How to remove everything from your Xiaomi phone: the full guide

Owning a modern smartphone involves accumulating a huge array of digital information, from personal photos to banking applications. Sooner or later, every Xiaomi, Redmi or Poco user is faced with the question of the need to completely clean the device, this may be due to selling the gadget, transferring it to another family member, or simply wanting to start with a clean slate, getting rid of system debris and accumulated errors.

The process of deleting all data, often called Hard Reset or factory reset, is a radical but effective method of solving software problems. It is important to understand that once this procedure is completed, it will be impossible to restore deleted files without prior backup, which is why preparation should be approached with the utmost responsibility, carefully checking every step so as not to lose valuable contacts and documents.

In this guide, we will take a look at all the ways you can clean your smartphone memory in detail. We will look at standard methods through the settings menu, deeper options through Recovery Recovery mode, and advanced techniques for power users. By following these instructions, you can safely and clean your device, preparing it for a new life or a new owner.

Preparing the device for a complete data reset

Before you start deleting files directly, you need to perform a number of critical preparatory steps. Ignoring this step can lead to locking the device or irretrievably losing important data that you may not even remember to have. The first step should always be to back up all the relevant information.

Create an archive of photos, videos and documents in an ecosystem. MIUI And the new HyperOS can do this through the Mi Cloud cloud service or third-party solutions like Google Photos. Don't forget to export your call history and contact list if they're only stored in memory. SIM-Maps or phones, not synced to your Google account.

⚠️ Warning: Make sure the battery is at least 50-60%. Interrupting the reset process due to battery discharge can damage the system partition and turn the phone into a “brick».

It is also crucial to untie accounts: If your phone has Google Find My Device protection or Mi Account activated, be sure to log out before resetting.Otherwise, after cleaning, the new owner will not be able to activate the device without entering your passwords, which is a major security issue.

Standard reset via the MIUI and HyperOS settings menu

The safest and most recommended cleaning method is the use of built-in operating system functionality, which ensures that user data is deleted correctly and that the system tables are overwritten, minimizing the risk of software failures. The interface may vary slightly depending on the version of the shell, but the logic remains the same.

To start, open the main menu and find the Settings section, scroll down to About Phone (some versions of HyperOS may call it simply About) and that’s where key system management functions are hidden. Next, select Reset or Delete all data.

• 📱 Click on the “Reset Settings” button at the bottom of the screen.
• 🔒 The system will ask you to enter a pattern lock, PIN-unlock code or password to confirm the identity of the owner.
• ⏳ Once confirmed, the cleaning process will begin, which can take 5 to 15 minutes depending on the amount of data accumulated.

It is important to note that the reset menu often includes a “Clear internal memory” or “Erase all data” switch. Make sure it is activated if your goal is a complete cleanup. If you leave this item off, only the system settings will reset, and personal files (photos, music, downloads) will remain in place.

💡

Before pressing the final Reset button, visually check the list of files to be deleted that the system displays on the confirmation screen.

Cleaning through Recovery Mode (Recovery Mode)

If the operating system is not booting, the phone is stuck on the logo or you forgot the unlock password, the only option is to use Recovery Mode. This is a special diagnostic mode built into the device's firmware that allows you to perform low-level operations, including formatting memory partitions.

To enter this mode, you need to turn off your smartphone completely. Then press the Volume Up and Power button at the same time. Hold them until the Mi or Redmi logo appears, after which the power button can be released, while continuing to keep the volume. When the recovery menu appears (usually black with yellow or blue text), the volume buttons are controlled, and the power button is selected.

From the menu, select the language (if available) or immediately look for Wipe Data. Inside this section, you will have the option of Wipe All Data. Confirm the action by selecting Confirm. The system will warn you about the loss of data - agree and wait for the process to be completed. After successful completion, select Reboot -> Reboot to System.

⚠️ Warning: Recovery often requires unlocking the screen if the phone has a password set.If you don't remember the password, this method may not work without first unlocking through your Mi Account.

Delete data via computer and ADB

For advanced users who need a guaranteed result or who are preparing a device for flashing, there is a method of cleaning through the Android debugging bridge (ADB), which allows you to send a command to format directly, bypassing the phone's graphical interface, and is especially useful if the touch screen is partially not working.

This method requires that the phone has previously enabled the option “Debug over USB” in the “Developers” menu. Also, the computer must have ADB drivers installed. Connect the phone with a cable to the PC, open the command line in the folder with ADB tools and enter the command to reboot in recovery: adb reboot recovery mode.

Once in recovery mode, you can send a cleanup command, but a more radical method is to direct wipe if the device is root-nut or has the appropriate access rights, but the standard reset command looks like this:

adb shell recovery --wipe_data

Use of the ADB It gives you complete control of the process. You can see the real-time execution logs on your computer screen, it allows you to diagnose errors if the process goes wrong, for example, if a part of the memory is physically damaged, ADB-The console will immediately report a recording error that is impossible to see on the phone screen.

💡

The ADB method is ideal for remote cleaning control or when the smartphone touch screen does not respond to touch.

Comparison of cleaning methods and their effectiveness

Different ways of deleting data have their own characteristics, depth of cleaning and use cases, and understanding the differences between them will help you choose the best option for your particular situation.

It's worth noting that for a typical phone sale, Settings is enough: it overwrites the file table, making data recovery impossible for the average user, and Recovery and ADB are more commonly used in repairing, flashing, or solving critical system errors.

There is also the concept of deep cleaning to improve security: After any of the above resets, it is recommended to fill the phone’s free space with useless files (for example, record several hours of high-resolution video), and then reset again, which is an action that overwrites old memory sectors with new data, making it almost impossible to restore the original information even for intelligence agencies.
