How to put the default theme on Xiaomi POCO: 3 proven ways

Changed theme to Xiaomi POCO and now you can’t get back the standard interface? Or did the system automatically apply an uncomfortable color scheme after the MIUI update? This problem is familiar to many owners of POCO smartphones – from budget POCO M6 to flagship POCO F6 Pro. Unlike the classic Redmi, there are often nuances with the return of factory settings of the the theme due to the features of the shell.

In this article, you’ll find three working methods for returning the default theme, from simply resetting through settings to manually deleting custom files. We’ll also look at why a standard theme sometimes flies off after updating MIUI 14→15, and what to do if the default button in the theme menu is inactive. All instructions are tested on current 2026 firmware and adapted to different POCO models.

Why does the POCO theme change on its own?

Xiaomi POCO users often experience a situation where, after a reboot or system update, the interface suddenly acquires unfamiliar colors, icons or fonts, the reasons for this behavior lie in the features of the MIUI shell:

• 🔄 Automatic application of topics from the cloud. If you've ever downloaded themes from a theme → Online, the system may accidentally activate them after a cache reset or update.
• 📱 Conflict with corporate functions POCO. For example, the regime POCO Launcher sometimes overrides system settings for themes.
• 🔧 Errors in configuration files. Damaged files in folder /miui/theme/ They can force the system to use a backup theme.
• 📲 Reset settings without deleting user data. In a partial reset (e.g., via Settings) → Additionally. → Resetting) topics remain in the device memory.

Interestingly, the POCO X6 Pro and new HyperOS models are less likely to have problems with the problem, as developers have fixed a bug with a spontaneous change of theme, but owners of the POCO F4/F5 on MIUI 14 have to deal with this more often.

Method 1: Return the theme through standard MIUI settings

The most obvious and safe method is to return the factory theme through the settings menu, which works on 90% of POCO devices if the system is not damaged.

1. Open the Themes app (the icon with a brush on your desktop).
2. Go to the My Themes tab (usually at the bottom of the screen).
3. Scroll down to the default or standard section (the title may vary depending on the version of MIUI).
4. Click on the standard theme preview, then select Apply.
5. Confirm the action if a reboot request appears.

If the Apply button is inactive or there is no Default section, try:

• 🔍 Update theme app via Google Play or App Store MIUI.
• 📥 Download the standard theme manually (see Method 3).
• 🔄 Reboot your phone – sometimes it helps to “exhibit” hidden options.

⚠️ Attention: On some firmware POCO (for example, MIUI 13.0.6. POCO X3 Pro) a standard topic may be referred to MIUI Default or System Default. If you don't find it, search for the keyword "default" in the themes menu.

Method 2: Reset theme settings through a hidden menu

If the standard method didn’t work, try resetting the themes through a hidden engineering menu, which is more radical, but doesn’t affect user data (photos, contacts, etc.).

Instructions:

1. Open the Phone app and type in the combination: ##6484## (some models run ##64663##).
2. You will be taken to the MIUI Test menu. Select the Theme Manager (or Themes) section.
3. Press Reset to Default (Reset to Factory).
4. Confirm the action and restart the device.

After the reboot, the theme should return to the standard. If the combination ##6484### does not work:

• 📌 Make sure to type it in the standard Phone app, not in Google Phone or other dialer.
• 🔢 Try alternative codes: ##36446339## (for MIUI 12-14) ##6484## (for MIUI 15/HyperOS)
• 🛠️ Nana POCO with HyperOS (for example, POCO X6) Engineering menus can be blocked – use Method 3.

Method 3: Manually remove custom theme through file manager

If previous methods didn't work, you'd have to manually delete the theme files that interfere with standard theme, which requires root rights or access to system folders through ADB, but it's 100% effective.

Important: Incorrectly deleting system files can cause shell failure. Follow the instructions exactly!

Steps for non-root devices (via ADB):

1. Connect POCO to your PC and enable USB Debugging in Settings → About Phone → MIUI version (click 7 times on build number, then return to Additional → For Developers).
2. Download ADB Tools and open the command line in the folder with adb.exe.
3. Enter the commands in turn: adb shell su rm -rf /data/system/theme/* rm -rf /data/user/0/com.android.themes/files/* reboot

For root devices:

1. Use Root Explorer or Solid Explorer with superuser rights.
2. Go to /data/system/theme/ and delete all files in this folder.
3. Also clean: /data/user/0/com.android.themes/files/
4. Reset the device.

⚠️ Attention: POCO with HyperOS (for example, POCO X6 Pro) deleting the theme files may cause the com.android.themes error. In this case, after the reboot, go to Settings → Annexes → Application management → Topics and click Reset Settings.

What if the theme dropped, but the icons remained custom?

A common problem after returning a standard theme is that the application icons remain changed, which is because POCO Launcher or third-party launchers (like Nova Launcher) cache icons separately from the system theme.

Decisions:

• 🔄 Launcher reset: Go to Settings → Annexes → Application management. POCO Launcher (or your current launcher).Tap Storage → Clear cache and Clear data.
• 📱 Restore Standard Icons by Hand: Clutch the Empty Space on the Desktop → Desktop settings. Select Icon Style. → Standard.

Reinstallation of the launcher

1. Download APK POCO Launcher from APKMirror (the version should match your firmware).
2. Install on top of the current version (do not delete the old one!).

adb shell cmd package install-existing com.miui.camera

How to prevent automatic change of the topic in the future?

To avoid repeating theme on POCO, follow these tips:

• 🚫 Turn off automatic themes updates: Go to Topics → Settings (⚙️) → Auto-Update Themes. Turn off the option to automatically apply new themes.

Block theme changes through ADB

adb shell settings put global theme_auto_apply 0

Create a backup copy of a standard theme

1. Download the standard theme file for your model with MIUI CF.
2. Save it to the cloud or on PC.

Regularly clean the cache of the “Themes” application

Settings → Applications → Topics → Storage → Clean the cache

On POCO with HyperOS (such as POCO X6 Pro), it is also recommended to disable the Desktop Personalization feature in the launcher settings – it sometimes conflicts with the standard theme.
