Xiaomi smartphone users often experiment with the look of the interface by installing third-party themes from the MIUI Themes store. However, sometimes after installing poor design or a malfunction of the system, the standard interface ceases to display correctly. The screen can go out, icons disappear, and menus become unreadable. Owners of the Redmi Note 9 model face this problem regularly, especially when using modified versions of themes.
When the phone turns on but is not controlled by graphics bugs, it requires immediate intervention, and you don't panic or bring the device to the service center, because in most cases, the software failure can be fixed yourself. Theme recovery is a process of returning to the factory design settings that does not require deep knowledge of programming, the main thing is to act consistently and not interrupt the process halfway.
In this article, we will take a look at all the available methods for solving the problem, from simple actions through safe mode to forced system restart. You will learn how to delete a damaged registration file and return the phone to its original appearance. If your Redmi Note 9 stopped responding to touches due to a theme failure, follow the instructions below.
Reasons for resetting registration on Redmi Note 9
Display problems on MIUI are most often caused by conflicts between system files and downloaded resources. Third-party theme developers may make code errors, which leads to unstable launcher work. Especially often this happens with topics that have low ratings or low downloads. Incompatibility of firmware versions and theme is also a common cause.
Sometimes the user accidentally activates the hidden element function or changes the system fonts, which visually breaks the interface. In rare cases, a failure occurs after a failed system update or interrupted download of data from the cloud. Understanding the reason helps to choose the right recovery method.
- 📱 Install theme with errors in the code or damaged resources.
- 🔄 Conflict of versions between the shell MIUI topical files.
- ⚡ Sudden power outage during application of registration.
- 🚫 Attempting to install themes for other regions or models.
⚠️ Warning: If after installing the theme, the screen turns black, but the phone makes sounds or vibrates when called, the system works, but the GUI doesn't show. Don't try to blindly unlock the device, this can make navigation more difficult.
It is important to note that some themes require certain permissions that may conflict with Xiaomi’s security settings. If you recently upgraded and then applied an old theme, the probability of failure increases significantly.
Safe mode method for resetting the topic
The most effective way to get back control of your smartphone is to boot in safe mode. In this state, the Redmi Note 9 only runs system applications, ignoring all third-party themes and modifications, which allows you to get into the settings menu even if the main interface is completely out of order.
To enter this mode, Xiaomi devices typically use a combination of buttons or a shutdown menu. On some versions of MIUI, just press the turn off button on the lock screen and then hold your finger on the "Stop" item for a long time until the transition message appears. If the screen does not respond, try the physical combination: press the volume down button when the device is turned on.
☑️ Entering safe mode
After a successful boot, the screen will be marked "Safe Mode" in the corner. Now you can go to Settings → Themes and apply the standard design. If the menu does not open, try clearing the Topic app data through the app menu. Cache reset can also help eliminate temporary files that cause conflict.
To get out of safe mode, just reboot the device in the usual way. Once rebooted, the system must boot with a classic Classic or Default theme that is embedded in the phone's memory and cannot be removed.
Removing the problem theme through settings
If the phone is responsive to touch, but the interface is buggy, you can try to remove the damaged theme with regular means. Open the Themes app and go to the Profile section (human icon). This is a list of all the downloaded and applied designs. Find an active theme and click the Remove or Reset button.
Often, the system itself offers to return a standard theme when a critical error is detected. If no such suggestion is made, select a theme called Classic or Untitled (standard) and click "Apply". This action will overwrite the interface configuration files with factory values.
| Action. | The way is on the menu | The result |
|---|---|---|
| Apply the standard | Profile → Classical | Return of factory icons |
| Delete the subject | Profile → Subject → Delete | Clearing the memory from the file |
| Reset fonts | Settings → Screen → Font | Reconstruction of the text |
| Clear the cache | Settings → Applications → Topics | Deletion of temporary files |
After applying the standard theme, it is recommended to restart the device to fix the changes. If the problem was only a graphic file, the interface will fully recover. In case the Themes menu does not open or crashes, proceed to the method with the data cleaning of the application.
💡
Before removing the theme, take a screenshot of the error screen, if possible, to help you find information about a particular bug in Xiaomi support forums.
Forced reboot and data cleanup
When the interface is completely locked and Safe Mode doesn’t help, there is the option of forced reboot and data cleanup of the app theme. Press the power button for 10-15 seconds until the device vibrates and reboots. This will not delete your personal data, but reset the temporary processes.
If the problem persists after the reboot, you need to clear the theme system application data. Since you can't see the icons, touch it or use the voice control of Google Assistant if it is set up. Say "Open Settings", then find "Applications" and select "All Apps".
In the list, find the Themes app. Click on it and select Clear → Clear all data. Attention: this action will reset the application settings to those factory ones by removing the list of downloaded designs, but returns the functionality of the interface.
⚠️ Note: Cleaning the Themes data will not delete your photos, contacts or messages, only affecting the design settings and downloaded theme files.
After this procedure, the phone can behave like the first time you turn on the design part. Choose the language and basic settings if the system requires. The standard theme will apply automatically. If this method does not help, the launcher of the system may be damaged, which requires more deep intervention.
Using ADB to restore the interface
For advanced users who have USB debugging enabled, there is a computer-based recovery method: connect the Redmi Note 9 to a PC and use the Android Debug Bridge (ADB) console, which allows you to remove a problematic theme or reset your launcher settings without accessing the screen.
First, you need to make sure that the computer sees the device. Enter the command adb devices. If the device is displayed, you can proceed to reset. The command to clean the application data theme is as follows:
adb shell pm clear com.miui.themesThis command compulsorily clears the cache and application data with what is equivalent to action in the settings menu, but works even when the screen is dead, and you can also try resetting the launcher settings if the problem is:
adb shell pm clear com.miui.homeWhat if ADB can’t see the phone?
Using ADB requires caution. Introducing incorrect commands can lead to the removal of system components. pm clear is secure for user data, but removes the settings of a particular application. After completing the commands, restart the phone with adb reboot or manually.
Failure prevention and system update
To avoid a repeat of the situation, follow the safety rules when customizing MIUI. download themes only from the official Themes store, paying attention to ratings and comments. Avoid topics marked "Beta" or "Test" if you are not sure of their stability.
Update your system regularly through Settings → About Phone → System Update. Newer versions of MIUI contain compatibility bug fixes. It’s also helpful to periodically clean the store cache to prevent the accumulation of broken files.
- 🛡️ Do not set topics from unknowns APK-file.
- 💾 Make a backup of your settings before major changes.
- 📲 Check the compatibility of the theme with your version of Android.
- 🔄 Reverse updates to themes if they have lags after them.
💡
The official Xiaomi theme store is being tested for security, but even there are bugs.Always check the date of the last theme update before installing.
If you like experimenting, create a restore point or backup through the Mi Cloud, which will quickly return the phone to working condition in the event of a critical failure. Remember that the complexity of the Redmi Note 9 interface requires careful attention to installed resources.
