Owning a Xiaomi device involves regular interaction with the MIUI operating system or the new HyperOS. Periodic updates are not just to change the numbers in the software version, they bring critical security fixes, energy optimization and new interface features. However, the process of installing a new version can cause concern among users who are afraid of losing data or turning a smartphone into a “brick”.
There are several proven upgrade methods, each with its own features and application scenarios. You can rely on an automatic OTA system to report an update, or take control using manual downloading of archives. Manual installation of the full firmware (Recovery ROM) often solves problems with bugs that do not disappear after a conventional air update. Understanding the differences between these methods will allow you to choose the best path for your device.
In this article, we will discuss the algorithms of actions for different situations, we will touch on the issues of preparing a gadget, choosing the right version of software and the direct process of flashing, it is important to follow the sequence of steps to ensure the successful outcome and stable operation of the smartphone in the future.
Preparing the device for system update
Before you start active actions, you need to perform a number of preparatory procedures. Ignoring this step often leads to errors in the installation or loss of user data. First of all, make sure that the battery is at least 60%, and ideally connect the device to the power source. Unstable voltage or discharge at a critical moment can interrupt the process of writing system files.
The second critical step is to back up. Even if you plan to upgrade without a data reset, there is always a risk of software failure. Use the built-in Services app or Google and Xiaomi Cloud services to save contacts, photos and settings. Also free up space in internal memory, as the firmware archive can take up from 3 to 6 GB.
☑️ Checklist before firmware
Be sure to check the stability of the Internet connection if you plan to download files directly. For manual download via your computer, make sure that the USB cable is serviceable and capable of transmitting data, not just charging the device. Using the original cable or a certified analogue reduces the risk of communication failure during file transfer.
Automatic update via OTA (over the air)
The easiest and safest way for most users is to use the built-in OTA (Over-The-Air) mechanism, which independently checks Xiaomi servers for new versions for your model and region, and if an update is found, you will receive a notification, after which you can start the installation process.
However, sometimes it happens that the server already has a new version, but your phone does not see it. This is normal, since updates often come in waves. In this case, you can try to artificially call a check by going to the Settings menu → About the phone → MIUI version and clicking on the system logo. Sometimes it helps to change the region in the settings or clear the cache of the Update application.
💡
If OTA-The update doesn’t come long, try changing the region in the settings (for example, India or Global), check for a new version, and then return the region back to the new version.
The advantage of OTA is that it only updates the modified parts of the system, which saves traffic and time, and it ensures that the version you install is certified for your device and region, and that once you download the archive, the system will offer a reboot, and the process will go through automatically without you.
Manual installation of firmware through Recovery Mode
If the automatic method does not work or you want to install a specific version of the software, the method of manual installation through Recovery Mode is used. To do this, you will need to download the full firmware archive (Recovery ROM) from the official website or proven resources. The file must have the.zip extension and weigh about 4-5 GB.
The downloaded file must be renamed update.zip (if it is a global version) and placed at the root of the device’s internal memory without putting it in folders. Then go to the update menu, click three dots in the corner of the screen and select “Select File” and the system will check the integrity of the archive and, if correct, prompt you to start installing it.
What if Recovery says “Can’t verify update”?
Without unlocking, the security system will not allow you to install foreign code, and if the bootloader is blocked, you can only update within your region.
Firmware through Fastboot with a computer
The most powerful and versatile tool for working with Xiaomi software is the Fastboot mode, which allows you to interact with the device at a low level, bypassing the operating system, a method often used in restoring non-working devices or completely flashing and cleaning all data. You will need a PC, a USB cable and the Mi Flash Tool utility to work.
The process begins with the smartphone switching to Fastboot mode. This is usually done by turning off the device and then pressing the volume button when the cable is connected to the computer. The screen will show an image of a rabbit repairing an android, which signals that the device is ready to receive commands. ADB and Fastboot drivers must be pre-installed on the computer.
In the Mi Flash Tool, you need to specify the path to the unpacked firmware folder. It is important to choose the correct firmware mode in the bottom corner of the window: clean all (complete cleaning), save user data (save data) or clean all and lock (clean and lock the bootloader), the latter option is recommended only if you are flashing the original regional version, otherwise the device may go into eternal boot.
Comparison of Update Methods and Their Features
The choice of firmware method depends on your goals and the current state of the device. Each method has its own technical limitations and advantages. Below is a table that will help you navigate and choose the right option for your situation.
| Parameter | OTA Update | Recovery (Manually) | Fastboot (Mi Flash) |
|---|---|---|---|
| Difficulty | Low. | Medium | Tall. |
| Data retention | Yes. | Yeah (usually) | Depends on the regime. |
| Change of region | Impossible. | Only with an unlocked BL | Possibly (with unlocked BL) |
| Recovery from disruption | No. | Partially. | Yes (full) |
Using Fastboot gives you maximum control, but it requires care. Mistakes in choosing a firmware mode or interruption of the process can lead to serious consequences. OTA method, on the contrary, is as safe as possible from user errors, but is limited by the capabilities that the manufacturer provides for your specific region.
It is also worth mentioning the existence of firmware China, Global and EEA (Europe) - Chinese versions often get updates sooner but may not support some (frequency) communications or Google services out of the box. Global versions are more stable for international use but may come with a delay.
Common mistakes and ways to solve them
During the update process, users are often confronted with the message “Failed to check the update” or “Baget is corrupted.” As mentioned earlier, this is often associated with an attempt to roll back on an older version of Android or MIUI. The protection system prevents downgrade to avoid file system conflicts. The solution is a complete data reset (Wipe Data), but this will delete all files.
⚠️ Warning: If the progress indicator is frozen in one place during the firmware process through Fastboot or if the error text appears red, don't panic. USB And make sure the drivers are installed correctly. Reconnecting the device in Fastboot mode often solves the communication problem.
Another common problem is the bootloop after the update, which can be due to a conflict between the app cache and the new OS version, and then it helps to log in to Recovery mode and execute the Wipe Data command, and if that doesn't help, it's possible that the firmware file was downloaded with errors and its integrity is compromised.
💡
Most update errors are related to memory shortages, an unstable internet, or an attempt to install an incompatible version of software without first cleaning the data.
If you use custom themes or modified system fonts, it is better to return the standard settings before updating. Third-party design elements often conflict with new versions of the shell, causing interface departures or problems with displaying text.
