How to return the factory theme to Xiaomi Redmi 9T: 5 proven ways

Why users want to return the standard MIUI theme

Xiaomi Redmi 9T with factory-made MIUI firmware comes with a proprietary theme that is optimized for the hardware of the device. However, after installing third-party themes from the Theme or customizing through the Design Settings, many face problems ranging from slow animation to complete interface failure. 80% of cases are to blame for incorrectly installed theme packages or conflicts with system updates.

Return factory theme may be required after experiments with custom firmware (for example, Pixel Experience or LineageOS), when the user decides to roll back to the MIUI. It is important to understand that the recovery process depends on the current state of the device: whether it is running normally, loaded in Fastboot, or even “burst” after a failed patching.

In this article, we’ll look at all the current methods, from simple reset via settings to manually flash through the Mi Flash Tool. Each method is illustrated with screenshots (for MIUI 14) and is accompanied by warnings about possible risks. If your Redmi 9T does not turn on, immediately go to the disaster recovery section.

Method 1: Reset themes through standard settings

The safest way is to return the factory theme directly to the MIUI interface if the system is loading normally, which works on all firmware versions for Redmi 9T (including MIUI 12/13/14) and does not require superuser rights (root).

Method 2: Complete reset (Hard Reset)

If the theme reset didn't work or the system was unstable, you'd have to use a hard reset, which deletes all user data, including the themes you've installed, but saves the factory firmware. On the Redmi 9T, the procedure takes 5-10 minutes.

Step-by-step:

1. Turn off your smartphone.

5. Once you have finished, select Reboot → Reboot to System.

Important nuances:

• 🔋 The battery must be at least 50% charged, otherwise the process may be interrupted.
• 📱 If after the reset, the device requires you to enter a Mi Account, use the data from the previously associated account.
• 🔄 On some versions MIUI After the reset, the last theme used is automatically installed. In this case, repeat Method 1.

💡

If the device does not turn on after reset for longer than 15 minutes, remove the battery (if possible) or press the power button for 20 seconds to force a reboot.

Method 3: Removing themes via ADB (for power users)

If the standard methods didn’t work and root rights didn’t work, you can use Android Debug Bridge (ADB), which allows you to manually delete third-party theme files without affecting user data, and is suitable for Redmi 9T on any version of MIUI (including MIUI 14).

What you need:

adb shell pm uninstall -k --user 0 com.android.theme.icon_pack.redmi.default


adb shell pm uninstall -k --user 0 com.miui.thememanager

⚠️ Note: Deleting theme system packages may cause the theme application to crash, in which case you will need to reinstall it via APKMirror or reset settings.

Method 4: Emergency Recovery via Fastboot

If the Redmi 9T does not load or is getting stuck on the Mi logo, you will need to flash the factory firmware through the Mi Flash Tool, which is guaranteed to return the stock theme, but delete all data and require an unlocked bootloader.

If you have root rights (e.g., through Magisk), you can manually replace the theme files with standard ones, a method that is suitable for advanced users, as it requires working with system folders.

Instructions:

2. Using Root Explorer or Mixplorer, go to /data/system/theme/.
3. Delete all files in this folder.
