Reset settings on the TV Xiaomi 4K: 3 proven ways

Xiaomi 4K TVs (including Mi TV 4S/4A/4X/4 Pro models) may become unstable over time, slowing down the interface, spontaneously restarting or losing Wi-Fi connectivity. In 80% of cases, these problems are solved by a complete resetting procedure that returns the device to a factory state. However, many users are afraid to perform it themselves, fearing to lose data or completely “break” the TV.

In fact, resetting on Xiaomi TV is a safe operation if you do it according to the instructions. In this article, we will discuss three official ways (through the menu, buttons on the case and using the remote), explain how to prepare for the procedure, and warn against typical errors, and if after the reset, we will give a checklist to fix them.

Important: The procedure is different for Android TVs (post-2020 models) and PatchWall (older firmware versions).

1. When you need a reset settings - 5 clear signs

Just in case, you don't have to reset your settings, it's a last resort, and here are the situations where the procedure is really necessary:

• 🔄 The TV is getting stuck in a reboot cycle (turns on, shows the Xiaomi logo, turns off and repeats it endlessly).
• 📶 Wi-Fi or Bluetooth is constantly disappearing, the router works properly, and on other devices the connection is stable.
• 🐢 The interface slows down when switching channels, opening apps or settings - even after cleaning the cache.
• 🔒 Forgot the password from parental control or Mi Account linked to the TV.
• 📺 After the firmware update, artifacts appeared on the screen, the sound disappeared or the ports stopped working. HDMI.

If the problem is hardware-related (e.g., broken pixels, physical damage to the matrix, or a broken connector), resetting the settings won't help, and in such cases repairs are required at the service center.

⚠️ Note: On Xiaomi PatchWall TVs (released before 2020), a menu reset may not work due to a bug in the system. If the TV does not restart after the procedure or errors remain, use the method with buttons on the case (section 3).

2.Reset preparation: what to save and how to avoid mistakes

Resetting removes all user data, including:

• 📁 Installed apps (including Netflix, YouTube, IVI etc.).
• 🔐 Linked accounts (Google, Mi Account, social networks).
• 📡 Wi-Fi, Bluetooth and network passwords.
• 🎯 Individual image parameters (brightness, contrast, color profile).
• 🔊 Sound profiles (equalizer, speaker balance).

To avoid resetting everything, follow these steps before resetting:

Take a picture of the current screen settings (the "Picture" section in the menu)

Record passwords from Wi-Fi and linked accounts

Delete important files from internal memory (if any)

Untie the TV from the Mi Account (Settings → Account → Sign out)

-->

If you use external devices (a Xiaomi Mi Box, a game console, or a sound bar), disconnect them from HDMI/ARC ports before resetting. In rare cases, they may conflict with the system during the procedure.

💡

If the TV is connected to the smart home via Mi Home, untie it in the app before resetting, and after the procedure, you have to re-introduce the device into the ecosystem.

Method 3: Reset via the settings menu (for Android TV and PatchWall)

This is the easiest method, but it only works if the TV is turned on and reacts to the remote. Instructions are suitable for Mi TV 4S (2020-2023), Mi TV Q1/Q2 and others based on Android TV 9.0+.

For PatchWall TVs (old firmware):

1. Open Settings → Additional → Recovery and Reset.
2. Select Reset and confirm by clicking OK.
3. If the system requests a password, try 0000, 1111, or 1234.

Method 2: Hardware reset buttons on the body (if the TV is not turned on)

4. If you have a menu (in English), select Wipe data/factory reset using the Volume +/- buttons and confirm Power.
5. After reset, select Reboot system now.

On some models (e.g. Mi TV 4S 55), instead of the recovery menu, you will automatically reset with a reset, and if the screen is black for more than 5 minutes, repeat the procedure or check the power cable.

⚠️ Note: On Xiaomi TVs with OLED-In the matrix (Pro series), frequent hardware resets can cause pixels to burn out due to sudden voltage changes.

5. Method 3: Reset via service menu (for power users)

This method is suitable if the standard methods have failed and the TV is turned on but not responsive to reset, and requires access to a service menu that is hidden from ordinary users.

Instructions:

1. Turn on the TV and on the remote press sequentially: Settings → Up. → Up. → Down. → Down. → Left. → Right. → Left. → Right. → OK (Conami code for logging into the engineering menu).
2. In the menu that opens, select Factory Reset (use the Volume buttons for navigation).

4. The TV will restart automatically.

If the code doesn’t work, try an alternative combination for PatchWall:

Menu → 1 → 3 → 7 → 9 → Menu

⚠️ Warning: In the service menu, you can accidentally change the settings that affect the performance of the matrix or sound!

💡

The service menu is for service center professionals, and if you are not sure about your actions, use standard reset methods (sections 3-4).

6 Possible Errors After Resetting and How to Correct Them

In 10 to 15 percent of cases, after a reset, there are problems, and here are the most common ways to fix them:

1. Connect the flash drive to the TV.
2. Go to Settings → Memory → External device.
3. If the TV detects backups (e.g. screenshots of settings), follow the factory reset.

adb backup -apk -shared -all -f backup.ab
