In this article, we will analyze all current methods - from a simple rollback through standard settings to restoring a backup copy of the themes.

Why the old theme is missing on the Redmi 9 Pro

Before we move on to recovery, it's important to understand why the theme might have changed. On the Redmi 9 Pro, this is usually for three reasons:

• 🔄 Automatic update MIUI. After installing a new firmware version, the system resets the theme to a standard one (most often this is the case). MIUI It's in the logic of the shell, and the developers want users to appreciate the new visual changes.
• 📱 Reset the theme settings. Sometimes it is enough to accidentally click "Apply" on another theme in the Settings section. → Themes and the previous one will disappear from the recent ones. MIUI It does not always preserve the history of the applied topics.
• 🗑️ Clear cache or theme app data if you've been cleaning memory through Settings → Annexes → Application management → Themes that may have been removed from previously downloaded themes, including custom ones.

MTZ-files (we will explain below).

Method 1: Recovery through MIUI Theme History

The quickest method is to check if the previous theme has been saved in the history of the Themes app. On Redmi 9 Pro, this section is sometimes hidden, but it can be opened through the standard menu:

1. Open the Themes app (the icon with a brush on your desktop).
2. Go to My → History section (if there is none, tap three dots in the upper right corner and select Topics History).
3. Scroll down the list, and it should show the latest themes you've applied. Find the one you want and click Apply.

If the story section is empty or your topic is not there, try another way. Importantly, the story only stores the last 5-7 topics, so if you've changed the layout for a long time, this method will not work.

💡

On Redmi 9 Pro with MIUI 12.5 and later, theme history may not show up unless you've ever gone to the Moi section. Try applying any other theme first, then go back to the story - sometimes it will "wake up" the feature.

Method 2: Reset the settings of the “Themes” application

If the theme is gone after clearing the cache or data, you can try resetting the application settings without affecting user data.This often helps to return standard MIUI themes that could have “flyed” due to a crash.

Instructions:

1. Go to Settings → Applications → Application Management.
2. Find the Topics list (or com.android.themes) and tap it.
3. Select Warehouse → Clear cache (don’t click Clear Data – this will remove all downloaded themes!).

For experienced users who want to return a specific custom theme, manual installation through.mtz files is a good option: these are archives with MIUI themes that can be downloaded from an official or third-party source (for example, themes.mi.com).

Algorithm of action:

1. Download. MTZ-the file of the theme you want. Make sure it's compatible with your version MIUI (Redmi 9 Pro is a good option for theme MIUI 12–14).
2. Transfer the file to the phone’s memory (for example, to the Download folder).
3. Open the Themes app, tap the profile icon in the top right corner and select Import theme.
4. Specify the path to the downloaded.mtz file and confirm the installation.

If there is an error when importing "Impossible to apply the theme", check:

• 🔍 Compatibility of the theme with your version MIUI (It's in the description on the site).
• 📁 Integrity of the.mtz file (try to download again).
• 🔧 Rights to install themes from unknown sources (included in Settings) → Special facilities → Topics → Allow installation from unknown sources).

4. Confirm the action and wait for the process to be completed.

⚠️ Warning: If the topic is not used after recovery, restart the phone. MIUI gives an error about the incompatibility of the backup, so the firmware has been updated - in this case, the method will not work.

Method 5: Firmware rollback (extreme case)
