How to Delete All Data From Xiaomi Phone

Owners of Redmi and Poco smartphones sooner or later face the need to completely clean the device, this can be caused by selling the gadget, transferring it to another user or wanting to start with a clean slate after accumulating system debris. The process of deleting information on the shell of MIUI or HyperOS has its own features, which are important to consider so as not to lose access to accounts or important files.

Before any manipulations are initiated, it is important to understand that the complete deletion of data is an irreversible process: all photos, contacts, correspondence and installed applications will be irretrievably lost unless you back up in advance. Modern protection systems for Google and Xiaomi require careful attention to accounts, since after a reset, the phone can request confirmation of the owner.

In this guide, we will take a look at all the cleaning methods available, from the standard settings menu to advanced methods through recovery mode, and we will also discuss the important nuances of protection against theft and how to properly prepare the device for transfer to a new owner so that he does not have problems with activation.

Preparing a smartphone for complete data deletion

The first and most critical step is backing up. Without this step, recovering deleted files will be impossible or extremely difficult. Xiaomi’s built-in tools allow you to save contacts, SMS, call history and even place icons on your desktop in the cloud or on an external medium.

Special attention should be paid to your Google account and Mi Account. If you plan to sell a phone, be sure to untie the device from your accounts before you start resetting, which will prevent activation blocking (FRP) when the new owner cannot log in without your password.

⚠️ Warning: Make sure the battery is at least 50-60%. Interrupting the reset process due to battery discharge can damage system partitions and inability to load the operating system.

It is also recommended to remove SIM-microSD card and memory card. Although a reset option is usually offered to clean internal storage, physical retrieval of memory cards ensures that personal data on them will remain secure and will not be accidentally formatted.

• 📱 Check for an up-to-date backup in Google Drive or Mi Cloud.
• 🔓 Untie the device from your Mi Account via your profile settings.
• 💾 Extract. SIM-Memory card before the procedure.

Don’t forget to check the Downloads and Files folder for documents that aren’t automatically synced, and users often forget about downloaded accounts, contracts, or unique media files that are only stored locally.

Standard reset via the MIUI and HyperOS settings menu

The easiest and safest way to remove everything from a Xiaomi phone is to use the built-in recovery feature, which is suitable for most users as it is automated and minimizes the risk of errors.

To start the process, go to Settings → About Phone → Reset. In some versions of MIUI, the path may look like Advanced Settings → Recovery and Reset. The system will alert you that all data will be deleted and ask you to confirm the action.

If a pattern lock is installed on the device, PIN-An unlock code or password, the system will require you to enter it to confirm the operation, a security measure that prevents unauthorized or accidental resets by unauthorized persons.

Once confirmed, the phone will restart and the cleaning process will begin, and the Android or Xiaomi logo may be displayed on the screen, as well as the progress scale, at which point it is strictly forbidden to interrupt the process or try to turn off the device.

• 🔄 Select the option “Erase all data” for complete cleanup.
• 🔐 Enter the screen unlock password to confirm.
• ⏳ Wait for the automatic reboot and initial setup.

The time it takes to complete the operation depends on the storage capacity and the number of files. On modern models with fast memory, it takes several minutes, whereas older devices can be cleaned longer.

Resetting settings via Recovery Mode (Recovery Mode)

If the system is not booting due to errors or lockdown, you can't use the standard menu, and in such cases, Recovery Mode comes to the rescue, and it's a special mode built into the firmware that allows you to control the device at a low level.

To enter this mode, you need to turn off your smartphone completely. Then press the Volume Up and Power buttons simultaneously. Hold them until the Mi logo appears, then release the power button, keep the volume up. In a few seconds, the Recovery menu opens.

Navigation in the menu is done with volume buttons (up/down), and the choice is confirmed by the power button. You need to find Wipe Data or Clear Data. In new versions of HyperOS, the interface can be touch-sensitive, which makes it easier to do.

⚠️ Note: Recovery resets often require confirmation through the input of a special code that appears on the screen, or through a Mi Account.

After choosing a cleanup, the system can offer two options: Wipe All Data (remove everything) and Reset Settings (reset only settings). To completely delete the information, choose the first option. The process will take some time, after which the device will return to its original state.

Delete data when the screen is locked (FRP and security)

The situation when you need to delete all data with a forgotten password is one of the most difficult.Modern Xiaomi smartphones are equipped with FRP (Factory Reset Protection). Even if you do a hard reset through the buttons, the first activation of the phone will require you to enter a Google account that was synchronized with the device previously.

This means that simply “delete everything” to bypass the screen password will not work without losing access to the device in the future.If you forget the password from your Google account, it must be restored through the procedure of restoring access to the Google site from any other device.

If the phone was activated Mi Account and enabled the function “Find the device”, after reset will require the entry of a password from the account Mi. Without this data, the phone will remain locked, turning into a “brick” for the average user.

The only legal way to unlock a device without passwords in case of complete loss of passwords is to provide proof of purchase (check, warranty card) at an authorized service center, employees will be able to remove the lock of the account.

Cleaning through Fastboot and Computer (For Advanced)

For users who have experimented with firmware or experienced serious software failures, cleaning through Fastboot mode may be required.This method allows you to interact with the phone at the bootloader level using a computer.

To enter Fastboot mode, turn off your phone and press the Volume Down and Power buttons simultaneously. The screen will show an image of a hare repairing an android, with the inscription: FASTBOOT. Connect the device to the PC through the original USB-cable.

To control the phone in this mode, you will need the Mi Flash Tool utility or commands. ADB/Fastboot. The fastboot erase userdata command completely clears the partition with user data, and fastboot erase cache removes the cache.

This is the most radical method, which not only deletes files, but can also reflash partitions if you use a full image of the system, and be very careful: the wrong commands can make the device unrecoverable without soldering the programmer.

• 💻 Install Xiaomi drivers USB Driver on the computer.
• 🔌 Connect your phone in Fastboot mode to your PC.
• ⌨️ Enter the cleaning command via the command line or program interface.
