Owners of the legendary Xiaomi Redmi Note 4X smartphone often face the need to completely clean the device, which can be caused by various reasons: from the banal sale of the gadget to a new owner to serious software failures that cannot be corrected by conventional methods.
Back to baseline is a powerful tool in the arsenal of any Android user, but despite its effectiveness, it requires careful attention to detail, and the wrong actions can lead to the loss of important photos, contacts, or even locking the device with MIUI security systems.
In this guide, we will take a closer look at all the options available to restore factory settings on your Redmi Note 4X, learn how to prepare for the process, what risks exist, and how to act in emergency situations when the phone stops responding to commands.
Preparing the device for a complete data reset
Before you start active memory cleanup, you need to perform a number of critical preparatory steps. Ignoring this stage can lead to permanent loss of personal information that will not be recoverable by standard means.
Special attention should be paid to battery power. The process of formatting the system partition and reinstalling components of the Android operating system is energy-consuming. If the phone turns off at the time of writing system files, this can damage the bootloader and turn the smartphone into a “brick”.
⚠️ Warning: Make sure the battery level is at least 60-70% Interrupting the reset process due to battery discharge may disrupt the integrity of system files.
It's also critical to untie accounts. Modern versions of MIUI and Android have protection against theft. If you reset your phone without deleting your Google or Mi Account, the next time you activate it, the device will require you to enter a password from those accounts, and it will be virtually impossible to unlock your phone without access to them.
Check for important data in the following categories:
- 📸 Photos and videos in the gallery
- 📞 Contacts and call history
- 💬 Correspondence in messengers (WhatsApp, Telegram, Viber)
- 🎵 Uploaded music and documents
💡
Before reset, sync your contacts with your Google account.This will take a minute, but will save your phone book in the event of a device being lost or completely cleaned.
Method 1: Reset via the Settings Menu (Soft Reset)
The easiest and safest way to get back to factory settings is from the operating system interface, which is for most users whose phones are functioning normally but require cleaning, and you don't need any additional tools or a computer.
To start, open the main app menu and find the Settings icon. In the settings list, scroll down to Advanced Settings (in some versions of MIUI, it may simply be called “Advanced”). This is where the system management functions are hidden.
The algorithm of actions is as follows:
- 📱 Select Recovery and Resetting Item
- 🗑️ Click on the Reset option
- ✅ Activate the switch Clear all data
- 🔘 Click the Reset button at the bottom of the screen
The system will request confirmation of the action because it is irreversible, PIN-You have to enter a code or password to verify the identity of the owner, and then the deletion process will begin, which will take from a few minutes to ten minutes depending on the amount of memory filled.
☑️ Check before reset via settings
Once the procedure is complete, the phone will automatically restart. The first run will last longer than usual, as the Android system needs to re-index files and configure basic services. Don't be afraid if the greeting process takes 5-10 minutes.
Method 2: Hard Reset with Recovery Mode (If the phone is not turned on)
If the operating system is damaged, the phone goes into an infinite bootloop, or you forget the pattern lock, a standard menu reset will become unavailable, in which case a recovery mode known as Recovery Mode comes to the rescue, a low-level environment built into the device's memory regardless of the state of the host OS.
To enter recovery mode on the Xiaomi Redmi Note 4X, you need to perform a sequence of actions with the phone turned off. Press both the Volume Up and the Power button at the same time. Hold them until the Mi logo appears, then release the power button, but keep the volume.
When the Recovery menu appears (usually with a black background and text of different colors), the volume buttons (up/down) control the selection and the power button confirms the choice.
⚠️ Attention: In Recovery mode, the touch screen is not working. All navigation is done with mechanical buttons.
Then select Wipe All Data and confirm the action by selecting Confirm. The system will warn you about the loss of data again. After successful completion of the cleanup, select Back to Main Menu, and then Reboot → Reboot to System.

Solving Google Account Problems (FRP Lock)
Modern smartphones are equipped with FRP (Factory Reset Protection), a mechanism to prevent the use of a stolen or lost phone after a reset. If you perform Hard Reset, the first setup will require the phone to enter a Google account that was synced to the device before the reset.
It's not a bug or a virus, it's a regular Android security feature, and if you remember your username and password, just type them in. If you bought your phone with your hands and the previous owner didn't log out, you can't activate the device without it.
To avoid problems with FRP blocking:
- 🔓 Always delete your Google account before selling.
- 📤 Extract. SIM-The card before reset (sometimes helps)
- 🌐 Make sure the internet is off when you first set up (temporary solution)
The table below shows the main states of the block and how to solve them:
| Type of lockdown | Cause of occurrence | Decision-making |
|---|---|---|
| MI Account Lock | Not deleted Mi Account before reset | Entering a password from the Mi Account |
| Google FRP Lock | Reset via Recovery without logging out of Google | Entering Google account data |
| Screen Lock | Forgotten pattern lock or password | Complete data reset (Hard Reset) |
💡
The only guaranteed way to get around FRP is to know account details. Software bypasses are often overshadowed by Google security updates.
Reset via computer and Mi Flash Tool
For advanced users who have experienced serious software errors that cannot be solved by a conventional reset, there is a method of flashing through the PC, which allows not only to clean the data, but also to reinstall the MIUI operating system itself completely.
You will need to download the official firmware for Redmi Note. 4X (codename nikel or midori depending on the processor and the Mi Flash Tool.The phone must be switched to Fastboot mode by pressing the Volume Down button and connecting the Volume Down button USB-computer-wire.
In the Mi Flash Tool, you need to select a downloaded archive with firmware. It is critical to select the clean all option in the lower right corner. This command fully formats the userdata and cache partitions, ensuring a clean installation without remnants of old files.
Press Flash and wait until the process is complete. The green status signifies successful completion. The phone automatically reboots to the new system.
Frequent errors and methods of their elimination
When you reset, you often encounter unexpected situations, like a phone that might hang on a Mi or Android logo. If waiting 15-20 minutes doesn't help, try forcefully restarting your device by holding the power button for 10-15 seconds.
Another common problem is an update or reset error that is caused by space shortages or system partition damage, often only by completely flashing through Fastboot, described in the previous section.
⚠️ Note: If the phone is constantly requiring activation after reset or writes “Device is locked”, the bootloader may have been damaged or the device is locked up for a specific carrier.
Also worth mentioning is the date and time problem: Once reset, the time settings can get lost, leading to errors when connecting to Wi-Fi and running applications, just set the current date and time manually or wait for sync over the network.
If you have dropped your phone for sale, make sure it meets a new owner with a language selection screen, which confirms the success of the procedure and the lack of binding to your personal data.
