How to Delete Data from Xiaomi Redmi: Complete Reset and Cleanup

Xiaomi and Redmi smartphones today store vast amounts of personal information, from photos and correspondence to banking apps and passwords. Before selling a device, transferring it to another user or even in case of serious system failures, there is an urgent need to completely clean up internal memory.

A complete removal procedure known as Hard Reset or factory reset returns the gadget to the state in which it left the assembly line.This ensures that the new owner does not gain access to your accounts, social networks and sensitive documents. It is important to understand the difference between a conventional cache cleanup and deep system formatting.

In this guide, we will take a detailed look at all available cleaning methods, from standard menus to using the engineering mode, learn how to properly prepare your device to avoid being blocked by a Google or Mi Account account, and what steps to take if the phone does not turn on.

Preparing the device for complete removal of information

Before any manipulation of system files begins, a number of preparatory steps must be taken, and ignoring this step can lead to the loss of important contacts or locking the device after a reboot. Backup is the first and most important step that should not be missed.

Make sure that the battery charge is at least 50-60%. The process of formatting internal memory is energy intensive, and the sudden shutdown of the smartphone while writing system files can damage the system or boot partition, turning the device into a "brick". SIM-MicroSD card and memory card, if installed so as not to accidentally format external media.

Be sure to check your linked accounts. If you just reset your settings without first logging out of your Google Account or Mi Account, FRP (Factory Reset Protection) security will work. The new owner will not be able to activate the phone without entering your login and password, so logging in and then logging out of your accounts is a critical procedure.

⚠️ Note: Deletion of data through resetting is irreversible. Once the process is complete, it will be impossible to recover photos, messages or notes without a previously created backup, even in a service center.

Standard reset via the MIUI settings menu

The most secure and recommended cleaning method is to use the built-in functionality of the Android operating system with the MIUI shell or HyperOS. This method minimizes the risks of damage to system files and is suitable for most users whose phones are in working condition.

To start, open the main menu and find the Settings section. Scroll down to About Phone (some versions of the firmware may call it About Device). Here you are interested in the option Reset or Erase All Data. The interface may vary slightly depending on the Android version (11, 12, 13 or 14).

The system will offer several reset options. Select Erase everything. Before the final confirmation, the smartphone will show you a list of what will be deleted: photos, music, apps and settings. You will need to enter a pattern lock, PIN-code or fingerprint to confirm the operation.

Once confirmed, the cleaning process will begin. The screen may go out and light up, and the progress bar will slowly fill up. The latency can vary from 5 to 15 minutes depending on the amount of memory filled and the speed of the built-in drive. Don't try to interrupt this process with the press of buttons.

Delete data via Recovery Mode (Hard Reset)

If the smartphone is frozen, does not respond to touches or does not load to the desktop, the method of forced reset through Recovery Mode Recovery mode is used. This method works at the bootloader level and does not require access to the operating system interface.

To enter recovery mode, turn the device off completely. Then press the Volume Up and Power button at the same time. Hold them until the MI logo or Main Menu appears. The navigation in this menu is done with volume buttons (up/down), and the choice is confirmed by the power button.

• 🔹 Select the language (if available) by moving to English.
• 🔹 In the main menu, find the Wipe Data item and confirm the choice.
• 🔹 Next, select the Wipe All Data option for full cleanup.
• 🔹 Confirm the action by selecting Confirm.

After the cleanup is completed, which will take a few seconds or minutes, the system will notify you of success ("Data wiped successfully"). Select Back to Main Menu, then Reboot -> Reboot to System. The first run after such a reset will last longer than usual, as the system takes time to initially configure files.

Cleaning through Xiaomi and Find Device

In situations where the phone is lost or stolen, physical access to buttons or screens is impossible, in which case the Xiaomi Cloud service and Find Device function come to the rescue. To use this method, the device must be on, connected to the Internet (Wi-Fi or mobile network) and have an activated search function.

Go to the official cloud service website from any other device (computer or tablet), log in using the same Mi Account that was entered on the lost smartphone, and select your device from the list of available gadgets in the service interface.

From the control menu, select the Erase device function, which sends a signal to the phone that will forcibly erase all user information, which is an extreme measure, since once it is done, you can no longer track the location of the phone.

How to bypass Google FRP protection after a reset

FRP (Factory Reset Protection) security was introduced by Google to protect against theft. If you have done a reset but have not deleted your Google account beforehand, the phone will require you to enter the password from the last synchronized mailbox when you first activate it.

It's not a bug, it's not a virus, it's a regular security feature, and if you forget your password, you have to restore it through Google's website on another device, and entering the wrong password can block the login time and again.

⚠️ Attention: There are ways to get around FRP Using special utilities and code combinations, but these are often overshadowed by security updates from Google and Xiaomi.

To avoid problems, always log out of your Google account before selling. Go to Settings -> Accounts and Sync (or "Users and Accounts"), select your Google account and click Delete Account.

What to do if the data is not deleted or the phone is frozen

Sometimes the deletion process may be interrupted, or the phone may freeze on the MI logo after a reboot, which may be caused by damage to the system partition or lack of space for temporary operation files, in which cases, a repetition of the procedure through Recovery Mode is required.

If a standard reset doesn't work, try clearing the Cache partition from the same Recovery menu. Select Wipe Cache. This won't delete your personal photos, but will clear temporary system files that may have caused the conflict. After cleaning the cache, try again to completely reset (Wipe All Data).

💡

If the phone reboots cyclically after resetting, try selecting Connect with MIAssistant from the Recovery menu and connecting the device to a computer with the Mi Flash Tool installed to reinstall the firmware.

In rare cases, when software methods are powerless, the problem may lie in physical damage to flash memory. If the phone does not respond to buttons, does not vibrate and the screen remains black even when connected to charging for more than an hour, it is likely that the intervention of specialists of the service center for soldering of memory or replacement of the controller will be required.

💡

A full reset is an effective way to speed up your old smartphone and protect your personal data when selling, but requires you to make sure you have backups in advance.
