How to Switch Xiaomi TV: Official and Alternative Methods

Xiaomi’s Chinese TVs (Mi TV 4/4A/4S/5/5 Pro, Redmi Smart TV, and others) often come with localized firmware for the Asian market, which creates problems with language, pre-installed services and regional restrictions. The firmware of such a device can solve these issues, but requires caution: improper actions lead to “bricking” (complete failure) or loss of warranty. In this guide, we will analyze all the current methods of firmware – from official updates over the Internet to manual installation of custom versions via USB.

It is important to understand that Chinese firmware differs from global versions. For example, TVs for the Chinese market often block firmware installation from European or Indian versions due to differences in hardware (Amlogic chips, MediaTek) and panel drivers. We will focus on the safe methods that have been tested on 2018-2026 models and warn about the risks associated with unofficial builds.

Preparation for firmware: what you need to know before you start

Before you start upgrading, determine the exact model of your TV and the current firmware version. This information is critical: the firmware from the Mi TV 4A 32" will not work for the Mi TV 5 Pro 55" even if they look similar.

• 📺 Settings → On TV. → Model (example: L32M6-6ARU or K55R1-MI).
• 🔄 Settings → On TV. → Software version (e.g, MSP5.0.1.230410).
• 🔍 Write down the serial number (on the back sticker or menu) – it may be needed to recover through the service center.

Also prepare:

• 💾 Flash drive. FAT32 Up to 16 GB (it is better to use a new or formatted version).
• 🔌 Uninterruptible Power Supply (UPS) – interrupting the firmware process by 80% or more causes damage to the bootloader that cannot be repaired without the programmer.
• 📡 A stable Internet connection (if you update over the air) or a pre-downloaded firmware file.

⚠️ Note: Firmware from Chinese to global (and vice versa) can lead to loss of features, such as disabling Dolby Vision or Google Play. 4PDA or XDA Developers.

Official ways to update firmware

The safest method is to use Xiaomi’s built-in tools, which regularly release updates that correct errors and add new features.

1. Air Update (OTA)

It's suitable for most users, and the TV itself finds and installs the latest version of the software:

1. Connect your TV to the internet via Wi-Fi or Ethernet cable.
2. Go to Settings → About TV → System Update.
3. Click Check Updates and wait for the search to be completed.
4. If an update is found, confirm the installation and wait for the reboot.

Advantages of the method:

• ✅ Automatic compatibility check.
• ✅ Save all settings and applications.
• ✅ Minimum risk of error.

⚠️ Note: On Chinese models OTA-Updates may be delayed or not available for regions outside China. If the system says "No Updates" but you know the new version is coming, use the manual method.

2 Manual update via USB

If OTA doesn’t work or you want to install a specific firmware version, download the file from Xiaomi’s official website or a trusted source (e.g. miuirom.org).

Download the firmware (.zip) for your model|Format the flash drive into FAT32|Rename the file to update.zip|Place the file in the root of the flash drive (not in the folder)-->

Next:

1. Put the flash drive in. USB-TV port (it is better to use the port) USB 2.0, if there is one).
2. Go to Settings → About TV → System Update → Update via USB.
3. Select the update.zip file and confirm the installation.
4. Wait until the end (the TV will restart 1-2 times).

💡

If the TV can’t see the flash drive, try another one. USB-port or format the drive again using the program SD Formatter (select the option) FORMAT SIZE ADJUSTMENT ON).

Installation of custom firmware: risks and opportunities

Custom (unofficial) firmware allows you to unlock additional functions, for example:

• 🌍 Full localization in Russian/English.
• 📱 Installation of Google Play Store and Google services (often missing in Chinese versions).
• 🎮 Support for gaming consoles (e.g, NVIDIA Shield or Steam Link).
• 🔧 Advanced image settings (color calibration, gamma correction).

There are, however, downsides:

Popular custom firmware for Xiaomi TV:

• 🔹 ATV Custom ROM — Android-based TV Supported by Google Services.
• 🔹 MiTV PatchROM - modified stock firmware with Russification.
• 🔹 LineageOS for TV — open-source firmware with minimalist interface.

In order to install custom firmware, you will need to unlock the bootloader. On some models, this can be done via ADB (Android Debug Bridge), on others, only with a programmer. For detailed instructions, look for thematic forums, since the process is different for different chipsets (Amlogic S905, MediaTek MT5658, etc.).

Solving typical firmware errors

Even if you follow the instructions, you can have a problem, and let's look at the most common problems and how to fix them:

1.The TV doesn't see the firmware file on the flash drive

Causes and solutions:

• 🔌 The flash drive is formatted in NTFS exFAT → reformat in FAT32.
• 📁 The file is in the folder. → carry over update.zip drive-root.
• 🔄 Wrong file name → rename update.zip (register!).
• 💥 Damaged. USB-port → Try another port or flash drive.

2. the firmware is interrupted by 25%, 50% or 75%

This is a critical error, often leading to "bricking."

• ⚡ Power surge → Use the UPS.
• 📶 Unstable Internet connection (with the OTA) → connect to the cable.
• 🔧 Incompatible firmware → Check the model and version of the file.
• 🛠️ Damaged sectors of memory → Renovation is required in the service.

If the TV stops turning on:

1. Shut it off the grid for 10 minutes.
2. Try to start in recovery mode (click Menu + Power on the remote when turned on).
3. If the screen remains black, contact the service (you will need flashing through UART or a programmer).

3. There is no sound or image after the firmware

A common problem when installing custom firmware.

• 🔊 Check the sound settings: Settings → Sound. → Exit → HDMI/ARC.
• 🖥️ Reset the image settings: Settings → Screen. → Reset to factory.
• 🔄 Return to stock firmware (if the problem has appeared after customization).

💡

If the TV turns on after firmware, but only loads to the Xiaomi logo, the /system partition is likely damaged, in which case only flashing through Fastboot or a service center will help.

How to return stock firmware

If after experimenting with custom firmware, the TV began to work unstable or you want to return the warranty, install the official software.

1. Download stock firmware for your model from Xiaomi Support or miuirom.org.
2. Rename the file to update.zip and place it on a formatted flash drive.
3. Press the Menu + Back buttons on the remote and hold them, connect the TV to the network. Wait for the recovery menu to appear.
4. Select the Apply update from USB and specify the path to the file.
5. Once completed, reset to factory settings (Wipe data/factory reset).

If the recovery menu is not available, use Fastboot:

1. Connect the TV to your PC via USB.
2. Run the command: fastboot flash recovery.img fastboot flash boot.img fastboot flash system.img (.img files must be from unpacked stock firmware).
3. Reboot the TV with the command fastboot reboot.

⚠️ Note: On some models (e.g. Mi) TV 5 Pro with MediaTek chip MT9611) Fastboot requires authorization through a Xiaomi account. If the TV is not recognized by the fastboot device team, check the drivers or use another cable.

Firmware through the programmer: an extreme case

If the TV is completely brick-and-brick (not responsive to the remote, not on, not determined by ADB/Fastboot), the only way to do this is to run the firmware through the programmer.

• 🔧 Programmer CH341A or RT809H (for working with eMMC flash memory).
• 💻 Software: Flash Tool, eMMC Tool or MiFlash.
• 📄 Firmware dump for your model (can be found on forums or made from a working TV).
• 🔨 Soldering skills (you need to connect to flash memory contacts on the board).

Procedure:

1. Take apart the TV and find a flash memory chip (usually labeled as Samsung KLMxG, Hynix H26M, etc.).
2. Connect the programmer to the CLK, CMD, DAT0, VCC, GND contacts (the connection scheme depends on the chip model).
3. Count the current memory dump and save it (in case of errors).
4. Record a new firmware dump using the Flash Tool program.
5. Get your TV set and check its performance.

This is a risky and skill-intensive method, and a recording error can permanently incapacitate the memory controller, and if you're not sure about your skills, you can contact a dedicated service.

💡

Before running through the programmer, be sure to check the power voltage of the memory chip (usually 3.3V or 1.8V). Connecting the programmer with the wrong voltage will cause the chip to fail.
