How to Remove or Reset theme on Xiaomi Redmi Note 9: 5 working ways

Installing custom themes on the Xiaomi Redmi Note 9 via MIUI Themes is a popular way to personalize your smartphone. However, not all themes look as expected: some overload the interface with unnecessary elements, others conflict with system fonts or icons, and others even slow down the device. If you encounter a problem when the the theme “eats” the standard MIUI look, changes notification sounds or makes text unreadable, do not panic. In this article, we will analyze all the current ways to remove themes on the Redmi Note 9, including resetting through settings, manual deletion of files and even commands for experienced users.

It's important to understand that the process of removing a theme depends on how it was installed. If you downloaded it from the official MIUI Themes store, a few taps are enough on the menu. But with themes downloaded from third-party sources (.mtz files), you have to tinker longer, they often eat deeper into the system, and we'll look at both scenarios, and we'll also tell you what to do if the the the the the theme is not removed by standard methods and requires a factory reset.

1. Delete theme through MIUI Themes settings

The easiest way to get back to the standard interface is to reset the theme through the built-in Themes app, which works for all the themes installed from the official store and takes no more than a minute.

Open the Themes app (the icon with a brush on your desktop or in the app menu). In the bottom panel, click on the My Themes tab, then tap on the active theme (it will be ticked). In the window that opens, select the option to Remove or Reset to the standard. If there is no such button, then the the theme is system and not subject to removal (but it can be replaced by another).

• 📱 Step 1: Open Topics → My subjects.
• 🔍 Step 2: Find an active topic (marked as “Current topic»).
• 🗑️ Step 3: Press Remove or Reset.
• 🔄 Step 4: Confirm the action and restart the device.

⚠️ Note: If the interface remains the same after removing the theme, check the font and icon settings in the Settings section. → Screen. → Text size and fonts. Some themes change them separately from the main design.

Check the version of MIUI (Settings → About the phone)

2. Reset theme through System Settings

If the theme is not removed through the Theme app or you can’t find it in the list, try resetting it through system settings, which works even for partially deleted themes that are stuck in the cache.

Go to Settings → Themes (or Settings → Screen → Themes, depending on the version of MIUI) and see a list of themes available, including the standard one (Default or MIUI). Select it and apply it. If there is no standard theme in the list, click on the three dots in the upper right corner and select Reset to the standard one.

If after resetting some interface elements (such as icons or lock screen saver) are left from the old theme, clear the theme app cache:

1. Go to Settings → Applications → Application Management.
2. Find themes and select Warehouse.
3. Click Clear the cache and Clear the data.

3. Manual removal of theme files (for power users)

Third-party themes installed through.mtz files are often not removed by standard methods, in which case you will have to manually search and delete the theme files from the system folders, which requires root rights or access to a file manager with superuser rights (for example, Solid Explorer or FX File Explorer).

The files are stored in the following folders:

• /data/system/theme/ – This is a topic that is active.
• /sdcard/MIUI/theme/ – a folder with downloaded themes (can be deleted without root).
• /system/media/theme/default/ System themes (you can only remove them from root)

Instructions for removal:

1. Open a file manager with root access.
2. Go to /data/system/theme/ and delete the folder with your theme name (e.g. com.example.theme).
3. Clear /sdcard/MIUI/theme/ of unnecessary.mtz files.
4. Reset the device.

⚠️ Note: Removing files from /system/ If you are not sure about your actions, use other methods or contact the service center.

4. reset to factory settings (last resort)

If none of the above methods worked, the last option is a complete reset, a radical solution that will bring the Redmi Note 9 back to its original state by removing all the themes, apps and data installed. Make sure to back up important files before resetting!

Resetting instructions:

1. Go to Settings → About the phone → Reset settings.
2. Select Reset All Settings (not to be confused with Network Reset!).
3. Enter a password (if required) and confirm the action.
4. Wait for the process to be completed (it will take 5-10 minutes).

⚠️ Attention: On some firmware MIUI The last theme used may remain activated after reset. If it does, repeat the steps in Section 2 (reset via settings).

💡

Factory reset is a last resort, only use it if other methods have not worked, as it will delete all your data without the possibility of recovery (without backup).

5. Delete theme through ADB (for advanced users)

If you are familiar with ADB (Android Debug Bridge), you can delete the theme using the command line, which is suitable for those that are not deleted in standard ways, but do not require root rights.

To start, turn on USB debugging on your phone:

1. Go to Settings. → The phone.
2. Tap 7 times on the MIUI version to activate Developer Mode.
3. Return to Settings → Additional → For developers and enable USB Debugging.

Now connect the Redmi Note 9 to your computer and execute the following commands in the terminal (pre-installing ADB Tools):

adb shell


pm list packages | grep theme

This command will list all packages related to themes, find the title of your topic (e.g. com.example.customtheme) and delete it:

pm uninstall -k --user 0 com.example.customtheme

Once you have completed the command, restart the device. If the theme was system, you may need to disable it instead of deleting it:

pm disable-user --user 0 com.example.customtheme

💡

If you are not sure of the title of the theme package, use the adb shell dumpsys package | grep "theme" command to show a more detailed list.
