Install firmware on Xiaomi via MiFlash: the complete guide

Xiaomi’s mobile devices are renowned for their functionality, but even the most stable systems sometimes face critical bugs that require a complete reinstallation of the operating environment. Using the specialized MiFlash Tool allows you to restore the health of your smartphone, delete forgotten passwords or switch from the global version of the software to the Chinese one, and vice versa. This method is considered the most reliable way to reanimate the device, since it works at a low level, ignoring the state of the Android software.

The process of flashing through a PC requires careful preparation and understanding of all the risks associated with tampering with system files. Unlike an over-the-air update, the MiFlash method completely erases the UserData partition, so backup is a must before you start. USB-cable, charged smartphone battery and pre-downloaded archive-copy of firmware in Fastboot format.

Before you start taking action, make sure you clearly understand your device model and the region your operating system is designed for. Incorrectly selected software can cause communication modules to fail or your device to fail completely, so carefulness in selecting a firmware file is critical. Next, we will take a detailed look at each step necessary to successfully complete the procedure.

Preparation of the working environment and choice of firmware

The first step is to find and download the correct version of the software that is compatible with your device.The official source for obtaining files is miui.com or specialized forums where original images are posted. It is important to distinguish between the types of firmware: Recovery (update without loss of data, but not for MiFlash) and Fastboot (complete cleaning, designed for the tool of the sewer).

Fastboot files usually have a.tgz extension and weigh between 3 and 5 gigabytes, depending on the model and version of Android. Once downloaded, the archive must be unpacked into the root of the C disk so that the path to the folder does not contain Cyrillic characters or spaces, as this often causes errors when reading paths by Windows utilities.

For the correct operation of the computer with the phone, you need to install the current ADB and Fastboot drivers. Without them, the PC operating system simply will not see the smartphone in the right mode, and the firmware startup button in the program will be inactive. Often the drivers are bundled with the MiFlash installer, but it is more reliable to download them separately from the official developer website.

Checking the integrity of a downloaded file is an important step that many people ignore and then wonder at the errors in writing. If the archive is damaged during download, the process can be interrupted in the middle, which will lead to unpleasant consequences. Use checksums if they are provided by the developer, or simply double-check the file on another device.

Unlocking the loader: a mandatory stage

Xiaomi has implemented a security mechanism that prohibits third-party flashing without prior permission, called Bootloader, which is the default lock to protect user data from intruders. To work with the MiFlash Tool, the bootloader must be unlocked, otherwise the program will give an authorization error.

The unlocking procedure requires a device-based Mi Account and a waiting period of 7 to 168 hours, depending on the company's current policies: You need to install the Mi Unlock app on your computer, log in to your account and follow the instructions on the screen. SIM-card with active tariff - inserted into the slot.

⚠️ Warning: The process of unlocking the bootloader automatically resets all data on the smartphone. Pre-save photos, contacts and documents to the cloud or computer.

After successfully unlocking the device, an image of a hare repairing an android will appear on the boot screen and the inscription FASTBOOT. This is a visual indicator that the restrictions are removed and the device is ready to accept commands from the computer. Re-locking the bootloader after installing custom or regional firmware can lead to the “bricking” of the phone.

Some users try to bypass waiting times or use paid unlock services.This is a risky path that can lead to the blocking of the Mi Account forever.

Installation of drivers and start MiFlash Tool

MiFlash requires Windows 7, 10 or 11 to work. On macOS or Linux, this tool won’t run without emulators, which adds added complexity and potential bugs. Download the latest version of the program from a trusted source, as older versions may not support new smartphone models on Snapdragon or MediaTek processors.

Installation of drivers often occurs automatically when the application itself is installed, but the Device Manager may have unidentified devices left, in which case you need to manually update the driver by specifying the path to the driver folder inside the installed program directory. Make sure that the Android Bootloader Interface appears in the list of devices after connecting the phone in Fastboot mode.

The program should be run on behalf of the administrator to avoid problems with access rights to system ports. The MiFlash interface looks ascetic, but contains all the necessary buttons to manage the process. The main window displays the list of connected devices and the path to the firmware files.

• 🔌 Connect your smartphone in Fastboot mode (click the volume down button and connect the cable).
• 💻 Launch the MiFlash Tool and press the Refresh button to search for your device.
• 📂 Click Select and point the way to the unpacked folder with firmware.
• ✅ Make sure that a device with a serial number appears in the list.

If the device is determined, but it is lit in yellow or red, this may indicate a driver problem or incompatibility of the bootloader version. In this case, it is worth checking the Windows Device Manager for exclamation points. Sometimes it helps to reinstall Qualcomm or MediaTek drivers depending on the platform of your gadget.

Step-by-step instructions for firmware through Fastboot

Now, the most important thing is the actual process of writing data, and in the MiFlash window, you'll see three options for doing the operation at the bottom of the interface, and the right mode depends on your goals: whether you want to save the data or if you want to clean it completely.

The first option is clean all, deletes all user data completely, and installs a clean system, which is a recommended choice when recovering from bugs or changing the firmware region, and the second option is save user data, which tries to save files, but can lead to unstable work if the software versions are very different.

The third option, clean all and lock, not only cleans the data, but also re-blocks the bootloader, which you can only use with the original firmware in the same region that was installed initially, and if you try to lock the bootloader on the Chinese firmware of a global device or vice versa, the phone turns into a brick with a verification error.

After selecting the mode, press the Flash button and watch progress in the column "Progress." The process takes 200 to 500 seconds, depending on the speed. USB-At this time, you should not disconnect the cable or turn off the computer, since interrupting the recording of the system partition is fatal.

When the procedure is completed, the "Result" column will show the success message, and the phone will automatically restart. The first boot after the firmware can last up to 10-15 minutes, as the system optimizes applications and creates new configuration files. Be patient and do not try to interrupt this process, even if the screen remains black for a long time.

Solving common mistakes

Even with strict adherence to the instructions, technical failures can occur that interrupt the process. One of the most common errors is the message Miss matching image and device. This means that you are trying to install firmware that is not designed to encode your device (for example, the firmware for the Redmi Note 10 Pro on the Redmi Note 10).

Flash storage error or timeout error often indicates problems with the physical connection. Use a short, high-quality cable connected directly to the computer motherboard (back of the system unit), bypassing the system. USB-Hubs and front panels of the case. Long cables may not provide enough voltage for stable data transmission.

⚠️ Note: If the program produces an error "Anti-rollback check failed", then you are trying to roll back to an older version of the software, which is prohibited by the security mechanism.

If the process is stuck at a certain percentage (e.g. 53% or 98%), don't panic and pull the cable out immediately. Wait 5-10 minutes, sometimes writing large partitions takes longer. If the status remains unchanged for more than 15 minutes, then you can try rebooting the phone to Fastboot mode again and repeat the procedure.

💡

Use it. USB-Port 2.0 (black connector) instead of 3.0 (blue connector) Qualcomm drivers often work more stable with the old standard. USB, Reduces the likelihood of connection breaks during firmware.
