Changing the software shell of a smartphone is a powerful tool that allows not only to update the interface, but also to bring the device back to life after unsuccessful experiments. Owners Xiaomi, Redmi and Poco often face the need to switch from the Chinese version of firmware to the global one or restore the system after a failure. The process of flashing it may seem difficult only at first glance, but with strict adherence to the algorithm of actions it becomes available even for inexperienced users.
Before you start taking action, you need to be clear about the risks and prepare the software environment. Firmware is a low-level operation, interruption of which can lead to the fact that the phone turns into a “brick.” Modern Xiaomi devices have several levels of protection, including locking the bootloader, which will have to be bypassed legally, in this article we will examine all the steps from obtaining rights to the final installation of the system image via Fastboot or Recovery.
Preparation of the device and obtaining rights
The first and most important step is unlocking the bootloader. Without this procedure, installing third-party images or even official global versions will not be possible instead of Chinese. Xiaomi has implemented this security measure to prevent device theft and malware installation. First, you will need a Mi Account that must be linked to the smartphone.
The waiting process can take 7 to 168 hours (usually 7 days) and Xiaomi’s security system needs to check the device for theft, during which time the unlocker will give an error and try to bypass the timer will not lead to anything.
⚠️ Warning: The process of unlocking the bootloader automatically performs a full data reset (Wipe Data). be sure to back up all important photos, contacts and documents before starting the procedure.
To perform the preparatory work you will need:
- 📱 Smartphone with a battery charge of at least 60%
- 💻 Computer running Windows (for utilities)
- 🔌 Original. USB-cable
- 🌐 Stable Internet connection for communication with Mi servers
☑️ Checklist for firmware preparation
Once successfully unlocked, the bootloader menu will display a distinctive sign that says Unlocked in orange or blue, which signals that the path to system modification is open, and you can now move on to choosing the type of firmware that will depend on your goals and device model.
Selection of firmware type: Global, CN or Custom
Understanding the differences between operating system versions is critical to the correct operation of the smartphone after flashing, and official images are divided into several categories, each of which has its own characteristics in terms of preinstalled software and supported communication frequencies.
Global ROM is an international version optimized for use outside of China, which contains a full range of Google services, a multilingual interface (including Russian), and the correct LTE/5G frequency settings for European and Russian operators. China ROM, on the contrary, is devoid of many global applications, has Chinese and English languages, and can work incorrectly with some communication bands.
There is also a division by the method of updating:
- 🚀 Recovery is the standard method of updating "over the air" or manually through the recovery menu. does not require an unlocked bootloader (if the version of the region matches the same).
- ⚡ Fastboot is a method of complete flashing over the PC. requires an unlocked bootloader and allows you to change the region (for example, from China to Global).
The choice between stable and beta depends on your tolerance for errors. Stable builds are less common but guarantee reliable performance. Developer/Beta versions are updated weekly and contain the latest features, but may have unstable code.
⚠️ Note: When trying to install Global firmware on a Chinese device via Recovery (without complete cleaning), a bootloop cycle is possible. Always use the Fastboot method with full data cleaning to change region.
Required tools and drivers
High-quality software preparation on the computer is the key to successful firmware. You will need not only the firmware utility itself, but also the right drivers that will ensure communication between the PC and the smartphone in various modes of operation.
The main tool for working in Fastboot mode is the Mi Flash Tool. This is the official utility from Xiaomi, which allows you to download system images to the memory of the device. Recovery mode is enough to have a firmware file with the extension.zip and a built-in recovery menu.
The critical thing is to install the drivers, and without them, the computer won't see the phone in the right mode.
- 🔧 Drivers. ADB Fastboot (usually included in the SDK Platform Tools)
- 📱 Qualcomm or MediaTek drivers (depends on your smartphone’s processor)
- 🖥️ Xiaomi drivers USB (to correctly define the device in the system)
Where do I download the drivers?
After installing all the components, it is recommended to restart the computer. You can check for drivers in the Device Manager: when connecting a phone in Fastboot mode, an Android Bootloader Interface device without exclamation points should appear in the list.
Firmware via Recovery Menu (without PC)
This method is suitable for updating the system version within the same region or installing the official firmware if the bootloader is unlocked.
First, you need to download the firmware file in.zip (Recovery ROM) format for your particular model, put the file in the root of the device's internal memory, then put the smartphone into recovery mode, to turn off the device and pinch the combination of the Volume + and Power keys.
In the Recovery menu, you can control volume buttons (up/down) and power button confirmation. On some touch-sensitive Recovery devices, you can control directly over the screen. Select the language (if available), then Wipe Data (clean up) and confirm the action.
| Action. | Description | Risk of data loss |
|---|---|---|
| Wipe Cache | Clearing temporary files | No. |
| Wipe Data | Complete resetting of settings | Yeah (all deleted) |
| Connect with MIAssistant | Debugging mode via PC | No. |
| Reboot | System restart | No. |
Once the data is cleared, go back to the main menu and select Install from zip (or similar). Find the previously downloaded firmware file and confirm the installation. The process will take 5 to 15 minutes. Once completed, select Reboot to System.
💡
If you've been running your phone through Recovery for up to 10 minutes, don't panic. It's doing application optimization and partitioning. Wait for the Mi logo to come out.
Installation of firmware through Fastboot (Mi Flash Tool)
This is the most versatile and powerful method to completely replace software, change region and fix critical system errors, and you will need a.tgz (Fastboot ROM) firmware file to unpack on your computer.
Put your smartphone into Fastboot mode by pressing the Volume and Power buttons on the device turned off. Connect your phone to your PC with a cable. Launch the Mi Flash Tool on behalf of the administrator. Press the Refresh button to allow the program to detect the device (its serial number will be displayed).
In the program interface, select the path to the unpacked firmware folder. Pay attention to the choice of firmware method at the bottom of the window:
- 🟢 Clean all – complete data cleanup and installation (recommended when changing region).
- 🔵 Save user data - data storage (only possible when you have firmware in the same region).
- 🔴 Clean all and lock – cleaning and re-locking of the bootloader (dangerous when changing the region!).
⚠️ Warning: Never select “Clean all and lock” if you change your firmware region (e.g. China to Global) and this will result in a hard-lock device (Hard Brick) that can only be removed through paid service tools.
Press Flash and wait until the process is over. Success status on the last line means successful completion. The phone will automatically reboot.
💡
Using the Fastboot method with the Clean All option is the most reliable way to fix software bugs and change region, but it is guaranteed to delete all your data.
Possible mistakes and ways to solve them
The firmware process doesn't always go smoothly. Users can encounter errors at different stages. Understanding the error codes helps quickly diagnose the problem and fix it without going to the service center.
One of the most common problems is the Mi Flash Mi Flash Mi Mi-Mixing Image and Device error, which means you are trying to flash a firmware designed for another model. Always check the device's codename (e.g., davinci, ursa, vayu) before downloading files. There is also a possible Flash Error error when it is unstable. USB-connection.
If the phone goes into an endless bootloop after firmware, try the following steps:
- 🔄 Press the power button on 15-20 second-on-seconds.
- 🧹 Go to Recovery and do the full reset (Wipe Data) again.
- 💾 Try reflashing the device via Fastboot again, changing USB-port.
What if Mi Flash can't see your phone?
In rare cases, especially when the recording process is interrupted, the device can go to EDL (Emergency Download Mode) mode. This screen usually only lights the power indicator or shows a cable.
