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 situations when the device starts to work unstable, unexplained freezes appear or the battery runs out faster than usual, in which case the most effective solution is to return to factory parameters, which allows you to clean up system debris and remove conflicting data.
The memory cleanup procedure, known as Hard Reset, removes all user information, including contacts, photos, installed apps and logins from accounts. It is important to understand that once a transaction is confirmed, it will be technically impossible to restore deleted files without prior backup, which is why it is critical to create a backup of important data to a cloud service or computer before any manipulations begin.
In this article, we will discuss all the existing ways to return the device to its original state. We will look at software methods through the settings menu, reset options through the Recovery Recovery menu, and also touch on the nuances of unlocking your Mi Account. Following these instructions will help you reanimate the gadget and return it to factory speed.
Preparing the device for complete data cleanup
Before you initiate the erasure process, you need to perform a series of preparatory steps that will secure your personal files and ensure the successful completion of the procedure. Ignoring this step can lead to the loss of important information or lock the device security systems. The first step should always be to synchronize the data with the cloud or create a local copy.
Make sure the battery is at least 50-60%.The process of formatting system partitions is energy intensive, and a sudden power outage at this point can damage the file system, turning the phone into a "brick." If the device turns on, connect it to the charger or Wi-Fi network for final synchronization.
☑️ Checklist before reset
Special attention should be paid to the Mi Account account. If you plan to sell the phone or transfer it to another user, be sure to log out of the account through settings. Otherwise, the theft protection will work and the new owner will not be able to activate the device without your password. → Mi Account. → Get out.
Method 1: Reset via the Android settings menu
The safest and easiest method that most users can use is the standard operating system interface, which is suitable for situations where the phone is turned on, the screen responds to touch, and you can freely navigate the menu. The algorithm for actions may vary slightly depending on the version of MIUI, but the overall logic remains the same.
To start, open the main menu and find the Settings icon, usually presented as a gear, in the list that opens, you need to scroll down to About or Advanced Settings. In newer firmware versions, the feature you want is often hidden in the Additional or System section, where you want to select Reset.
- 📱 Click on “Erase all data” or “Reset to factory settings».
- 🔐 The system will request confirmation of the action and possibly enter a pattern lock or PIN-unlock.
- ⏳ Once confirmed, the cleaning process will begin, which can take 5 to 15 minutes.
When you reset, the screen can go out and light up several times, which is normal for the system to do. Don't interrupt the process or try to restart the device manually. When you do, the phone will restart automatically, and you'll see the screen of the initial setting, like when you first turn on after you buy it.

Method 2: Hard Reset with Recovery Menu
If the smartphone doesn't boot, freezes on the logo or the touch screen doesn't respond, the only option is to use Recovery Mode Recovery Mode, which allows you to perform deep formatting even when the operating system is broken.
Turn the device off completely. Then press the volume button and the power button at the same time. Hold them until the Mi logo appears, then release the power button, but continue holding the volume key. In a few seconds, the main Recovery menu will open, which is controlled by volume buttons (up/down), and the choice is confirmed by the power button.
| Action on the menu | Function of the button | Description of the outcome |
|---|---|---|
| Navigation | Volume Up/down | Moving the cursor by menu items |
| Selection of a paragraph | Power button | Confirmation of the selected action |
| Wipe Data | Selection and confirmation | Starting the data cleanup process |
| Reboot | Selection and confirmation | System restart after reset |
From the menu, select Wipe Data, then confirm the selection and press Wipe All Data. The system will require final confirmation, usually Confirm. After completing the cleanup, which will take a few seconds, select Back to Main Menu and then Reboot to restart in normal mode.
💡
If the Recovery menu doesn’t open the first time, try connecting your phone to your computer via the Recovery Menu. USB-cable before buttons are pressed, and on some models, it's a prerequisite for resetting.
Deleting your Mi and Google account before selling
The issue of personal data security when transferring a device to third parties is especially acute. Xiaomi smartphones are equipped with a powerful security system that links the device to the owner’s account. Simply resetting settings through the menu may not be enough if you do not log out correctly from accounts.
The Find Device security mechanism blocks the activation of the phone after a reset, requiring you to enter a password from the last synchronized account. If you forget the password or can not remember the data, the device will become useless for the new owner, so the algorithm of actions in preparation for the sale must be strictly followed.
- ☁️ Go to the settings and select the section "Accounts and synchronization».
- 👤 Select your Mi Account and click “Get Out” by entering the password for confirmation.
- 📧 Repeat the same procedure for your Google account in the sync list.
Only after deleting all accounts can you start the procedure of a complete reset described in the previous sections, which ensures that the device will not remain traces of your digital identity, and the new owner can configure the phone as a new one without unnecessary security issues.
Typical post-reset problems and their solution
After performing the Hard Reset procedure, users may encounter a number of specific situations that are not a breakdown, but represent the standard behavior of the security system. Understanding these nuances will help avoid panic and unnecessary calls to the service center.
One of the most common problems is requesting a Google or Mi Account immediately after turning on, which is FRP (Factory Reset Protection), which works if the reset was not done through the settings menu (for example, through Recovery), but the accounts were not deleted in advance, in which case you need to enter the account data that was last synchronized with the device.
⚠️ Note: If you bought a phone with your hands and when you turn it on, it requires a password from someone else's account, return it to the previous owner. bypassing this protection is illegal and often leads to complete inoperability of the gadget after updating the firmware.
Another common problem is that it takes a long first boot, after a reset, the system takes time to check the file systems and create new configuration files, the initial turn on process can take up to 10-15 minutes, which is much longer than a normal reboot, at which time the logo can hang on the screen still.
If the phone is in a bootloop and can’t boot for more than 20 minutes, the system firmware may be damaged, in which case a simple reset is not enough, and you will need to flash the device through the computer using the Mi Flash Tool utility and official firmware.
💡
Cyclical reboot after reset most often indicates damage to system files or incompatibility of custom Recovery, which requires flashing through the PC.
Data recovery and initial setup
Once the phone has successfully completed all the reset stages and booted, you will see a welcome screen with a choice of language, which marks the beginning of setting up the device from scratch. If you have previously created backups, now is the time to restore them.
When connected to Wi-Fi, the system will offer to restore data from the Mi Cloud or Google Drive cloud, you can choose specific categories to restore: contacts, messages, call log, system settings and a list of installed applications, which will quickly return the phone to normal without manually installing each application.
For users who have made a local backup to a computer or memory card, the import process will look different. Once you set up your main account, go to the Explorer or Mi Cloud app, find the backup file and start the recovery process. It is important that the firmware version when you restore is the same or newer than the version on which the backup was created.
Remember to reconfigure biometric protection. Fingerprints and facial recognition data are stored in the secure memory sector and deleted when reset. Register them again under Settings → Passwords and security to ensure personal data protection.
