Modern Xiaomi smartphones running on MIUI or the new HyperOS require regular updates to maintain high performance and security. Device owners often face delays in the arrival of official packages or want to speed up the process to be the first to try out new features. Proper installation of the latest version of Android allows you to fix bugs, improve the speed of the interface and get the latest security patches.
The upgrade process can vary depending on your gadget’s model, whether it’s a budget Redmi or a flagship Xiaomi series. There are several proven methods, from standard “over the air” updates to more complex manipulations through Recovery mode or computer. The choice of the specific method depends on the current version of the firmware and availability of Internet access.
Before you start any manipulation of system software, it is critical to understand the risks and observe safety precautions. Interrupting the process of writing firmware with a battery charge of less than 30% can lead to complete inoperability of the device. In this article, we will discuss all the steps in detail so that you can correctly update Android on your smartphone.
Preparation of the smartphone to install a new version of the software
Start with a simple but vital battery check: the system will refuse to start the upgrade process if the power level is below a certain threshold, usually 50-60%. Connect the device to the original charger and make sure that the cable is working, as power surges during file writing can be fatal to the motherboard.
The second step is to free up internal memory. Temporary files, app cache, and old photos can take up the gigabytes needed to unpack the installation package, and it is recommended to have at least 5-10 GB free so that the operating system can work correctly in the background during installation.
Remember to back up important data. While regular update methods usually save user files, there is always a risk of failure.Use Google's cloud services or the built-in Mi Cloud tool to save contacts, SMS and app settings.This will take time, but save your data in case of unforeseen circumstances.
☑️ Checklist before update
It is also worth disabling any third-party antivirus or memory cleanup software that may block system processes. If the device has received Root rights or unlocked the bootloader, a standard update may fail or result in a loss of warranty, in which case a more complex approach with full flashing is required.
Automatic updates through system settings
The easiest and safest way to get a new version of Android is to use the built-in OTA (Over-The-Air) mechanism, which does not require a computer connection or special knowledge. The system will contact the server itself, check for an update for your Xiaomi model and offer to download it.
To start the process, go to the settings menu and select About Phone. At the top of the screen, you'll see the current version of MIUI or HyperOS. Click on this plaque to initiate update checks. If the new version is available, a download button will appear.
After downloading a file of several gigabytes, the system will suggest rebooting, the smartphone will turn off, and the brand logo will appear on the screen with a progress indicator, at which time the device cannot be touched, turned off or tried to enter the menu, since the system partitions are recorded.
💡
Use a stable Wi-Fi connection to download, as service packs can weigh more than 3-4 GB and consume mobile traffic quickly.
Sometimes, the new version doesn’t come automatically on an old device, which may be due to regional restrictions or a phased spread of firmware, so you can try changing the region in the settings or using the manual installation method described below.
Manual installation of firmware through the Recovery menu
If the automatic search didn’t work, you can manually update Android by downloading the installation package in advance. You will need a firmware file with the.zip extension, which should exactly match the model of your device, and you can download it from the official website or trusted resources like Xiaomi Firmware Updater.
Copy the downloaded file to the root of the smartphone's internal memory. Don't put it in folders, use the main storage. Then go to the update menu (as in the first method), but instead of checking, click on the three dots in the upper right corner of the screen.
From the menu that opens, select Select a firmware file. The system will find a zip archive and prompt you to start installing. This method often allows you to upgrade to a version that has not yet arrived on the OTA, or roll back to a previous stable build if the new one contains errors.
What if the system says "file cannot be verified"?
This helps to avoid conflicts between the old settings and the new system code.
Update via Fastboot and computer
For advanced users who have experienced serious errors or a device buildup, the method is available via Fastboot, USB-cable and installed driver ADB/Fastboot. It allows you to completely rewrite system partitions, ignoring the state of the current bootloader.
You'll need to download a firmware image with the.tgz extension (for Windows) and unpack it. Then the smartphone is converted to Fastboot mode by pressing the volume button when the device is turned off and connecting to the PC. In the command line, you enter a command to launch the update script.

| Method of updating | Data retention | Difficulty | The need for a PC |
|---|---|---|---|
| OTA (Airway) | Yes. | Low. | No. |
| Recovery (Zip file) | Yes. | Medium | No. |
| Fastboot / MiFlash | No (Full reset) | Tall. | Yes. |
| Recovery (complete reset) | No. | Medium | No. |
💡
Using Fastboot is a “heavy artillery” that solves loading problems, but requires a precise firmware version for a specific region and model.
Solving Mistakes When Updating Xiaomi
The update process is not always smooth. Often users are faced with a message "failed to check the file" or an endless reboot cycle. One of the common reasons is a mismatch in the firmware region. Global version will not stand on top of China without unlocking the bootloader and cleaning it completely.
Another problem is the lack of space. Even if files have been downloaded, the system needs space to decompress them, clear the app cache, delete heavy videos, or transfer files to a memory card if the slot supports internal storage in write mode.
⚠️ Warning: If after the upgrade, the smartphone stopped turning on and only the logo burns, do not panic. Try to press the power and volume button to enter Recovery and select Wipe Data. If this does not help, you will need to flash through Fastboot.
Also consider the status of Xiaomi servers, during peak hours or during the release of major updates (for example, transition from the server to the server). MIUI 14 on HyperOS) servers can be overloaded, in which case it is worth waiting a few hours or trying to change the servers. DNS-servers in Wi-Fi settings.
Sometimes network settings reset or VPN temporarily shutdown helps. Traffic protection can block the connection to update servers, especially if you use free tunneling services with low connection priority.
