Preparation of the device and choice of method
The first step is to determine the current status of your Xiaomi smartphone. You need to know whether the bootloader is unlocked, as the available installation method depends on it. For Xiaomi.eu firmware, unlocking the bootloader is a must, without it, you can not install a custom build.
There are two main ways to upgrade: through the built-in Recovery menu (the easiest one) and through a computer using Fastboot. The first method is suitable for switching between neighboring versions or major updates within the same Android branch. The second method is necessary if you change the version of Android (for example, from 14 to 15) or restore the system after a crash.
It is important to download the correct firmware file. Recovery files have a.zip extension and weigh about 5-6 GB, and Fastboot files are.tgz and can take up to 8 GB. Always check the checksum of the file after download to ensure that data is not damaged when downloaded.
- 📱 Make sure the battery is at least 60%.
- 💾 Free up at least 10 GB of internal memory before downloading the file.
- 🔓 Check the bootloader unlock status in the Settings menu → The phone. → Version. MIUI (press 7 times).
- 🌐 Use a stable Wi-Fi connection to download the system image.
Update via the Recovery menu (Zip file)
This method is most popular among Xiaomi.eu users due to its simplicity and lack of need for a computer.It is ideal for scheduled updates when you upgrade from, for example, version 24.1 to 24.2.
After downloading the archive eu_version.zip Go to the update menu. In some versions of the interface, you need to click on three dots in the corner of the screen and select "Select firmware file." The system will check compatibility and prompt you to start the process. If the file is damaged or not suitable for your model, the update will not begin.
☑️ Checklist before firmware through Recovery
During the installation process, the phone will reboot several times. The screen can go out and light up — that's normal behavior. Don't try to interrupt the process or take out the battery even if it seems like the phone is frozen. Modern systems have protection mechanisms, but physical interruption of data recording is fatal.
⚠️ Note: If after installing the new version of the phone goes into a cyclic restart (bootloop), you will need to reset (Wipe Data) through the Recovery menu.
Installation via Fastboot (for PC)
Fastboot is more reliable and versatile, not only allows you to update the system, but also completely clear the memory partitions, which eliminates the compatibility of old settings with new software. ADB/Fastboot, Mi Flash (or command line) and cable USB Type-C high-quality.
First, turn your smartphone into Fastboot mode. To do this, press the volume button and connect the cable to your computer. The screen will show an image of a rabbit repairing an android. In the PC command, type in the command of fastboot devices to check the connection.

Once you hit the custom recavator, select Install, specify the path to the downloaded zip archive, and confirm the action with the swipe.
- 🖥️ Install current Qualcomm or MediaTek drivers for your model.
- 🔌 Use the original cable or certified analogue.

|---|---|---|---|
| I need a PC. | No. | Yes. | No. |

| Difficulty | Low. | Tall. | Medium |
| Time of installation | 10-15 minutes. | 20-30 minutes. | 15 minutes. |
| Risk of error | Medium. | Low (with proper preparation) | High (if the file is wrong) |
💡
To switch between different versions of Android (for example, from 14 to 15), always use the method with a complete data cleanup to avoid system conflicts.
Decision errors in the update
Even with careful preparation, unexpected situations can occur, and one of the common problems is the error "Can't verify update", which means that the digital signature of the file does not match the expected, which often happens when a file is downloaded from an unreliable source or interrupted download.
Another problem is getting stuck on the MIUI logo or the Android logo. If the phone doesn't boot for more than 10 minutes, you need to enter Recovery mode and perform a Wipe Data reset, which will delete all user data, but will restore the system to work.

First Startup and Optimization of the System
Once installed successfully and first enabled, Xiaomi.eu will begin a long-term application optimization process that can take anywhere from 5 to 20 minutes depending on the processor model and the number of programs installed, and it is absolutely impossible to interrupt this stage.
Newer versions of HyperOS or MIUI often change the layout of interface elements, it is recommended to immediately check the privacy settings and permissions for applications, and it is also worth updating all system applications through the GetApps store or Google Play, as the latest versions may not come with firmware.
To maximize stability on the first day after the upgrade, try not to load the device with heavy games. Give the system the ability to rewire the cache and adjust the background processes. If you move from a very old version, some applications may require reinstallation to work properly.
