How to Flash Xiaomi Phone Through Computer: Full Guide

Changing the operating system or updating software on Xiaomi smartphones often becomes a necessity when the standard operating system is not used. OTA-The update stops coming or the device starts to work unstable. The firmware through the computer gives the user full control over the process, allowing not only to update the version of Android, but also to change the region (for example, from China to the Global version), as well as restore the “brick” after unsuccessful experiments. Unlike an over-the-air update, the PC method requires careful preparation, but provides a more reliable result, as it eliminates interruptions due to unstable Wi-Fi.

In this article, we will discuss in detail how to reflash a Xiaomi Android phone through a computer at home using the official Mi Flash Tool. You will learn about the differences between the types of firmware, the need to unlock the bootloader and how to solve typical errors. Attention: all actions you perform at your own risk, although with strict adherence to the instructions, the probability of success is almost 100%.

Preparation of equipment and choice of firmware

The first step is to find the right system image file. To run through your computer, you need a file with the.tgz extension, which contains the so-called Fastboot ROM. It is important not to confuse it with Recovery ROM (extension.zip), which is designed to be installed through the Recovery menu of the phone itself. You can find current versions of the software on the official website miui.com or trusted resources like xiaomirom.com.

When choosing a file, look for the model code of your device, which should match what is indicated on the sticker under the back cover or in the box. Mismatching region or model can lead to communication modules failure or complete system failure.

• 📱 Make sure the battery is at least 60% in order to avoid a sudden shutdown.
• 💻 Use the original. USB-cable or quality analogue with data transmission support.
• 🔌 Connect the device directly to ports on the PC motherboard, avoiding USB-hub.

⚠️ Note: Using firmware from another device model (for example, the firmware from the Redmi Note 10 on the Redmi Note 10 Pro) is guaranteed to turn the phone into a “brick” with the impossibility of simple recovery.

Once the archive is downloaded, it needs to be unpacked, the path to the folder should be short and free of Cyrillic characters or spaces so that the firmware utility can read the files correctly. The best placement is the root of the C: disk, or the working folder on the D disk: with a name like Xiaomi_ROM.

Required drivers and utilities

For successful communication between the computer and the smartphone in bootloader mode, special drivers are needed. Standard Windows 10 or 11 often automatically installs the basic ADB drivers, but Fastboot and EDL mode often require specific components. The main tool for working with Fastboot ROM is the Mi Flash Tool, which should be downloaded from the official developer resource.

Installing drivers can be the most difficult step for beginners. If the Device Manager does not see the phone in Fastboot mode, you may need to manually install Qualcomm or MediaTek drivers, or use the Universal ADB Driver package. In some cases, the system may block the driver installation due to the lack of a digital signature, which will require a temporary disabling of the verification of driver signatures in Windows.

Once you install the Mi Flash Tool, run the program on behalf of the administrator, which is critical because without increased access rights, the utility will not be able to initiate the process of writing data to the device's memory. The program interface is quite simple, but it contains several important buttons, which we will talk about in the section with the instructions.

Unlocking the Bootloader bootloader

Most of Xiaomi’s global and Chinese firmware is protected from unauthorized change. Unlock Bootloader is a mandatory procedure for changing the region (for example, from CN to Global) or installing custom recavators. Without the unlocked bootloader, the Mi Flash Tool will give an error when trying to reflash the device, even if the files are selected correctly.

The unlocking process requires an application via the Mi Unlock app on the smartphone itself and a wait of 7 to 168 hours, a company-wide security mechanism designed to make it harder to steal devices, so once you get permission in the app, you need to log into the same Mi Account on your computer and press the unlock button, before you put the phone into Fastboot mode (pressing the power and volume buttons down).

It is worth noting that unlocking the bootloader leads to a complete reset on the device. Once unlocked, the phone will be forcibly cleared, so save all important contacts and photos in advance. Also, some banking applications may stop working or require additional security settings (Magisk, Root hiding), as they consider the device with an open bootloader less secure.

Step-by-step instructions for firmware through Mi Flash

Now, to the process itself. Make sure the drivers are installed, the firmware is unpacked, and the phone is charged. Run the Mi Flash Tool on your computer. Press the Refresh button to make sure the program is working correctly (the list of devices should be empty, since the phone is not yet connected in the right mode).

Take the smartphone off and press the Volume Down and Power buttons simultaneously. Hold them until the Fastboot logo (a picture of a rabbit in a hat fixing an android) or the words "FASTBOOT" appear on the screen. Connect the phone with a cable to your computer. A new device should appear in the Windows Device Manager under "Port Devices" or "Android Device."

In the Mi Flash Tool, press the Select button and specify the path to the folder with the unpacked firmware. The path should end with the folder where the image file and the script are located. flash_all.bat. After selecting the path again press Refresh – the list should appear serial number of your device.

• 🔹 Select firmware mode at the bottom of the window: Clean All (full cleaning) is recommended for stable operation.
• 🔹 Save User Data will try to save files, but can cause errors when changing versions of Android.
• 🔹 Clean All mode + Lock will lock the bootloader back, which is useful after installing global firmware.

⚠️ Note: When selecting the "Clean All" option + Lock make sure you flash the device to the same region it was originally designed for, or that you change the region back to the original. Locking the bootloader with someone else's firmware (e.g. Global on a Chinese device) will lead to eternal boot (Bootloop).

Press the Flash button to start the process. The progress bar will show the status of execution. At this point, it is strictly forbidden to turn off the cable or interrupt the power of the computer. The process can take from 200 to 600 seconds. Once completed, the phone will automatically restart. The first boot can last up to 10-15 minutes.

Solving Typical Errors and Problems

In the process of flashing, users often encounter errors. One of the most common is Missmatching image and device. It means that the selected firmware file does not match the device model. Check the model code again. Another common problem is Flash All Except Data And Storage, which occurs when the bootloader is locked and you try to change region.

If the utility is making an error, can not find flash_all.bat Or a similar path-related folder, check the folder name. It should not contain Russian letters or special characters. Move the firmware folder to the root of the disk, for example, in the root of the disk. C:\rom\.

If your computer stops seeing your phone during the process, try replacing it. USB-cable or connect the device to another port, sometimes helping reinstall drivers through the Manager of devices with manual selection from the list (Qualcomm) HS-USB QDLoader 9008 for mode EDL).

💡

If the phone is in EDL mode (only the indicators or black screen are on) and the Mi Flash Tool says "Firehose configure fail," try changing the USB port or using another cable.

Comparison of software update methods

Understanding the differences between the ways you install software will help you choose the best option for your situation. Below is a table comparing the main methods.

As you can see from the table, the computer method is the most powerful tool in the user's arsenal, and it allows you not just to update, but to completely reassemble the file system of the device, eliminating accumulated software debris and errors.
