Modern Xiaomi, Redmi and POCO smartphones often come with regional versions of the operating system that may not meet the needs of advanced users. Chinese firmware is devoid of Google services out of the box and contains many localized applications that are useless outside of China. The global version, in turn, sometimes receives updates later or has limited functionality compared to the Chinese counterpart.
The process of changing software gives you access to full control of the device, allowing you to install customized recaps, obtain root rights and use the latest Android features before official releases. However, this action involves risks from loss of warranty to complete failure of the device if the technology is broken. It is critical to understand that unlocking the bootloader automatically resets all data on the device, so creating a backup is a must. In this article, we will discuss all the steps of the process, necessary tools and precautions.
Before you start taking action, you need to understand the difference between firmware types: there is a Recovery ROM that can be installed through a standard update menu, and a Fastboot ROM that requires PC connection and use special utilities. Also firmware is divided into Stable (stable) and Developer (test), Choosing the wrong version can lead to a cyclical reboot or inoperability of individual communication modules.
Preparation of the device and unlocking the loader
The first and most important step is to unlock the bootloader. Without this, installing third-party software is impossible, since the Miui security system blocks the launch of unverified code. First, you need to register your Mi Account account and link it to your phone in the settings menu, and then apply for unlocking through the special Mi Unlock application on your computer.
Waiting process_approval_ may take 3 before 7 As soon as the status changes, you can start to see. It is important to understand that unlocking the bootloader makes the device vulnerable to potential threats if the user does not follow basic digital hygiene rules. It’s also worth noting that some banking apps may stop working or require additional manipulation to run.
To perform the procedure, you will need:
- 📱 Smartphone with a battery charge of at least 60%
- 💻 Computer running Windows with installed drivers ADB
- 🔌 Original. USB-cable
- 🌐 Stable Internet connection for account authorization
⚠️ Warning: Once the bootloader is unlocked, Find the Device will be forced on, and you won't be able to turn it off without completely resetting the settings.
Don't ignore the need to install current drivers. Often, connection problems arise precisely because your computer can't see your phone in Fastboot mode. Make sure the device manager displays the correct name of your gadget without exclamation points. If you use a laptop, it is recommended to connect it directly to the motherboard port, avoiding USB-hub.
Choosing the right firmware version: Global, CN or Custom
The firmware market for the Xiaomi ecosystem is extremely diverse, and it is easy for a beginner to get confused in acronyms. The official versions are divided by regions: Global (world), EEA (Europe), Russia (Russia), India (India) and China (China), each of which has its own characteristics in a set of pre-installed applications and supported communication frequencies. For example, the Chinese version may not support some LTE bands used by European operators.
In addition to the official builds, there are custom firmware such as LineageOS, Pixel Experience or Xiaomi.eu. The latter is a modified Chinese version with cut Chinese software and added Google services. Xiaomi.eu is often considered the middle ground for enthusiasts, as it combines the functionality of the Chinese version with the convenience of the global.
When choosing, you should pay attention to the type of file:
- 📦 Recovery (.zip) – Updates the system without deleting data (usually), installs via the Recovery menu.
- 💾 Fastboot (.tgz) – Complete Flashing with Data Cleanup, Requires PC and Mi Flash Utility.
- 🔧 Recovery (Clean) – Recovery version, but with full memory clearing (Cross-flash).
It is important to remember that models are compatible. The firmware designed for the Redmi Note 10 Pro will not work for the Redmi Note 10, even if the names are similar. Using the wrong file can lead to a "bricking" of the device. Always check the codename of the device, such as sweet for the Note 10 Pro or gauguin for the Note 10 Pro 5G.
What is a codename and where can I find it?
Toolkit: necessary software for flashing
To make a successful software change, you'll need a suite of specialized software. The main tool for Snapdragon and MediaTek-based devices (in Fastboot mode) is the Mi Flash Tool, which allows you to upload system images to your phone's memory, and you can only download it from official resources or trusted forums, since modified versions may contain malicious code.
The second important component is ADB and Fastboot drivers. Without them, the computer will not be able to communicate with the phone in bootloader mode. There is a simplified version of Google's tools that installs everything you need through the command line. Xiaomi ADB/Fastboot Tools may also be required to remove system debris before firmware, although this is not a mandatory step.
Table of major instruments and their purpose:
| Tool. | Appointment | OS | Difficulty |
|---|---|---|---|
| Mi Flash Tool | Firmware through Fastboot | Windows | Medium |
| Mi Unlock | Unlocking the loader | Windows | Low. |
| TWRP Recovery | Installation of custom ZIP-file | Android (on the device) | Tall. |
| ADB Platform Tools | Debugging and transfer of commands | Win/Mac/Linux | Medium |
Don’t forget to prepare a file manager on your phone if you plan to transfer firmware files to internal memory. To work with.tgz archives on your computer, you will need a 7-Zip program or analogue, since a standard Windows archiver may not correctly display the structure of folders of Chinese firmware.
☑️ Firmware readiness check
Fastboot Method: Complete Flashing Through PC
Fastboot is considered the most reliable way to restore or re-grow a device's regionality, allowing you to write all partitions of memory, eliminating file conflicts. First, you need to put your phone in Fastboot mode, usually by pressing the volume button when the device is turned off, and the image of a rabbit repairing an android will appear on the screen.
Connect the device to your computer and launch the Mi Flash Tool. Press the Refresh button so that the program sees your smartphone. If nothing appears in the list, check the Device Manager - the phone should be defined as "Android Bootloader Interface." Next, click "Select" and specify the folder with the unpacked firmware. Important: the path to the folder should not contain Cyrillic characters or spaces.
At the bottom of the program window you will see three options:
- 🧹 Clean all – complete data cleanup and firmware (recommended when changing region).
- 💾 Save user data - firmware with data storage (only possible within one region).
- 🚫 Clean all and lock – Clean, firmware and re-lock bootloader (only for identical regional firmware!).
⚠️ Warning: Clear all and lock is strictly prohibited if you are changing region (e.g. from China to Global) and will result in a Hard Brick device that can only be removed through paid service tools.
Once you select the mode, press Flash. The process will take 200 to 600 seconds. Don't interrupt the connection or touch the cable. If you have a code error, write it down and check the logs in the program folder. Most often, the errors are related to drivers or a corrupted firmware file.
💡
Using Fastboot mode is the only guaranteed way to go from the Chinese version of MIUI to the global one without compatibility errors.
Installation via Recovery and custom TWRP recavers
If you don't need a full data cleanup or want custom build, you can use Recovery mode. Xiaomi's standard recovery menu allows you to install only signed files, so third-party firmware requires the installation of TWRP (Team Win Recovery Project), a modified menu with a graphical interface and advanced functionality.
Installation TWRP It is run through Fastboot mode by the fastboot boot command. twrp.img For a temporary launch or fastboot flash recovery twrp.img For a permanent record, after the transition to TWRP You need to backup the current system (Backup section) and then go to the installation (Install). ZIP-Firmware archive and confirm the swipe.
When installing custom firmware, it often requires cleaning the Dalvik, Cache, System, and Data partitions. This process is called Wipe. Beware: if you don't make Wipe when you switch from one version of Android to another (for example, from Android 11 to 12), the phone can go into an endless reboot cycle. Once installed, it is recommended to immediately flash the Magisk package, if you need root rights, before the first launch of the system.
Frequent problems when installing via Recovery:
- ❌ Error 7 – a discrepancy between the device model and firmware.
- ❌ System UI Stop: conflict between old and new systems (Wipe Data is needed).
- ❌ Bootloop – a damaged firmware file or incompatible kernel.
💡
After the first download of a new firmware, the phone can heat up and run slowly for 1-2 hours. That's normal: the system optimizes applications and indexes files. Don't panic and let the device lie on charge.
Possible mistakes and ways to solve them
Even with strict adherence to the instructions, there can be unexpected situations. One of the most common problems is that the phone does not turn on after the firmware and only the indicator or logo burns. This state is called Bootloop. In most cases, re-routing through the Fastboot with "Clean all" helps. If this does not help, it may be damaged the persist or modem partition, which requires restoration from the engineer's backup.
Another common problem is the broken Widevine L1 certificate, which means Netflix and other streaming services don’t play content in HD. This happens when you flash the global version to a Chinese device (and vice versa) without locking the bootloader back. You can only return the L1 by locking the bootloader with the original firmware, but this is not always possible when changing the region.
Also, users have a "Device is locked" problem when trying to log into Recovery mode after flashing, which is a security mechanism, so to get around it, you need to go to the developer menu and turn on "OEM unlocking" (if available), or reflash the device with a closed bootloader if the region matches. In complex cases, such as losing IMEI, you will need professional hardware to edit NVRAM.
