Xiaomi Mi TV 1S: official and alternative methods

Xiaomi Mi TV 1S (L32M6-6ARU, L43M6-6ARU, etc.) despite stable work “out of the box” periodically require firmware updates. This may be due to fixing bugs, adding new features (for example, support for Dolby Vision in later versions), or even unlocking hidden features such as Developer Mode. However, the process of flashing TVs based on Android TV is significantly different from the same procedure on smartphones – it is important to take into account the features of the Amlogic hardware platform and the manufacturer’s limitations.

Many users face problems after unsuccessful attempts to update: the TV can hang on the Mi logo, stop recognizing the remote or refuse to turn on altogether. The reasons are the wrong firmware version, interruption of the process or using informal builds without unlocking the bootloader. In this guide, we will examine all the current ways of flashing - from the standard to the standard. OTA-Update to manual restoration through USB Burning Tool, and how to avoid common mistakes and bring the TV back to life if something goes wrong.

Before starting the procedure, make sure that your Xiaomi Mi TV 1S belongs to one of the supported models. The full list can be checked in the settings along the Settings → About TV → Model. Pay special attention to regional firmware - installing the European version on a Chinese TV (and vice versa) can lead to broken services such as Google Play or Mi Home.

1. Preparation for flashing: what you need to know

Reflashing your TV is a riskier process than a similar operation on a smartphone. Unlike Xiaomi Redmi or POCO, where you can always use Fastboot mode, Mi TVs have a closed bootloader by default, which means that installing custom firmware without official unlocking is impossible, and a failed update can lead to the “bricking” of the device.

Before you start, follow the following steps:

• 🔋 Remote battery charge: Make sure the batteries in the remote are charged or replace them. interruption of the process due to a dead remote is one of the most common causes of failures.
• 📡 A stable Internet connection: For OTA-Update requires a speed of at least 10 Mbps. When connecting over Wi-Fi, use the 5 GHz band to minimize interference.
• 💾 Backup: Save a list of installed applications (via Settings) → Apps) and screenshots of screen/sound settings, which can be easily recovered after resetting.
• 🔧 Hand-held firmware tools: Prepare a format flash drive FAT32 up to 16 GB, cable USB-A → USB-A (for PC connection) and the program USB Burning Tool (version 2.2.6 or later).

Critical note: Xiaomi Mi TV 1S on the Amlogic S905Y2 chip does not support unlocking the bootloader through the official Xiaomi service, unlike smartphones.This means that installing unofficial firmware (for example, LineageOS) is impossible without the risk of turning the device into a “brick”.

If you’re planning to upgrade from MIUI TV 1.0 to 2.0+, consider that the new interface may seem less intuitive, lacking the classic Android TV menu, and some features (like HDMI-CEC setup) have moved to other sections.

Method 1: Official Air Update (OTA)

The safest and most recommended method is automatic Internet updates, which are tested for compatibility with iron, so the risk of failure is minimal.

• ⏳ Updates come with a delay (sometimes up to 2-3 months after release).
• 🔄 It is impossible to regress to the previous version.
• 🌍 Regional firmware may block some features (e.g. Netflix in the Internet). 4K Chinese versions).

To check for updates:

1. Open Settings → About TV → Update system.
2. Click Check for updates.
3. If an update is found, confirm the installation and wait for the reboot (it will take 5-15 minutes).

What to do if OTA-update is not available?

1. Restart the TV and router.
2. Check if the updates in Settings → For developers → Auto-update system are disabled.
3. Reset network settings: Settings → Network and Internet → Reset network settings.

💡

If the TV is after OTA-updates started to slow down, try to clear the app cache: Settings → Annexes → Application management → Clear the cache for everyone.

Method 2: Manual update through USB-flash-drive

If OTA is not available or you want to install a specific firmware version, you can use a local update file, which is suitable for recovery from crashes or when you switch between regional versions (for example, from CN to RU).

Step-by-step:

1. Download the firmware from the official Xiaomi Support website. Choose a file with the.zip extension and mark OTA or Full (the latter is preferred for radical changes).
2. Prepare the flash drive: Format it in FAT32 (not exFAT or NTFS!). Copy the firmware file to the root directory (not to the folder!). Rename the file to update.zip (required!).
3. Connect the flash drive to the TV (USB 2.0 port is preferred).
4. Run the update: Go to Settings → About TV → System Update. Select Update via USB. Confirm installation and wait until completion (don't remove the flash drive!).

It takes 10 to 20 minutes. The TV will reboot several times, which is normal. If you have a black screen after the upgrade, wait 5 to 10 minutes, sometimes the first download takes longer.

4. Method 3: Firmware via PC (USB Burning Tool)

This method is required in extreme cases:

• 🔄 The TV does not turn on or hovers on the logo.
• 🔧 You need to “roll back” the firmware to the previous version.
• 🌍 Replacement of the region (e.g., with the IN on EU).

Tools required:

• 🖥️ Windows PC 7/10/11 (on macOS/Linux USB Burning Tool is not working).
• 🔌 Cable USB-A → USB-A (PC-connector).
• 🛠️ Programme USB Burning Tool v2.2.6 and Amlogic drivers.
• 💾 Firmware in.img format (not.zip!).

Step-by-step:

1. Install drivers: Download drivers for Amlogic. Connect the TV to the PC off (hold the power button for 10 seconds to shut down completely). Press the Menu button on the remote and, without letting it go, connect the cable to the TV. The driver must be defined as Amlogic Device.
2. Set up the USB Burning Tool: Run the program on behalf of the administrator. From the File → Import image menu, select the downloaded file.img. Press Start and wait for the green progress bar to appear.
3. Wait until it's finished: It takes 5-10 minutes. The TV will restart automatically when it's finished. If you have a 0x304 or 0x1010 error, repeat the procedure with another firmware version.

⚠️ Note: If the TV is not detected in USB Burning Tool, Try: Use another one USB-port on PC (preferably) USB 2.0). Disable the antivirus (it can block drivers) reinstall the program in a folder without Cyrillic characters (for example, C:\Amlogic\).

5 Unlocking Hidden Functions After Firmware

After a successful update, you can activate additional features that Xiaomi hides by default.

• 🎮 Developer Mode: Go to Settings → About TV and 7 times click on the build number. You will see a menu for developers where you can turn on debugging on USB and Unknown sources.
• 🔊 Advanced sound settings: In the menu Settings → Sound. → Additional may be included HDMI ARC and S/PDIF Connecting external audio systems.
• 🖥️ Change of permission: Through ADB can be enforced 4K@60Hz, If the TV automatically reduces the 1080p. Command: Adb shell wm size 3840x2160

How to enable Dolby Vision on unofficial firmware:

If your Mi TV 1S doesn’t support Dolby Vision out of the box, but is hardware-capable (the Amlogic S905Y2 chip + HDR10+ panel), try the following:

⚠️ Warning: Activating Dolby Vision on unsupported models can cause image artifacts or matrix overheating.Before using, check the back temperature of the TV after 30 minutes of viewing HDR-content.

Typical errors and their solutions

Even when following instructions, users often face problems.

If the TV after firmware began to “glutch” (spontaneous reboots, artifacts on the screen), perform a complete reset:

1. Go to Settings → Device → Reset settings.
2. Select to erase everything (including internal storage).
3. After restarting, set the TV as new.

💡

If Wi-Fi or Bluetooth is missing after the firmware, it is likely that the firmware was installed for another hardware revision, in which case only re-running through the USB Burning Tool with the correct.img file will help.

7. Alternative firmware: risks and opportunities

Xiaomi’s official firmware doesn’t always satisfy users: it may not support Widevine L1 (needs Netflix in 4K), limited access to Google Play or removed some features (e.g. Ambient Mode).

• 🔧 CoreELEC: Lightweight system for media centers (supports Kodi, but loses Smart features) TV).

Risks of using custom firmware:

• 🚫 Loss of warranty (even if the TV is no longer warranty, the service center may refuse to repair the TV).
• 🔌 Non-functioning ports (e.g, HDMI-CEC or ARC).
• 🔋 Increased energy consumption due to unoptimized core.
• 📵 Lack of security updates (vulnerability in Android) TV 9, on the basis of which many custom assemblies work).

⚠️ Note: Installation of CoreELEC or LibreELEC on Xiaomi Mi TV 1S requires unlocking the bootloader through the exploit, which can lead to a complete loss of functionality, 4PDA) There are instructions, but they are designed for experienced users and often contain errors.

If you do decide to experiment, follow the rule: first make a full backup of the current firmware through the USB Burning Tool (Backup option), which will allow you to return the TV to its original state if something goes wrong.
