The process of flashing Xiaomi smartphone often becomes a necessity when the device starts to work unstable, the battery runs too fast or the regional version of the operating system does not support the right languages and services. Owners of gadgets often face a situation when automatic updates stop coming or the new version of MIUI contains critical errors that interfere with everyday use.
Modern tools allow you to perform this procedure even for a beginner, if you follow the algorithm of actions and prepare all the necessary files in advance. It is important to understand that there are several methods of downloading, each of which has its own characteristics and risks. Recovery Mode is suitable for simple updates, while Fastboot requires a deeper immersion in system processes, but gives full control over the device.
Before you take action, you need to be aware of your responsibility for your actions, because interference with code can lead to loss of warranty or data. Incorrectly selected firmware for a particular model can turn a smartphone into a brick. In this article, we will discuss in detail all the stages of preparation, selection of files and direct installation to minimize risks and get the desired result.
Selection of firmware type and preparation of tools
The first and most critical step is to determine the type of software you need to install. Global versions differ from China in having Google services pre-installed, support for multiple languages, and tailored communication frequencies. When choosing a file, it is also important to pay attention to the type of build: Stable contains proven fixes, and Beta includes new but sometimes unstable features.
To do this successfully, you'll need not only the system image file itself, but also specialized software on your computer, most commonly using the Mi Flash Tool for the Fastboot method or the built-in updater for Recovery. USB-cable, providing a stable current and data transmission, the process can be interrupted at the most inopportune moment, which is fraught with trouble.
⚠️ Note: Download firmware only from official sources or verified forums, as modified files may contain malicious code.
Make sure that your computer has all the necessary drivers for working with Xiaomi devices. Often the problems with recognizing your phone in boot mode arise precisely because of the lack of ADB or Fastboot drivers. Check for free disk space, as unpacked archives can take up a significant amount of space.
What is the difference between Recovery and Fastboot?
Preparing a smartphone for flashing
Before you start any manipulation of the system partition, you need to perform a number of mandatory steps to prepare the device itself. The first step is to create a full backup of all important data, since in most cases, especially using the Fastboot method, the internal memory will be completely cleared.
The battery charge shall be at least 60-70%, So that the device doesn't turn off while recording memory sectors. SIM-MicroSD card and memory card to avoid accidental data corruption on them or conflicts when working with the file system. USB-devices from the computer, leaving only the mouse, keyboard and smartphone cable.
☑️ Checklist of preparations
If you plan to use the unlocked bootloader method, make sure that your Mi Account has been linked to your device at least 7 days ago (168 hours), a mandatory Xiaomi security requirement that cannot be circumvented by standard methods.
Method 1: Update via Recovery (without PC)
This is the easiest and most secure way to do this, because it doesn't require a computer connection or an unlocked bootloader, and it's perfect for updating the MIUI version within a single region or switching between stable builds. First, download the firmware file with the.zip extension and put it at the root of the smartphone's internal memory.
Then go to the recovery menu. To do this, go to the settings, select About Phone, and click a few times on the MIUI version until the optional menu is activated. Then click on three dots in the corner of the screen and select Select firmware file. The system will check the integrity of the archive and suggest starting an update.
- 📱 Click on the version icon MIUI customized 7-10 once.
- 📂 Copy the.zip file into the root memory folder.
- 🔄 Select the file through the updater menu and click the update button.
- ⏳ Wait for the process to be completed and the automatic reboot.
It is important not to interrupt the process or use the phone until the operating system is fully loaded. If after a reboot the device requests an account password or lock code, this is a normal security check procedure, and in some cases a complete data reset may be required, which the system will warn you about in advance.
💡
If the phone doesn’t see the firmware file, rename it to “update.zip” and make sure it’s at the root, not in the Download folder.
Method 2: Installation via Fastboot (from PC)
Fastboot provides a deeper level of access and allows you to completely reinstall the operating system, fixing file system errors. It requires a Windows computer, installed Mi Flash Tool and unlocked bootloader. Downloaded firmware with the extension.tgz must be unpacked into a short-cut folder, preferably the root of the C disk, so that there is no Cyrillic on the way.
Put your smartphone into Fastboot mode, pressing the volume down button and the power button when the device is off. Connect the cable to your PC, then the Android Bootloader Interface should appear in the Device Manager. Launch the Mi Flash Tool, press the Refresh button and make sure that the program sees your device by its serial number.
| Parameter | Meaning/Description | Importance |
|---|---|---|
| Loading mode | Fastboot (android hare) | Critically. |
| Driver. | Qualcomm / Xiaomi USB Driver | Tall. |
| The path to files | No Cyrillic and no gaps. | Medium |
| Lockdown | Unlock Status: Unlocked | Critically. |
In Mi Flash Tool, select "Clean all" to delete all data and install a clean system, or "Clean all and lock" if you return the device to factory state with the bootloader closed. Press the "Flash" button and wait for the process to be completed, the indicator of which will be displayed in a green bar. Once successful, the phone will automatically restart.
💡
The use of the "Clean all and lock" option is possible only when installing global firmware on a global device, otherwise there will be a region check error.
Solving errors and problems
Users often encounter various bugs during the firmware process that can stop the process. One of the most common problems is the “Missmatching image and device” error that occurs when trying to install firmware from another model. Always check the device’s code name (for example, cepheus for Mi 9 or raphael for Redmi K20), which must match the folder name in the archive.
If the process is stuck at a certain percentage or gives a connection error, try replacing it. USB-cable or switch port on the back of the computer (USB 2.0 is often more stable than 3.0 for older devices. Reinstallation of drivers through Device Manager, where you need to manually update the driver for a device with a yellow exclamation mark, can also help.
⚠️ Warning: If your phone goes into an endless bootloop after firmware, try doing Wipe Data through Recovery or reflashing the device again with all data cleaned.
In the event of an anti-rollback error, the protection system prevents the installation of an older version of the software than the one installed earlier. You can not circumvent this limitation with standard methods, since this is a downgrade protection mechanism. You will have to look for a more recent version of the firmware or wait for the current build to come out.
