How to Uninstall System Apps on Xiaomi Redmi 9T

Owners of Xiaomi Redmi 9T smartphones often face intrusive pre-installed software that takes up precious space and consumes processor resources. Removing system applications allows not only freeing up internal memory, but also significantly speeding up the MIUI interface. Many users do not even suspect how many background processes are started immediately after the screen is turned on, consuming battery power.

The cleaning procedure does not require obtaining superuser rights (root), which retains the official warranty on the device. However, interfering with system files requires care, since removing critical components can lead to unstable operation of the gadget. We will consider safe methods that are suitable even for beginners in the Android world.

In this article, we will take a closer look at device preparation, installing the necessary drivers, and step-by-step removal of bloatware. You will learn to distinguish secure-to-remove services from those needed for the basic functionality of the phone. Proper optimization will turn your Redmi 9T into a more responsive tool.

Redmi 9T Preparation for System Software Removal

Before we start taking drastic measures, we need to set up the smartphone properly, and the first step is to activate the developer mode, which is hidden by default for security purposes, and without that step, the computer will not have enough rights to manage the application packages.

Find the Settings menu → On the phone and press quickly 7-10 field-by-field "Version" MIUI». After the message "You became a developer" appears, go back to the main settings menu. → For developers.

In the list you need to find and activate the item "Debugging by USB». It is also important to include the option “Installation through” USB» and «USB-debugging (security settings only)" if available in your firmware version, this will allow the computer to interact with the system at a deep level.

⚠️ Note: When you include debugging on USB Confirm the action, but remember that you should only connect the phone to trusted computers to avoid data theft.

A high-quality job will be required USB-cable, preferably original or certified MFi/MFi, Because cheap analogs often only support charging. 9T to the PC and select the “File Transfer” mode in the notification on the smartphone screen.

The necessary tools to work with ADB

The main tool for removing system applications is the utility ADB (Android Debug Bridge), a console program that allows you to transfer commands directly to the Android operating system. To simplify the work, there are graphical shells, but knowledge of the basic principles is necessary.

You will need to download the Platform Tools package from the official Android developer website or use specialized assistant programs. Among the most popular and secure solutions for Xiaomi, Xiaomi stands out. ADB/Fastboot Tools and Universal Android Debloater.

Installation of drivers is a critical step. If the computer does not see the phone in debugging mode, you need to install universal Google USB Driver or Qualcomm specific drivers, since Redmi 9T runs on this processor.

adb devices

If you see the serial number and device status in response, the connection is successful. Unauthorized status requires unlocking on the phone screen, and the absence of the device indicates problems with drivers or cable.

Application List Analysis: What Can Be Deleted

The most dangerous stage is the selection of candidates for removal. System applications fall into three categories: critical to download, MIUI functional modules and third-party garbage (bloatware).

You can safely remove third-party apps, pre-installed games, browsers (if there is an alternative), and duplicate services from Google and Xiaomi, for example, if you do not use Mi Browser or Mi Video, removing them will not affect the system.

It is strictly impossible to remove components with names containing Security, Settings, Framework, SystemUI. Also, leave unuched packages associated with phone, messages and work. SIM-cards, even if they seem superfluous.

Use a search by name of a package before you delete it to find information about its purpose online. Often the same service may be called differently in different regions of the firmware.

Step-by-step instructions for removal through PC

Consider the uninstallation process using a universal utility that runs through ADB. This method is preferable to manual commands, because it reduces the risk of syntactic errors. Run the program on your computer and wait for your Redmi 9T to be determined.

The program interface will display a list of all packages installed. sort them or use filters to display only system applications. tick off the packages you plan to remove. Recommended removing applications in groups of 3-5 pieces, checking the stability of work after each group.

Press Uninstall or Remove, and the system will send a command to the phone, and if you use a manual command line, the command will look like this:

adb shell pm uninstall -k --user 0 name packet

The --user 0 option means that the application is only removed for the current user, but physically remains in the system partition, which makes it easy to restore the software if necessary by simply resetting the settings.

⚠️ Warning: Do not attempt to remove applications while the phone is connected to charging or performing background synchronization. Interrupting the data transfer process can cause the launcher interface to freeze.

💡

Before mass removal, take screenshots of the list of installed applications. If after cleaning the phone starts to behave strangely, you can see exactly which packet was removed last.

Recovery of Remote System Components

If you notice that important features are missing after cleaning (e.g., the sound or notifications stopped working), you can return the system to its original state. Since we used the deletion method for the user, the data is not permanently erased.

To recover through ADB, you use the cmd package install-existing command or simply re-install through the assistant program’s graphical interface if it supports the “Restore” function. In most cases, a simple factory reset via the Recovery menu helps.

To reset, turn off the phone completely. Then press the Volume Up and Power buttons simultaneously. Hold them until the Mi logo appears, then release Power, continuing to hold Loud until the Recovery menu appears.

Use the volume buttons to navigate and the power button to select. Select Wipe Data, then Wipe All Data, and confirm the action. This will return Redmi 9T to the "out of the box" state by deleting all user data and restoring system packets.

💡

Deletion via ADB with a user 0 flag is reversible. Complete erasure of the System partition is possible only if root rights are available and carries high risks.

Alternative methods and hidden MIUI settings

PC connection is not always required. Some versions of the MIUI shell have a hidden menu that allows you to disable standard applications without root permissions, and you need to enter a special code in the "caller": ##6484## (engineering menu) or through the activity shortcut.

However, on global firmware versions for Redmi 9T, this method is often blocked, so you can use freezer apps like Ice Box or Shizuku, which require one initial setup via ADB, but then you can manage the applications directly from your phone.

Shizuku works with ADB and gives other applications enhanced permissions without rooting, a modern and secure way to manage the system, and once Shizuku is activated, you can use compatible application managers to disable them.

Also worth mentioning is the possibility of using ADB AppControl, a powerful Windows program that has a database of secure apps specifically for Xiaomi to remove, which automatically flags dangerous packets in red, alerting the user.
