How to Put a Standard Theme on Xiaomi Redmi 9: 3 Working Ways

Xiaomi Redmi 9 is one of the most popular budget smartphones, but its owners often face a problem: after installing custom themes through the Mi Theme Store, the system begins to slow down, and the standard MIUI interface seems more stable.

In this article, we will discuss all the current methods of returning a standard theme to Redmi 9 (including Redmi 9A/9C/9T models), taking into account the features of the MIUI 12-14 and HyperOS firmware. You will also learn how to avoid errors, for example, when the theme remains the same after a reset or the message “Failed to apply the theme” appears.

Before you start, check your firmware version: go to Settings → About Phone → MIUI version. This will help you choose the right method – some methods only work on global or Chinese versions of the software.

1. Method: Reset theme through MIUI settings

The easiest and safest method is to use the system’s built-in tools, which is suitable if you installed themes through the official Mi Theme Store and did not manually modify system files.

Instructions:

• 📱 Open the “Themes” app (icon with a brush on your desktop).
• 🔍 In the top line of the search, enter "Default" or "Standard" (in Russian).
• 🖼️ Select the first topic in the results – it is usually called "MIUI Default" or "Standard MIUI".
• 📥 Click "Apply" and confirm the action.

If the standard theme doesn’t show up in the search, try an alternative path:

1. Go to Settings → Display → Themes.
2. Scroll down and select "Standard" or "Default".
3. Confirm application.

Check your internet connection (you need to download a standard theme)

Close all applications (especially "Themes" and "Settings")

Make sure the battery is at least 30% charged.

Backup important data (in case of failure)-->

Important: Some Redmi 9 firmware may have a standard theme called "Basic" or "Classic" depending on the regional version of MIUI.

⚠️ Note: If the application icons remain changed after applying the standard theme, restart the device. 10% of the time, you need to re-use the theme in 5-10 minutes.

2. Method: Reset display settings (without data loss)

If the first method didn't work, try resetting the display settings, which won't delete your files or apps, but will return factory interface settings, including the theme.

Step-by-step:

• ⚙️ Open the Settings. → System and device → Additional settings.
• 🔄 Select "Resetting" (not to be confused with "Reset to factory"!).
• 📱 Slip on "Display Resetting".
• 🔐 Enter the unlock password (if requested) and confirm the action.

After restarting the device, check if the standard theme has been applied. If not, proceed to the next method.

What you need:

• 💻 Computer with Windows/macOS/Linux.
• 🔌 USB-cable (preferably original).
• 📦 Installed drivers Xiaomi and ADB Tools.
• ⚙️ Included debugging by USB smartphone.

Instructions:

1. Activate Developer Mode: Go to Settings → About Phone. Tap 7 times on MIUI Version. Go back to Settings → Additional Settings → Developer. Turn on USB Debugging.

adb shell


su




cmd overlay reset default

Reset the device.

⚠️ Note: Su and cmd overlay commands require Root.If your Redmi 9 is not rooted, use an alternative command: adb shell pm clear com.android.themes This will clear the cache of the Themes app, but does not guarantee a complete reset.

4. Method: Delete theme files via Root (advanced)

This method is only suitable for users with unlocked bootloader and Root rights, and allows you to manually delete custom themes files that may conflict with the standard one.

Step-by-step:

• 📲 Install a file manager with Root support (such as Root Explorer or Solid Explorer).
• 🔍 Cross the path: /data/system/theme/ or (for new versions) MIUI): /data/user_de/0/com.android.themes/
• 🗑️ Delete all files and folders except "default" or "miui_default".
• 🔄 Reset the device.

If after removing the themes, the interface is displayed incorrectly (for example, there are no icons), reset the cache:

1. Turn off your smartphone.
2. Press the Power button + Volume up to enter Recovery.
3. Select "Wipe Cache" (use volume buttons for navigation).
4. Confirm the action and restart.

💡

Before you delete the theme files, back them up! Copy /data/system/theme/ to your computer, which will help restore the interface if something goes wrong.

5. Problem Solving: Why is the standard theme not applied?

Sometimes even after all the manipulations, the topic is not reset.

If none of these methods worked, it could be a damaged firmware or a conflict with Magisk modules (if you have Root installed).

• 🔄 Perform a complete reset to factory settings (with loss of data).
• 📥 Flash your device through the Mi Flash Tool (for power users only!).

6.How to avoid problems with topics in the future?

In order not to face the need to reset the topic, follow these recommendations:

• 🛡️ Install themes only from the official Mi Theme Store - third-party APK They may contain viruses or may conflict with MIUI.
• 📊 Check your ratings and reviews before applying a new topic – if she has a lot of negative comments, it’s best to refrain from using it.
• 🔄 Regularly update the firmware: in new versions MIUI The bugs are corrected with the display of themes.
• 📱 Use light themes (no animations or complex elements) – they are less likely to cause lags.

If you like customization but don’t want to risk the stability of the system, try alternative ways to do it:

• 🎨 Use launchers (like Nova Launcher or Lawnchair) – they allow you to change icons and interface without interfering with system files.
• 🖼️ Install wallpapers and widgets through Google Wallpapers or KWGT.
• 🔧 Set up gestures and animations in Settings → Additional settings → Special facilities.

💡

Before installing any custom theme, create a restore point in TWRP (if installed) or back up through Settings → System → Backup.
