Xiaomi’s smartphones are famous for their functionality, but sometimes software fails that require drastic measures.Flashing the device through a computer is often the only way to bring the gadget back to life after a failed update or infection with a virus. This process allows you to install a clean version of the system without the standard limitations. OTA-update.
Unlike an air update, a PC-based method gives you complete control over partitions of memory, you can roll back to a more stable version of Android, or you can install the latest MIUI or HyperOS build before the official release in your area, but interfering with system files requires careful and clear algorithmic action.
Before you start, you need to understand the risks: incorrect actions can lead to the loss of warranty or turn the phone into a brick. However, with the right approach, the procedure takes no more than 15-20 minutes and does not require deep knowledge of programming, the main thing is to prepare all the necessary tools and carefully read each step of the instructions.
Preparation of equipment and software
The success of the operation depends on 90% of the quality of the workplace. USB-cable (preferably original or certified) and a Windows computer. Using damaged wires often causes a connection to break at a critical time of data recording, which is fatal for the system.
The main tool is the Mi Flash Tool, which serves as an interface between the user and the phone, and it is also necessary to install Qualcomm or MediaTek drivers (depending on the processor) so that the OS correctly identifies the device in boot mode.
⚠️ Warning: Before any manipulations, be sure to back up all important data.The firmware process involves full formatting of internal memory, and it will be impossible to recover photos or afterward contacts.
The official website miui.com or authorized portals like XiaomiFirmware guarantee the integrity of files. The file must have the extension.zip or.tgz and correspond to the exact model of your device, which can be found in the menu "About phone".
Unlock the bootloader and log into Fastboot mode
To install global firmware on the Chinese version or custom builds, you need to unlock Bootloader, a security mechanism that prohibits the launch of unofficial software. The procedure requires obtaining permission from the company through the Mi Unlock application on the PC and linking the account in the smartphone settings.
After obtaining permission (which can take 3 to 7 days), you can switch to activate the mode, to turn off the device completely, and then press the down volume and power buttons simultaneously, and hold them until an image of a hare repairing an android or FASTBOOT is displayed on the screen.
Connect your phone to your computer in this mode. In Windows Device Manager, Android Bootloader Interface should appear in the Android Devices or Xiaomi section. If you display an unknown device with a yellow exclamation mark instead, the drivers are not installed correctly and the procedure cannot continue.
☑️ Firmware readiness check
Selecting the type of firmware: Recovery or Fastboot
Users often confuse the two main types of service packs, although their purpose is radically different. Understanding the difference between them is critical, since the tools used to install them are different. A mistake in choosing can lead to a cyclical reboot or version check error.
Recovery firmware has a.zip extension and is installed via the phone's recovery menu or the regular update menu, it doesn't require an unlocked bootloader and allows you to save user data as long as the region matches. It's a softer update option.
The Fastboot variant comes in the.tgz archive and is designed to be installed exclusively through the PC and Mi Flash utility, which allows you to completely clear all memory partitions, change the region (for example, from China to Global), and fix deep system errors, which is a method we see as the main method for recovery.
| Characteristics | Recovery (.zip) | Fastboot (.tgz) |
|---|---|---|
| Regime required | Recovery / Update menu | Fastboot (Hare) |
| Unlocking BL | Not necessarily. | Required. |
| Data retention | Maybe. | Only with complete purification. |
| Change of region | Forbidden. | Permitted. |

Step-by-step instructions for firmware through Mi Flash
After unpacking the archive with the firmware in the root catalog of the disk (the path should not contain Cyrillic, for example). C:\rom\) You can run the utility. Run the XiaoMiFlash.exe file on behalf of the administrator. In the top menu, click the Refresh button to allow the program to detect the connected device.
If the phone is selected, in the field of the path, specify the folder with the unpacked firmware. The Flash button will become active. Before pressing, it is critical to select the correct firmware mode at the bottom of the window, which determines the fate of your data and the state of the system after the process is completed.
Firmware modes:
Clean all: Complete data cleanup (recommended)
Save user data: save files (possible conflict of regions)
Clean all + lock: Cleaning and re-locking the bootloaderPress Flash and wait for completion. The status bar will change colors: green means ready, orange means recording, red means error. The whole process takes 200 to 600 seconds. Once completed successfully, the phone will automatically reboot and the status will be marked "success."
⚠️ Warning: Never turn off the cable USB And don't turn off your computer while the orange light is burning, and interrupting the boot or system section is guaranteed to bring the device down.
💡
If the process is stuck at 50% or 98% for more than 10 minutes, the port is likely to be a port. USB It doesn't provide enough power. Try connecting to the port. USB 2.0 at the back of the system unit directly, without a hub.
Typical errors and methods of their elimination
Even experienced users face problems. One of the most common mistakes is Missmatching image and device, which occurs when you try to install firmware that is intended for another model, or when the firmware region does not match the current status of the bootloader, the solution is one: check the model and download the correct file.
Flash error or Anti-rollback check failed indicates an attempt to roll back on an older version of Android, which is prohibited by the security mechanism. In this case, you need to look for firmware with a higher version index. Also a common problem is the lack of drivers, which is solved by manual installation through the Device Manager.
Sometimes it just doesn't see the phone, so make sure that the command line shows the serial number when you type fastboot devices. ADB and Fastboot, and try another one. USB-Bad contact is the number one enemy in flashing.
First start and initial setup
After successful firmware, the first start of the system can take up to 10-15 minutes. The screen can go out and light up, the MI or Android logo can be displayed. Don't panic or try to restart the device manually - there is an optimization of applications and creation of system files.
Once you download, you'll see a welcome screen. Select a language, connect to Wi-Fi, and log in to your Google or Mi Account. If you've blocked the bootloader back (clean all + lock mode), the phone may request a password from the account that was before the firmware for security reasons.
💡
After the first download, it is recommended to immediately check the version of the software in the settings and turn off the automatic update if you want to keep the current stable system build.
Restore data from a backup if you did. Check the core modules: the camera, the speakers, the sensor. If everything is working properly, the procedure can be considered successful. Your smartphone now runs on a clean, optimized version of the operating system.
