Xiaomi smartphone owners regularly face the need to update software. System updates are not just a change in numbers in the version number, but a critical process for the safety and stability of the gadget. Manufacturers release patches that close vulnerabilities and optimize the processor for better autonomy.
Many users are afraid to start this process for fear of losing data or turning the device into a brick. However, if you follow the sequence of actions and understand the differences between firmware methods, the risk is minimized. In this article, we will discuss all the available ways to install a new MIUI or HyperOS, from a standard “over the air” update to advanced reflashing through the computer.
A competent approach to the procedure allows not only to get new interface functions, but also to extend the life of the battery. Ignoring updates can lead to incorrect application operation and reduce the overall performance of the system. Before starting any manipulations, be sure to back up important data on an external medium or in the cloud.
Preparation of the smartphone for the update procedure
Before you start the installation process, you have to do a number of preparatory steps, these are basic requirements, ignoring which can lead to interruption of the load or errors in the operation of the communication modules.
Make sure the battery is at least 60 percent charged, or better still 100 percent charged, and the firmware process is energy-intensive, and suddenly turning off the smartphone at a critical moment can damage system partitions, and free up space in internal memory.
To download and unpack the installation package, you may need 3 to 6 GB of free space, depending on the size of the delta between versions.
☑️ Checklist before update
Don't forget to check the stability of the Internet connection. It's best to download large amounts of data over a Wi-Fi network, so as not to exhaust the limits of mobile traffic and avoid connection breaks. If you plan to manually install, download the firmware file to your computer in advance.
Automatic update via settings (OTA)
The easiest and most secure way for the average user is the OTA (Over-The-Air) method, which involves receiving an update directly from the manufacturer's servers, and the system itself checks for a new version and suggests installing it.
To start the process, go to Settings → About Phone. Click on the MIUI or HyperOS logo. If the update is available, a download button will appear. In some regions or on certain versions of the firmware, the path may differ: Settings → Advanced Settings → System Update.
💡
If the update button is inactive, try switching the region of the smartphone in the settings to "India" or "Global", sometimes the servers are updated asynchronously.
Once the file is uploaded, the system will suggest restarting, the screen will go out, and the installation process will begin, which can take 5 to 15 minutes, during which time the smartphone can heat up, which is the normal reaction of the processor to active data recording.
It's important to keep this process going. If the battery goes down or you force the device to restart, you may need to restore it through Recovery mode. Once installed successfully, the phone will turn on with the new version of the interface.
Manual installation of firmware through Recovery Mode
If the automatic update does not come or you want to change the firmware region (for example, from Chinese to global), you use the manual method. You will need to download the archive with the.zip extension from the official website or proven resources.
Copy the firmware file into the root of the smartphone's internal memory. Don't put it in folders, the system should see it right away. Then go to the update menu and press the three dots in the top right corner.
Select Choose update package, the system will find the archive and prompt you to start installing, and if the standard path doesn't work, you can use Recovery mode.
⚠️ Warning: When you manually select a firmware file, make sure it's for your model.Installing firmware from Redmi Note 10 on Redmi Note 11 is guaranteed to bring the device down.
To enter Recovery mode, turn off your phone and press the button combination (usually Volume Up + Power). From the Recovery menu, select the language (English) and Install Update.zip to System One. Confirm the action.
This method allows you to update even if you do not have OTA-It is also useful if the current system is unstable and requires a “clean” reinstallation without loss of user data (assuming version compatibility).
Firmware through your computer with the Mi Flash Tool
For advanced users and cases when the phone does not boot, the Mi Flash Tool is designed. This method requires a Windows PC and drivers. ADB/Fastboot. The firmware in this case has the extension.tgz.
Unpack the firmware archive on your computer. The path to the folder should not contain Cyrillic or spaces. Put your smartphone into Fastboot mode (clamping Volume Down + Power When the device is off) and connect it with a cable to your PC.
fastboot devicesType this command in the command line to make sure the computer sees the device. In the Mi Flash Tool program, select the path to the firmware folder and press Refresh. At the bottom of the window, it is important to choose the correct firmware mode.
| Firmware mode | Description | Impact on data |
|---|---|---|
| Clean All | Complete cleaning and installation | All data is deleted |
| Save User Data | Updating with preservation | Data is retained |
| Clean All and Lock | Cleaning and locking the loader | All data is deleted, BL is blocked. |

After you select the mode, press Flash. It takes 200-400 seconds. When it's finished, the phone automatically restarts. The first run can last up to 10 minutes.
Features of the update from China ROM to Global ROM
Many users buy Chinese-made devices because of their lower cost, but Chinese firmware (China ROM) is devoid of Google services and contains a lot of local software, and the move to Global ROM solves these problems.
The main obstacle is the bootloader lock. To change the firmware region, the bootloader must be unlocked. Official unlocking requires a wait of 7 to 168 hours after submitting an application through the Mi Unlock utility.
Unlocked bootloader: Transition between regions (China) ↔ Global) is not possible by standard methods. Attempting to cross-firm on a locked device will result in an error of signature verification.
⚠️ Warning: Unlocking the bootloader completely erases all data from the device for security purposes. Make sure you sync contacts and photos before starting the procedure.
Once unlocked, you can use the Clean All method in the Mi Flash Tool to install the global version.This will give you full access to Google Play, Netflix in HD, and a multilingual interface.
💡
Switching from China ROM to Global requires the bootloader to be unlocked, which entails complete data loss.
Solving problems and errors in the update
The update process doesn't always go smoothly. Often users experience a "failed to update" error or an endless reboot, and one of the common reasons is version incompatibility.
You can't roll back to an older version of the system without completely cleaning up the data. If you try to install the old firmware on top of the new one, the system will give you an error, and the problem may lie in the damaged firmware file.
Check the checksum (MD5) of the downloaded archive, if the file is downloaded with interruptions, its integrity is violated, download the package from another source or using another browser.
