How to properly upgrade your Xiaomi phone: the full guide

Modern Xiaomi smartphones require regular attention not only in terms of physical cleaning, but also software. The release of new versions of MIUI or the latest HyperOS brings not only visual changes, but also critical security patches, battery optimization and new camera features. Ignoring these updates can lead to a decrease in device performance or vulnerability of personal data to viruses.

The process of updating the firmware on the Chinese giant’s devices often raises questions among users, especially when switching between major versions of Android. Mistakes in this process can lead to data loss or, in the worst case, to the transformation of the smartphone into a “brick.” However, if you follow a clear algorithm of actions and understand the differences between types of updates, the procedure is quick and painless for the owner of the gadget.

In this article, we will discuss in detail all available methods for installing a new version of the operating system. We will look at both standard methods through the settings menu and manual installation of archives, which is especially true for devices that for some reason do not receive automatic notification. It is important to understand that manual installation of Recovery firmware does not require unlocking the bootloader, unlike FastROM.

Preparation of the device for installation of a new version of the software

Before you start any process involving flashing system files, you need to do a lot of preparation, and it's not just a formality, it's a mandatory step that minimizes the risk of errors, and you should first make sure that the battery is at least 60%, and ideally, connect the device to the power source throughout the procedure.

The second critical step is to back up your data. Even if the update is regular, there is always a minimal risk of file system failure. Use the built-in Mi Cloud or third-party services to save contacts, photos and important documents. Also make room in internal memory: it can take 3 to 10 GB of free space to download and unpack the service pack.

Trying to install the firmware designed for the Xiaomi Redmi Note 10 on the Xiaomi Mi 11 will lead to a fatal error. The exact model can be found in the Settings → About Phone section. It is also recommended to disable third-party antivirus and memory cleaners that can block system installation processes.

⚠️ Note: If your device has superuser rights (Root) or unlocked the bootloader, the standard OTA-The update may not be installed or result in a cyclical reboot, in which case a complete flashing through the computer is required.

Automatic update via the settings menu (OTA)

The easiest and safest way to get a new version of software is to use the built-in OTA (Over-The-Air) mechanism. The system itself checks the servers for new packages and offers them to the user. To start the process, just go to Settings → About Phone → MIUI version (or system logo).

If the update is available, a notification will appear with the version number and packet size. By clicking the Download button, the phone will start downloading the archive. The speed depends on your Internet connection, so it is recommended to use the Wi-Fi network to avoid wasting mobile traffic. After downloading, the system will suggest restarting and starting the installation.

Sometimes the notification doesn't come, even though it's already there on other devices in your model, so you can try clicking on the three dots in the top right corner of the screen and select "Select a firmware file" if you already have a downloaded archive. Or just wait a few days, because (push) notifications often happen in waves.

💡

Use the Preload feature in the update settings to download the package at night when the internet is more stable and install it in the morning.

Manual installation of firmware through Recovery

If the automatic method doesn’t work or you want to upgrade to a specific version that the system doesn’t offer yet, you can use the manual method. This requires downloading the.zip (Recovery ROM) firmware archive from the official website or proven resources.

Copy the downloaded file into the phone's internal memory. Then go to the update menu: Settings → About Phone → MIUI version. Click three dots and select "Select firmware file." The system will find the archive and prompt you to start the update. The phone will reboot to Recovery mode and begin the installation process.

The good thing about this method is that it doesn't require a computer connection and works even on unstable Internet (since the file is already downloaded), but if you're trying to roll back to an older version of the system, it may not work without completely cleaning up the data or using special tools.

Update via computer with the Mi Flash Tool

For advanced users and situations where the phone is “buzzed” or requires a clean installation of the system, the Mi Flash Tool is designed. This method requires connecting a smartphone in Fastboot mode. To enter this mode, you need to turn off the phone and simultaneously press the power and volume down buttons until a rabbit appears in a hat-eared.

The installation process is as follows:

• 📥 Download and install drivers ADB Mi Flash Tool on the computer.
• 💾 Download the Fastboot firmware (.tgz extension) and unpack the archive to the root of the C disk so that the path does not contain Cyrillic.
• 🔌 Connect your phone to your PC through quality USB-cable, pre-transferring it to Fastboot mode.
• 🖥️ Launch the Mi Flash Tool, click Refresh and select the path to the firmware folder.
• 🚀 Click Flash and wait until the process is over (green bar).

Using this method gives you complete control over the process. You can choose the cleaning mode: "Clean all" (saves data but clears the cache), "Clean all and lock" (full reset and lock the bootloader) or "Save user data" (attempt to save data, but not recommended when changing the region). Fastboot mode operates at a low level, so interruption of the process is most dangerous here.

⚠️ WARNING: When using the "Clean all and lock" option on devices with an unlocked bootloader or global firmware on a Chinese device, the phone can be locked permanently.

Solving Common Problems When Updating

Even with all the instructions, there can be unexpected situations, and one of the most common problems is the endless bootloop cycle after installation. If the phone is stuck on the MI logo for more than 10 minutes, try to force the reboot by holding the power button for 15-20 seconds.

Another common error is the message “Can’t check the update,” which often happens when you use modified firmware versions or have root rights, in which case cleaning the Update app cache through the app menu or completely flashing it through your computer helps.

If the phone starts to run out quickly or run slowly after the upgrade, give it 1-2 days to optimize the background processes. The system reconfigures the app caches for the new version of Android. If the problem persists, you may need to reset to factory settings, but only after you create a full backup.

💡

Most update errors are due to a erratic internet or memory shortage, so always check these settings before starting the procedure.
