Many users of Xiaomi devices are faced with the desire to update the operating system to the current version or, conversely, to roll back to a more stable build. The installation process can seem difficult to a beginner, but with strict adherence to algorithms, it becomes accessible even to laypeople. In this article, we will analyze all the nuances of working with MIUI and HyperOS so that you can independently manage the software of your gadget.
Before you start active actions, you need to clearly understand the difference between a simple update and a complete flash. Installing Android on Xiaomi is not just a download of a file, it is a set of measures to prepare the bootloader and the file system. Errors at any stage can lead to the failure of the device, so be patient and carefully study each step.
It is important to realize that modern Xiaomi smartphones have a complex data protection structure, and unlocking the bootloader is a prerequisite for installing custom firmware or global versions on Chinese models, and without this step, any manipulation of system files will be blocked at the kernel level.
Preparation of the device and necessary tools
The first step is always to carefully prepare the workplace and the smartphone itself. You will need a Windows computer, as most of the utilities from Xiaomi are optimized for this platform. Also make sure that the USB cable is serviceable and capable of transmitting data, not just charging the battery.
The device itself must back up all important data. A complete flash reset will inevitably delete all photos, contacts, and applications. It is recommended to use cloud services or transfer files to an external drive to avoid losing valuable information in the process.
- 📱 Charge your smartphone to at least 60% to avoid turning off during the critical phase.
- 💾 Download the drivers. ADB Fastboot for your operating system.
- 🔓 Link your Mi Account and enable developer mode in the settings.
Pay special attention to drivers, without properly installed drivers. USB-The computer will not be able to recognize the phone in bootloader mode, and users often neglect this step, and then wonder why the utility does not see the connected device.
⚠️ Attention: Using an original cable or high-quality analogue with data support is critical. Cheap "charging only" cables can lead to a connection error at the most inopportune time.
💡
Before starting work, take screenshots of all important settings (APN, access points, Wi-Fi parameters) to quickly restore the Internet after the firmware.
Unlocking the bootloader (Bootloader)
The key to installing Android on Xiaomi is the status of the bootloader, which is blocked by the manufacturer by default for security, unlocking Bootloader gives you access to deep system settings, but also removes some of the security mechanisms.
You need to apply in the Xiaomi security app, and after approval (which can take 3 to 7 days), you will receive a notification, and then you can run the official Mi Unlock Tool on your computer.
The unlocking process is triggered by putting the smartphone into Fastboot mode. This usually involves a combination of power and volume buttons, and in this mode, the device waits for commands from the PC, and that's where the lock is removed.

☑️ Checking before unlocking
Selection of firmware type: Global, CN or Custom
Users are often confused about the variety of available software versions. Global firmware (Global) is designed for the international market, has built-in Google services and support for many languages, including Russian.
Chinese versions (CN ROMs) are often released earlier and contain features that may later appear in globals. However, they lack Russian (English and Chinese only) and may have problems with communication frequencies.
Custom firmware is created by independent developers, which allows you to modify the system beyond the capabilities of the manufacturer, remove advertising and add unique features, but the stability of such builds is not guaranteed.
| Type of firmware | Languages | Google services | Stability |
|---|---|---|---|
| Global Stable | All (includes Russian) | There is. | Tall. |
| CN ROM | Chinese, English | I need a setup. | Tall. |
| Custom (AOSP) | Depends on the author. | There is. | Medium |
| Recovery (Beta) | All right. | There is. | Low. |
Regional restrictions may block some NFC applications or features in certain countries, and always check the model’s compatibility with your region before downloading.

Installation methods: Recovery and Fastboot
There are two main ways to install Android on Xiaomi: through the built-in recavator or through the Fastboot mode with the PC. The first method is simpler and safer, the second is more powerful and allows you to solve serious problems.
Installation via Recovery mode is done directly on your smartphone. You download the firmware file (usually with the.zip extension), put it in the root of internal memory and select it from the update menu, the system will check the integrity and install the files.
Fastboot requires a computer connection and a special MiFlash utility, which allows you to completely clear partitions of memory and install a clean system, and is indispensable for the transition between regions (for example, from China to Global).
- 🔄 Recovery: Suitable for updates within a single region.
- 💻 Fastboot: required for region change and complete reset.
- ⚡ Speed: The process usually runs faster and more stable through a PC.
If you choose the Fastboot method, make sure that the path to the firmware folder is Cyrillic-free. The path to the files should be short and simple, for example, C:\Xiaomi\ROM\. This will eliminate error reading utility.
⚠️ Note: When using the Fastboot method with the "Clean All" option, all data will be permanently deleted.
💡
For a normal update, the Recovery method is enough, but for changing the firmware type (CN -> Global), the Fastboot method with full cleaning is mandatory.
Step-by-step instructions for firmware through MiFlash
Let's take a closer look at the PC installation process, because it raises the most questions. First, unpack the downloaded firmware archive. flash_all.bat picture.
Launch MiFlash and connect your phone in Fastboot mode. Press Refresh to detect the device. If it's successful, your gadget's serial number will appear on the list.
In the program interface, select the path to the unpacked firmware folder. In the lower right corner, select the mode of operation. For a clean installation, select Clean All to avoid file conflicts between old and new systems.
flash_all_except_storage.batYou press Flash, you start recording, you run the code and the progress bar on your phone, and you never shut down the cable or interrupt until you see the green "Success" sign.
The first boot after the firmware can take up to 10-15 minutes, and the system is optimized, and you will see the welcome screen, and at this stage the installation is considered complete.
Possible errors and ways to eliminate them
Even if you follow the instructions strictly, you can get into a crash, and one of the most common errors is "Missmatching image and device," which means you're trying to install firmware that's not designed for your model.
Another common problem is the signature verification error, which happens if you try to roll back on an older version of Android or install firmware with a different type of bootloader, in which case only a complete Fastboot cleanup helps.
If your phone is off the bootloop, try re-entering Recovery and resetting to the factory settings (Wipe Data). If that doesn't work, you'll need to flash it again.
- ❌ Mistake 1: Wrong firmware model – check the model code on the back cover.
- ❌ Mistake 2: Damaged USB-cable – replace the cord or port USB.
- ❌ Error 3: Lack of space – Free up internal memory before upgrading.
It is important to understand that software failures are often caused by human factors, and careful file selection and sequencing prevents 90% of all problems.
