Xiaomi Mi A3 has become one of the most popular devices in the Android One line, but many users face the limitations of the Chinese version (CN). Transfer of the device to global firmware (Global) opens access to languages, Google services and stable operation of communication modules. This process requires care, but the result is worth it, turning a budget device into a full-fledged international gadget.
Before you start, you need to understand the risks. Any interference with Android One software has the potential to turn your phone into a brick.We’ll look at the safe methods, the tools you need, and a step-by-step algorithm that allows you to upgrade or change the region of your device without fatal errors.
Flashing is not just about copying files, it's about interacting with the bootloader and the memory partitions, and success depends on the quality of the preparation and the strict follow-up of the instructions at each step, and then we'll look at how to prepare the computer and the smartphone for critical changes.
Preparation of equipment and software
The first step is to build the necessary toolkit. You will need an original or quality USB-C cable, as cheap analogues often do not withstand long data transfer and can shut down at a critical moment. The computer must run Windows, since the ADB and Fastboot drivers are most stable in this environment.
You need to install universal Xiaomi USB Driver drivers and the SDK Platform Tools platform on your computer. Without these components, the system will not be able to recognize the device in boot mode. It is also worth downloading the current firmware image from the proven resource, making sure that it is designed specifically for the M1906F9S (Global) or M1906F9SH (China).
- 🔌 Cable USB Type-C with data transfer support (not just charging)
- 💻 PC or laptop with Windows operating system 10/11
- 📦 Archive with platform tools (ADB and Fastboot)
- 🔋 Charged smartphone battery at least 60%
It is important to back up all important data, because when you change the region or unlock the bootloader, you will completely reset your internal memory, and you should transfer your photos, contacts and documents to the cloud server or external drive in advance, and ignoring this step will lead to irretrievable loss of information.
⚠️ Note: Using an unoriginal cable can interrupt power supply during system partition writing, which is fatal for the device.
Unlocking the bootloader (Bootloader)
Official flashing is impossible without an unlocked bootloader. Unlike many other brands, Xiaomi requires a binding Mi Account and a deadline (usually between 7 and 168 hours), a security measure designed to protect users from data theft, but it complicates the preparation process.
To start, activate the developer mode by clicking on the build number several times in the About Phone section. Then turn on the options in the Developer Menu. USB-debugging and unlocking OEM. After that, you need to link an account in the Mi Unlock application on the smartphone itself via the mobile Internet (Wi-Fi will not work).
After the latency has expired, connect your phone in Fastboot mode (clamping the volume down button when turned on) and launch the Mi Unlock utility on your PC. If all conditions are met, the program will prompt you to unlock the device. The process will take a few minutes and will end with an automatic reboot with data cleaning.
⚠️ Warning: Re-locking the bootloader after installing a custom recap or global firmware may result in the inability to boot the system (Bootloop).
It is worth noting that unlocking the bootloader formally violates the warranty, although many service centers turn a blind eye to it unless there is physical damage, but for devices purchased on the gray market, this is the only way to full use.
Installation of custom TWRP Recovery
Standard recovery mode (Stock Recovery) has extremely limited functionality and does not allow you to install modified firmware or make full backups. To work with the Xiaomi Mi A3, it is recommended to install TWRP (Team Win Recovery Project), which allows you to install zip archives, clean partitions and manage the file system.
The installation process is done via the command line. The downloaded twrp.img image file needs to be placed in the folder with the ADB tools. Once you put the phone into Fastboot mode, run the connection check command: fastboot devices. If the serial number is displayed, you can go to the firmware.
fastboot flash recovery twrp_mi_a3.imgAfter a successful recording, it is important to prevent automatic booting to the system, as stock firmware can overwrite the Recovery back. Immediately after completing the command, press the button combination Volume up + Power before the TWRP logo appears.
- 📂 Download the current version TWRP codename laurel_sprout
- 💾 Place the image file in the root of the platform-tools folder
- 🖥️ Open the console in the tool folder and enter the firmware command
- 🚀 Immediately after firmware, perform manual reboot to Recovery mode
In some cases, an encrypted data partition patch may be required so that TWRP can read internal memory.Without this step, you will only see system files, and internal storage will be inaccessible to write firmware.
💡
If TWRP doesn't see internal memory, format Data in the Wipe menu and type "yes." This will delete all data, but solve the encryption problem.
Global firmware installation process
There are two main installation methods: Fastboot (Clean Install) and Recovery (Update), which is preferred when switching from Chinese to global, as it ensures complete cleaning of old settings and conflicts, requiring a firmware archive in.tgz format rather than.zip.
Unpack the firmware archive on your computer. Inside the folder, find the executable file. flash_all.bat (Put your smartphone into Fastboot mode, connect it to your PC, and start the script. 5-10 minutes during which the cable cannot be turned off.
| Parameter | Fastboot Method | Recovery Method |
|---|---|---|
| File type | .tgz (archive) | .zip (installer) |
| Data retention | Complete removal | Possible preservation |
| Risk of error | Low (automated) | Medium (manual actions) |
| Recommendation | To change the region | To update the version |
If you use the method through Recovery, copy the firmware zip file to your phone, log into TWRP, select Install and specify the file. Once installed, make sure to do Wipe Dalvik/Cache. This is a critical step to prevent cyclical reboots.
⚠️ Note: When you run through Fastboot, the script may end up in error if you have non-standard drivers installed on the system. In this case, reinstall Xiaomi drivers manually through Device Manager.
Set up after flashing and fixing problems
Once the new system is successfully installed, the smartphone will restart. The first download can last up to 10-15 minutes — that's okay, there's an optimization of applications and a setup of the database. Don't try to interrupt this process, even if the screen is burning with the Android logo for a long time.
In the initial setup phase, the system may request a Google Account Confirmation (FRP) if a complete reset has not been performed before flashing, and it is also worth checking the sensors, microphone and camera, as in rare cases additional patches may be required to properly work the iron with global firmware.
To check the firmware version, go to Settings → About Phone. Make sure the build number matches the global version (MI or GLOBAL end). If you plan to use banking applications, you may need to reconfigure Google Pay or use security highways if the system partition has been changed.
☑️ Final check
If you have problems with Wi-Fi (missing address or permanent outages), reset your network settings or reflash the communication module, although this is rare on the Mi A3 when using official images. The main thing is to make sure you do not confuse the firmware for different revisions of the device.
