How to Reinstall Xiaomi: The Complete Guide

Modern Xiaomi smartphones have a powerful operating system, but even it can eventually fail. Users often face situations when the device starts to work unstable, software errors or virus software that cannot be removed by standard methods, at such moments the only right decision is to completely reinstall the operating system.

The process of restoring factory status can be very different depending on whether the bootloader is locked and which version of the software is installed. Incorrect actions at the initial stage can lead to loss of personal data or, in the worst case, turn the gadget into a brick, so it is extremely important to carefully study the theoretical part before starting practical manipulations.

In this guide, we’ll take a look at all the ways you can reinstall, from simple resets through menus to advanced firmware through your computer. You’ll learn how to prepare your device, what tools you’ll need, and how to avoid critical errors. The safest method for most users is to reset via the settings menu or Recovery without unlocking the bootloader.

Device preparation and backup

Before you start any actions related to reinstallation, you need to perform preparation. Ignoring this stage can lead to irretrievable loss of photos, contacts and correspondence. The system will delete all data from the internal drive when formatting, so creating a backup is a must.

First, check the battery level. To perform a successful operation, the charge must be at least 60-70%. If the device runs out during the process of writing system files, this can disrupt the structure of the memory partitions. Also make sure you remember the password from your Mi Account, since after the reset, the system will definitely request authorization for security purposes.

Use cloud services or local copying to save information. Standard MIUI tools allow you to create a full copy of the system, including applications and their data, this is especially true if you plan to not just clean the phone, but reflash it to another version.

You can use the built-in Xiaomi Cloud or third-party services such as Google Photos to copy. If the amount of data is large, it is advisable to transfer it to a computer or external drive through a computer or external drive. USB-Do not neglect to check the integrity of the saved files before starting the procedure.

Method 1: Reset via the Settings Menu (Soft Reset)

The simplest and safest way to get back to factory settings is right in the operating system interface, and it's a good option for when the phone turns on, the screen responds to touch, and you can get on the menu, and it effectively solves software bugs and slowdowns.

To start the process, go to the settings section. Find the "About Phone" item at the bottom of the list or depending on the shell version. Next, select the "Reset" or "Erase all data" option. The system will warn you that all files will be deleted.

Once confirmed, the device will restart and begin the cleaning process, which can take 5 to 15 minutes depending on the amount of internal memory, and during this process, it is strictly forbidden to remove the battery (if it is not removable) or interrupt the power supply.

💡

If you have two-factor authentication enabled on your Google account, make sure you have access to your phone number or backup codes, otherwise you won’t be able to log in after the reset.

This method is ideal for selling the device or transferring it to another user, as it guarantees the deletion of personal data. However, if the problem lies in the damage to the system files of the recovery partition itself, this method may not help or the process will be interrupted at the initial stage.

Method 2: Recovery Mode (Hard Reset)

If the operating system is not loading or the touch screen is not responding, you need to use Recovery mode. This is a low-level environment that runs independently of the main firmware, and enter this mode with a combination of physical buttons.

Turn off the smartphone completely. Then simultaneously press the volume button and the power button. Hold them until the Mi logo appears, then release the power, but keep the volume up. A menu with a few items in English or Chinese will appear on the screen.

Navigation in the menu is done with volume buttons (up/down), and the choice of item is done with the power button. You need to find Wipe Data or Clear Data. In some versions of Recovery, you first need to select the language (English) and then go to clean.

After selecting a cleanup, the system will ask you to confirm the action, often requiring you to enter a confirmation code or select Confirm. Once the process is complete, select Reboot. The device will restart, and the initial setup will take longer than usual.

Method 3: Complete reinstallation via Fastboot and Mi Flash

For cases where standard methods do not work, or if you want to change the firmware region (for example, from Chinese to global), Fastboot mode is used, USB-The Mi Flash Tool is the most powerful tool in the user's arsenal.

Unlike a reset, it's a full system image record in your phone's memory, and you'll need to download the firmware archive for your model. Importantly, the firmware should be labeled as Fastboot (usually with the.tgz extension) rather than Recovery (.zip).

Put your smartphone in Fastboot mode. To do this, plug the device off to your computer by pressing the volume button. The screen will show an image of a rabbit repairing an android, or the inscription FASTBOOT. Run Mi Flash on your PC, select the folder with the unpacked firmware and press the "Flash" button.

The firmware process takes 200 to 500 seconds. You can't turn off the cable. Once it's done, the phone will automatically restart. The first download can take up to 10 minutes, as the system optimizes applications and creates new partitions.

Possible mistakes and ways to solve them

Even with strict adherence to the instructions, there can be unexpected situations, users often face a signature verification error or inability to log in to their account, and understanding the nature of these errors helps to quickly find a solution.

One common problem is locking the bootloader, and if you try to flash the global version onto a Chinese machine without unlocking it, the program will give you an error, in which case you either need to search for firmware for a specific region or officially unlock the bootloader through the Mi Unlock service, which requires a wait of 168 hours.

Also, there is a “Can’t verify update” error, which indicates that the firmware file is corrupted or that it is not compatible with the model: Always check the checksums of downloaded archives and only use verified sources, such as the official website or authorized forums.

⚠️ Warning: If after firmware the phone goes into an endless restart (bootloop), try to press the power button on the phone. 15-20 If that doesn't work, you'll need to re-rout the data).

In rare cases, you may need to flash through EDL mode (Emergency Download), but this is a service procedure that requires an authorized Mi Account or special equipment.
