How to Delete All Data from Xiaomi Redmi 4X: Full Guide

Owners of Xiaomi Redmi 4X will sooner or later face the need to completely clean the device, which may be due to selling the gadget, transferring it to another user or wanting to eliminate software errors accumulated over the long run.

Xiaomi’s Android memory cleanup process requires care, as it will be impossible to recover deleted information after the process is complete. In this article, we will take a look at all the methods available, from the standard settings menu to the Recovery engineering menu.

Before you start taking drastic measures, make sure you really want to lose all your data. If the goal is just to speed up the system, sometimes it's enough to delete the cache or extra apps, but it's just a complete cleanup that is required to solve the problem or prepare the phone for sale.

Preparing the device for complete removal of information

The first and most critical step is to back up, and many people forget that Redmi 4X will become a factory-built brick when it is reset, and that backup is the only way to save important contacts, correspondence, and media.

Be sure to check account binding. MIUI and Google have security protections against theft. If you just do a reset without untiing accounts, the new owner may face an activation lock that requires your password.

• 📸 Back up photos and videos to the cloud or to your computer.
• 📞 Sync your contacts with your Google account or export them to a.vcf file.
• 🔐 Remember or write down passwords from MI Accounts and Google.
• 🔋 Charge the battery of the smartphone to a minimum 60-70% to successfully complete the process.

⚠️ Warning: If you don't know the password from a Google account or Mi Account tied to your phone, don't reset via Recovery. you can permanently lock your device.

It is also recommended to remove the microSD card and SIM-Although the system usually asks if external memory should be formatted, physical extraction ensures that your personal files on the flash drive remain intact.

Before reset, take a photo of screens with important app settings (such as two-factor authentication settings or enterprise email settings) to restore access faster after cleaning.

Resetting data through the standard settings menu

The safest and easiest way to delete all data from the Xiaomi Redmi 4X is to use the built-in system feature, which is suitable for most users who have access to the desktop and the phone menu.

The MIUI shell interface may vary slightly depending on the firmware version, but the logic remains the same. You need to find the section that deals with the overall system settings.

Go the next way: open Settings, then go to Additional (or About Phone in newer versions) and select Reset, which is where the option of complete deletion is hidden.

You'll see a warning on the screen that all data will be deleted, and the system will offer two options: "Reset" (without deleting files) and "Clear all data." We need the second option. Click on the Clear all data button and confirm the action with the unlock password.

Once confirmed, the phone will restart and begin the cleaning process. This can take 5 to 15 minutes, at which time the Mi logo or animation may appear on the screen, do not interrupt the process or try to turn the phone off.

Using Recovery Mode for Hard Reset

If the phone doesn't turn on, it doesn't hang on the logo or the settings menu, you'll have to use Recovery mode, which is a low-level environment that allows you to control the system bypassing the main Android interface.

To enter this mode on the Redmi 4X, you need to turn the device off completely. Then simultaneously press the Volume Up and Power button. Hold them until the Mi logo appears, then release power, but keep the volume up.

In the Recovery menu, you can control volume (up/down) and power button (select). You need to select a language (if available) or go straight to Wipe Data.

• 🔽 Select the Wipe Data item with volume buttons and confirm power.
• 🗑️ Select Wipe All Data for complete deletion.
• ✅ Confirm the action by selecting Confirm.
• 🔄 Once complete, select Back to Main Menu and then Reboot -> Reboot to System.

⚠️ Note: When reset via Recovery, bypass Google protection FRP (Factory Reset Protection is not possible by standard methods. The phone will require you to enter a password from the account that was on it before the reset.

Account Deletion and Protection against Theft (FRP)

One of the most important security measures in modern smartphones is FRP (Factory Reset Protection), which prevents the stolen phone from being used after resetting. If you sell a Redmi 4X, you must delete your accounts before clearing.

To delete your Google account, go to Settings -> Accounts and Sync (or just Accounts). Select the Google account you want and click Delete your account. Similar steps should be taken for Mi Account.

If you just reset without deleting your accounts, the first time you set up your phone, you'll need to enter a password from the last synchronized account, and without that password, you won't be able to activate the device.

It’s also worth checking if the Device Search feature is enabled, and turning it off ensures that the phone won’t be tagged as lost in the future via the web interface.

Cleaning of memory cards and external drives

Internal memory isn’t the only storage. If the Xiaomi Redmi 4X has a MicroSD card installed, the data on it can be saved even after the phone is completely reset, unless you choose the formatting option.

It is recommended to remove the memory card before starting the reset procedure. If this is not possible (the tray is combined or the card is hidden), after resetting the system through the settings menu, the system may suggest formatting the card at the first installation.

To ensure that data is deleted from the flash card, it is better to connect it to the computer through the card reader and perform formatting. Select the FAT32 or exFAT file system for compatibility with the smartphone.

💡

Removing a memory card before resetting is the most reliable way to protect personal files from accidental deletion or getting to a new owner.

Note that some applications may have saved cache or data to an external card, and checking the contents of Android, DCIM and MIUI folders on a memory card before transferring the phone will not be superfluous.

Actions after reset: initial setup

Once the deletion process is complete, the Redmi 4X will restart and greet you with the language selection screen, which means the phone is back out of the box.

At this point, you'll be asked to connect to Wi-Fi. If you've been resetting your phone for yourself (to fix your mistakes), feel free to connect and log in to your account. If the phone is about to be sold, skip this step or turn off the device.

The system can offer to restore data from a backup. If you sell a gadget, refuse to restore. If you use it for yourself, this is a great time to return contacts and applications.

• 🌐 Select your region and interface language.
• 📡 Connect to a stable Wi-Fi network to activate.
• 🔒 Set up protection methods: pattern lock, fingerprint or Face ID.
• 📲 Decide whether to restore applications from the cloud.

It is important to check the version of the installed system. After the reset, the old version of MIUI may remain on the phone. Go to Settings -> About Phone and check for updates. Installing the latest security patches is critical to protecting your data in the future.
