Method 1: Automatic updates via the Internet
The easiest and safest method is an over-the-air update (OTA) that is suitable for most users and does not require technical skills.
To start the process:
- Connect your TV to the Internet (preferably via an Ethernet cable for stability).
- Go to Settings → About TV → System Update.
- Click Check for updates.
- If a new version is available, follow the instructions on the screen.
The update will take 10 to 30 minutes depending on the speed of the Internet and the file size, and the TV will reboot automatically.

Method 2: Manual update through USB-accumulator

Method 3: Update via ADB (for power users)
This is a method that works for those who are familiar with the command line and willing to take risks, and it allows you to install firmware even if the standard methods don't work.
First, turn on ADB debugging on your TV:
- Go to Settings → About TV → The version of the software.
- Click on the version line several times until you have become a developer.
- Return to Settings → Additional → For developers and activate ADB Debugging.
Install ADB Tools on your computer and connect the TV over the network (or via USB-OTG if supported).
adb connect IP_ your TV: 5555
adb shell am start -n com.android.tv.settings/.upgrade.UpgradeActivityAfter that, the TV will open an update menu, where you can select a firmware file from a flash drive or over the network, which requires caution - the wrong commands can disrupt the system.
💡
Use ADB only if other methods have failed, and if you do not do the right thing, you can get a device to blink and you have to restore it through a service center.
Solving Common Errors in Updating
Sometimes the update process is accompanied by errors, and let's look at the most common ones and how to fix them.
| Mistake. | Possible cause | Decision |
|---|---|---|
| No update found. | Xiaomi servers are temporarily unavailable or an update has not yet been released for your region. | Check your internet connection. Try it later or use a manual USB update. |
| File verification error | A damaged firmware file or the wrong name. | Download the firmware again and check the checksum (MD5). Make sure the file has not been renamed. |
| Lack of memory | There is less than 500 MB of free space on the TV. | Remove unnecessary apps or clear the cache through Settings → Storage. |
| The TV will not turn on after the update | Failed firmware or interrupted process. | Reset via Power button + Menu (hold 10 seconds). If it doesn't work, contact the service. |
If none of these methods worked, try resetting your TV to factory settings via Settings → Additional → Reset and Restore. Remember, this will delete all data!
💡
If the sound or image is missing after the update, check the HDMI Output settings (sometimes reset to default values).
Castom firmware: risks and opportunities
Some users install informal firmware (such as LineageOS or modified versions of MIUI TV) to get additional features, but this comes with risks:
- ⚠️ Loss of warranty (if the device is under warranty).
- ⚠️ Unstable operation or compatibility errors.
- ⚠️ Security vulnerabilities (unofficial builds may contain malicious code).
If you do decide to install custom firmware, follow the instructions from trusted forums (for example, XDA Developers). Be sure to back up the current system through adb backup or specialized utilities.
Remember, restoring the original firmware after custom can be difficult, and in some cases, you will need to contact a service center.

How to check the success of the update
After the process is complete, make sure the firmware is installed correctly.
- Go to Settings → About TV → The version of the software.
- Compare the version number to what is listed on Xiaomi’s website for the latest update.
- Check the operation of the main functions: remote, sound, connection to Wi-Fi, application launch.
If the version matches but the TV is unstable (e.g., slowing down or spontaneously restarting), reset to factory settings. This often resolves compatibility issues.
It’s also a good idea to check for new features added in the update, for example, the latest firmware versions for the Mi TV 5 Plus have Dolby Vision support and improved voice management through Google Assistant.
💡
If you have new settings (such as image modes) after the update, check them in the Settings → Picture menu. Often, the manufacturer adds hidden features that are not reported in the changelog.
