Xiaomi Redmi Note 4, despite its considerable age, remains a popular device, but over time, even reliable hardware can face software errors. Slowing down the interface, sudden reboots or the inability to unlock the screen are typical symptoms that require radical measures. In such situations, the most effective solution is a complete reset to a factory state, which allows you to clean up the memory of garbage and conflicting files.
Hard Reset completely removes user data, including contacts, photos and installed apps, returning the gadget to the “out of the box” state. This is a critical step before selling a device or in deep diagnostics of software failures. It is important to understand that once the process is complete, it will be impossible to recover deleted information without prior backup.
In this article, we will take a closer look at all the available methods to restore the health of your Redmi Note 4. We will look at the standard way through the MIUI settings, using the Recovery engineering menu and remote reset via Google account. We will also focus on the nuances of unlocking the bootloader and protecting against theft so that you can safely resuscitate your smartphone.
Preparation of the device for complete reset
Before you start taking decisive action, you need to perform a number of preparatory measures that will protect your data and prevent the phone from turning into a “brick”. First of all, make sure that the battery charge is at least 50-60%, as the process of formatting memory partitions can take time and requires stable power. If the device turns on, be sure to back up important data through the cloud service Mi Cloud or copy files to your computer.
Special attention should be paid to the account Google and Mi Account associated with the device. Android security feature FRP (Factory Reset Protection), which locks the phone after a reset, requiring you to enter a password from the last used account. If you forget this data, unlocking Redmi Note 4 will be extremely difficult, so it is recommended to log out of all accounts in advance or firmly remember logins and passwords.
💡
Before the procedure begins, remove SIM-microSD card and memory card to avoid accidental formatting of external media or damage to their file system.
It is also worth checking for important system updates if you plan to just refresh the system but don't want to lose data.However, for a clean reset, it is better to use the current firmware version. Make sure you know the pattern lock or digital password if it is installed, as sometimes the system may request confirmation before starting the cleanup procedure.
☑️ Checklist before reset
Method 1: Reset via the MIUI settings menu
The safest and easiest way to return to factory settings is directly from the operating system that is running. This is ideal if the screen is touch-sensitive and the interface is not hanging. First, go to the main menu and find the Settings icon, which is usually a gear, and in the list that opens, you need to scroll down to the About Phone section.
Inside the About Phone menu, you'll find the Reset option at the bottom of the list, and the system will alert you that all data will be deleted, and then tell you to choose the type of cleanup. You'll need to click on the Erase everything button, and then the final countdown timer warning will appear on the screen, during which you can cancel the operation.
⚠️ Warning: If the device has Find Device enabled, the system will require you to enter your Mi Account password before starting a reset.This is a theft protection that cannot be circumvented by simply pressing buttons.
Once confirmed, the phone will restart and the formatting process will begin. The screen may go out and light up several times, and the Xiaomi logo will be displayed longer than usual. Do not try to interrupt this process, even if it seems to you to be hanging, at which point the memory partitions are deep cleaned, and the interference can damage the file system.
Method 2: Hard Reset with Recovery Mode
If the operating system does not boot, the phone goes into an endless reboot cycle (bootloop) or the screen does not respond to touch, you need to use Recovery Mode Recovery Mode. This method works at the low-level software level and does not require access to the desktop. To enter this mode on the disabled Redmi Note 4, you need to press the Volume Up button and the Power button simultaneously.
Hold both buttons until the Mi logo appears, and then the power button can be released while you keep the volume key on. In a few seconds, the Main Menu menu will open, which is controlled by the volume buttons (up/down), and the choice is confirmed by the power button. You need to find the Wipe Data item and select it.
In the next menu, select the Wipe All Data option. The system will request confirmation again by selecting Confirm. After the cleaning process is completed, which takes a few seconds, the screen will display the message "Data wiped successfully." Then you will return to the main menu by selecting Back to Main Menu, and click Reboot -> Reboot to System.
⚠️ Note: Some firmware versions (especially Chinese ones) may require unlocking the bootloader via a computer with the Mi Unlock Tool after resetting via Recovery if the phone was previously linked to an account.

Method 3: Remote reset via Google Find My Device
If you have forgotten your pattern lock or screen lock password and your phone is locked but connected to the Internet, you can use Google’s service. This method is effective if you have a Google account activated and geolocation enabled on your device. You need to go to google.com/android/find from any other device and log in under the same account as the blocked Redmi Note 4.
Once you have successfully logged in, it will try to locate your device, and in the menu on the left or on the map, select the option to Clear the device (Erase Device), the system will issue a warning that all data will be deleted irrevocably, and once you have confirmed the action, you will send a command to the phone, which, if there is Internet, will reset.
This method also bypasses the lock screen, but it doesn't remove FRP protection. Once turned on, the phone will require you to enter a login and password from a Google account that was synchronized before reset, a security measure that prevents unauthorized users from using stolen devices.
| Resetting method | Access to the OS is required | Data security | Difficulty |
|---|---|---|---|
| Through Settings. | Yes. | Complete removal | Low. |
| Recovery Mode | No. | Complete removal | Medium |
| Google Find My Device | No (we need the internet) | Complete removal | Low. |
| Mi Cloud (remotely) | No (we need the internet) | Complete removal | Low. |
Mi and FRP account issues after reset
One of the most common problems after performing Hard Reset on Xiaomi devices is blocking activation. If you did not log out of Mi Account before reset, the system will require you to enter a password when you first set up, due to the company's security policy aimed at protecting the owner's data in the event of a device being stolen.
If you remember the password, just enter it in the appropriate field. In case of loss of login data, you can restore access through the official website i.mi.com, following the procedure for restoring the password to the associated phone number or email. SIM-The card to which the account was registered was active and was on another phone to receive the SMS code.
💡
FRP (Factory Reset Protection) is the security standard for Android and is not a virus or a breakdown.
In some cases, especially on older versions of MIUI firmware, users have experienced activation errors due to server or time issues. Make sure that the date and time on the device (if you can change them before entering a password) are set correctly and the connection to Wi-Fi is stable. Sometimes waiting for 24-72 hours helps, during which security servers can unlock the device with frequent login attempts.
What to do if the phone does not turn on after resetting
When the Redmi Note 4 does not load beyond the logo or reboots after resetting, it can indicate a system file corruption or hardware malfunction, often when the formatting process has been interrupted due to battery discharge or memory failure. First of all, try to force the device to restart by holding the power button for 10-15 seconds.
If a simple reboot does not help, you may need to flash the device using your computer and the Mi Flash Tool utility. For this, the phone must be switched to Fastboot mode (clamping the volume down button and connecting it to the phone). USB-cable) and connect to a PC, but this procedure requires a firmware file and certain technical skills.
⚠️ Warning: Incorrect flashing or interrupting the Fastboot data record can permanently disable the device. If you are not sure about your actions, you should contact the service center.
Also worth considering is the battery status. On older models like the Note 4, the battery may have degraded and there's not enough voltage to start the system normally after the energy-intensive reset process. Leave the phone charging for a few hours even if the indicator doesn't burn, and then try again to turn on.
