Xiaomi Redmi Note 4, despite its age, remains a popular device, but over time, even the most reliable gadget can start to work unstable. Accumulation of system debris, app malfunctions or a forgotten pattern lock are often the reasons why users are looking for a way to completely clean the device. Formatting is a radical, but often the only sure step to restore normal performance of the MIUI system.
The Hard Reset procedure brings the phone back out of the box by removing all user data, photos, contacts and installed programs. It’s important to understand that formatting the Xiaomi Redmi Note 4 is an irreversible process that requires pre-preparedness and care. In this article, we’ll take a look at all the memory cleanup methods available, from standard settings to using the engineering recovery menu.
Before you start taking action, you need to make sure you are really ready to lose all the data. If the phone turns on and responds to touch, be sure to back up important information in the cloud or on your computer. Ignoring this stage can lead to the irretrievable loss of personal archives and important documents.
Preparation for the resetting procedure
The first and most critical step is to ensure that the device is powered consistently. The formatting process can take anywhere from 5 to 15 minutes, and if the battery runs out at the wrong time, it can damage the system partitions. Charge your Redmi Note 4 to at least 60-70%, and ideally up to 100%, to have power.
The second important aspect is the Mi Account and Google account. Android security and MIUI shell have built-in protection against theft. If you reset without untidying the accounts first, the phone may lock and require a password from the previous owner. Make sure you remember the login details or delete the accounts through the settings menu in advance.
☑️ Readiness for formatting
It is also recommended to remove the microSD card if it is installed. MIUI People usually ask if you need to format internal memory or external memory, physical extraction of the card ensures that you do not accidentally erase the files on it. SIM-MicroSD and card can be used directly to reset methods.
Reset via the standard settings menu
The safest and easiest way to format the Xiaomi Redmi Note 4 is directly from the working system, which is suitable for those cases when you sell a device or just want to clean it of garbage, and you have access to the desktop.
To start, go to the main menu and select Settings, and in the list that opens, you'll find the About Phone section, which is usually at the bottom of the list, and that's where the basic tools for managing the system and device information are hidden.
Inside the About Phone section, look for the Reset button. The system will offer two options: Reset all settings (without deleting files) and Erase all data (full format). Choose the second option for complete cleanup. After pressing the button, the system can request input PIN-unlock the screen or password from Mi Account to confirm the transaction.
- 📱 Go to Settings. → The phone. → Resetting settings.
- 🗑️ Select the option to erase all data for complete deletion.
- 🔒 Enter the screen unlock password to confirm.
- ⏳ Wait for the automatic reboot and initial setup.
💡
If the phone thinks long before reset and shows animations of the cleanup, don’t panic – this is normal system behavior with a large amount of data being deleted.
Once confirmed, the phone will restart and begin the process of erasing data, which visually can look like a logo hanging.Do not touch the device until it turns on and suggests choosing an interface language. This means that the formatting of the Xiaomi Redmi Note 4 was successful.
Hard Reset via Recovery Mode
If the smartphone doesn't turn on, freezes on the logo or doesn't respond to the sensor, Recovery comes to the rescue, a low-level menu that allows you to format even when the operating system is broken. Redmi Note 4 (Snapdragon processor) uses the standard MIUI Recovery menu.
To enter this mode, turn off the phone completely. Then simultaneously press the Volume Up button and the Power button. Hold them until the Mi logo appears, after which the power button can be released, continuing to hold the volume until the main Recovery menu appears.
⚠️ Warning: In Recovery mode, the touch screen is not working. Navigation is done with volume buttons (up/down), and the choice of point is confirmed by the power button.
In the Recovery menu, find Wipe Data (or "Erase Data"). Once selected, the system will warn you of the risks. Confirm the action by selecting Wipe All Data. You will need confirmation through Confirm. You will start the cleanup process, the progress of which will be reported by the status bar at the bottom of the screen.
What to do if the Recovery menu is in Chinese?
When the cleanup is complete, the screen will display a message that says “Data wiped successfully.” Select the Back to Main Menu option, then Reboot → Reboot to System. The first run after Hard Reset can last longer than usual — up to 10 minutes, as the system creates new encrypted partitions.
Comparison of data dumping methods
Users often wonder which method to choose for their particular situation, and both of the methods described above lead to the same result: a complete cleanup of the user partition, but the terms of their application differ.
The method through settings is more convenient, because it does not require memorization of button combinations and allows visual control of the process, but it is useless if the system is “dead.” Recovery Mode is a universal tool of “last hope”, which works almost always, except in cases of physical memory failure.
| Characteristics | Through Settings. | Through Recovery. | Through Mi Flash (PC) |
|---|---|---|---|
| Access to OS is required | Yes. | No. | No. |
| Difficulty | Low. | Medium | Tall. |
| Risk of error | Minimum | Low. | Medium. |
| Implementation time | 5-10 minutes | 5-10 minutes | 15-30 minutes |
💡
Use the settings menu for routine cleaning before selling, and Recovery Mode to resuscitate a faulty or locked device.
There is also a third, more complex method, flashing through a computer with the Mi Flash Tool, which requires downloading the firmware image and putting the phone into Fastboot mode, which is recommended only for advanced users, since an error in choosing a file can lead to the need for service repairs.
Resolving problems after formatting
Once the Xiaomi Redmi Note 4 has been formatted, users may encounter a number of typical situations, the most common being a request for a password from a Google account (FRP Lock), a security mechanism that requires you to enter an email and password synchronized with your phone before reset.
If you have forgotten your Google account password, you can only re-establish access through Google’s site from another device, which is a legal security measure against theft, and you may also need to enter a password from Mi Account if Find Device is active.
- 🔋 The phone discharges quickly: in the first hours after the reset, the system indexes files and updates applications, which greatly loads the processor.
- 📡 Internet is not working: check date and time settings, if security certificates fail, the connection can be blocked.
- 📱 Touchscreen reacts with a delay: try screen calibration or check for system updates.
⚠️ Warning: If the phone is bootlooped indefinitely after reset or hangs on the logo for more than 20 minutes, the system partition is likely damaged.
Sometimes users notice that part of the memory is occupied by system files, although the phone has been cleared. This is normal: the MIUI shell and system applications take up a significant amount of internal memory Redmi Note 4. To free up space, you can remove preinstalled applications that are not in use.
