volume down and USB) The device is defined as Android Bootloader Interface.

If the device is correctly identified, click the Unlock button in the program. The utility will perform the final check of the account status on the server. If the waiting time is out, the process will start automatically.

Unblocking and possible errors

The process takes anywhere from a few seconds to a couple of minutes, and the phone screen will change, and the Mi Bunny logo will appear, saying, "Unlocking..." At this point, you should absolutely not turn off the USB cable or interrupt the program.

⚠️ Warning: If the process is 99 percent frozen for more than 10 minutes, don't panic. Often this means that partitions are being finalized. Forced reboot can lead to a brick of the device.

However, users often experience an error such as “Couldn’t verify device” or “Current account is different.” The first error is often due to unstable Internet or server locking by the provider; the second one means that you logged in to the program on a PC from a different account than on your phone.

Another common problem is the message that Too many attempts is a defense mechanism that blocks the ability to unlock for 168 hours if you've tried the procedure too often.

First start and set up system

Once the procedure is completed, the phone will automatically restart, and you will see a warning that the bootloader is unlocked and the system will ask you to confirm the language and connect to Wi-Fi. This is a standard Factory Reset process.

The first run can take longer than usual, as the system reassembles the cache and optimizes applications. 15-20 It's normal behavior after cleaning the sections completely.

Now you can install custom recavers, such as TWRP, or get Root rights through Magisk. However, remember that from now on, the warranty on the software part of the device is removed, and some applications (banks, Google Pay without patches) may refuse to work.

💡

Once unlocked, install root rights manager or custom Recovery immediately if you plan to use them. Standard firmware once unlocked is vulnerable to accidental flashing by stock recapvers when upgraded through the air.

To check the status, you can use the command in Fastboot: fastboot oem device-info. In response, you should receive the line (bootloader) Device unlocked: true. This confirms that the restrictions are finally removed.
