How to reinstall Xiaomi: from resetting settings to flashing

Xiaomi smartphones that run on MIUI shells or the new HyperOS are famous for their functionality, but over time, even powerful hardware can encounter software errors. Accumulation of system debris, conflicts after unsuccessful updates or malware infection often lead to the device starting to work unstable.

The system recovery process can range from simply resetting through the settings menu to complex flashing through Fastboot mode using a computer. The choice of the specific method depends on whether the phone is turned on at all, whether you have access to the desktop and how deeply the operating system is damaged. Complete system reinstallation always involves permanently deleting all user data, so creating a backup is a must.

In this guide, we will take a look at all the available ways to reinstall software, from standard tools to advanced methods for experienced users. You will learn how to properly prepare the device, where to download official firmware images and what actions to take if the process went wrong. A competent approach to the procedure will extend the life of your smartphone without having to visit the service center.

Preparation of the smartphone for the recovery procedure

Before you start any manipulation of system files, you need to conduct thorough preparation. Ignoring this stage can lead to the loss of important contacts, photos or even turn the smartphone into a “brick”. First of all, make sure that the battery charge is at least 60%, as the process of writing data is energy intensive and power interruption is critical.

The second important step is to create a full backup, and the MIUI shell has a built-in tool to do this, which allows you to save not only media files, but also folder structure, call logs and messages, and sync important data with your Google account or Mi Cloud service, so that in the event of a failure, you have a restore point.

• 📱 Charge the device to at least 70% to ensure the process is complete.
• 💾 Copy photos and documents to your computer or cloud storage.
• 🔐 Remember or write down the password from your Mi and Google account, as after the reset, the system will require them to confirm the owner (protection) FRP).
• 📶 Prepare quality. USB-cable, preferably original if you plan to work with a PC.

It is also recommended to free up space on internal memory if you plan to download firmware directly to your phone. To work with your computer, make sure that it has the current ADB and Fastboot drivers installed, as well as the Mi Flash Tool utility for advanced installation methods.

Complete Reset Method through System Settings

The easiest and safest way to reinstall Xiaomi is right from the smartphone menu if it functions normally.This method, known as Hard Reset through the interface, returns all system settings to factory values and removes custom applications.It is ideal for selling the device or eliminating software glitches that do not affect the bootloader.

To perform the operation, go to Settings → About Phone → Reset. Here you will be asked to select the option “Erase all data”. The system will warn you several times about the consequences and ask for a graphical key or PIN unlock the screen to confirm the actions.

⚠️ Warning: If the phone has two-factor authorization enabled or specific security settings, the device may lock in the initial setup stage after reset.

It is important to understand the difference between normal file deletion and full formatting. Some versions of MIUI include the option “Format internal memory”, which makes data recovery impossible even with specialized software, this is the most reliable option before transferring the gadget to a new owner.

💡

Before performing reset via settings, remove SIM-microSD card and memory card so that external media are not accidentally formatted along with the phone’s internal memory.

Using Recovery Mode for Clean Installation

If the operating system is not loading or operating with critical errors, you need to use Recovery Mode. This is a special partition of memory that starts independently of the main OS and allows you to perform low-level operations.

To get into the Recovery menu, press the Volume Up and Power buttons at the same time. Hold them until the Mi logo appears, then release the Power button, keep the volume up. In the menu that appears, the navigation is done with the Volume buttons, and the choice is with the Power button. You need to find the Wipe Data item.

Within this section, select the Wipe All Data option and confirm the action. The system can request confirmation via the Mi Account if the Find Device function was active. This method clears the data and cache partitions, but does not affect the system partition, which allows you to correct errors caused by the conflict of user settings.

There is also a Clean All mode that formats internal memory completely, unlike simple Wipe.Use it only in extreme cases when other methods don't help, as it's tantamount to completely reinstalling the system from scratch.

Fastboot flashing via computer

For cases where you want to change the firmware region (for example, from Chinese to global) or restore the system after a serious failure, Fastboot mode is used. This method requires a computer, installed drivers and a firmware file in.tgz format. This is the most powerful tool in the user's arsenal.

First, you need to download the official firmware for your model from the site miui.com or proven resources. Note that the Fastboot method requires the Fastboot ROM archive, not Recovery. Unpack the archive in the root of the C disk so that the path to the files is short and does not contain Cyrillic.

Then, put your smartphone into Fastboot mode by pressing Volume Down and Power. The screen will show an image of a hare in a hat-eared android repair. Connect your phone to your PC and launch the Mi Flash Tool utility. Press the Refresh button to find the device, then select the path to the firmware folder.

At the bottom of the Mi Flash window, select clean all mode for guaranteed clean installation. Avoid lock option unless you are 100% sure the firmware matches the device region, as this can lead to boot boot lock and boot inability. Press the Flash button and wait for the process to complete, which usually takes 200-500 seconds.

Solving Common Errors in Reinstallation

The reinstallation process is not always smooth, and users may encounter various errors. One of the most common problems is the Missmatching image and device error in the Mi Flash Tool. It occurs when trying to install firmware from another model or region on a locked bootloader. The solution is one: use a strictly appropriate firmware model.

Another common problem is the Mi logo hanging after a Bootloop, which may indicate damage to system files or a hardware malfunction of the power button that is constantly pinched. In the event of a software failure, reflashing in Fastboot mode with the Clean All option helps.

⚠️ WARNING: If the phone goes into an endless reboot immediately after connecting to a charge or computer, it may be the charging plume or battery itself that is the problem, not the software.

Users are also often required to unlock the Unlock Bootloader, which is not usually required for global firmware versions, but when trying to reflash the Chinese version to the global version without unlocking, the process will end in error.

💡

Most firmware errors occur due to a mismatch in the version of the phone model software or the use of poor quality software. USB-cable interrupting the connection.
