Owning a modern smartphone involves getting regular software updates that not only add new features, but also close security vulnerabilities. For users of the Xiaomi ecosystem, this process can range from simply pressing a button to complex manual flashing through a computer, especially if the device does not receive updates through the air in your region. Understanding the differences between the global and Chinese versions of the firmware, and knowing the algorithms of the bootloader, is critical to successfully complete the procedure without losing data.
In this article, we will discuss in detail all available methods of software update: from the regular OTA-Update to forced installation of the archive through Recovery mode, you will learn how to prepare the gadget for the procedure, what tools will be needed to work with Fastboot, and what to do if the process went wrong. Competent approach will extend the life of your device and access the latest features of the HyperOS shell or MIUI long before the official mailing.
Why you need to update Xiaomi firmware and what it gives
Regular updates to your system software aren’t just a way to get new emojis or widgets on your desktop, but first and foremost, the company’s engineers are releasing security patches that fix Android security holes that could allow attackers to access your personal data, banking apps and passwords. Ignoring these updates makes your smartphone a vulnerable device, especially when using public Wi-Fi networks.
In addition, new versions of the shells MIUI And HyperOS often includes power and processor optimization, and older users may notice that the battery runs out faster and applications are delayed, whereas after a fresh patch is installed, the system starts to run smoother. Also updates often fix camera bugs, Bluetooth connections and module operation. GPS, which cannot be eliminated by simply resetting the settings.
It is worth noting that the transition to the major version of Android (for example, from 13 to 14) is often accompanied by a change in the architecture of the system, which requires more careful preparation. If you use important applications for work or banking services, timely updates ensure their correct operation, as software developers gradually stop supporting older versions of the OS.

Before a major update, back up important contacts and photos to Google’s cloud or your computer, even if you plan to save data.
Preparation of the device before the procedure
Before you start any manipulation of system files, you need to perform a number of preparatory steps that minimize risks.The first and most important rule is to charge the smartphone battery to at least 60-70%, as the installation process can take from 15 minutes to an hour, and a sudden power outage at a critical moment can lead to the buildup of the device.
The second step is to free up storage. Even if you download the update over the air, the system requires space to unpack the archive and temporary files, it is recommended to have at least 5-8 GB of internal memory free, and it is also worth checking the stability of the Internet connection if you plan to download the file directly through the phone menu.
☑️ Preparations for renewal
Don’t forget to back up your data. Xiaomi’s built-in tools allow you to save your application list, settings and system data to the Mi Cloud or external media. For photos and documents, you should use Google Photos or transfer them to your computer, as when you move between different firmware regions (for example, from CN to Global), the data can be deleted.
⚠️ Warning: Unlocking the bootloader to install global firmware on the Chinese version of the device results in a complete reset of all data (Factory Reset).
Method 1: Automatic Air Update (OTA)
The easiest and most secure method available to every user is to update through the built-in OTA (Over-The-Air) mechanism, which checks the servers for a new version of the software that is suitable for your model and region. To start checking manually, go to Settings → About phone and click on the logo of the version of MIUI or HyperOS.
If you find an update, the phone will prompt you to download and install it. In the background, the archive will load, after which you will need to restart. During installation, the logo and progress bar will be displayed on the screen - at this point you absolutely cannot interrupt the process or turn off the phone. Once completed, the device will restart with the new version of the system.
Sometimes the notification doesn't come, even though your model has already been updated, so you can try changing the region in the settings (Settings → Additional settings → Region) to India or Indonesia, check for updates, and then return your region, a trick that often helps rock the server and get the file to install.
💡
The OTA method stores all user data and settings, being the most preferred for ordinary users.
Method 2: Manual installation via Recovery (without PC)
If the automatic update doesn’t work or you want to install a specific firmware version (for example, roll back or go to early access), you can use the method of manual installation of the archive. You will need to download the firmware file in.zip (Recovery ROM) format strictly for your model from the official site or trusted resources.
After downloading the file, go to Settings → About Phone and click on the system version several times to open the extended menu. Select three dots in the corner and click "Select firmware file." Specify the downloaded archive and the phone will suggest restarting to start the installation. This method also usually passes without losing data.
What if the system says “I couldn’t check the file”?
It is important to understand the difference between firmware types: Recovery ROM (for installation via the phone menu) and Fastboot ROM (for installation via a computer, has the.tgz extension). For the described method, only the first type is suitable. Make sure that the file name matches your device (for example, Xiaomi 13 has the code name fuxi).
Method 3: Update via computer in Fastboot mode
The most powerful and versatile way to restore the brick, change the firmware region or update a device that does not boot, USB-cable, drivers ADB/Fastboot The firmware file must be in.tgz format (Fastboot). ROM) and fully unpacked on the computer.
Put your smartphone into Fastboot mode, holding both the power and volume buttons when the device is turned off (there will be a hare in an eardress hat fixing an android on the screen). Connect the phone to your PC, launch the Mi Flash Tool, press "Refresh" to determine the device, and select the path to the firmware folder. Before starting, select the firmware mode at the bottom of the window.
The program has three options: clean all (complete data cleanup), save user data (attempt to save data) and clean all and lock (clean and lock the bootloader), the latter option is recommended to use only when installing official global firmware to avoid startup problems.
| Parameter | Recovery ROM (.zip) | Fastboot ROM (.tgz) |
|---|---|---|
| Method of installation | Through the phone menu | Through PC and Mi Flash Tool |
| Data retention | Usually, it's | Depends on the chosen mode |
| Change of region | Limited (Global) ↔ Global) | Possibly (CN ↔ Global)* |
| Difficulty | Low. | Tall. |
⚠️ Note: When you run through Fastboot with the "Clean All and Lock" option on a device with the bootloader unlocked, it can lead to a check error and system failure to boot.
Common mistakes and ways to solve them
During the update process, users often encounter an error such as “Failure to check file” or a logo hanging, and the first problem is usually due to version mismatch: you can’t install an older version on top of the new one without completely cleaning up. There is also an error when trying to install Global firmware in Chinese. ROM loader-free.
If the phone is stuck on the logo after the update (bootloop), try to enter Recovery mode (press the power and volume +) and select Wipe Data. This will delete all data, but often saves the situation if the system files and user settings conflict. Before you do, make sure you have a backup.
Another common problem is the lack of communication with the update server, which can be caused by ISP blocking or temporary problems with Xiaomi servers, in which case using DNS (for example, 8.8.8.8) or switching to the mobile Internet can help download the service pack.
💡
Most update errors are due to space shortage, low battery power, or an attempt to install an incompatible firmware version.
