Xiaomi smartphone users often face the need to completely clean the device before selling, transferring to another owner or to eliminate system errors. The process of removing all information may seem intimidating to a beginner, but in the shell of MIUI or HyperOS, it is implemented as simple and safe as possible.
Before any manipulations are initiated, it is critical to realize that it is impossible to recover data deleted in this way without a pre-created backup. Android, when receiving a reset command, destroys the encryption keys, making it impossible to restore photos, correspondence and passwords by regular means, so the first step is always to carefully check cloud storage and local copies of important information.
In this article, we will take a look at all the available methods in detail, from standard resets through settings that are available to everyone, to advanced methods through the Recovery menu for cases when the device is locked or not booting. We will also touch on the important nuances associated with a Mi Account, which can become an obstacle for a new owner if you do not follow the right sequence of actions.
Preparing the device for complete data deletion
The preparation process takes longer than the cleaning procedure itself and requires careful attention to detail. Before pressing the "Erase Everything" button, make sure that the battery charge is at least 50-60%, since the process of formatting memory partitions is energy intensive and interruption on a low charge can damage system files. Also check for a stable Wi-Fi connection if you plan to synchronize the latest data before cleaning.
Special attention should be paid to the Google account and Mi Account. If you simply erase the data without first logging out, FRP (Factory Reset Protection) protection will work. The new owner will not be able to activate the phone without entering your password, which will turn the device into a brick for an outsider.
☑️ Checklist before reset
Remember to remove the MicroSD card if installed. When choosing a full clean option, the system may suggest formatting the external card as well, but physical extraction ensures that your personal files on the flash drive remain intact. SIM-card to avoid accidental reset of network settings or loss of contacts if they are stored on the SIM card, and not in the phone’s memory.
💡
Take screenshots of important app settings (such as two-factor authentication or specific Wi-Fi settings) to quickly restore them to a new device.
Standard reset via system settings
The safest and most recommended way to clean up Xiaomi is to use the built-in Settings menu functionality.This method ensures that all partitions are formatted correctly and the system overwrites the basic configuration files. First, go to the main menu and select Settings, then scroll down to the About Phone section.
In the menu that opens, find the Reset button (usually located at the bottom of the screen). The system will offer two options: Reset (without deleting personal files) and Erase Everything (complete cleaning). We need the second option. After selecting Erase, the entire phone will request confirmation of the action, warning you of the irreversibility of the process, you will need to enter the unlock password or a pattern lock to confirm your identity.
⚠️ Warning: After pressing the final confirmation button, the process will go automatically. Do not try to interrupt it, even if the screen goes out or the phone starts to heat up - this is normal operation of the memory controller.
The process time depends on the size of the drive and the number of files. On modern models with fast UFS memory, it takes from 5 to 15 minutes. The device can reboot several times, show the Mi or Xiaomi logo, and also show a progress indicator. Wait for the welcome screen with the choice of language to appear - this is a signal that the cleanup is completed successfully.
Cleaning a locked phone with Recovery Mode
If you forget your pattern lock, your password or your device is stuck and doesn't respond to touch, the standard path through the settings is not available, and in this case, Recovery Mode comes to the rescue, and it's a special diagnostic mode built into the firmware that allows you to control the system at a low level, and you need to turn off your smartphone completely to log in.
After turning it off, press the Volume Up and Power button at the same time. Hold them until the Mi logo appears, then release the power button, but keep the volume up until the Recovery menu appears. The navigation in this menu is done with volume buttons (up/down), and the choice is confirmed by the power button.
You need to find the Wipe Data item and select it. Then the system will suggest you select Wipe All Data. Confirm the action by selecting Confirm. After cleaning, select Reboot -> Reboot to System. The phone will restart clean.
| Action. | Control button | The result |
|---|---|---|
| Navigating up | Volume Up. | Moving the cursor to a point above |
| Navigating down | Loudness Down | Moving the cursor to the paragraph below |
| Confirmation of choice | Power button | Execution of the selected team |
| Exit from the menu | Reboot to System | Reboot to normal mode |
What happens if Recovery does not open?
The problem of activating Mi Account after resetting
One of the most common problems after a complete cleanup is requesting a Mi Account when you first set up, which is a theft protection mechanism, and if you didn't delete your device from your Mi profile or log out of your account in the settings before resetting, the phone will require you to enter a password from that account to continue working.
This means that even after you completely flash or reset it through Recovery, the hardware remembers the binding, and it's almost impossible to get around it without a password in legal ways, and if you buy a used phone and you see a request like that, it's a cause for concern, because the previous owner might not have cleaned the device properly.
To avoid this situation, before reset, be sure to follow the following steps:
- 🔒 Go to Settings -> Accounts and synchronization.
- 🔒 Select Mi Account and click Delete Account (not just log out, but delete from your device).
- 🔒 Do the same for your Google account.
💡
Deleting your account from settings before reset is the only way to guarantee that you will avoid blocking activation for the new owner.
Remote cleaning through Find Device
In situations where the phone is lost or stolen, physical access is not possible, but you want to erase personal data so that it does not fall into the wrong hands. Xiaomi has provided Find Device, which only works if the device has been enabled Internet and the search function was activated in advance.
To use the method, go to the official i.mi.com website from any other device (computer or phone friend). Log in under your Mi Account. In the interface, select the lost device from the list and find the Erase device button.
⚠️ Warning: After the remote erasure command, the phone will no longer appear on the map and the search function will be disabled. You will no longer be able to track its location, but the data will be destroyed.
The command will only be executed when the stolen phone connects to the Internet, if the attacker immediately turns off the device or pulls out the device. SIM-The card, the cleanup will happen later, at the first opportunity to go online, and it's an effective way to protect privacy, but it won't help to get the physical device back.
