How to Clean Xiaomi Phone to Factory Settings: The Complete Guide

Xiaomi’s current smartphones, including the popular Redmi and POCO lineups, accumulate a huge amount of temporary files and system debris during active use, which over time leads to slowdowns, application errors and reduced device autonomy. A complete reset is a radical, but often the only effective way to return the gadget to its original speed and stability.

Cleaning procedures may be required not only to speed up work, but also when selling a device so that new owners do not have access to your personal data. Also, a reset is often used to unlock access to the system if the pattern lock or password from the account has been forgotten. It is important to understand that Hard Reset will completely destroy all user information, so pre-preparation is critical.

In this article, we will discuss in detail all available methods of returning the system to the original state, you will learn how to properly prepare the Android device, what are the nuances of resetting through the settings menu and how to act if the smartphone stopped booting. Following the instructions will avoid common errors and preserve the integrity of system partitions.

Preparing the device for a complete data reset

Before taking decisive action, there are a number of mandatory preparatory steps that need to be taken: ignoring these recommendations can lead to the loss of important contacts, photos and access to banking applications. Backup is the first and most important step that should not be missed under any circumstances.

Make sure the battery is at least 50-60%, the process of formatting the data partition is energy intensive, and suddenly turning off the smartphone in the middle of the procedure can lead to damage to the bootloader or critical errors of the file system.

⚠️ Warning: If you plan to sell your phone or transfer it to another person, make sure to log out of your Google and Mi Account. FRP, The new owner will not be able to activate the device without your passwords.

You can use built-in MIUI tools or cloud services to save data. Go to your phone's settings and find the About Phone section, then Backup and Restore, where you can create a full copy of the system to an SD card or internal storage (if you plan to transfer to another phone).

Reset via the MIUI settings menu

The safest and easiest cleaning method is available directly from a working operating system, which is suitable for most users who want to simply refresh or prepare a smartphone for sale. The MIUI and HyperOS interface has a built-in feature that will automatically perform all the necessary actions.

To start, open the Settings app and scroll to the bottom of the list. Find About and click on it. In the menu that opens, select Reset option. The system will offer two options: Reset all settings (without deleting files) and Erase all data (full reset).

Once you select "Erase All Data," the system will request proof of identity, you will need to enter a screen unlock password or a pattern lock. If the device has two-factor protection or Mi Account binding enabled, you may need to enter a password from the account, a protective measure to prevent malicious users from deleting data.

In some versions of firmware, especially in Chinese builds, the process may be slightly different, where you first need to click on three dots in the top corner of the screen and select "Reset settings", then the system will check for critical errors. If the check is successful, click "Next" and confirm the action with the "Clear All" button.

💡

Before starting the reset process, close all applications that are running, which will help the system to complete the background processes faster and start formatting without delay.

Hard Reset via Recovery Mode

If the smartphone is stuck, not turned on or locked, standard login to settings becomes impossible. In such cases, Recovery Mode is used. This method allows you to clean at a deeper level, bypassing the operating system. It is also known as hard reset.

To enter this mode, you need to turn the device off completely. Then simultaneously press the volume button and the power button. Hold them until the Mi or Redmi logo appears on the screen, after which the power button can be released, continuing to hold the volume. In a few seconds, the main Recovery menu opens.

Navigation in this menu is done with volume buttons (up/down), and the choice is confirmed by the power button. However, modern versions of Recovery often support touchscreen control. You need to select the language (usually available in English and Chinese), and then go to the item "Wipe Data".

In the next menu, select the option "Wipe All Data" and confirm the action by clicking "Confirm". The system will warn that all data will be deleted. After the process is completed, which can take several minutes, select "Back to Main Menu" and then "Reboot".

⚠️ Note: When reset via Recovery Mode, antivirus protection FRP (Factory Reset Protection) remains active. Once enabled, you will be required to enter a Google account that was synced to the device before the reset.

There is also a Fastboot mode, which is often confused with Recovery, which you can log in by pressing the volume and power button. However, through Fastboot, a regular user can not reset without connecting to a computer and using special utilities like Mi Flash Tool. For simple data cleaning, use Recovery.

Deletion of accounts and protection of FRP

One of the main problems after a reset is blocking Google FRP. The security mechanism binds the device to the owner's account. If you performed a reset but forgot to delete the account in advance, the system will require you to enter the login and password from the last synchronized Google account when you first set up.

The same is true of Mi Account, where the Xiaomi ecosystem is very aggressive in its anti-theft protection, and without deleting your account before you reset or knowing your password, unlocking your phone will be extremely difficult, and in some cases impossible, without going to the service center with your purchase checks.

To avoid these problems, follow the following steps before resetting via settings:

• 📱 Go to Settings. → Mi Account and click "Log Out».
• 📧 Open the Settings. → Accounts and synchronization → Google and delete your profile.
• 🔒 If you have a lock screen installed, delete the password in the "Passwords and security" section».

If the phone is already reset and requires an account, and you remember the data, just enter it. If the data is lost, the unlocking procedure becomes a complex technical process that requires specialized software.

💡

Signing out of Mi Account and Google before reset is the only guarantee that there are no problems with blocking FRP after the reboot.

Solving problems after discharge

Once the phone is cleaned and turned on, the initial setup phase begins, and users often find the device warming up or discharges quickly in the first hours of operation, which is normal behavior: the system indexes files, updates applications, and configures background services.

However, if the phone is hanging on the logo for more than 15-20 minutes, there may have been a firmware failure or damage to system files, in which case it may be necessary to flash the device through the computer using the Mi Flash utility and pre-downloaded stock firmware.

Sometimes, after a reset, Wi-Fi or Bluetooth stops working. This may be due to residual network settings. Try resetting the network settings through the Settings menu → Connection and Sharing → Reset Wi-Fi, mobile networks and Bluetooth. This action will not affect your personal files, but will return network settings to factory values.
