Many Xiaomi, Redmi and POCO smartphone owners face limitations on standard versions of the MIUI or HyperOS operating system. Global builds often contain pre-installed advertising junk, redundant Google system apps and Chinese services that cannot be removed without root rights. This is where custom firmware from the Xiaomi.eu community comes to the scene, which is an optimized version of Chinese ROM with built-in multilingual Google packages and services.
Moving to this platform is not just a change in appearance, but a fundamental change in the logic of the device: you get access to hidden features, improved autonomy and no intrusive advertising in the system interfaces. The transition process requires care, because it involves completely cleaning the memory of the smartphone and installing a loader other than the factory one.
In this guide, we'll take every step of the way, from applying for an unlock to the first download on an updated system. You don't have to be a professional programmer, but following the instructions is critical. The transition process is irreversible without completely flashing back to the stock version, so prepare yourself in advance.
What is Xiaomi.eu and why is it necessary?
Xiaomi.eu is based on official Chinese firmware versions, which usually come out earlier than the global ones and contain more features. Community developers integrate language packages, including Russian, add Google Play services and remove everything superfluous, which annoys the European user. Unlike stock Global ROM, you will not find ads in standard applications like Music or Explorer.
Optimization is a key advantage: Chinese versions of MIUI aggressively manage background processes, which, in conjunction with European patches, gives you an increase in battery life. In addition, eu builds often contain exclusive themes, fonts and interface settings that are not available in official releases for other markets, which makes the interface more flexible and personalized.
But the difference between Custom ROM and modified runoff is clear: Xiaomi.eu is not a third-party Android (like LineageOS), but a deeply refined original system that ensures full compatibility with all the hardware on your smartphone: the camera, NFC, sensors and fast charging work normally, without the bugs that characterize complete kernel reassemblies.
Preparation of the device and unlocking the loader
The most difficult and important step is unlocking the bootloader. Without this procedure, installing the custom TWRP and the firmware itself is impossible. Note that once unlocked, all data on the phone will be deleted, and warranty in some regions may be formally lost, although flashing to the stock version returns everything as it was.
To start, you need to install the official Mi Unlock Tool on your Windows computer. Also, on the smartphone itself, you need to activate the developer mode. Go to Settings → About the phone and quickly click 7 times on the version number of MIUI. After the notification “You became a developer”, go to the advanced settings and select For developers.
In the developer menu, find the item "Mi Unlock Status" and click "Add Account and Device." The system will link the current Mi Account to the hardware of the smartphone. This is a mandatory security condition. Once attached, it may take a wait from 7 to 168 hours (usually 7 days) before the Xiaomi server allows the unlock.
☑️ Checklist before unlocking

Launch the Mi Unlock Tool, log in to the same account and press the Unlock button. The process will take a few minutes, after which the phone will restart and clear the data.
Installation of TWRP Recovery
After successful unlocking, the standard recovery menu is replaced with a custom one. TWRP (Team Win Recovery Project allows you to install firmware manually, make full system backups and clean up memory partitions. You can download the current version of the image (.img) for your model on the official project forum or in the branch of your device on the site. 4PDA/XDA.
For installation TWRP Put your smartphone back in Fastboot mode. Connect it to your computer and open the command line in the folder with the installed ones. ADB-The installation command is as follows:
fastboot flash recovery name file twrp.imgAn important nuance: after executing the command, you can not just reboot the phone into the system in the usual way, otherwise the stock recap will overwrite TWRP. You must immediately press the Volume Up + Power buttons and hold them until the Mi logo appears. If you saw the TWRP menu with Wipe, Install, Backup buttons, everything was successful.
💡
If after installing TWRP, the phone goes into a cyclic reboot, try flashing the image again, after executing the command fastboot erase recovery.
Inside TWRP, the interface may be in English, but it's intuitive. Before installing a new system, make sure to back up the current firmware through Menu → Backup, which will save you in case the new version is unstable or you want to go back.
The process of installing the firmware Xiaomi.eu
The firmware file is extended to zip and usually weighs between 4 and 6 GB. Download the current version for your model (device encoding, for example, guava for Redmi Note 9 Pro) and place it in the phone’s internal memory or on the phone. USB-flash drive, if you use it OTG-Adapter, load in. TWRP.
The first step is to clean up the data (Wipe), which is a critical step when you transition between different types of firmware (for example, from Global to China-based EU). In the Wipe menu, select Advanced Wipe and tick the sections: Dalvik / ART Cache, Cache, System, Vendor and Data. Don't touch Internal Storage, otherwise you will lose the firmware file!
💡
Clear Install is a must when switching from Global ROM to Xiaomi.eu to avoid system libraries and bootloops conflicts.
Once cleaned, go back to the main menu and select Install. Find the downloaded zip file with the firmware and confirm the installation of the slider swipe. The process will take 5 to 15 minutes. At this time, the installation log will be displayed on the screen. When completed, click Reboot System.
The first run can last up to 10 minutes. Don't panic if you see the MIUI logo or Xiaomi logo, the system is customizable. Once you boot, you'll be greeted by a clean desktop with no extra trash. First, check the version in the About Phone settings, it will say "Xiaomi.eu."
Configuring after installation and first steps
Once installed, the system may not be quite stable due to database optimization and application compilation in the background, so let the phone lie on charge for about 30-60 minutes after first turning on, and this will allow the Dalvik cache to form correctly.
There are a lot of useful features hidden in Xiaomi.eu settings. Go to Settings → Advanced Settings → Experimental features. You can activate a free window, secondary space, or change the behavior of navigation buttons. It is also worth looking at the settings of those where hundreds of free designs are available, not available in global versions.
