How to reflash the TV Xiaomi Mi TV: official and alternative ways

Xiaomi Mi TV flashing is a procedure that can solve performance problems, add new features, or even resurrect a device after a crash. However, the wrong actions often lead to a “bricking” (complete failure) of the TV, especially if it is a matter of informal firmware. In this article, we will discuss all the current ways to update software — from standard OTA to manual restoration through ADB — and also describe how to avoid typical errors.

It’s important to understand that Xiaomi regularly releases updates for its TVs, but not all models are supported the same long. For example, the Mi TV 4A (2018) does not receive the latest PatchWall versions, while the Mi TV Q2 2023 is updated monthly. Before you start flashing, check the firmware compatibility with your model – this will save you from unpleasant surprises.

Preparation for reflashing: what you need to know

Before you update the software, follow a few critical steps:

• 📋 You can find the TV model in the Settings menu. → About the TV or the sticker on the back of the case. TV 4S Not good for Mi. TV 5 Pro!
• 🔋 If the remote dies during the process, you can't confirm the actions on the screen. Use the wired mouse in the port. USB backup.
• 🌐 Stable Internet connection. To download firmware through OTA Wi-Fi speed should be at least 5 Mbps. if the signal is weak, download the file to your computer.
• 💾 Backup settings. After the update, you can reset your connected accounts, channel list, and image settings. Take a note or take a picture of your key settings.

If you are planning to downgrade the firmware version (downgrade), consider: Xiaomi blocks this feature on new models through the anti-rollback mechanism. Trying to install the old firmware can lead to a lockdown of the bootloader and the need to contact the service center. Check the list of supported versions on the official Mi Community forum.

⚠️ Note: On Xiaomi TVs with Amlogic processors (e.g. Mi) TV 4X) Incorrect firmware can damage the bootloader, in which case recovery is possible only through the use of a USB Burning Tool with connection to PC.

Method 1: Automatic update over Wi-Fi (OTA)

The easiest and safest method is to upgrade over the air, and Xiaomi releases patches to fix bugs and add features every 1 to 3 months to check for updates:

1. Open the Settings menu → About the TV → System Update.
2. Click Check for updates.
3. If a new version is available, follow the instructions on the screen. The TV will reboot automatically.

Advantages of the method:

• ✅ Does not require technical skills.
• ✅ Minimum risk of failure (firmware checked for compatibility).
• ✅ All settings and data are saved.

Disadvantages:

• ❌ Updates come with a delay (sometimes up to six months for older models).
• ❌ No way to select a specific version of the software.

Automatic updates over the Internet are the safest way, but require a stable connection to the network.

Method 2: Manual update through USB-accumulator

If OTA-Update is not available or you want to install a specific firmware version, use USB-This is a method that works for most Mi models. TV, including Mi TV 4A/4S/4X/5 Pro.

Step-by-step:

1. Download the firmware from the official Xiaomi Firmware Update website. Choose a file with the.zip extension for your model (for example, mibox3_ota_update-1234.zip).
2. Prepare. USB-Driver: Format the flash drive into FAT32 (not NTFS!). Copy the downloaded archive into the root directory (not folders!). Rename the file to update.zip (necessarily!).

Method 3: Firmware through ADB (for power users)

The ADB (Android Debug Bridge) method is suitable for custom firmware or rollbacks when other methods are not working. It requires a PC with drivers installed and USB debugging enabled on the TV.

What you need:

• 🖥️ Computer with Windows/Linux and installed Android SDK Platform Tools.

If you have an E: footer is wrong error, check the integrity of the archive or try again with another firmware.

Castom firmware: risks and opportunities

Xiaomi’s official software doesn’t always suit users: some want to get rid of ads in PatchWall, some want to install Google Play Services to run apps, and custom firmware like:

• 📱 LineageOS – “clean” Android TV superstructureless.
• 🛡️ AOSP — Open source firmware, without advertising.
• ⚡ SuperTV - modified version with advanced image settings.

But there are also serious risks:

• ⚠️ Loss of warranty (if the TV is warranty, Xiaomi will refuse repairs).
• ⚠️ Unstable work (possible lags, application departures, sound problems).
• ⚠️ Block Netflix and Disney+ Due to lack of Widevine certification L1.

Before installing custom firmware:

1. Check compatibility with your model on the 4PDA or XDA Developers forums.
2. Backup your current firmware through ADB: adb backup -apk -obb -shared -all -f backup.ab
3. Make sure the firmware supports OTA-Update, otherwise you will have to manually check each time.

💡

If HDMI has lost audio after installing custom firmware, check the audio output settings in Settings → Sound → Digital Sound (HDMI). Factory resets often help.

Solving Firmware Errors

Even if you follow the instructions, you may have a problem, and let's look at the typical mistakes and how to fix them:

If the TV does not respond to the remote after a failed firmware:

1. Turn off the power for 1 minute, then turn it on again.
2. Connect your keyboard or mouse via USB and try to log in to the Recovery Mode menu.
3. If the screen is black but the light is on, try a blind reset: Press and hold the Power on the remote for 30 seconds. Turn off the power, wait 2 minutes, turn it on again.

⚠️ Note: On Xiaomi TVs with MediaTek processor (e.g. Mi) TV A Pro) incorrect firmware may damage the preloader partition, in which case recovery is possible only with the help of a programmer SP Flash Tool at the service center.

Rebuilding the “Brick” TV

If the TV doesn't turn on, doesn't show a logo, or hangs on a screensaver, don't panic. In 80 percent of cases, the device can be restored.

• 🟢 Soft-brick: The TV turns on but does not load beyond the logo, and is solved by flashing through Recovery or by downloading it. ADB.
• 🔴 Hard-brick: No response to buttons, no black screen, requires a programmer and a physical connection to the board.

Instructions for Soft-Brick:

1. Download the full firmware image (not OTA!) for your model from Xiaomi or 4PDA.
2. Connect the TV to your PC via USB (OTG port or service connector).
3. Use the USB Burning Tool (for Amlogic) or SP Flash Tool (for MediaTek) to write the firmware directly to memory.

References to tools:

• USB Burning Tool (for Amlogic chips)
• SP Flash Tool (for MediaTek chips)

If the TV is not detected by the computer:

• Check if the original cable is used (not all) USB-cables support data transmission).
• Install drivers for Mediatek Preloader or Amlogic USB Device.
• Try to connect in bootloader mode (on some models you need to pin Power + Volume Down when connecting to a PC).
