What to do if you removed the app “Themes” on Xiaomi: 5 ways to return the standard design

Themes app on Xiaomi, Redmi or POCO smartphones is responsible not only for wallpaper and icons, but also for the system launcher (MIUI Launcher). Its accidental removal can lead to the disappearance of icons, a malfunction of the home screen or even “fly” into safe mode. Unlike conventional programs, a simple reinstallation from the Play Market here will not work — special actions are required.

Complicating the problem, newer versions of MIUI 13/14 have the Themes app deeply integrated into the system, and removing it through Settings → Applications or third-party utilities (such as ADB AppControl) often result in loss of access to basic interface features, including the notification panel and the app menu. This article provides proven recovery options, from simple to technically complex, taking into account the features of different Xiaomi models.

If the screen turns black after deleting the theme and the icons are gone, don't panic. 90% of the time, the problem is solved without a factory reset, and the key is not to try to install alternative launchers (like Nova Launcher) until the system application is restored, which can exacerbate the software conflict.

1.Verification: Has the Themes app really been removed?

Before you start recovery, make sure that the problem is removing the application. MIUI:

• 🔍 Icons are missing, but the notification panel is working → Maybe the launcher settings are down.
• 📱 The screen flashes or reboots when you press the icons → cache-fight.
• ⚙️ No access to settings → remotely.
• 🚫 Error: “The application has stopped” MIUI Launcher» → crash-out.

To confirm the removal:

1. Open Settings → Applications → Application Management.
2. In the search box, enter “Themes”.
3. If the application is not listed (including the All Apps tab), it is removed.

If the app is there but it doesn't work, try clearing its cache and data through the same settings section. If the theme doesn't, go to recovery methods.

💡

On some models (POCO F3, Redmi K40) the Themes app may be called MIUI Themes or System Themes.

Method 1: Recovery through MIUI Recovery (without loss of data)

The safest method is to use the built-in system recovery function, which works if:

• 📲 You. MIUI 12 or newer.
• 🔧 No root rights or custom firmware.
• 📁 System files are not damaged (no errors when downloading).

Instructions:

1. Turn off your smartphone.
2. Press the Power button + Volume up to enter Recovery Mode.
3. Select a language (if required), then go to Connect with MiAssistant (the newer models may be called Repair System).
4. Connect your phone to Wi-Fi and follow the tips to restore system applications.

This method will automatically reinstall remote system components, including Themes, which will take 10-20 minutes, but an important point is that you may need to re-authorize your Mi Account after recovery.

Method 2: Reinstallation via ADB (for power users)

If Recovery Mode doesn’t help or isn’t available, you can return the Themes app via Android Debug Bridge (ADB).This method requires a computer and basic command line knowledge.

What you need:

• 🖥️ Computer with installed ADB-driver.
• 📱 Included Debugging by USB in the developer settings (Settings) → The phone. → Version. MIUI — Press 7 times, then return to Additional → For developers).
• 📄 File. APK Themes app for your version MIUI (You can download from Xiaomi.eu or 4PDA).

adb reboot #Reboot

If there is a mistake INSTALL_FAILED_INVALID_APK, signifier:

• 🔹 File. APK It's not good for your version. MIUI (check the compatibility).
• 🔹 The application is protected by the system (root rights are needed for forced installation).

4. Method 3: Reset the launcher settings (if the icons are missing, but the "Themes" are in place)

If the Themes app is not removed but the interface is lost (no icons, no gestures working), try resetting the launcher settings. This helps in 60% of cases with "mild" crashes.

How to do this:

1. Open Settings → Applications → Application Management.
2. Find MIUI Launcher (or "Luncher").
3. Click Warehouse → Clear the data and Clear the cache.
4. Reboot the phone.

After the reboot:

• 🔄 The icons will return to their standard seats.
• 📱 You may need to re-configure the main screens.
• ⚠️ Do not click “Delete Updates” – this can cause a crash.

If the reset didn't work, check if the Themes app is disabled in the settings. Sometimes it's just deactivated, not deleted.

1. Go to Settings → Applications → Application Management → Three points (menu) → Show system.
2. Find “Themes” and click Enable if the button is active.

💡

Resetting the launcher is the quickest way to get your icons back, but it won’t help if the Themes app is physically removed.

5. Method 4: Installation of a custom launcher (temporary solution)

If you can't restore the system app and you need to use your phone urgently, install a third-party launcher, which won't solve the problem completely, but it will return access to icons and menus.

Suitable options:

How to determine:

1. Download the launcher’s APK (like Nova Launcher) from the official website or Play Market.
2. Install the file and click “Home” when you request the system.
3. Choose a new launcher as the main one.

⚠️ Note: Third-party launchers do not restore system functions (e.g., notification panel) MIUI They're just masking the problem.

6. Method 5: Complete factory reset (extreme case)

If none of the methods worked, it's hard reset, which will delete all the data from the phone, so back up first:

• 📁 Save your photos/video to your PC or cloud (Google Photos, Mi Cloud).
• 📱 Export contacts to VCF-Sync the file or sync with your Google Account.
• 🔐 Write down usernames/passwords from applications (for example, via Bitwarden or 1Password).

How to reset:

1. Go to Settings → About the phone → Reset settings.
2. Choose to erase all data.
3. Confirm the action and wait for the reboot (it will take 5-10 minutes).

Once reset, the phone will return to its “out of the box” state, including the Themes app, and it’s important that if the Mi Account was tied before the reset, you’ll need to enter your account details to unlock it (Factory Reset Protection) after the reset.

⚠️ Note: On some models (Redmi Note 9 Pro, POCO X3 NFC) After reset, re-activation may be required MIUI Make sure you have access to the Internet in advance. SIM-map.
