How to completely clean up Xiaomi Redmi Note 8: the complete guide

Modern smartphones like the Xiaomi Redmi Note 8 accumulate huge amounts of data that eventually begin to affect the speed of the system. Users often notice that the device begins to slow down, applications open longer, and free space on the disk mysteriously disappears.

The full reset procedure, or Hard Reset, returns the software to its original state, where it was immediately after it left the assembly line, and it's not just deleting photos or contacts, but deep formatting the internal memory partitions where the Android operating system and the MIUI shell are stored. It's important to understand that after this process, it will be impossible to recover information using standard methods.

There are several ways to do this: through the standard settings menu, through the Recovery engineering menu, or using computer utilities. The choice of the specific method depends on the current state of the device: whether the screen is turned on, whether the touchscreen is responsive, and whether there is access to the main menu. In this article, we will analyze each of the available options in detail so that you can choose the most suitable for your situation.

Preparing the smartphone for a complete reset

Before you start radical actions, you need to perform a number of preparatory measures that will protect your personal data and the process of flashing, ignoring this stage can lead to the irretrievable loss of important information such as photos, correspondence in messengers and documents.

First of all, back up all important files. You can use cloud services like Google Drive or Mi Cloud, or transfer data to your computer via a computer. USB-Pay special attention to folders. DCIM, Download and WhatsApp, as it is where the bulk of user-generated content is stored.

• 🔋 Charge the battery of the smartphone to a minimum 60-70%, Avoid sudden power outages during formatting.
• 📱 Extract. SIM-microSD card and memory card, if installed, so as not to damage their contents by software reset.
• 🔑 Remember or write down the password from your Google and Mi Account account, as after the reset, the system will require them to confirm the owner’s rights.

⚠️ Warning: If you don’t know the password from your Google account, be sure to untie the device before resetting in the settings, otherwise the protection will work FRP, The phone will become unusable.

It is also recommended to remove all lock screens, including the pattern lock, PIN-This is done through the Settings menu. → Passwords and security: Although this data is automatically deleted when reset via the settings menu, pre-unblocking reduces the risk of software conflicts during the cleanup process.

Reset via the MIUI settings menu

The safest and easiest way to clean the Redmi Note 8 is to use the built-in reset feature available to all users. This method is ideal if the phone turns on, the screen responds to touch, and you have full access to the system. The process is fully automated and controlled by the operating system itself.

To start, open the Settings app and scroll down to the very bottom of the About phone list. In the menu that opens, you will need to find the Reset option, which is usually located at the bottom of the list or in the optional three-dot menu in the upper right corner.

The system will offer two options: Reset (saves files) and Erase all data. We are interested in the second option, which initiates full formatting. After pressing the button, the system can request confirmation of the screen unlock password and password from the Mi Account.

Once confirmed, the phone will restart, and the MI logo will appear on the screen with a progress indicator, at which point the factory firmware is recorded over the current one. The duration of the process depends on the amount of memory, and can take from 5 to 15 minutes. Do not interrupt the process and do not try to turn off the device.

⚠️ Attention: During the reset process, the phone may reboot itself several times, which is normal system behavior that does not require user intervention.

Hard Reset via Recovery Mode

If the smartphone is frozen, does not respond to commands or cannot boot the operating system, Recovery mode is used. This is a low-level interface built into the device's memory that allows you to perform diagnostic and recovery operations regardless of the state of the main system.

To enter this mode on the Redmi Note 8 turned off, you need to press both the volume button and the power button at the same time. Hold them until the Mi logo appears, then release the power button, but continue to keep the volume until the Main Menu menu appears.

Navigation in this menu is done with volume buttons (up/down), and the choice of item is made by the power button. You need to find the Wipe Data item and select it. Next, the system will offer several cleaning options.

• 🧹 Wipe All Data: Completely cleanses all sections of user data, returning the phone to factory state.
• 🔒 Wipe Lock Screen Password: Removes only the screen lock password, saving personal files (not working on all versions) MIUI).
• ↩️ Back to Main Menu: Returns to the main menu without performing any actions.

Select Wipe All Data, confirm the action by pressing Confirm, and wait until the process is over. Successful completion will be marked with Data wiped successfully. After that, select Back to Main Menu and then Reboot → Reboot to System.

Importantly, on some versions of MIUI firmware, entering Recovery mode may require a Wi-Fi connection and entering a password from your Mi Account. This is a security measure to prevent the device from being stolen. If the phone requires a connection, make sure the network is stable.

Use of Mi Flash Tool and Fastboot

For advanced users or in cases of a serious software failure, there is a method of cleaning through the Fastboot mode and the Mi Flash Tool utility on the computer, which allows not only to clean the data, but also completely reflash the device, replacing the damaged system files.

To start, you will need to download the official firmware for Redmi Note 8 (codename: ginkgo) in the format Fastboot (extension.tgz) and unpack it on your computer. ADB Fastboot and the Mi Flash Tool.

Put your phone in Fastboot mode, holding down the volume and power buttons at the same time, and the screen will show an image of a hare repairing an android, and the inscription will appear on the screen. FASTBOOT. Connect the device to the PC through high-quality USB-cable.

fastboot devices

This command in the computer's command line will let you check if your PC sees your device. If the serial number is displayed, you can run the Mi Flash Tool, choose the path to the unpacked firmware, and press the Flash or Clean All button.

Using the Clean All method in the Mi Flash Tool ensures that all partitions, including cache and user data, are completely cleaned, and this is the most reliable way to eliminate software errors that cannot be fixed with standard reset methods.

Cleaning through ADB teams

Another professional method available for the Xiaomi Redmi Note 8 involves using USB debugging and the command line ADB (Android Debug Bridge), which requires pre-activation of the developer mode and the inclusion of debugging over USB in the phone settings.

To activate the developer mode, go to Settings → About Phone and quickly click 7 times on the MIUI Version. After the message “You became a developer” appears in the additional settings menu, a new section Additional → For developers will appear.

Turn on the USB debugging switchboard and connect the phone to your computer. The smartphone screen will have a request for debugging permission, which must be confirmed. Next, on the computer in the command line, type the following command to reset:

adb reboot recovery

This command will automatically restart the device to recovery mode, after which you can reset, as described in the section about Recovery. However, if the phone is already in debugging mode, you can try resetting directly, although modern versions of Android limit direct formatting commands for security reasons.

💡

Use the command "adb shell rm -rf /data/*" only if you know exactly what you're doing. In modern versions of MIUI, it may not work without root rights, and an error can lead to unstable system operation.

The ADB method is especially useful if the phone touchscreen is partially not working but the image is output.You can control the device and initiate a reset using only the volume buttons to navigate in the Recovery menu called by the command.

Deletion of accounts and protection of FRP

One of the most critical issues after a full cleanup is activating FRP (Factory Reset Protection), a Google security mechanism that locks a device if, after a reset, you try to log in with an account other than the one that was synced before the reset.

To avoid blocking, it is strongly recommended that you manually delete your Google account from your phone settings before clearing. Go to Settings → Accounts and Sync → Google, select your email address and click Delete Account.

The same procedure should be done with the Mi Account, in the MIUI shell, this is done through the Settings menu → Mi Account → Sign out. The system will require you to enter a password to confirm exit, only after successfully logging out of all accounts can you safely perform a full reset.

⚠️ Warning: When buying a used phone, always check if the previous owner has logged out of their accounts. If the phone requires the previous owner's password after turning on, it is almost impossible to bring it back to life without this data legally.

If you forgot to delete your accounts before resetting, the first time you turn on, your phone will require you to enter a password from your last synchronized Google account, which is designed to protect you from theft: even after you solder your memory or reset through Recovery, an attacker will not be able to use the device.

Frequent questions and problems after cleaning

After a complete cleanup procedure, users often face questions about the normal behavior of the device, such as the first download after a reset can last much longer than usual - from 5 to 10 minutes, this is due to the optimization of applications and the creation of a new file structure.

There may also be increased battery consumption in the first hours of operation, the system re-indexes files and updates background services, usually after 1-2 days of use, autonomy is restored to normal values.

💡

Complete cleaning is a radical but effective tool for solving software problems that requires mandatory data backup beforehand.

If after resetting the phone continues to behave incorrectly, warm up or quickly discharge, the problem may lie not in the software, but in the hardware or poor firmware assembly.
