How to make the application system on Xiaomi: methods and risks

Owners of Xiaomi, Redmi and POCO smartphones often face the limitations of the MIUI or HyperOS operating system. Standard Android tools do not allow you to fully manage some programs, especially when it comes to protecting against accidental removal or hiding icons from the menu. Turning custom software into a system is a powerful tool that gives you complete control over the device.

However, this process requires caution. Unlike a normal installation, integration into the system partition affects the deep layers of the file system. Errors here can lead to unstable work of the gadget or even a cyclical reboot. Carefully study all the steps before starting the procedure to avoid fatal consequences for your device.

There are several ways to achieve this goal, from a secure method through a computer and ADB to radical intervention with superuser rights. The choice of the specific path depends on the version of Android, the model of your smartphone and the availability of an unlocked bootloader. Next, we will discuss each option in detail, weighing the risks and benefits.

Why turn an application into a system

The main reason users are looking for an answer to the question of how to make an application system on Xiaomi is protection from memory cleanup. Aggressive energy saving algorithms MIUI often kill background processes, considering them unnecessary, system processes are of the highest priority and remain active even when there is a shortage of RAM.

System status also allows you to hide application icons, which is useful for utility utilities, widgets or programs that need to run unobtrusively to the user, running only on a schedule or event. Normally, you can hide the icon without using third-party launchers.

It is also the only way to remove pre-installed debris that is built into the firmware, and if you can’t remove an application through a standard menu, giving it a “user” status (or conversely, manipulating the system) opens up access to its complete removal or freezing.

• 🛡️ Protection from closure by energy saving system and memory cleaning.
• 👻 Ability to hide icons from the general menu of applications.
• 🗑️ Full control over removal of the manufacturer's built-in software.
• ⚙️ Access to Extended Permits Unavailable to Conventional Programs.

It’s worth noting that new versions of HyperOS have made security more stringent, that simply renaming a package or moving files can now cause a signature verification error, so using proven tools and understanding partition structure becomes critical.

System status gives the application priority over user processes, which ensures its stable operation in the background.

Tools and training required

Before you make changes to system files, you need to prepare a work environment, you need a computer running Windows, macOS or Linux, as well as a high-quality computer. USB-The software part includes a set of tools Platform Tools (ADB and Fastboot).

On the smartphone, you need to activate the hidden developer menu. To do this, go to Settings → About the phone and quickly click 7 times on the MIUI or OS version. After that, the “For Developers” option will appear in the “Additional” menu.

In the developer menu, find and include the items “Debugging by” USB» and “Installation through USB». You may also need to disable App Authentication in the Google Play security section if the system blocks the installation of modified packages.

⚠️ Warning: Before any manipulations, be sure to create a full backup of data. Making changes to the system partition may result in data loss or inability to boot the system.

ADB: Secure integration without Root

The most secure way, not requiring unlocking the bootloader or obtaining superuser rights, is to use the ADB debugging bridge. This method allows you to “cheat” the system, making it consider the installed application to be system, although it will physically remain in the user partition.

First, install Platform Tools on your computer and connect your smartphone. Open the command line in the tool folder and type a command to check the connection:

adb devices

You'll see a debugging permission request on your phone screen, which you need to confirm, and then you'll need to know the exact name of the application package you want to modify.

adb shell pm list packages

Once the package name is received (e.g. com.example.app), a command is used to create pseudo-system recording. In modern versions of Android (11 and above), the classic pm install-existing method is often blocked, but with debugging enabled, Xiaomi sometimes has a privilege assignment command:

adb shell pm grant com.android.permission.INSTALL_PACKAGES

However, a more reliable way to avoid Root is to use special scripts or utilities that create a shortcut to the system list but do not move files. If your goal is to simply hide the application, use the command:

adb shell pm hide com.example.app

This method is reversible and does not change the /system partition. It is ideal for those who are afraid of bricking the device, but remember that deep integration, such as replacing system components, is not possible here.

Use of Root Rights and File Managers

For full integration, when an application must be physically in the system partition, Root rights are required. On Xiaomi, this usually means an unlocked bootloader and Magisk installed. Without this step, no further action is possible.

Once you have superuser rights, you'll need a file manager that supports system mode, such as MT Manager, Root Explorer, or Solid Explorer, which allows you to mount partitions in write mode.

The algorithm of actions is as follows:

• 📂 Copy. APK-file of the desired application in the clipboard.
• 📁 Go to section. /system/priv-app/ or /system/app/.
• 📝 Create a new folder with the name of the application.
• 💾 Put it in. APK-file inside the created folder.

It is important to set permissions for files correctly. After copying, click on the file, select Properties or Permissions and set the values: Owner - Read/Write, Group - Read, Others - Read (usually rw-r)--r-- For the folder, the rights must be 755.

⚠️ Note: Incorrect permissions to system files can cause the system to not be able to read the application when booting, causing bootloop.

Once the rights change, you have to restart the device, and if done correctly, the application will become part of the system, and you can't delete it in the usual way through the settings, just through the file manager with Root or ADB.

Specifics of working with MIUI and HyperOS sections

Xiaomi shells have their own features, including the /product partition, which is often used to house preinstalled software. In some cases, putting the application in /product/priv-app works better than in the classic /system, since this partition is less protected by integrity mechanisms when updating.

Also worth considering is the Verified Boot (AVB) mechanism, which means that if you modify the system partition directly, a warning may appear when you download that the software has been changed, which can block banking applications and Google Pay (NFC) on global firmware.

When you update your firmware by air (OTA), all changes to the system partition will be lost because the partition is overwritten by the original files. To save the changes, you either need to repeat the procedure every time, or use Magisk modules that replace files on the fly without changing the physical partition.

Possible problems and ways to solve them

The most common problem is a bootloop, which happens if the system application is damaged, has version conflicts or incorrect access rights. If the phone has stopped loading, try recovery or Fastboot mode.

In Recovery mode (if you have access to the file system), you can remove the problem APK-If you don't have access, you can only flash the device through the Mi Flash Tool to clean up the data, which is why backup is critical.

Another problem is signature conflicts: If you are trying to replace a system application (such as a browser or calculator) with your version, the signatures must match, or the system must be patched to ignore the signatures, otherwise the installation will fail or the application will not start.

Users also often find that after becoming a system application, they stop updating through Google Play. This is normal, since the Play Store sees a version conflict between the installed system version and the one available in the store. The solution is to remove the system version and install the user version, or use third-party app stores.

⚠️ Warning: Don’t try to make system applications that require constant updates (messengers, social networks) this will lead to constant conflict versions and unstable work.
