☑️ Preparing for reinstallation
Method one: Reset settings via the Recovery menu
The most common way to reinstall the system is to use the built-in mode Recovery. This method is suitable for cases when the smartphone turns on but is unstable, or if you just want to clean it before selling it. This menu is entered by using a combination of physical buttons when the device is turned off.
To get to the menu, simultaneously hold down the power button and the volume up button. Hold them until the logo Miappears, then release the power button, but continue to hold the volume down. The main recovery menu will appear on the screen, where control is carried out with the volume buttons (up/down), and the choice is confirmed with the power button.
You need to find the item Wipe Data and select it. Next, the system will offer two options: Wipe All Data (full reset) and Connect with MIAssistant (recovery mode via PC). Choose the first option for a clean reinstall. The process will take a few minutes, after which the device will automatically reboot.
If after resetting the smartphone asks for the Mi account password that you have forgotten, this is anti-theft protection (FRP). Without entering the correct data, you will not be able to log in.
After completing the procedure, the phone will boot up as new. Vam predstoit proyti pervonachalnuyu nastroyku, podklyuchitsya k Wi-Fi i voyti v svoy Google-akkaunt. This is the safest method that does not require the use of a computer, but it will not help if the system files are already so damaged that the recovery menu does not start.
Method two: Updating through the boot menu (Updater)
If the smartphone is functioning normally, but you want to reinstall the system to eliminate hidden errors or roll back to a more stable version, you can use the built-in application Updater. This method allows you to install a fresh or previous version of the firmware on top of the current one, saving data (if you select the appropriate mode), or perform a clean installation.
First, download the current firmware image in format .zip from the official website or trusted sources. The file must match your device model and region (Global, EU, China). Place the downloaded file in the root of the internal memory or in the folder downloaded_rom.
Go to the phone settings, select About the phone and click on version MIUI or HyperOS several times so that an additional menu appears. Click on the three dots in the corner of the screen and select Select firmware file. Specify the path to the downloaded archive and confirm the action.
| Firmware type | Description | Saving data |
|---|---|---|
| Recovery ROM | Installed via the Recovery or Updater menu | Possible (if you select "Without cleaning") |
| Fastboot ROM | Installed via a PC and the Mi Flash utility | Only with full cleaning |
| Card Update | Updating from an SD card (outdated method) | Depends on the version |
The system will check the integrity of the file and prompt you to reboot for installation. This method is less radical than a hard reset, but is effective for fixing software bugs in the current OS version. If the system offers to update only to a newer version, and you need the old one, this method may not work without additional manipulations.
Method three: Flashing via Fastboot and Mi Flash
The most powerful and universal way to reinstall Android on Xiaomi is to use the mode Fastboot and official utilities Mi Flash Tool on the computer. This method is necessary if the phone does not boot, is stuck on the logo, or if you need to change the firmware region (for example, from Chinese to Global).
To work, you will need a PC with Windows OS, ADB and Fastboot drivers installed, as well as an unzipped folder with the firmware (Fastboot ROM). Connect the switched off smartphone to the computer by holding down the volume down button. An image of a hare in an earflap repairing an android will appear on the screen - this is a sign of successful entry into Fastboot mode.
Run the app Mi Flash as administrator. Press the Refreshbutton for the utility to detect the connected device (its serial number will be displayed). Then click Select and specify the path to the folder with the unpacked firmware. At the bottom of the window, it is important to select the firmware mode.
clean_all - Complete data clearing and reinstallation (recommended)save_user_data - Installing the system while saving data
clean_all_and_lock - Resetting and re-locking the bootloader
After selecting the mode clean_all press the button Flash. The process will take from 200 to 600 seconds. When finished, the smartphone will automatically reboot. The first boot after such a procedure can last up to 10-15 minutes, so do not panic if the screen remains black for a long time.
⚠️ Attention: Unlocking the bootloader is required to flash the global version to Chinese and vice versa. Official unlocking requires waiting from 7 to 168 hours after submitting an application in the Mi Unlock application.
What to do if there is an error in the firmware?
If Mi Flash gives an error (for example, 0x80004005), try a USB port (preferably USB 2.0), reinstall the drivers or use a different cable. Also make sure that the path to the folder with the firmware does not contain Cyrillic characters.
Possible problems and solutions
During the process of reinstalling the system, users often encounter various difficulties. One of the most common problems is a signature verification error when installing firmware via Recovery. This happens if you try to install a version of the OS other than the one currently installed without an unlocked bootloader.
Another common situation is a “bootloop”, when the phone endlessly reboots. If resetting via Recovery does not help, the system partition is most likely damaged. In this case, only flashing via Fastboot with complete data clearing, described in the previous section, will help.
Sometimes after reinstallation, certain functions may not work, for example, VoLTE or cameras. This may be due to incompatibility between the firmware region and the hardware version of the device. Always check that the model code on the box matches the region of the firmware you are installing.
Using an original USB cable and a USB 2.0 port on the computer's motherboard significantly reduces the risk of communication errors when flashing firmware via Fastboot.
If the smartphone is detected in the device manager as "QHSUSB_BULK" or "Qualcomm 9008", this means that the device has gone into deep disaster recovery mode. Exiting this state is only possible through authorized service centers or using special repair boxes, since standard methods are powerless here.
Frequently asked questions (FAQ)
Will my Mi account be deleted after reinstallation?
No, the account is not deleted from the Xiaomi database. After resetting the settings, during the first setup, the phone will require you to enter the login and password for the linked Mi account to confirm the owner’s rights (anti-theft protection). If you forget the password, it will be extremely difficult to unlock the device.
Is it possible to flash the global version on a Chinese smartphone?
Technically this is possible, but it requires unlocking the bootloader. However, if you change your region from China to Global, some features may stop working, such as NFC contactless payment or app notifications. In addition, automatic over-the-air (OTA) updates may stop coming.
How long does the first boot after a reset take?
The first boot after a complete system reinstall (especially via Fastboot) can take from 5 to 20 minutes. At this time, the system optimizes applications and configures partitions. Do not try to manually reboot the phone during this period, as this may damage the file system.
Do you need to remove the SIM card before flashing?
Removing the SIM card is not necessary, but the memory card (MicroSD) can interfere with the process if it has conflicting files. It is recommended to remove the memory card before starting the procedure to avoid recording errors or accidental formatting of the external drive.
