Changing the software shell of a smartphone is often a necessity when a device purchased in China does not support Russian or applications important for the operation. Global firmware provides full interface localization, the presence of Google services out of the box and correct notifications. Owners of Redmi and Poco models often face the limitations of the Chinese version of MIUI or HyperOS, which makes the issue of firmware reflashing relevant.
The process of transitioning to Global ROM requires care, as incorrect actions can lead to data loss or software failures. There are several proven methods of updating: through the standard settings menu, Recovery mode or using the computer and the Mi Flash Tool utility. The choice of the specific method depends on the current version of the software and whether the bootloader of your device is unlocked.
In this article, we will discuss in detail the algorithms of actions for each method, paying special attention to the nuances of unlocking Bootloader and choosing the right firmware archive. Xiaomi constantly changes the security policy, so it is important to use the latest tools. Proper preparation of the gadget ensures the successful completion of the procedure without the need to contact the service center.
Determination of the current version of the software and preparation of the device
Before you start any manipulation, you need to know exactly which operating system is installed on your smartphone at the moment. This is critical, since switching from the Chinese version (CN) to the global version (Global) often requires unlocking the bootloader, while updating within one region can pass without complex procedures. Go to the Settings menu → About the phone and carefully study the line with the version of MIUI or HyperOS.
If you have an RU or EU alphabet at the end of the version name, and you have the word Global, you already have an international version installed. If you see CN characters or Chinese city names (e.g. Beijing), you have a Chinese build. You can't upgrade directly from CN to Global via Recovery without unlocking the bootloader and you will make an error.
Make sure to back up all your important data, as the process of changing the regional version almost always involves a complete reset of your device’s memory. Use Google’s cloud services or Xiaomi’s built-in backup tool to save contacts, photos and app settings. Also make sure that your battery is at least 60% so that your device doesn’t turn off at a critical time.
You will need a stable internet connection to download the required files and a Mi Account linked to the device. SIM-card SMS-- Prepare a quality code for the unblocking confirmation code. USB-cable, preferably original if you plan to use a computer for firmware.
Necessary tools and software
To do this successfully, you'll need a suite of specialized software that you can find on official resources or trusted forums. The main tool for working with devices based on Qualcomm and MediaTek processors is the Mi Flash Tool. It allows you to install system images in Fastboot mode, which is the most reliable, but also the most risky method.
You also need to download the current ADB and Fastboot driver so that the computer correctly recognizes the smartphone in service modes. Without installed drivers, the system will not see the connected device, and the process will not begin.
- 📱 Smartphone Xiaomi/Redmi/Poco battery-charged 60%.
- 💻 PC or laptop running Windows (versions 7, 10 or 11).
- 🔌 USB-a well-shielded cable that supports data transmission.
- 📂 Firmware archive (Fastboot or Recovery) for your specific model.
- 🔓 Unlocked loader (for transition between regions).
It is important to understand the difference between firmware types: Recovery (extension.zip) is installed through the recovery menu, and Fastboot (extension.tgz) is installed only through the computer. The most common way to switch from China to Globalka is to use the Fastboot version with the unlocked bootloader. Carefully check the file name so you don’t confuse the versions.
☑️ Firmware readiness check
Unlocking the bootloader (Bootloader)
The most difficult step for many users is to unlock the bootloader, which is mandatory for changing the firmware region. Xiaomi has implemented this security measure to prevent theft of devices and installing modified software. The procedure requires submitting an application through a special application Mi Unlock and waiting for a certain period of time, which can be from 3 to 7 days.
First, you need to log into your Mi Account in your phone settings and link the device to that account. → For developers, you should activate the Factory Unlocking item (OEM After that, the smartphone must be transferred to Fastboot mode, holding the power and volume buttons simultaneously when the device is turned off.
⚠️ Warning: The bootloader unlock process automatically resets all data (Wipe Data). save all important files, photos and contacts in advance, as it will be impossible to restore them after unlocking.
Once you submit your application in Mi Unlock, you will have to (wait) for the allotted time on your computer. Repeated attempts to apply early can reset the waiting timer. Successful unlocking is confirmed by the appearance of an open lock icon when you boot the device and in the unlock application.
Some older models or specific versions of software may have limitations on unlocking, and in such cases, standard methods may not work and you may need to find alternative solutions or wait for company policy updates. Always check the status of your device on the official forum before you start actions.
What if Mi Unlock can’t see the phone?
Recovery Update Method (without PC)
This is a good way to upgrade within a single region or install an official global firmware if the bootloader is already unlocked. You will need to download the firmware archive in Recovery format (usually a file with the.zip extension) and place it at the root of the smartphone’s internal memory. Rename the file to update.zip for convenience, although this is not always necessary.
Go to Settings → About Phone and click on MIUI/HyperOS. In the window that opens, click three dots in the corner and select Select a firmware file. The system will prompt you to find the downloaded archive. Once the selection is confirmed, the file will be checked and, if all is correct, the device will reboot to the update mode.
- 📥 Download the correct zip archive for your model.
- 💾 Move the file to the root of internal memory.
- ⚙️ Select the file through the update menu in the settings.
- ⏳ Wait for the installation to be completed and restarted.
If you're trying to install global firmware on top of Chinese without unlocking the bootloader, the system will give you a Can't verify update error. This is the standard behavior of system protection. In this case, you need to use the method with the computer and Fastboot mode, described below. Don't try to bypass this error with modified recovery unless you have deep knowledge.
💡
If the update is interrupted and the phone is frozen, try pressing the power button for 10-15 seconds to force a reboot. If that doesn't work, you'll need to log into Recovery mode via a button combination.
Fastboot and Mi Flash Tool
The most reliable method is to completely re-mark memory partitions and install the new system, and to do this, you need a firmware archive in Fastboot format (extension.tgz), which you need to unpack on your computer. The path to the folder should not contain Cyrillic alphabets or spaces, for example: C:\roms\mi_global.
Launch the Mi Flash Tool on behalf of the administrator and connect the smartphone in Fastboot mode (power buttons are pressed and volume down). Press Refresh button to allow the program to detect the device. In the lower right corner, select firmware mode: Clean all is recommended when changing region to avoid file conflicts.
| Firmware mode | Data retention | Region | Recommendation |
|---|---|---|---|
| Clean all | No (all removed) | Anybody. | Best Choice to Change CN to Global |
| Save user data | Yes. | Just the same region | Update without losing files |
| Clean all and lock | No. | Only the home region. | ⚠️ It could block the phone. |
Once you select the mode, press the Flash button and wait until the process is over. The status bar changes to success, and the phone automatically restarts. The first boot after the firmware can take up to 5-10 minutes, which is normal, since the system optimizes applications. Do not interrupt the process and do not turn off the cable until the desktop is fully loaded.
⚠️ Warning: Never choose Clean all and lock when flashing from Chinese to Global, this will lock the bootloader with incompatible firmware, and the phone will turn into a brick that can only be restored in the service.
Frequent mistakes and ways to solve them
During the firmware process, users often encounter error codes that can scare an inexperienced person. Miss matching image and device error means you are trying to install firmware designed for another smartphone model. Always double-check the device's code name (e.g., ginkgo, ursa, diting) before downloading the file.
If the process hangs on a certain percentage or gives a connection error, try changing the process. USB-port on your computer (use the ports at the back of the system unit), replace the cable or reinstall the drivers. Sometimes antivirus software can block the Mi Flash Tool, so it is recommended to temporarily disable the protection.
- ❌ Mistake. 0x80004005: Access rights or antivirus problem. Launch on behalf of the administrator.
- ❌ Flash Error: Inappropriate firmware file or corrupted archive.
- ❌ Device not found: Drivers or bad cable not installed.
- ❌ Anti-rollback error: Trying to roll back to an older version of the software is prohibited.
The Anti-rollback bug is a big concern, because manufacturers don't allow you to roll back on older versions of Android or MIUI for security reasons. If you try to do that, the device may be locked at the hardware level. Always upgrade to a version with a higher security index.
💡
90% of firmware errors are due to faulty firmware file selection or faulty USB-Careful preparation minimizes the risks.
