The process of software updates on Xiaomi smartphones is often a necessary step to get new features, fix security bugs, or even restore the device to health after a failure. Users who download a firmware file often face a dilemma: which method to choose and how not to turn a modern gadget into a useless “brick.” There are several proven installation methods, each of which has its own characteristics, preparation requirements and risks.
Before you start taking action, you need to clearly understand what exactly you downloaded. Files can have the.zip extension to update through Recovery mode or be.tgz archives designed to be firmware through your computer in Fastboot mode. Wrong method choice for a particular file type can lead to a cyclical reboot or complete system failure. In this article, we will discuss in detail all stages of preparation and direct installation to minimize risks and ensure a successful result.
It is important to realize that tampering with system files is always a risk, although Xiaomi provides official tools, human factors and technical nuances (e.g., bad ones). USB-cable or power interruption can be a cruel joke, so it is critical to read each step of the instructions carefully and not miss preparatory procedures, such as creating a backup of data.
Preparatory stage and compatibility check
The first and most important step is to verify the downloaded file. The firmware must be strictly consistent with the model of your device. Using a file from another model, even if it looks identical, can lead to permanent damage to the hardware, such as failure of the communication module or touch screen. Check the model in the Settings → About phone section, which shows the exact code of the device, for example, Redmi Note 10 Pro (sweet).
Next, you need to verify the integrity of the firmware file itself. If the download was interrupted or the file was damaged while writing to disk, the installation will not begin or end in error. It is recommended to check the checksum (MD5 or SHA1) of the downloaded file with the one listed on the official website or developer forum. To verify the integrity, you can use special ulites on the PC or built-in functions of file managers.
⚠️ Warning: Before you start any manipulation, be sure to back up all important data (contacts, photos, documents) to an external medium or to the cloud.
You also need to prepare the smartphone itself. The battery should be at least 60% charged, and ideally be fully charged. During the recording of system partitions, the energy consumption can be unstable, and suddenly turning off the device at this point is fraught with serious consequences. Free up internal memory: for the correct operation of the update mechanism through Recovery, it is desirable to have at least 5-10 GB of free space, even if the weight of the firmware file is smaller.
Recovery (Local Update)
The safest and easiest way to install the downloaded firmware is to use the built-in Recovery mode, often called the “Local Update” – a method that does not require a computer or special drivers, all actions are performed directly on the smartphone screen. However, it is worth remembering that this method only works to upgrade to a newer version of MIUI or to reinstall the same version, but not to roll back to an older one.
To activate the hidden local update feature, you need to enable additional features in the Update app. Go to the menu, click on the three dots in the upper right corner and select Select a firmware file. If there is no such option, you need to quickly click on the current version of MIUI (logo or build number) several times until a pop-up message about activating additional functions appears.
Once activated, the action algorithm becomes linear and clear. The system will check the file for compatibility and, if all parameters are normal, prompt you to start the process. During installation, the screen can go out and light up, and the device will be rebooted several times - this is the standard behavior, indicating that new system partitions are written.
☑️ Checklist for Recovery Mode
There are nuances when choosing the type of archive. This method is only suitable for the.zip archive, which is often marked as "Recovery ROM." If you downloaded the.tgz archive, this method will not work for you, and you will have to unpack it or use the computer. It is also important that the firmware region matches the region of the device (for example, you can not just put the Global ROM on a device with a Chinese bootloader without unlocking).
Instructions: Install firmware through Recovery
Let’s take a look at the step-by-step algorithm for installing the downloaded ZIP-First, move the firmware file to the root directory of the smartphone's internal memory without putting it in folders to make it easier for the system to find it, update.zip, although modern versions MIUI They can also recognize long file names.
Then open the Update app and follow the instructions. Once you select the file, the system will check. If the firmware version is newer than the current one, the Update button will appear. If you are trying to install the same version or older, the system may warn you of risks, and you will need to continue by pressing the menu button and selecting Reboot to Recovery or simply confirm the action.
What if you have a “Can’t verify update” error?
Once confirmed, the installation process will begin, which can take 5 to 15 minutes depending on the amount of updates and memory speed of the device, during which time the phone will be unavailable. Upon completion of the process, the device will automatically restart to the updated system. The first run can last longer than usual - this is the normal optimization of applications and system libraries.
| Parameter | Recovery ROM (.zip) | Fastboot ROM (.tgz) |
|---|---|---|
| PC required | No. | Yes. |
| Data retention | Partially (depending on version) | Clean-up only (Clean) |
| Difficulty | Low. | Tall. |
| Possibility of rollback | No (no reset) | Yeah (unlocked) |
Firmware through Fastboot with a computer
Fastboot is the most powerful tool in the Xiaomi user’s arsenal, allowing not only to update the system, but also to restore the device after serious failures, change the firmware region (for example, from China to Global), and even unlock the bootloader. This method requires a Windows computer, original or high-quality. USB-cable and downloaded firmware archive in.tgz format.
The first step after unpacking the archive on the computer is to convert the smartphone to Fastboot mode. To do this, the phone turned off must be pressed simultaneously with the volume button and the power button. The screen should appear a hare in an orange cap fixing an android, and the inscription FASTBOOT. After connecting to the PC in the Device Manager, the device must be defined as Android Bootloader Interface.
⚠️ Note: Using the Clear All command when you are running through Fastboot without an unlocked bootloader on some models may result in the device being locked by your Mi Account.
For direct firmware, the official Mi Flash Tool is used. Launch the program on behalf of the administrator, click the "Select" button and specify the folder with the unpacked firmware (it is important to choose the folder where the file lies). flash_all.bat, In the lower right corner, select firmware mode: Clear All (complete clean) or Save User Data (data storage, not always working).
After selecting the mode, press the Flash button, which will take 200 to 600 seconds, interruption of this process is strictly prohibited, since at this point, low-level memory partitions are recorded, successful completion will be indicated by the green bar in the State column and the status of success.
💡
Fastboot mode allows you to change the region of the device and restore the system even in case of serious software errors, but requires drivers and the Mi Flash utility on the PC.
Solving Common Errors in Installation
Even if you follow all the instructions, you can get errors, and one of the most common is Error 7 or Status 7 when you install it through Recovery, which means that the updater script inside the archive checks the device model that doesn't match yours, and you can do this by opening the archive (without unpacking it completely), finding the META-INF folder, deleting the contents of the com.google.android folder, and packing it back.
Another common problem is hanging on the MI logo (Bootloop). If after installing the firmware, the phone restarts endlessly, try entering Recovery mode (pressing the power and volume button) and performing a factory reset (Wipe Data). If that doesn't help, it may be that the firmware file was broken or not suitable for your hardware revision.
And people often complain that the computer can't see the phone in Fastboot mode, and 90 percent of the time, the problem is the cable. USB They support data transmission, many are just for charging. Try replacing the cable, use another cable. USB-port (preferably) USB 2.0 on the back of the system unit) or reinstall Xiaomi drivers USB Driver.
- 📱 Signature verification error: occurs when you try to install the official firmware on a device with the unlocked bootloader, if the regions do not match.
- 🔋 Sudden shutdown: If your phone is turned off while you're running the firmware, try logging in to Fastboot again and starting the process again.
- 💾 Memory Lack: Before installing, make sure that the free space exceeds the size of the firmware file at least in the amount of time. 2-3 time-file.
Actions after successful firmware installation
Once the new system has booted, don't rush to install all the apps right away. Give the phone 10-15 minutes to work in the background: the system will complete database optimization, update indexes and adjust energy saving, during which time the device may get slightly warmer - this is a normal process of the processor.
Be sure to check the basic functions: sensor, microphone, speakers, Wi-Fi and Bluetooth. If you have changed the firmware region (for example, from China to Global), make sure that notifications from messengers work, since Chinese firmware aggressively works energy saving, killing background processes. It is also worth checking for security updates, since the downloaded firmware may not be the freshest at the time of download.
💡
After flashing, it is recommended to calibrate the battery: discharge the phone before turning off, then charge to 100% when turned off, which will help the system correctly display the percentage of charge.
It's better to restore data from a backup selectively, so you don't have to restore system settings and applications of the old system "wholesale", because this can transfer old conflicts and errors to a new clean system, you better set the phone as new, installing applications as needed.
