Modern Xiaomi smartphones, which are based on the MIUI shell or the new HyperOS, are complex computing systems that can accumulate software errors over time. Users often face a situation where the device begins to work unstable, slow down or indefinitely restart after an update. In such cases, a radical but effective solution is a complete return to factory parameters, known as Hard Reset.
Memory and settings cleanup requires care, as it permanently deletes all user information. Before any manipulations, you need to clearly understand the difference between a simple reset via the menu and deep recovery through Recovery Mode. Wrong actions can lead to the loss of important contacts, photos and accounts, so preparation plays a critical role in the success of the operation.
In this guide, we will take a look at all the available methods for returning a device to its original state. We will look at standard methods through the system interface, the use of engineering menus and emergency methods for locked devices. We will focus on the nuances of working with a Google account and Mi Account, which often become an obstacle for inexperienced users.
Preparing the device for a complete data reset
The first and most important step is to back up all valuable information. Once activated, the system will delete all photos, videos, music, downloaded documents and application databases. Xiaomi's built-in tools allow you to create a backup for internal memory or the cloud, but for maximum reliability, it is better to copy the data to a computer or external drive.
Be sure to check the battery level. The process of formatting the system partition and reinstalling components can take 10 to 30 minutes, and a sudden power outage at this point can damage the bootloader. If the battery is weak, plug in the original charger and leave it connected for the duration of the procedure.
⚠️ Warning: Make sure you remember the password from your Google account and Mi Account. Once reset, the system will require authorization from these services to confirm ownership of the device (protection) FRP). Without this data, the phone will become a brick».
Remember to turn off Find Device in your security settings if you plan to transfer your smartphone to another owner, which untie the device from your digital profile and prevents the new user from blocking. SIM-MicroSD card and memory card so you don’t accidentally format external media unless you plan to clean them.
☑️ Checklist before reset
Reset via the standard settings menu
The safest and easiest way to return to factory settings is available directly from a working operating system, which is suitable for most situations when the smartphone is turned on, the screen responds to touch, and the interface does not hang dead. The algorithm of actions may vary slightly depending on the version of MIUI, but the general logic remains the same for all models, whether it is a budget Redmi or flagship Xiaomi.
To start, open the Settings app and scroll down to the bottom. You're interested in the About Phone section, which usually contains information about the system version and processor. Inside this menu, you'll find the Settings Reset or Advanced Settings item, where the Delete button hides, and the system will alert you to the consequences and ask you to enter the unlock code.
In some versions of the firmware, the path may look different: Settings → About Phone → Settings → Reset → Erase all data. Once confirmed, the phone will restart and the cleaning process will begin. Don’t be afraid if the screen goes out or the Android logo with a progress bar appears – this is the normal operation of the system.
What to do if the reset button is inactive?
It is important to note that this method does not affect the files on the memory card if it is installed, but it is better to be safe and remove it in advance. Once the procedure is completed, the smartphone will turn on as a new one, offering to choose a language and connect to Wi-Fi. All system applications will return to the state “out of the box”, and the user’s software will be removed completely.
Using Recovery Mode for Resetting
If the operating system does not load, freezes on the logo or the touch screen has stopped responding, the only way out is to use Recovery mode. This is a special diagnostic interface recorded in the device memory regardless of the main firmware, logged in with a combination of physical buttons, which allows you to control the phone even when the display is not working (by ear or vibration, although in Recovery the screen usually works).
To get into the recovery menu, turn off your smartphone completely. Then simultaneously press the volume button and the power button. Hold them until the Mi logo appears, then release the power, continuing to hold the volume until the main Recovery menu appears. Navigation is done with volume buttons (up and down), and the choice of item is confirmed by the power button.
In the list that opens, select a language (if available) or go straight to Wipe Data. The system can request confirmation by offering to select Wipe All Data. After confirmation, the formatting process will begin. Unlike resetting via menus, this method is more “rough” and guarantees to clear all partitions, including cache and temporary files that may have caused errors.
| Action. | Navigation buttons | Confirmation button | The result |
|---|---|---|---|
| Entrance to Recovery | Volume + and Nutrition | Retention | Launching the diagnostic menu |
| Choice of menu item | Volume Up/down | - | Moving the cursor |
| Confirmation of choice | - | Meals (short) | Execution of the team |
| Reboot System | Loudness | Nutrition | Reboot to Android |
Once the cleanup is completed, you need to select Reboot and then Reboot to System, and the phone will go into a reboot that lasts for the first time longer than usual, up to 5-7 minutes, which is normal, as the system creates new configuration files and checks the integrity of partitions.
Reset via service menu and special codes
There is a lesser known but effective way to initiate a reset via an engineering menu or specialty. USSD-The team, although in modern versions MIUI However, for some older models or regions, this method can be a salvation when other options are not available.
One option is to use the ##7780### code in the Phone app, which commands to trigger a reset menu similar to the one in the settings, but if the system blocks the character set or does not respond to the command, it means that the manufacturer has limited this functionality, in which case you should rely only on physical buttons or settings menu.
There is also the possibility of using Fastboot mode for flashing, but this is a more complex procedure that requires a computer, cable. USB and the installed driver ADB/Fastboot. The fastboot erase userdata command completely clears the user partition, which is considered an expert method and is used more often in service centers or when flashing the device to the global version.
⚠️ Note: Using Fastboot commands and engineering codes without proper experience can lead to complete data loss without the possibility of recovery.
For ordinary users who don't want to mess with the command line, the best solution is to use standard system tools. Engineering methods are good for their versatility, but the risk of error when entering parameters is high. If you are not sure about your actions, you should use the proven method through Recovery.
Solving Google Account and FRP Problems
One of the main security mechanics of Android is FRP (Factory Reset Protection), which is designed to ensure that the stolen phone can not be used after a reset. If you performed Hard Reset, but previously entered a Google account on the device, the system will require the username and password of this account when you first activate.
This requirement will not be ignored, the phone will remain locked on the welcome screen. If you forget your password, you need to restore it through the Google site on another device. Please note that after resetting your password, you may need to wait 1 to 24 hours before trying to log in on your phone, which is an additional security measure.
The same thing happens with Mi Account, where if Find Device was active, you'll need to enter a password from your Xiaomi account after reset, and without that, it's almost impossible to unlock your device legally, so you'll need to log out of all accounts before you sell or transfer your phone.
💡
Tip: If you buy a used Xiaomi phone, ask the seller to reset your settings and log out of your accounts, ensuring that the device is not blocked by FRP after the reboot.
What to do if the phone does not load after resetting
In rare cases, after the reset procedure is completed, the smartphone may get stuck in a bootloop cycle or freeze on the logo. This may indicate damage to system files during the formatting process or a conflict of residual data. First of all, try to perform a forced reboot by holding the power button for 10-15 seconds.
If a simple reboot doesn't work, you need to re-enter Recovery mode and try resetting. Sometimes a single procedure doesn't clean all partitions correctly. If a reset doesn't work, then the problem is probably the firmware itself is damaged, and you'll need to completely reflash it through your computer using the Mi Flash Tool.
Also, hardware malfunctions can be the cause, such as memory wear or button problems that may have been accidentally pinched while on. If the device is showing signs of life (vibration, sound) but the screen remains black, try connecting it to the computer - if the PC responds to the connection, the chance of saving data or reflashing the phone remains high.
