The process of changing software on Xiaomi smartphones is often a necessity for users who want to upgrade, change region or return to the device after a failure. The firmware is the foundation on which the entire interface and functionality of the gadget works, so the approach to replacing it requires care and preparation. Unlike a conventional “over the air” update, manual installation of the software gives full control over the Android version and the MIUI or HyperOS shell.
Many owners are wondering how to reflash Xiaomi to get rid of advertising, Chinese software or just get a fresher version of Android before the official release in their region. However, this action comes with certain risks, such as loss of warranty or the possibility of turning a smartphone into a “brick”, which is why it is important to clearly understand the difference between download modes and types of files installed before starting any manipulation.
Preparation of the device and choice of firmware type
Before you start any action, you need to decide on the purpose of the procedure. If you want to just upgrade the phone, you may need to use the standard method through the settings menu. However, if you want to change the region (for example, from Chinese to global) or roll back to an earlier version, you will need to use a computer and specialized software. Recovery and Fastboot are the two main modes in which the process of flashing, and each of them has its own characteristics.
It is important to distinguish between firmware types. The global version (Global) is designed for the international market, has built-in Google services and support for many languages. The Chinese version (China) often comes out earlier, but does not have Russian and pre-installed Google services out of the box. There are also regional versions, such as EEA (Europe) or RU (Russia), which may differ in a set of pre-installed applications.
Make sure to back up all the important data. The flashing process, especially with memory cleanup, will permanently delete all photos, contacts and applications. When switching from Chinese firmware to global unlocking the bootloader is mandatory, while changing the version within one region can go without it. Make sure that the battery is at least 60% so that the device does not turn off at a critical moment.
You will need to download the current system image from the official website or verified resources. Files usually have the extension.zip for Recovery or.tgz for Fastboot. Check the integrity of the downloaded archive, as a corrupted file can lead to installation errors.
Required tools and drivers
To successfully flash a Xiaomi or Redmi smartphone, it is not enough to have a file with the system. A critical element is the correct installation of drivers on the computer. Without them, the PC simply will not see the device in the desired mode. Most often, ADB and Fastboot drivers are required, as well as drivers for a specific processor (Qualcomm or MediaTek).
In addition to drivers, you will need a specialized utility. For the method through Fastboot, the de facto standard is the MiFlash Tool. It allows you to force the system image to be installed without standard checks. For the method through Recovery, an integrated bootloader will suffice, but the firmware file must be renamed to update.zip and placed in the root of internal memory.
Quality. USB-The cable and the port are essential. Use the original cable or quality analogue, which can transmit data, not just charge. Connect your smartphone directly to your computer motherboard, avoiding the use of the device. USB-hubs that may provide unstable power or interrupt the connection.

- 💻 Windows PC or laptop (preferably 10 or 11)

Unlocking the bootloader (Bootloader)
Most serious software manipulations on Xiaomi devices require an unlocked bootloader, a security mechanism that prevents uncertified software from being installed. If you plan to stream your phone over Fastboot or install custom Recovery, this step is mandatory. Without unlocking Bootloader, MiFlash will give you an error when you try to record.
The unlocking process takes time. After applying for the MIUI Unlock Tool on your computer, you often have to wait 7 to 168 hours, and this is done by the company to prevent device theft and malware installation, during which time you can not log out of your Mi Account on your phone.
⚠️ Warning: Unlocking the bootloader results in a complete device data reset (Wipe Data), which can also void warranty in some regions and make the phone more vulnerable to attackers in the event of loss.
To do this, you need to link your Mi Account to the developer settings. Then, while in Fastboot mode, connect your phone to your PC and launch the unlock utility, and once you're done successfully, the phone will restart and all data will be deleted.
What if Mi Unlock says "Couldn't verify device"?
Recovery Flashing Method (without PC)
This is a method that is suitable for updating or changing the system version within one firmware type (e.g. Global to Global) when the bootloader is locked, it is less risky, but has limitations: you can not switch from the Chinese version to the global version and vice versa without unlocking.
First, download the archive and rename it to update.zip. Place the file in the root folder of the smartphone’s internal memory (not in the folder with photos or music, but in the root). Then you need to go to Recovery mode. To do this, turn off the phone and press the combination of the buttons Volume Up + Power before the logo appears.
In the Recovery menu, you can control volume buttons (up/down) and power button confirmation. Select a language (if available), then press Wipe Data and confirm the reset. This will clear the cache and data, which is critical for the new version to work properly.
Once cleaned, go back to the main menu and select Connect with MIAssistant (for some versions) or simply select a firmware file if the menu allows manual selection. In standard mode, often just click three dots in the corner and select Local update, after which the system will find the update.zip file and prompt you to install it.
- 📂 Rename the firmware file strictly in update.zip
- 🗑️ Make sure to run Wipe Data before installation
- 🔋 Make sure your phone doesn’t run out in the process (takes up). 10-20 minute)
☑️ Checklist before firmware
Install firmware via Fastboot and MiFlash
This is the most powerful method for installing any version of software, including region change (China to Global), which requires an unlocked bootloader and computer, the firmware file must be in.tgz format and unpacked into a folder with a short path on the disk (for example, a firmware file must be in.tgz format and unpacked into a folder with a short path on the disk, C:\mi_flash), Avoiding paths with Cyrillic or gaps.
Run XiomiFlash.exe on behalf of the administrator. Press Refresh to let the program see the connected device. The phone should be in Fastboot mode. Connect it with a cable to your PC. The serial number will appear in the list of devices.
In the program, choose the path to the unpacked firmware folder. At the bottom of the window, it is important to choose the correct firmware mode. Usually, clean all (complete cleaning and installation) or clean all and lock (cleaning, installing and locking the bootloader back). Save user data only works if the firmware versions are compatible by type of data encryption.

Possible mistakes and ways to solve them
Even if you follow all the instructions, there can be problems. One of the common mistakes is Error: Miss matching image in MiFlash. This means that you are trying to install firmware that is not intended for this device code, or you forgot to unlock the bootloader. Check the model code (eg, gucci, rosy) and the firmware compliance.
Can't open serial port error indicates driver or port issues. Try reinstalling drivers Qualcomm/ADB, replace USB-Connect the device to another port (preferably) USB 2.0). Sometimes it helps to run a program on behalf of the administrator.
⚠️ Warning: If your phone goes into an endless Bootloop after you have firmware, try doing Wipe Data through Recovery. If that doesn't help, it may be that the firmware version is incompatible with the current bootloader).
There is anti-rollback protection. If you try to install an older version of the software than the one that has the minimum threshold stitched up in the device, the phone may become Hard Brick and stop responding to buttons. Always check the Android version and the protection index before installing.

Save the screenshots. IMEI-In rare cases, when a crash happens, a section with modem data will fly off, and these codes will be needed to recover through engineering utilities.
💡
The most common cause of failure is inattention when choosing a firmware file. Always check the code name of the model (for example, miui_HMNOTE1LTEGlobal) real-world.
