How to Update Xiaomi: The Complete Guide to Installing MIUI

Xiaomi’s modern smartphone is a complex device that requires regular software maintenance. System upgrades are needed not only to gain new features, but also to close security vulnerabilities that can be exploited by malware. Many users ignore notifications, which can lead to unstable operation of the gadget in the long run.

Updating MIUI or a new HyperOS can be intimidating for a beginner, especially if it’s manually installed. However, following proven algorithms will help you keep your device up to date. In this article, we’ll look at all the ways you can install it, from standard OTAs to advanced methods through Recovery.

Preparation of the device before the procedure

Before you start the installation process, it is critical to complete a number of preparatory steps. Data backup is the first thing to take care of, as you can lose contacts, photos and documents if you fail. Use cloud services or the built-in Mi Cloud app to create a full copy of the system.

Make sure the battery is at least 60 percent, the firmware process can take anywhere from 10 minutes to an hour, and a sudden power outage can turn the phone into a brick. Also check for free storage: 3 to 5 GB of free space can be required to unpack the archive and temporary files.

⚠️ Note: If you are using a modified version of the root-righted system, a standard update may remove superuser rights or result in a cyclical reboot.

A stable Internet connection is another key factor. It is best to use a Wi-Fi network at high speed so that the file loading is not interrupted in the middle. 4G/5G mobile Internet is also acceptable, but keep an eye on traffic, since firmware files weigh a lot.

Automatic update via settings (OTA)

The easiest and safest way to get a new version of software is to use the built-in OTA (Over-The-Air) mechanism, which independently checks the servers for new versions and suggests installing them, a standard method that ensures that all components are compatible.

To start the check, go to the Settings menu, then select About Phone and click on the MIUI version logo. If the update is available, a download button will appear. After downloading the archive, the phone will prompt you to restart for installation.

Sometimes it happens that the notification comes later than other users. This is normal, because the update spreads in waves. You can speed up the process by clicking on the three dots in the upper right corner and selecting Check for Updates.

• 📲 Click on the logo of the system version in the menu "About the phone".
• 📲 Wait for the server to be checked and the package loaded.
• 📲 Confirm the installation and wait for the restart.

It is important to understand that OTA-Updates only come to global and stable firmware versions, and if you're using a Chinese version or beta build, this method may not work or suggest a switch to a different branch of software development.

💡

If the update button is inactive, try changing the region in the settings (for example, India or Singapore), checking for updates, and then returning your region.

Manual installation via Recovery (Method 3 points)

If the automatic method doesn’t work or you want to update forcibly, use the manual method through the built-in Recovery. You will need to download the current firmware archive from the official website or a trusted source. The file should have the.zip extension and weigh about 3-4 GB.

Copy the downloaded file into the root of the device's internal memory without putting it in folders. Then open the System Update app, click on the version logo and select Select firmware file. The system will check the integrity of the archive and suggest that you start installing.

This method allows you to update even when the servers have not yet updated specifically to your region, the main thing is to choose firmware strictly for your model, otherwise the device may stop booting.

Using Fastboot and Computer for Firmware

For advanced users or when the phone is not booting, Fastboot mode is used, USB-Mi Flash Tool cables and utilities, which allows you to completely re-mark memory partitions and install a clean system.

Put your smartphone into Fastboot mode by slamming the volume button when power is off and connecting the cable to your PC. In Windows Device Manager, your phone should be defined as Android Bootloader Interface. Run the sewer program, select the unpacked folder with ROM, and press Flash.

fastboot reboot

This is often used to move from the Chinese version to the global (Global) version, but it requires an unlocked bootloader. On new models, unlocking can be paid or require a wait of 168 hours.

⚠️ Note: Using Fastboot with the Clean All option will completely delete all data from the device, including photos, contacts and apps.

The Fastboot firmware process takes longer, but ensures that no software bugs are present, as all partitions are overwritten completely, and this is the best way to treat software bugs.

Transition between versions: China to Global and back

Many users buy Chinese versions of smartphones because of their price, but want to use global firmware with Google services and Russian, the process of changing the regional version is called cross-regional update and has its own nuances.

Officially, switching from China ROM to Global ROM is only possible with the bootloader unlocked. If the bootloader is locked, the firmware will issue an error and refuse to install the file. In some cases, but not always, the three-point method works with switching the region in the settings.

• 🌏 Unlock the bootloader through the Mi Unlock service.
• 🌏 Download the full version of Global ROM for your model.
• 🌏 Perform a data cleanup (Wipe Data) before installation.

A reverse switch (from Global to China) is also possible, but less popular. Chinese firmware often comes out earlier and contains exclusive features, but it lacks Google Play by default (although it can be installed) and there may be frequency issues (Band 20).

💡

Change of the firmware region (China) <-> Global) always requires an unlocked bootloader and a complete data reset.

Possible errors and ways to eliminate them

There may be a number of failures during the update process, and one of the common problems is a file verification error or a "failed to update" message, which may indicate a corrupt download file or version incompatibility.

If the phone is stuck on the logo after the bootloop, try entering Recovery mode by pressing the power and volume button. From the Recovery menu, select Wipe Data (data reset) This will delete user information, but often allows the system to boot correctly.

Another problem is loss. IMEI It's a broken communication module, and it happens when modem partitions are not firmware correctly, and then you can only flash the original stock archive over Fastboot with the option. flash_all_except_storage.

⚠️ Warning: Never interrupt the firmware process, even if it seems to be stalled. Interrupting the system file record can irreversibly damage the bootloader.

For diagnosis, use logs that can be obtained through the Service menu and feedback, which often contains information about the reason for the unsuccessful update.

💡

After a major system update (e.g., from MIUI 13 to 14), it is recommended to make a full reset (Factory Reset) to avoid conflicts with old configuration files.
