Modern Xiaomi smartphones often require an operating system update not only for new features, but also to fix critical security vulnerabilities. Users face the need to manually install software when an automatic update freezes or the device gets into a cyclical reboot. Understanding the firmware process allows you to bring the gadget back to life without going to the service center, saving time and money.
The flashing procedure can vary depending on your device model and the region it is intended for. There are several methods, from simple upgrades through the settings menu to complex installation via Fastboot mode using a computer. The choice of the specific path depends on the current state of the system and your goals, whether it is changing the region or recovering from a crash.
In this guide, we will discuss all the preparation steps, necessary tools and step-by-step algorithms of actions. It is important to understand the risks associated with tampering with system files and follow the instructions carefully. A competent approach minimizes the likelihood of turning a smartphone into a brick and ensures the stable operation of MIUI in the future.
Selection of firmware type and preparation of files
The first step is to determine the type of operating system you want. For Xiaomi devices, there are two main archive formats: Recovery and Fastboot. Recovery files have the.zip extension and are designed to be installed directly through the recovery menu or the built-in updater. This is a simpler option, not requiring an unlocked bootloader to install within the same region.
In turn, Fastboot firmware is distributed as.tgz archives and requires a connection to a PC. This method is necessary for deep system recovery, changing the region (for example, from China to Global) or unlocking the bootloader. Fastboot gives full control over memory partitions, allowing you to install the system from scratch, which often solves problems with software errors.
You should download files exclusively from trusted sources, such as the official website miui.com or authoritative forums like 4PDA. Using modified or questionable builds can lead to leakage of personal data or unstable operation of communication modules. Always check the hash amount of the downloaded file, if this is provided by the author of the build.
⚠️ Warning: Installing firmware from another model or region without first unlocking the bootloader is guaranteed to lead to software failure and inability to boot the system.
To make sure that the battery is at least 60 percent, it is also recommended to free up space in internal memory by deleting excess media files or transferring them to your computer. USB-cable or quality analogue is critical for a stable connection to the PC during data transmission.
Required tools and drivers
Before you start active actions, you need to prepare the software environment on the computer. To work with Xiaomi devices in Fastboot mode, you need special ADB and Fastboot drivers. Without them, the computer will not be able to recognize the smartphone in service mode, and the firmware utility simply will not see the connected device.
The official tool for working with Fastboot firmware is the Mi Flash Tool, which allows you to select the data cleanup mode and control the process of writing partitions. ADB/Fastboot Tools, which offers more flexible settings for advanced users, but requires Java installation.
- 📱 Original. USB-cable or certified analogue with data transmission support.
- 💻 Windows PCs (MacOS and Linux drivers may require separate setups).
- 🔓 Mi Account with a linked phone number (required to unlock the bootloader).
- 💾 Backup of all important data, as the process can result in complete deletion of files.
Installation of drivers often occurs automatically when you connect the phone, but in some cases manual intervention is required through Device Manager. QHSUSB_BULK, So the drivers are not installed correctly. In this situation, you should download the Xiaomi package. USB Driver and install it forcefully.
💡
Use it. USB-ports soldered directly on the motherboard (behind the system unit), as the ports of the front panel or USB-Hubs can give unstable tension.
Recovery Update Method (without PC)
This is a good way to boot, but the standard air update doesn't work, so you'll have to manually download a.zip firmware file and put it in the root of the device's internal memory, and it's important that the file isn't renamed and has the right extension, otherwise the system won't see it.
After you download the file, you need to go to the update menu. To do this, open the Service and Feedback app, click on the MIUI version in the upper right corner and select three dots in the menu. Here you need to activate the Select firmware file and indicate the path to the downloaded archive.
| Parameter | Recovery ROM | Fastboot ROM |
|---|---|---|
| File extension | .zip | .tgz |
| PC required | No. | Yes. |
| Unlocking BL | Not always. | I'll be sure. |
| Difficulty | Low. | Tall. |
The system will check the integrity of the file and suggest that the process be started. Once confirmed, the smartphone will restart and start installing. The screen can go out and light up, and the progress bar can hang on certain percentages — this is normal behavior. Interrupting the process at this stage is highly undesirable and can damage the system partition.
⚠️ Note: If after installing firmware in another region (eg Global on China) the phone went into a cyclic reboot, you will need to reset data via the Recovery menu (Wipe Data).
Fastboot and Mi Flash Tool
Fastboot is the most powerful tool in Xiaomi’s arsenal, allowing you to completely rewrite all memory parts, including those that are not available during normal operation of the system. To get started, unpack the downloaded firmware archive.tgz into the root of the C disk so that the path to the folder is short and does not contain Cyrillic.
Launch the Mi Flash Tool on behalf of the administrator. Press the Refresh button and connect the smartphone in Fastboot mode (clamping the volume button when the phone is turned off + connecting the cable). If the drivers are installed correctly, the serial number of the device will appear in the list.
fastboot devicesThis command will help you check the visibility of your device. In Mi Flash, choose the path to the unpacked firmware folder. Below you will see three options: clean all, save user data, and clean all and lock. For a clean installation, choose the first option.
- 🚀 Press the Flash button to start the firmware process.
- ⏳ Expect to be completed, status will change to “flash success».
- 🔄 The phone will automatically restart, the first load can take up to 10 minutes.
☑️ Checklist before Fastboot firmware
It is important not to disconnect the cable until the logo appears. MI If the process is stuck at a certain stage, try changing it. USB-Errors are often associated with poor contact or blocking of the system files of the firmware by antivirus.
Unlocking the bootloader (Unlock Bootloader)
To install global firmware on Chinese versions of devices or custom builds, you need to unlock the bootloader.This is an official procedure from Xiaomi, requiring an account to be linked to the device. After applying in the Mi Unlock Status application, you may need to wait from 3 to 7 days (sometimes up to 30 days).
Once you've been authorized, download the Mi Unlock Tool on your PC. Sign in to the same account you have on your phone. Put your smartphone in Fastboot mode and connect to your computer. Press Unlock and confirm the action. The process will erase all data from the device, so (backup) is mandatory.
What to do if the unblocking status is not updated?
There are nuances with new models that require high levels of activity in the Mi Community community. It is also important to understand that after unlocking, some secure features will stop working, such as payment via Google Pay (NFC) without additional security manipulations (Magisk, Root), and Widevine L1 may disappear, which will reduce the quality of streaming in HD.
Error Resolving and (FAQ)
There can be errors in the firmware process, from "Missmatching image and device" to driver problems. An image mismatch means you're trying to flash firmware from another model. Check the model code at the end of the firmware file name, which should match the code on the box or in Fastboot mode.
If the phone doesn’t turn on after the firmware and only the logo burns, try running Wipe Data through the Recovery menu (clamp Volume Up + Power). In more complex cases, when even Fastboot does not help, you may need to use EDL mode (Emergency Download Mode), which is only available to authorized service centers or through paid accounts.
💡
The most common mistake of beginners is trying to flash China ROM on a Global device without unlocking the bootloop, which leads to bootloop.
The stability of the work after the firmware depends on the quality of the downloaded file and the state of the battery. If the battery is worn out, the surges in the voltage during the recording of sectors can interrupt the process. Always monitor the temperature of the device: if it overheats, pause.
