Despite their age, the Redmi Note 4X series remains popular thanks to the robust Snapdragon 625 processor and metal body. However, over time, the MIUI operating system can start to work unstable: freezes, applications fly out, and the battery runs out faster than usual. In such situations, the most effective solution is to completely reset the device to factory parameters, which allows you to return the smartphone to its original speed.
The return procedure deletes all user data, including contacts, photos, installed apps and account settings. It is important to understand that this step is irreversible without a pre-created backup. Many users ignore the need to save important files, which leads to irretrievable loss of information.
There are two main ways to perform Hard Reset on the Xiaomi Redmi Note 4X: through the operating system settings menu if the phone is turned on and responding to commands, and through Recovery mode if the device is locked or not booting. The method depends on the current technical condition of the gadget and access to its interface. In both cases, the result will be identical - a clean system without user debris.
Preparation of the device before the discharge procedure
Before you start the cleanup process, you need to do a series of preparatory steps to secure your data and ensure that the operation is completed successfully. The first step should always be to create a backup. The MIUI shell has a handy backup tool built in, which allows you to save contacts, messages, call logs and system settings. You can find it along the way Settings → Advanced Settings → Copy and Restore.
The second critical point is battery power. The process of formatting the internal memory requires stable power, and if the phone turns off in the middle of the procedure, the file system can be damaged. 60-70%, Or you better plug it into the charger for the duration of the operation. SIM-MicroSD card and memory card so you don’t accidentally format external drives if you choose the appropriate option.
☑️ Checklist before reset
Don't forget to check for a Google account and Mi Account. After a reset, the system can request authorization to an account that was synced to the device earlier (FRP protection). If you don't remember the password from your Google account, it's better to delete it from your phone's settings before starting the reset, which will save you from having to restore access through your computer or service centers.
Method 1: Reset via Android Settings Menu
This is suitable for users whose Redmi Note 4X smartphones are functioning normally, but require cleaning of accumulated software debris. The interface allows you to reset without using physical buttons, which reduces the risk of accidentally hitting other download modes. First, go to the main menu and select Settings, which is usually indicated by the gear.
Then scroll down to the bottom and find the About Phone section, and inside that menu, at the bottom of the screen, you'll have a Reset button or Factory Reset, and you'll be warned that all the data will be deleted, if you have a pattern lock installed on your phone, or if you have a pattern lock installed on your phone. PIN-This is a security measure that prevents the accidental reset of someone else's device.
What is an Erase SD card?
Once confirmed, the system will restart and start the cleaning process. The screen can go out and light up several times — that's normal behavior. Don't try to interrupt the process or remove the battery (which, by the way, is not removable in the Redmi Note 4X), and when it's finished, the phone will turn on as a new one, suggesting you choose a language and connect to Wi-Fi.

If the phone is tied to a Mi Account, be sure to log out before resetting via Settings → Mi Account → Sign out, otherwise activation lock will work.
Method 2: Hard Reset with Recovery Mode
If Xiaomi smartphone does not turn on, hover on the logo or does not respond to the touch of the screen, the only way out is to use Recovery mode. This method works at the system level and does not require access to the Android interface. To enter this mode, you need to completely turn off the device, and then press the key combination: Volume Up and Power button.
Hold both buttons at the same time. Once the Mi logo appears, you can release the power button, but keep holding the Volume Up until the Recovery menu appears. In this menu, the touch screen does not work, so the navigation is done with volume buttons (up/down), and the choice is confirmed by the power button. You need to select Wipe Data.
⚠️ Warning: Recovery mode does not allow you to return deleted files. Wipe All Data destroys all information irretrievably.
Once you select the Wipe Data, the system can request confirmation by asking you to select Wipe All Data. Confirm the action, and the formatting will begin. The process takes from 30 seconds to several minutes. After the end, a successful reset message will appear, and the phone will prompt you to return to the main menu (Back to Main Menu) or reboot (Reboot).
Comparison of data dumping methods
Users often wonder which method is best for their situation, and both methods lead to the same result: a complete cleanup of the user partition, but there are nuances about convenience and control of the process. Below is a table that helps determine the choice of method.
| Parameter | Through Settings. | Through Recovery. |
|---|---|---|
| Availability | Only if the phone turns on. | It works even when the loading fails. |
| Difficulty | Minimum (interface) | Medium (physical buttons needed) |
| Risk of error | Low. | Medium (incorrect press) |
| Implementation time | 5-10 minutes | 3-5 minutes |
It’s worth noting that Recovery is often the only way to unlock a device if you forget the pattern lock, but if the phone is linked to a Google account, you’ll still need to enter your account password after that reset. This is a standard procedure for protection against theft, known as FRP (Factory Reset Protection).
Solving Common Problems After Resetting
After the Redmi Note 4X When you reboot, you may find yourself in a situation where the device doesn't turn on for a long time or hangs on the logo, a phenomenon called bootloop, which is often because the first run after formatting takes much longer than usual. The system must verify the integrity of the files and restore the basic services. 10-15 without trying to turn off the phone immediately.
If the phone is turned on but running slowly or discharges quickly, this may be due to background optimization processes. MIUI shell indexes files and updates installed system applications. Let the device lie on charging with Wi-Fi connected for about an hour. It is also recommended to check for system updates along the Settings → About Phone → System Update.
⚠️ Note: If after resetting the phone requires a password from a Mi Account that you do not remember, you can officially unlock the device only through the mi.com website with a check about the purchase.
In rare cases, a reset may cause a network to go missing or a sensor to fail, indicating deeper problems, possibly damage to the system partition or hardware failure, and a simple reset will not help, and you will need to flash the device through your computer using the Mi Flash Tool utility.
Optimize the Redmi Note 4X after returning to factory settings
When you get your smartphone back to factory, you get a blank slate. To keep the Xiaomi Redmi Note 4X happy with performance as long as possible, don't rush to install hundreds of apps at once. Start with a basic setup. Disable unnecessary system services that consume resources. For example, ads in MIUI system applications can be annoying, but you can turn them off in security and privacy settings.
Pay special attention to battery setup. The Snapdragon 625 processor is energy efficient, but older batteries can behave unpredictably. Go to Settings → Battery and select Balanced Mode. Avoid Performance Mode if you don't play heavy games because it causes the case to heat up. It's also helpful to set up automatic memory cleanup so that the app cache doesn't accumulate too quickly.
💡
The first start after a reset is the best time to install only the necessary applications so as not to clog the system again.
Remember to reboot your device regularly. In an Android environment, this frees up RAM and ends the hanging processes. For the Redmi Note 4X, it is optimal to reboot every 2-3 days. This is a simple habit that prolongs the life of the operating system and maintains a high response rate of the interface.
