How to install a standard theme on Xiaomi Poco X3: 3 working ways

Xiaomi Poco X3 (including the NFC and Pro versions) is known for its flexibility in configuring the interface thanks to the MIUI shell. However, after experimenting with custom themes from Theme → Online users often face problems: incorrect display of icons, slow animation or even system lags. You can return the factory look of the interface in several ways - from simple resetting themes to completely reinstalling the system fonts.

In this article, we will discuss all the current methods for returning a standard theme to Poco X3, including hidden MIUI settings that are not dokumented in the official help, and pay special attention to saving user data and preventing common errors such as the failure of the theme loading or loss of desktop wallpaper.

If your Poco X3 after installing a third-party theme began to slow down or display elements of the interface curve - do not rush to make a hard reset. In 90% of cases, the problem is solved in 5 minutes through the built-in tools MIUI 12/13/14. The main thing is to know where to look for the right options and how to apply them correctly.

1. Method: Reset themes via MIUI settings

The fastest and safest method is to use the built-in theme reset feature, which is available in all versions of MIUI starting with the 11th, and does not require superuser rights (root), which is important: this method does not affect desktop wallpaper, but will return standard icons, fonts and color schemes.

Instructions:

1. Open the Themes app (the icon with a brush on your desktop).
2. Go to My Themes section (the tab at the bottom of the screen).
3. Slip on the three dots in the top right corner and select Reset to a standard theme.
4. Confirm the action in the dialog window.

After applying the changes, the smartphone will automatically restart (this is normal for the Poco X3 on MIUI 12+).If the reboot lasts more than 3 minutes, hold the power button for 10 seconds to force the shutdown.

⚠️ Note: On some firmware (for example, MIUI EU) The reset option may not be available. №2 or №3.

2. Method: Removal of custom themes manually

If a standard reset didn’t work, the cause could be stuck theme files in system folders. On Poco X3, they are stored along the /data/system/theme/ path, but to delete them you’ll need access to a root-righted file manager, or ADB.

Step-by-step instructions for users without root:

1. Connect your smartphone to your PC and enable USB Debugging in Settings → About Phone → MIUI version (tap 7 times on the build number, then go back to Additional → For Developers).
2. Download ADB Tools and unpack the archive.
3. Open the command line in the folder with adb.exe and execute: adb shell pm uninstall -k --user 0 com.android.theme.icon_pack.fallback pm clear com.miui.themes
4. Reset the device.

For owners of smartphones with unlocked bootloader and TWRP:

1. Load into the recaveri (hold Power + Volume up when turned on).
2. Go to Advanced → File Manager.
3. Delete the folders: 📁 /data/system/theme/ 📁 /data/user_de/0/com.miui.themes/

Reboot System

3. Method: Full resetting of settings (last resort)

If previous methods failed, the radical solution is factory reset, which is guaranteed to return the standard theme but delete all user data (photos, messages, apps). Poco X3 offers two reset options:

Option 1: Through the settings menu (saves files in internal memory):

1. Open Settings → About the phone → Reset settings.
2. Select Reset Settings (not to be confused with Erase All Data!).
3. Enter the password from your Mi Account if you request it.

Option 2: Through the recaveri (full formatting):

1. Turn off the phone.
2. Press Power + Volume up to enter the Fastboot.
3. With volume buttons, select Recovery Mode and confirm with the power button.
4. Select Wipe Data → Wipe All Data from the Recovery menu.

⚠️ Attention: On Poco models X3 Pro with firmware MIUI 13+ Resetting over the recavers can result in a bootloader lock if OrangeFox Recovery was previously used.In this case, restore the stock recovery via fastboot flash recovery recovery.img.

💡

Remove before resetting SIM-- A card and a memory card. MIUI formatting may affect external drives, even if the menu indicates otherwise.

4. Restoration of standard fonts and icons

Often, after resetting themes, system fonts or application icons remain changed, this is because custom themes rewrite files to /system/fonts/ and /system/media/theme/default/. These can only be returned with ADB or Magisk modules.

Instructions for fonts:

1. Download original fonts for Poco X3 (stock fonts archive).
2. Connect to ADB and execute: adb push MiSans-Regular.ttf /sdcard/ adb shell su mount -o rw,remount /system cp /sdcard/MiSans-Regular.ttf /system/fonts/chmod 644 /system/fonts/MiSans-Regular.ttf reboot

Instructions for icons:

• 📲 Install Iconify from Google Play.
• 🔍 Select a pack of icons MIUI Default in the application directory.
• 🔄 Apply changes and restart the launcher (hold your finger on your desktop) → Launcher settings → Reset the settings).

💡

If you replace the fonts with "squares" instead of characters, you're corrupting the font files, repeat the procedure with another file source, or restore the firmware through Fastboot.

5. Problems after returning a standard theme

Even after a successful reset, Poco X3 users may encounter bugs, and here are the most common ways to fix them:

If none of the methods worked, check the integrity of system files through Check Firmware, which will show which MIUI components are damaged and need to be restored.

6 How to avoid problems with topics in the future

To avoid having to return to a standard theme, follow these rules when working with custom designs on Poco X3:

• 🔍 Before installing a theme, check its rating and reviews in Topics → Online. avoid topics with a score below 4.5★.
• 📥 Download themes only from the official store MIUI. Third-party APK-Files may contain viruses.
• 🔄 Clean the Topic app cache regularly (Settings) → Annexes → Topics → Warehouse → Clear the cache).
• 📦 Before mass installation of themes, create a backup through Settings → Additionally. → Backup.

Be careful about topics that change:

• 🎨 System animations (can cause lags).
• 🔤 Fonts (risk of "broken" symbols).
• 📱 Audio diagrams (may conflict with system notifications).

If you like custom themes but are afraid of crashes, use alternative launchers like Nova Launcher or Lawnchair, which allow you to change icons and wallpaper without interfering with MIUI system files.
