Xiaomi smartphones are famous for their functionality and affordable price, but even reliable devices sometimes face software failures. Owners often look for a way to reflash the phone to get rid of advertising in the system, fix errors after a failed update or even bring back to life the device that stopped turning on. The process of replacing the operating system can seem difficult for a beginner, but with a clear algorithm of actions it becomes quite affordable.
There are several methods of software recovery, each of which is suitable for different situations: someone wants to just roll back to a more stable version of MIUI, and someone needs a complete memory cleanup with the replacement of regional firmware for a global one. In this article, we will discuss in detail all the available methods, necessary tools and precautions that will save your device from serious damage.
Before you start any manipulation, it is important to understand that you take responsibility for the state of your gadget. Mistakes can lead to data loss or, in rare cases, locking the device. However, knowledge of the theory and having a good USB cable at hand significantly increase the chances of a successful operation.
Preparation for flashing: necessary tools and actions
Any serious work with software requires the pre-preparation of the workplace and the device itself. The first step is to back up all the important data, because the internal memory will be completely cleaned during the installation of the new system.
You must also make sure that the serviceability is USB-Computer cables and ports. Unstable connections are one of the most common causes of errors in the recording process. Use an original cable or quality analogue that supports data transfer, not just charging. Also check that the battery is charged at least 60% so that the device does not turn off at a critical moment.
⚠️ Note: Before starting the procedure, be sure to turn on debugging by USB In the developer menu if you plan to use advanced recovery methods.
You will need a Windows computer to work, as most official utilities are sharpened for this operating system. PCs must have all the necessary drivers installed, which usually boot automatically when you connect your phone, but it is better to have them on hand in advance.
- 📱 Charged Xiaomi smartphone with unlocked screen.
- 💻 Computer or laptop with Windows operating system.
- 🔌 Original. USB-wire-line.
- ☁️ Backup of important data on external media.
Remember that the quality of the cable directly affects the speed of data transfer and the stability of the process. Cheap wires often do not withstand long loads, which can interrupt the firmware in the middle.
Official method via Recovery Mode (without computer)
The easiest and safest method that doesn't require a computer is to upgrade through the built-in Recovery menu, which is ideal if the phone is on, it's functioning normally, but you need to upgrade or reset to factory settings. To enter recovery mode, you need to turn off the device and press the combination of power and volume buttons.
Once the Mi logo appears, you can release the power button by continuing to hold the volume button until the menu appears. In this interface, you can control volume buttons (up/down) and a power button confirmation. Choose Wipe Data if you want to clean the device completely, or Connect with MIAssistant for more complex operations.
What to do if the menu does not appear?
It is important to note that standard Recovery cannot install custom firmware or change region from China to Global without using a computer, which is primarily designed to reset and install official updates that are already downloaded to memory or available via Wi-Fi.
- 🔄 Select Wipe Data to reset your settings completely.
- 🌐 Use Connect with MIAssistant to communicate with PC.
- 🔙 Press Reboot to reboot in normal mode.
- 🔍 Safe Mode helps diagnose app problems.
If you choose to reset, the system will request confirmation, often requiring you to enter a special code or word that appears on the screen, which is protection against accidental deletion of information that cannot be ignored.
Fastboot and Mi Flash Tool
The most powerful tool for restoring Xiaomi smartphones is the Mi Flash Tool, which works in Fastboot mode. This method allows you to completely rewrite all memory partitions, which effectively solves problems with software errors, bootloops (cyclic reboot) and allows you to change the region of the device. First you need to download and install the utility itself from the official website, and also find the right firmware with the.tgz extension.
Put your smartphone into Fastboot mode by holding down the power button and the volume button on the device turned off. The screen will show an image of a rabbit repairing an android, which signals readiness to work. Connect the phone to your computer and launch the Mi Flash Tool on behalf of the administrator.
☑️ Pre-firmware check
In the program, press the Refresh button to let your computer discover the connected device. Then point the path to the folder with the unpacked firmware. At the bottom of the window, select the firmware mode: Clean all will clear the data completely, Save user data will try to save files (not recommended when changing the region), and Clean all and lock will block the bootloader.
| Firmware mode | Data retention | Locking the loader | Recommendation |
|---|---|---|---|
| Clean all | No. | No. | Standard flashing |
| Save user data | Yes. | No. | Only for updating the version |
| Clean all and lock | No. | Yes. | Back to the store |
| Flash all | No. | No. | Complete cleaning of sections |
After selecting the settings, press Flash and wait for the process to be completed. Success signifies successful completion. If a red error occurs, check the drivers or try another one. USB-port.
💡
Clean all and lock mode returns the device to the “shop-like” state, blocking the bootloader and preventing unauthorized system changes.
Installation of the global version of MIUI on a Chinese smartphone
Owners of devices ordered from China often face the lack of Russian language and Google services, and to fix this, you need to change the Chinese firmware (CN) to global (Global), but there is an important nuance: new Xiaomi models have protection that prohibits direct flashing between different regions without unlocking the bootloader.
If the bootloader is unlocked, the process is similar to the one described above via the Mi Flash Tool. You simply select the global firmware and run the installation in Clean all mode. If the bootloader is blocked, the official utility will give an error Miss matching image and device. In this case, either official unlocking through the Mi Unlock site (requires a wait of 168 hours) or the use of complex workarounds, such as the EDL test mode.
⚠️ Warning: Installing global firmware on a Chinese smartphone with a locked bootloader through third-party methods may result in device locking (Hard Brick).
For users who don’t want to wait a week to unlock, there is an alternative – install custom recoveries such as TWRP. This allows you to install modified versions of firmware, but requires high qualification and removes the warranty. Always check the compatibility of a particular Xiaomi Redmi or Poco model with the selected build.
- 🌏 Global firmware contains Google Services and Russian language.
- 🔓 Unlocking the bootloader is mandatory for changing the region.
- 🚫 Direct flashing. CN Global is not possible without unlocking.
- 🛡️ Use of the TWRP removes the device from the manufacturer's warranty.
It is worth remembering that after the change of the region, some functions associated with geolocation may cease to work, for example, NFC-Payment in some banks or work with the Mi Home app with certain devices.
EDL mode: recovery of the "brick" and deep reset
When a smartphone stops responding to buttons and is not detected in Fastboot mode, Emergency Download (EDL) mode comes to the rescue. This is a low-level mode that allows you to flash the device even when the boot area is completely damaged. Entering EDL often requires disassembling the smartphone and closing special contacts on the board, although some models work with a combination of buttons when connecting to a PC.
To work in this mode, you need not only the Mi Flash utility, but also special authorized Xiaomi accounts or modified versions of programs, since the official service requires authorization. HS-USB QDLoader.
It is important to correctly determine COM-port through which the computer sees the device in mode EDL. In the Device Manager, it will be displayed as QUSB_BULK If the driver is not automatically installed, you need to manually install it, indicating the path to the files.
The firmware process in EDL takes longer as data is recorded sector by sector.Stop power at this point is fatal for the device, so use a full-battery laptop or uninterruptible power source.
- 🔌 Entrance EDL Often requires disassembly of the smartphone body.
- 💻 Qualcomm drivers are needed to determine the device.
- ⏳ The data recording process can take from 5 to 20 minutes.
- 🔒 Official firmware requires an authorized account.
This method is called "heavy artillery" and is used only when other methods of recovery have failed.
Frequent errors and ways to fix them
In the process of flashing, users often encounter error codes that are confusing, one of the most common is Miss matching image and device, which occurs when trying to flash firmware that is not intended for this model, or when trying to change the region without unlocking the bootloader, the solution is one: check the model of the device (for example, the Redmi Note 10 Pro has different versions for India, China and Europe) and the status of the bootloader.
The Can not find the script file error indicates that the firmware path contains Cyrillic characters or spaces. The path to the firmware folder should be short, in English and not contain spaces, for example, C:\mi_flash\rom. Also make sure that the antivirus does not block the Mi Flash utility.
⚠️ Warning: If your phone goes into an endless reboot after firmware, try holding the power button for more than 15 seconds for a forced reboot or log in to Recovery to reset data.
Another problem is the lack of drivers. If your computer can't see your phone, go to Device Manager and see if there's any unknown devices with a yellow exclamation point, and update the drivers by selecting them from the list of devices provided by the system or downloaded from the manufacturer's website.
Sometimes it's a certain percentage of the process. Don't rush to interrupt it right away. If it's more than 10 minutes of progress, check the cable and the port. USB-ports that need to be turned off in Windows power settings.
