Smartphone users Xiaomi i Redmi often face a situation when the shell downloaded from the official store Themes no longer pleases the eye or begins to conflict with the system. The visual style, including icons, wallpapers, lock screen and fonts, can reduce the performance of the device or simply become boring over time. Returning the system to its usual appearance is not always as easy as it seems at first glance, especially if the standard delete button is inactive.
The procedure for returning to the factory design depends on the firmware version MIUI or new HyperOS, as well as on whether the theme has been fully applied or partially. In some cases, the system blocks the removal of active styles, requiring you to first switch to the default option. Understanding the architecture of the themeizer will help you avoid errors and loss of important data when resetting the interface settings.
In this article we will analyze in detail all the ways to remove a third-party theme from Android Redmi. You will learn how to force activate the standard style, clear the theme cache, and what to do if the interface freezes after an unsuccessful installation. Our recommendations will help you quickly restore the functionality of your smartphone and return it to its original appearance without the need to reflash the device.
Standard method of deactivation through the Themes application
The most obvious and safest method to return the original design is to use the built-in application Themes. This system tool manages all aspects of interface visualization. However, many users make the mistake of trying to delete the theme file directly from the storage, which does not lead to the desired result, since the active profile remains in the system memory.
First, you need to launch the application Topics on your device. In the bottom navigation bar, select the Profiletab, which is usually indicated by a person icon. The history of all downloaded and applied designs is stored here. Find the topic that is currently active in the list - it will be marked with the corresponding icon or located at the top of the list.
Click on the active topic to open a page with its description. If the theme was downloaded from the official store, a Deletebutton may appear next to the apply button. However, if you just want to remove the theme without deleting the file itself from memory, it is better to use the reset function. In some versions MIUI just click on the little man icon in the upper corner and select Themes, and then apply the standard style Classic or Default.
⚠️ Attention: If the delete button is inactive (gray), this means that the theme is protected by the developer or is a system theme. In this case, forced removal is only possible by clearing the application data.
After applying the standard theme, the visual style should change instantly. The icons will return to their factory appearance, and the wallpaper will change to standard screensavers Xiaomi. If this does not happen, it is possible that some elements, such as fonts or the lock screen, were changed separately and require an individual reset in the corresponding sections of the settings.
Forced reset through application settings
When the standard application interface Themes works incorrectly or freezes, an effective solution is to completely reset its settings. This method does not delete your personal files, photos or contacts, but clears the themer configuration, returning it to the “as after purchase” state.
Go to the main Settings of your smartphone Redmi. Scroll down the list to the section Applications and select item All applications. In the list that opens, find the application with the name Themes (or Themesif the system language is English). Be careful: do not confuse it with the application Wallpapers or Gallery.
On the application information page, find the section Memory or just the button Clear at the bottom of the screen. Click on it and select the option Clear all (or Clear All Data). The system will warn you that all application data will be deleted. Confirm the action. After that, when you restart the application Themes will behave as new, and the active theme will be reset to the standard one.
- 🔄 This method completely resets the interface personalization settings.
- 🗑️ The downloaded themes will remain in memory, but will no longer be active.
- ⚙️ You may need to re-grant the application permissions to access the storage.
It is important to understand that Clearing data does not affect other system settings such as screen brightness or sound. This is an isolated procedure that affects only the visual shell. If after resetting the phone still displays elements of the old theme, try rebooting the device so that the GUI cache is completely refreshed.
Before clearing the Themes app data, make sure you remember your Mi account password if it is required to re-authorize in the theme store.
Deleting third-party themes and configuration files
Sometimes users install themes from third-party sources, bypassing the official store Xiaomi. Such files may contain code conflicts that interfere with normal removal. In this case, you need to find the physical theme file in the device memory and delete it manually through the file manager.
Open the application File Explorer (File Manager). Go to the internal storage and find the folder MIUI. Inside it there is a directory theme. This is where all downloaded design files with the extension .mtzare stored. Find the file that matches the name of the problematic topic and delete it.
After deleting the file, be sure to clear the application cache Themesas described in the previous section. This is necessary so that the system stops referring to a configuration file that no longer exists. If you installed the theme via your computer, also check the folder Download or Downloads, as the installation file may remain there.
| File type | Location | Action |
|---|---|---|
| Theme file (.mtz) | /MIUI/theme/ | Delete manually |
| Icon cache | /data/data/com.android.thememanager/ | Clear in settings |
| Fonts (.ttf) | /MIUI/theme/customize/ | Replace with standard |
It is worth noting that deleting a theme file does not always automatically return the standard style. Often, after deleting a file, the system continues to display “broken” icons or a black lock screen. In such a situation, it is critical to apply any other theme (even a standard one) on top of the current one in order to overwrite the interface configuration files.
Why are themes not deleted?
Some themes contain hidden scripts that block their deletion to protect the developer's copyright. In such cases, only a complete reset of the phone settings helps.
Resetting the lock screen and font settings
A particular problem for users Redmi is that even after changing the main theme, the lock screen or font remains changed. This happens because in modern versions MIUI these elements are modular and can be used independently of the overall style.
To remove the custom lock screen, go to Settings → Lock screen. Here you will find Wallpaper carousel or blocking style settings. Disable all third-party modules and select the standard option. If a third-party font is used, it is replaced in the application Themes in the tab Fonts.
Select a system font in the font list Roboto or MI Sans and press Apply. This action will overwrite the font files on the system partition. Sometimes a complete reboot of the smartphone is required for changes to take effect, since fonts are cached at the graphics accelerator level.
⚠️ Warning: Installing fonts from untrusted sources may cause some characters (for example, in menus or SMS) to appear as squares. Always check that the font is compatible with your version of Android.
If standard methods do not help reset the lock screen, try temporarily setting a password or pattern if one has not been set. Sometimes switching the screen protection type initiates a reset of the visual lock settings to factory settings. After this, the protection can be turned off again.
Solving problems with frozen interface
The most unpleasant situation is the “bricking” of the interface, when after installing the theme the phone boots, but the desktop is not displayed, only black squares are visible instead of icons, or the system constantly crashes. In this case, the usual change of theme is not possible, since you cannot access the menu.
First, try calling up the multitasking menu (the square button or swipe up and hold). If the task manager is running, find the application Themes or System UI and close them. Then try opening the Themes app again through search or settings. If the interface consistently crashes, you will need to enter Safe Mode.
To enter safe mode on most smartphones Xiaomi you need to hold down the power button, and when the reboot menu appears, long press the item Turn off (or Reboot) until you are prompted to enter safe mode. In this mode, only system applications are loaded, and the third-party theme will be automatically disabled.
- 🛡️ In Safe Mode, uninstall the problematic Themes application or reset its settings.
- 🔌 Reboot your phone in the usual way to exit safe mode.
- 🚫 Do not try to install new themes until you are sure that the system is stable.
If even safe mode does not help and the phone goes into a cyclic reboot (bootloop), the only solution is to reset to factory settings via Recovery Mode. To do this, turn off the phone, simultaneously press the buttons Volume Up and Power until the logo appears Mi.

Prevention and selection of safe themes
To avoid problems in the future with the need to remove themes, you should take a responsible approach to choosing download sources. The official store Xiaomi moderates content, so the risk of downloading malicious or incompatible designs there is minimal.
Pay attention to the theme rating and the number of downloads before installing. Themes with low ratings often contain errors in the icon code or incorrect file paths, which leads to crashes in the launcher. Also check the date of the last update of the theme: old projects may not be supported by new versions. Regularly update the application itself through the store. Or Android.
Update the application itself regularly Themes through the store GetApps or Google Play. Developers Xiaomi constantly release patches that correct vulnerabilities in the theming engine. The current version of the application guarantees better compatibility with new system functions.
⚠️ Attention: The interface and menu layout may vary slightly depending on the regional firmware version (Global, China, EEA). If you do not find the specified item, use the search in the settings.
Use official themes marked "Safe" ensures that there are no scripts in the design code that can disrupt the operation of the system. Avoid themes that require root access to install if you are not an experienced user, as they can damage the system partition.
Updating the Themes application in a timely manner and using only verified content from the official store is the best protection against interface failures.
