How to restore the phone Xiaomi: from resetting settings to flashing

Xiaomi smartphone owners often face situations where the device stops responding to commands, restarts indefinitely or does not turn on at all. This can happen after a failed update, a virus attack or accidental deletion of system files. In most cases, it is early to panic, since system recovery is possible by software methods without contacting the service.

Xiaomi’s modern gadgets are equipped with powerful diagnostic and repair tools that are available even to the average user. However, it is important to clearly understand what kind of failure occurred to choose the right strategy for action. Misguided choice of method can lead to complete data loss or, in rare cases, to a motherboard breakdown.

In this article, we’ll look at all the current ways to reanimate your device, from simple reboots to deep flashing through your computer, and learn how to use the engineer’s hidden menus and special utilities to bring the device back to life.

Diagnostics and primary resuscitation of the system

Before we start taking any drastic measures, we need to assess the scale of the problem, and if the screen is black, but the phone is vibrating or making sounds, maybe the problem is that the MIUI is getting stuck. The first thing you can do is try to do a forced reboot by holding down the power button for 10 to 15 seconds, and it's safe and doesn't delete your files.

If the device is responsive to touch, but is not stable, check for system updates. Often manufacturers release patches that fix critical errors. Go to Settings → About Phone → System Update and check for the availability of the new version of the software. Having a stable Wi-Fi connection is critical here.

⚠️ If the phone heats up to critical temperatures or makes strange clicking sounds, immediately stop trying to turn on and disconnect the charger.

For a deeper diagnosis, you can run a built-in engineering menu that allows you to check the status of the main components: the screen, speakers, sensor and communication modules. To get there, type in the Phone app special code ##6484##. This will help you identify hardware malfunctions that can not be fixed software.

If the software reset didn't work, we're going to go to more serious methods. So if you can save information by connecting to a PC in drive mode, do it in advance. Backup is your best friend when you're manipulating the system.

Resetting settings via Recovery Mode

Recovery Mode is a separate mini computer inside your smartphone that is designed to serve your system, and you can access it even if the operating system is completely damaged, and you need to turn off the device completely, and then you need to press the power and volume buttons simultaneously.

In the Recovery menu, the navigation is done with volume buttons (up/down), and the choice is confirmed by the power button. You will need to find the Wipe Data item. Inside this section, there will be a Wipe All Data option that initiates a complete reset. The process takes from 30 seconds to several minutes.

Once cleaned, the phone will automatically restart. The first run can last longer than usual, up to 10 minutes. Don't worry if the screen stays black for a long time or the "Mi" logo hangs still, this is normal behavior when initializing the file system.

Note that in some regions, the Recovery menu firmware may be in Chinese, so be sure to use the button location: the reset is usually in the second or third item of the main menu, and be careful not to choose Reboot to Bootloader instead of reset if your goal is to clean up the data.

Using the Mi Flash Tool to Flash Up

When software errors are too serious and Recovery doesn't work, Mi Flash Tool comes to the rescue. It's the official tool for installing firmware in Fastboot mode, USB-good quality cable and firmware in.tgz format (not.zip).

The process begins with the smartphone switching to Fastboot mode. To do this, the power button is pressed on the device turned off and the volume decrease is pressed. The image of a rabbit repairing an android will appear on the screen, or the inscription FASTBOOT. After connecting to the PC, the Android Bootloader Interface should appear in the Device Manager.

When you run the Mi Flash Tool, you go to the unpacked firmware folder. In the bottom right corner, it's critically important to select firmware mode. The clean all option will clean your phone completely, save user data will try to save files (it doesn't always work), and clean all and lock will block the bootloader.

⚠️ Warning: Selecting the "Clean all and lock" option when flashing the global version into Chinese (or vice versa) will lead to a "brick" of a device with a verification error.

When you press the Flash button, you start writing data. The progress bar will display status. Under no circumstances, turn off the cable at this point. If the process is stuck at one percent for more than 5 minutes, it may be that the drivers are installed incorrectly or the port is not installed correctly. USB In that case, try another one. USB-port, preferably USB 2.0.

Recovery with Mi Assistant and ADB

For advanced users, there is a Mi Assistant mode available through Recovery, which allows you to connect to your phone via ADB (Android Debug Bridge) and transfer firmware files directly from your computer, which is convenient when you can not use Fastboot or Mi Flash Tool.

To activate this mode, log in to Recovery and select Connect with MIAssistant. On your computer, you must open the command line and enter a command to check the connection: adb devices. If the device is determined, you can start transferring the firmware archive.

adb sideload name file firmware.zip

This command will squander the installation process of the selected file. Unlike Fastboot, the transfer speed can be lower, and the stability of the connection is critically dependent on the quality of the cable. Use the original Xiaomi cables or certified analogues with a conductor thickness of at least 24AWG.

💡

Use the command line on behalf of the administrator to avoid access errors when working with the administrator. ADB-team.

ADB also allows you to delete system applications or make full partition backups, but standard firmware is usually enough to restore functionality, making sure the firmware version of Android matches or is newer than the one before to avoid compatibility issues.

Solving Mi Account and Locking Problems

A common problem after a reset is the Mi Account request, a security mechanism that links the device to the owner's account. If you forget the password, you can only restore access through the official id.mi.com website. Attempts to bypass this protection through third-party services often lead to the phone being inoperable.

In some cases, if the phone was bought with hands, the previous owner might not have untie the device, and the only legal way to unlock the device is to contact the seller to obtain data or provide a purchase check to an authorized service center. IMEI-The device code must match the documentation.

There is also the Unlock Bootloader option, which is required to install custom firmware, which requires you to apply through the Mi Unlock app on your PC and wait 7 to 30 days, and once unlocked, the phone is completely cleaned, which is also a recovery method, but with advanced functionality.

⚠️ Attention! Unlocking the bootloader makes the device more vulnerable to malware and may disrupt some banking applications (Google Pay, Mir Pay.

Common Errors and How to Resolve Them

In the recovery process, users often encounter error codes. For example, an error of -1 in the Mi Flash Tool usually means a problem with the firmware signature or bootloader. A -4 error often indicates insufficient space on the PC drive or an antivirus that blocks file writing.

If the phone goes into an endless bootloop after trying to firmware, try logging in to Recovery and doing Wipe Data again. Sometimes the remnants of old configuration files conflict with the new system, and it also helps to completely drain the battery to 0% and then charge when it is turned off.

💡

90% of download problems are solved by a full reset (Wipe All Data) in Recovery mode, if the physical components were not damaged.

The table below shows the common symptoms and their probable causes:

Remember that mechanical damage, such as moisture or impacts, often causes malfunctions that cannot be fixed programmatically, and in such cases, a diagnosis using a microscope and testers is necessary in a service center.
