How to turn PatchWall on Xiaomi TV: full instructions with nuances

Xiaomi’s PatchWall shell is not just a launcher for smart TVs, but a complete ecosystem with content recommendations, streaming integration and easy management. After updating the firmware or resetting settings, PatchWall suddenly disappears, replacing the standard Android TV-In this article, we'll explore why this happens, how to bring PatchWall back, and what to do when the TV stubbornly "can't see" the shell.

It’s important to understand that PatchWall is not a standalone application – it’s a system component deeply integrated into MIUI for TV firmware. Disabling or deleting it (for example, via ADB) can cause the TV to malfunction.We’ll look at all the official and semi-official ways to return the shell, including factory resets, manual firmware updates, and even alternative methods for older models.

If your Xiaomi Mi TV 4/4S/4A/5 or Redmi Smart TV suddenly loses PatchWall, don’t rush to bring it to the service. 90% of the time, you can solve the problem yourself in 10-15 minutes, following our instructions.

Why is PatchWall disappearing from the Xiaomi TV screen?

There are several reasons why the PatchWall shell is not displayed, most often it is related to:

• 🔄 Update of the firmware - new versions MIUI TV Sometimes reset the launcher settings by default.
• ⚙️ Manual change of launcher through Android settings TV (for example, after installation ATV Launcher or HalLauncher).
• 🧹 Reset to factory settings – after it, the system can “forget” that PatchWall should be the main interface.
• 🚫 Removing system applications through ADB Memory Optimizers (for example, Clean Master).
• 📦 Work problems MIUI TV — rarely, but there are cases when the shell “flies” due to errors in the cache.

The most insidious situation is when PatchWall is physically present on the system (see in the list of applications), but does not start as the default launcher. This is for firmware, where Xiaomi has experimented with splitting the shell into separate components (for example, in MIUI TV 3.0-4.5), In such cases, only manual launcher assignment through the developer settings helps.

If PatchWall is lost after a firmware rollback (e.g., MIUI TV 5.0 to 4.0), this may be due to version incompatibility. Some Xiaomi TV models (e.g., the 2019 Mi TV 4X 55) require specific firmware assemblies where PatchWall is sewn into the core, and trying to install “alien” versions will result in the loss of the shell.

Official way: Enable PatchWall through settings

If the shell has not been removed or damaged, it can be returned in a standard way.

1. Open the settings of the TV (cog in the upper right corner or the Settings button on the remote).
2. Go to the Appendix section → All Appendices.
3. Find PatchWall (may be called MIUI TV Launcher or Xiaomi Home)
4. Select it and click Launch or Open by default.
5. Confirm the choice of the default launcher in the window that appears.

If there is no Open by default, PatchWall is not a system launcher in your firmware, in which case only resetting or manual firmware (more on this below) will help.

On some models (e.g. Mi TV Q1 75), the path to launcher settings may differ:

Settings → Device → Applications → Cog sign (in the upper right corner) → Default launcher

⚠️ Warning: If after selecting PatchWall, the screen flashes and returns to standard Android TV, This is a sign of damage to system files, and in this case, only a complete reset or flashing through the system will help. USB-OTG.

Resetting to factory settings: when it is needed

If PatchWall isn't enabled through settings, and it's not on the app list at all, there's probably an error when you update or reset, and in this case, a full reset is the most reliable way to get the shell back.

• 🔌 Turn off the TV from the internet (to avoid automatic updates that could break PatchWall again).
• 📱 Take a picture of the screen, sound and network settings – after resetting them you will have to adjust again.
• 🔄 Check the firmware version in Settings → About the TV, if she's older. MIUI TV 4.0, PatchWall may not be supported.

For discharge:

1. Go to Settings → About TV → Reset settings.
2. Select Delete All Data (not Network Reset!).
3. Confirm the action with a password from the Mi Account (if linked).
4. Wait for the reboot (it will take 5-10 minutes).

After resetting, the TV should automatically start from PatchWall.

• Check if there is another launcher (like Google TV Home) installed.
• Update the firmware to the latest version through Settings → System Update.
• If PatchWall never came up, go to the manual firmware (section below).

Handheld firmware via USB: when nothing helps

If the reset didn't work, and PatchWall is still missing, then there's still a manual firmware, which is suitable for power users and requires:

• 🖥️ Computer with Windows or macOS.
• 📁 Official firmware for your model (download on miui.tv or en.miui.com).
• 🔌 USB-drive (flash drive) up to 16 GB, formatted in FAT32.

Instructions:

1. Download the firmware for your model (for example, mimax95_eea_global_images_5.0.0_20230315.zip for Mi TV Q2 75").
2. Unpack the archive and copy the update.zip file to the root of the flash drive.
3. Connect the flash drive to the TV via the USB 2.0 port (usually located on the side).
4. Press the Menu + Volume Down buttons on the remote and, holding them, connect the TV to the power.
5. Release the buttons when the Xiaomi logo with the Recovery label appears on the screen.
6. Select Install update.zip from USB and confirm the installation.

It takes 10 to 20 minutes to run the firmware, and PatchWall should come back automatically after the restart.

• Does the firmware fit the TV model (e.g., the firmware for the Mi TV 4S 55" will not fit the Mi TV 4A 43")?
• Is the update.zip file corrupted (check the MD5 checksum).
• Is the TV connected to the Internet (sometimes activation via Xiaomi servers is required after firmware is installed).

⚠️ Note: The firmware resets all data, including accounts and settings, and if the TV was linked to Mi Account, you may need to re-authorize after the firmware is installed. It is also not recommended to sew TVs with an unlocked bootloader - this can lead to "bricking" (complete inoperability).

💡

Before you run your firmware, check the version of your TV chipset in documents or on the sticker at the back. For example, the models on the Amlogic T962 require firmware marked t962 in the file name, and on the MTK 9650, it requires firmware marked mtk. Installing incompatible firmware will lead to the E:Footer is wrong error.

Alternative launchers: if PatchWall does not return

If all attempts to bring PatchWall back have failed, alternative launchers may be considered, which will not replace Xiaomi’s full shell, but will add convenience:

To install an alternative launcher:

1. Download. APK-launcher file to flash drive (for example, with APKMirror).
2. Connect the flash drive to the TV and install the application through the File Manager.
3. Launch the launcher and select it as default in the settings.

Note that some launchers (such as HalLauncher) require installation permission from unknown sources.

Settings → Security and Restrictions → Unknown Sources → [Include for File Manager]

💡

Alternative launchers will not replace the functionality of PatchWall completely, but will allow you to customize the interface for yourself. For example, ATV Launcher supports the addition of tiles for frequently used applications, and Wolf Launcher – gestures control.

PatchWall on old models of Xiaomi TV: features

Owners of Xiaomi Mi TV 3 (2016-2017) and Mi TV 4 first revisions often find that PatchWall is not supported on their firmware, because these models originally came with Android TV 6.0-7.0, where the shell Xiaomi was optional.

• 📥 Install a modified firmware from the community (e.g, MIUI TV Pro from 4PDA).
• 🛠️ Use it. ADB-commands for forced inclusion of PatchWall (see section below).

adb shell pm enable com.xiaomi.mitv.home


adb shell am start -n com.xiaomi.mitv.home/.MainActivity

If the launcher doesn't start after you've run the commands, check if it's removed from the system.

adb shell pm list packages | grep xiaomi

If the list does not include com.xiaomi.mitv.home, then PatchWall was removed at the firmware level, and you can only return it by flashing it back.

⚠️ Attention: On older models 2018 years (e.g. Mi) TV 2) PatchWall is fundamentally not supported due to hardware constraints. Attempts to install the shell lead to errors in the graphics accelerator (EGL_ERROR). In this case, only alternative launchers are used.
