Owning a Xiaomi Mi 9 is a great experience with flagship hardware, but users often encounter a Chinese version of firmware that lacks the usual interface and services. Russification in this context involves not just a menu transfer, but a complete replacement of the software shell with a global or localized version.
Before you start taking action, you need to realize that any manipulation of the software carries risks. Self-flashing Xiaomi Mi 9 will void the official manufacturer's warranty, if it was still valid at the time of work. However, for enthusiasts, this is the only way to unlock the potential of the device, gaining access to Google Play, Russian language in the system and the absence of intrusive advertising.
Next, we'll look at a step-by-step algorithm that will make a Chinese gadget a complete tool for life. It's important to follow the sequence of steps, because disrupting the order of operations can lead to the inoperability of the device. Bootloader is the first line of defense that we have to overcome.
Preparation of equipment and software
Successful Russification Xiaomi Mi 9 directly depends on the quality of the workplace. You will need a smartphone with a charged battery of at least 60%, a computer running Windows and high-quality USB-Using cheap charging cables often causes a connection to break at a critical moment, which can turn the phone into a brick".
You need to install ADB and Fastboot drivers on your computer, which allow the OS to recognize your smartphone in different boot modes, and you need an archiver to unpack your firmware files and a utility to unlock the Mi Unlock bootloader, without which you can't do anything.
For Xiaomi Mi 9 (codename cepheus), the official global versions or builds from the Xiaomi.eu community are best suited. The latter are devoid of Chinese software, optimized for European regions and have built-in Russian.
Check the integrity of downloaded files. A damaged firmware archive can cause installation errors even if the process seems successful in the initial stages. Make sure there is enough free space on disk C for temporary files.
Unlocking the bootloader (Bootloader)
The first and most important step is unlocking the bootloader. Bootloader is a program that runs before the operating system is turned on and checks the integrity of the system. It is blocked by default, which prevents the installation of modified software.
First, you need to link your Mi Account to your device. → About the phone and several times click on the version MIUI, To activate the developer menu. Then go to Settings. → Advanced settings → For developers and include the items "Factory unlocking" and "Debugging by USB".
In the same menu, find the item "Mi Unlock Status." Click on it and select "Add Account and Device." The system will request confirmation via SMS. Once the link is successful, you need to wait a certain time — usually 168 hours (7 days), although sometimes the period is reduced to 36 hours.
⚠️ Warning: The unlocking process will completely clear all data on your phone. Backup your contacts, photos and important documents in the cloud or on your computer in advance.
When the wait period expires, turn off your smartphone and enter Fastboot mode, holding the power and volume buttons simultaneously. Connect your phone to your PC, launch the Mi Unlock Tool, log in to your account and press the unlock button.
☑️ Checklist before unlocking
Installation of custom TWRP Recovery
Xiaomi’s regular Recovery menu has limited functionality and does not allow third-party firmware installation. We will need TWRP (Team Win Recovery Project) – an advanced menu with support for touch control and advanced features.
Download the current version of TWRP specifically for the Xiaomi Mi 9 model (codename: cepheus). The file will have the.img extension. Place it in the folder with ADB tools on your computer for convenience. Rename the file to twrp.img so you don't get confused with commands.
Put your smartphone into Fastboot mode (power buttons and volume down) and connect to your computer. Open the command line in the ADB folder and enter a command to check the connection:
fastboot devicesIf you get the serial number of the device, you've got the link, and you've got to flash the Recovery with the command:
fastboot flash recovery twrp.imgAfter successful firmware, you can't just reboot your phone in the usual way, otherwise the regular Android will overwrite the TWRP back, and you need to immediately switch to the recovery mode without releasing the buttons.
What if TWRP is not saved?
Process of installation of firmware and localization
Now that we have access to TWRP, you can start installing a Russified system. Copy a pre-downloaded firmware zip archive (e.g., Xiaomi.eu) into your phone’s internal memory or a connected flash drive.
Boot to TWRP (press the power and volume up). First, clear the partitions. Select Wipe, then Advanced Wipe, and mark Dalvik, Cache, System, Data. Don't touch the Internal Storage section, or you'll lose your firmware files.
Once cleaned, go back to the main menu and select Install, find the firmware file and confirm the installation with the swider, the process will take a few minutes, at which time the log of operations will be displayed on the screen.
| Section | Action. | The result |
|---|---|---|
| Dalvik / ART Cache | Wipe | Cleaning up the app cache |
| System | Wipe | Removal of the old system |
| Data | Wipe | Complete reset of user data |
| Internal Storage | Don't touch it. | Saving firmware files |
When you complete the installation, press Reboot System. The first run can last up to 5-10 minutes, which is normal for a new system. After downloading, you will be met by the original setup wizard in Russian.
Google Services and Security
In global and custom firmware for Xiaomi Mi 9, Google services are usually built-in by default. However, in some cases, you may need to manually activate or update components. Go to Settings → Accounts and Sync and add your Google account.
Security is a particular concern. Because the bootloader is unlocked, the system may flag some banking applications as potentially dangerous. Google Pay (now Google Wallet) and banking programs often require hiding root access rights if they were obtained, or using Magisk Hide modules.
💡
Use the Google Play Protect app to scan your system regularly for malware, especially if you install apps from third-party sources.
You should also set up biometric protection. Xiaomi Mi 9 is equipped with an ultrasonic underscreen fingerprint scanner and facial recognition system. Set these settings in the Passwords and Security section for quick access.
⚠️ Warning: Do not install dubious applications with superuser rights from unverified sources, which can disrupt security and make it impossible to use bank cards.
Possible mistakes and ways to solve them
Russification doesn't always go smoothly. One of the common problems is Bootloop. If your phone is stuck on the Mi logo, try re-entering the TWRP and making a full Wipe, then reflashing the device.
Another common mistake is a broken touch screen in TWRP. This happens if the version of the recovery does not match the Android version or screen type (screen manufacturers in the same model may differ), in which case you need to find an alternative TWRP build that is compatible with your revision of the display.
Problems with Widevine L1 (Netflix video quality) are solved by firmware on original data files or by restoring a backup of EFS if it was made before unlocking. Without this, streaming services can limit quality to SD.
💡
Most of the errors in the Xiaomi Mi 9 firmware are solved by re-cleaning the partitions and using a strictly compatible version of TWRP and firmware.
If the phone stopped responding to buttons and does not turn on (EDL mode), you will need a specialized cable to enter deep boot mode and an authorized Mi Account to run through the Mi Flash Pro utility.
