Xiaomi and Redmi smartphone owners often face intrusive pre-installed advertising and a host of apps that cannot be removed by standard means. System garbage not only takes up precious space in internal memory, but also consumes CPU resources, reducing the overall performance of the device. For the Redmi Note 9 Pro model, this issue is especially relevant, since the MIUI shell is rich in various services that may not be needed by the user in a particular region.
Cleaning up the system of excess software is a delicate process, requiring care and understanding of the structure of Android. Incorrect removal of critical components can lead to unstable operation of the operating system or even the inability to boot the device. However, by following proven techniques and using secure tools like ADB (Android Debug Bridge), you can significantly speed up the gadget and make room for personal files.
In this guide, we will look at how to safely dispose of bloatware without obtaining superuser rights (Root).We will discuss preparing the environment, installing the necessary drivers and step-by-step execution of commands to deactivate or completely remove unnecessary packets. The main thing is to act consistently and always be able to roll back changes if something goes wrong.
Risk assessment and device preparation
Before you start modifying the system partition, you need to be clear about the consequences of your actions. Deleting standard Android applications at the system level is different from normal uninstallation through settings. You work with system packages, the absence of which can disrupt the work of related services, for example, the disappearance of the application store can break the updates of other programs.
The Redmi Note 9 Pro is characterized by aggressive optimization of background processes, so removing services responsible for the operation of the interface or notifications can lead to unpredictable failures.
⚠️ Note: Before starting any manipulations, be sure to create a full backup of important data.
⚠️ Warning: Do not delete packets that you do not know the purpose of, it is better to deactivate the application than to delete it permanently to preserve the possibility of recovery.
Required tools and drivers
To perform the procedure, you will need a computer running Windows, macOS or Linux and a high-quality computer. USB-The main tool will be the utility. ADB, which is part of the Android platform SDK Platform Tools. You should download it exclusively from the official website of the developers to avoid the introduction of malicious code through modified versions of the tools.
Besides the tools, it is critical to install the right drivers for your device. Xiaomi often requires specific drivers. USB-drivers that don't always automatically install when you connect your smartphone. Without the drivers properly installed, your computer won't be able to recognize your phone in debugging mode, and all commands will be ignored.
- 📱 The official archive of Platform Tools from the Android Developers website.
- 🔌 Original or certified USB-data-couple.
- 💻 Universal Drivers ADB Driver or Xiaomi USB Driver for Windows.
- 📂 Package Manager (optional), for example, ADB AppControl for Visual Control.
☑️ Preparation for debloat
Setup of the developer mode and debugging
The first step in preparing the Redmi Note 9 Pro smartphone for interaction with the computer is to activate the hidden menu. To do this, go to Settings → About the phone and find the line MIUI Version. You need to quickly click on it 7-10 times in a row until a pop-up notification that you have become a developer appears.
After activating the hidden menu in the section Additional → There's a new set of options for developers. You need to find the Debugging item. USB And you can turn the switch to the active position, and the system will alert you to potential safety risks -- confirm the action by pressing OK».
⚠️ Attention: When you first connect to your computer, you'll see a request for debugging permission from that computer on your smartphone screen. Make sure to tick "Always Allow" and press "OK" otherwise the commands won't run.
The problem with the security timer
Removal of applications through ADB-team
The most reliable and controlled way to clean up is to use the command line. After connecting your smartphone and opening the command line (or terminal) in the ADB folder, type the adb device command. If the phone screen has confirmed and the device serial number appears in the console, then the connection is established.
To remove a particular application, the command adb shell pm uninstall -k --user 0 name.packet. Here pm stands for packet manager, and the flag --user 0 indicates deletion for the current user, which effectively hides the application and stops its processes without affecting the system partition recovery, which makes it easy to restore the factory reset application in a pinch.
adb shell pm uninstall -k --user 0 com.miui.misystemThe above example is a command to remove a system analyzer, which is often responsible for advertising. It is important to know the exact name of the package. You can find a list of all installed packages by the command adb shell pm list packages. To find a specific application, you can use a filter, for example, adb shell pm list packages | grep miui, which will display all packages containing the name "miui".
💡
Use the team. `adb shell pm list packages -f` to see the full path APK-This will help identify an unknown application by its location in the system.
List of safe to remove system packages
Redmi Note 9 Pro owners should be careful with packet names, as they may be similar but have different uses. Below is a table with the most frequently removed MIUI components, which are considered safe for most users who do not use specific ecosystem functionality.
| Packet name | Component description | Consequences of deletion |
| :--- | :--- | :--- |
| com.miui.misystem | System services and analytics | Advertising in system applications will disappear |
| com.miui.player | Standard music player | Third-party player installation | will be required
| com.miui.videoplayer | Standard video player | Third-party player installation |
| com.miui.cleaner | Built-in memory cleaner | Free up space, clean functionality will not suffer |
| com.facebook.katana | Facebook | Deletion is secure if you don't need an account |
If you accidentally delete an important component, you can restore it with the adb shell cmd package install-existing name.packet.This will return the application to the state it was in before removal, without having to flash the entire device. Always check the packet name three times before entering the delete command.
Recovery of Remote Components and Recoil
Even with careful work, errors are possible. If after removing the system applications, the Redmi Note 9 Pro began to work unstable, persistent errors appeared or the interface disappeared, you need to roll back. The easiest way is to use the recovery command mentioned above if the device is still responding to ADB commands.
If the device went into a cyclic reboot due to the removal of critical system files, you may need to reset to factory settings via Recovery mode. To do this, press the Volume Up and Power buttons simultaneously before the Mi logo appears. In the recovery menu, select Wipe Data (data will be deleted).
💡
Team team. `install-existing` allows you to return a remote system packet without data loss if the application was deleted by the method `pm uninstall` user-only.
Alternative methods and graphical shells
For those who don’t want to work with the command line, there are graphical interfaces such as: ADB AppControl.This program automatically scans the connected Xiaomi smartphone and displays a list of all applications with clear names and a security rating for removal. ADB-background.
Using them simplifies the process, but requires installing additional software on the computer, and the advantage of the graphical shells is that there is a database that tells you whether you can delete a packet, but you don't have to trust automation completely: always read the description of the package before you apply changes.
- ✅ Convenient interface with search and filtering.
- ✅ Creating Recovery Points Before Change.
- ✅ Automatically identify safe applications for removal.
- ⚠️ Requires the installation of additional software on the PC.
