Why it’s important to know the Xiaomi TV version
Determining the firmware version or hardware revision of a Xiaomi TV is not just a technical formality, but a key step to solving most problems. Without this information, it is impossible to find the right firmware to update, diagnose malfunctions or even sell a device with an honest description. For example, Mi TV 4S 2018 and 2020 are superficially identical, but have different motherboards and software versions - installing incompatible firmware can lead to the "bricking" of the device.
Another critical situation is contacting the service center, wizards are denied warranty repairs if the client cannot provide an accurate version of the software, especially if the problem occurs after an independent update. And for enthusiasts who want to unlock ADB or install custom firmware, knowledge of hardware revision (for example, MDZ-22-AA for Mi TV Q1) is a prerequisite.
In this article, we will look at all the current ways to verify versions, from standard menus to hidden engineering teams that work even on locked TVs. TV, Mi TV P1 mi TV Q2, Because their interface is different from the classic lines.
Method 1: Through the main settings menu
The easiest and safest method is to use a standard TV menu, which is suitable for all Xiaomi models released after 2017, including the Mi TV 4A, Mi TV 4X and Redmi Smart TV X. The instructions are versatile, but the path may vary slightly depending on the version of the PatchWall shell.
To get a version of the software:
- Turn on the TV and press the Settings button on the remote.
- Go to Settings → About TV (or About in English).
- Scroll down to Software version, where you will find the current software, such as MIUI TV 2.0.19.0.
- For hardware revision, click on the Model line several times in a row - a hidden menu with detailed information will open.
In some firmware (e.g., Mi TV Q1 75), the path might look like: Settings → System → System Update → Version. If the menu is in English, look for Settings → Device Preferences → About → Software version.
Model number (e.g. L43M6-6ARU)
PatchWall version (Xiaomi shell)
Android TV version (if installed)
Hardware audit (e.g., MDZ-22-AB)
Date of last update-->
Note that on global firmware TVs (e.g. Europe), the software version may be labeled MIUI TV Global, and in Chinese TVs as MIUI TV China, which is important when choosing a file for manual updates.
Method 2: Use of service menu (engineering mode)
If the standard menu doesn't display hardware revision or bootloader version, you can use the hidden engineering menu, which works on most models, but requires caution - wrong actions can lead to a reset.
Instructions for entering the service menu:
- Turn off the TV from the remote (Power button).
- Press and hold the Menu + Volume Down button on the remote.
- Without releasing buttons, press Power on the remote to turn on the TV.
- Hold the combination until the service menu appears (usually 10-15 seconds).
You'll see a few tabs on the engineering menu, and the information you need is in the sections:
- 📋 System Information - software version, motherboard model, serial number.
- 🔧 Hardware Version – Hardware Version (for example, V1.2).
- 🔄 Bootloader Version – bootloader version (critical for firmware via fastboot).
💡
If the service menu doesn't open, try using the Input button instead of the Menu. On some models (Redmi TV A55), the combination may be different.
Note: DO NOT change the settings in the service menu unless you are sure of their purpose. Incorrect settings can lead to loss of image or sound.
Method 3: Through ADB-Teams (for advanced users)
If the TV is connected to the network and you have access to the Android Debug Bridge (ADB), you can get full version information through the command line, which is useful if the screen is not working, but the TV turns on and responds to commands.
To find out the version through ADB:
- Turn on USB debugging in your TV settings: Settings → About TV → Press 7 times on “Software Version” → Return to Settings → Additional → Debugging via USB.
- Connect your TV to your PC via Wi-Fi or Ethernet (USB-TV debugging works over the network).
- Enter in the command line:
adb connect [IP_ address television]:5555
adb shell getprop ro.build.version.incremental
adb shell getprop ro.product.model
adb shell getprop ro.hardwareExample of output for Mi TV P1 55":
MIUI TV 2.0.23.0

mdz22abWhere:
- 📌 MIUI TV 2.0.23.0 - firmware version.
- 📺 L55M6-6ARU — TV-model.
- 🔧 mdz22ab — hardware revision (critical for firmware selection).
How do you know? IP-TV address ADB
This method also allows you to get a full log of the system if the TV is glitching or not turning on.
adb logcat > tv_log.txtMethod 4: On the label on the back panel
If the TV is not turning on or the screen is not working, you can recognize the version by physical marking. On the back of each Xiaomi TV there is a sticker with technical information.
| Parameter | Example of meaning | What does it mean? |
|---|---|---|
| Model | L43M6-6ARU | Model TV (43 inches, 6th revision, for Russia) |
| S/N | G7N2C20111000123 | Serial number (required for warranty) |
| H/W Ver | V1.3 | Hardware revision (Motherboard version) |
| Made in | China/India | Country of production (affects firmware) |
On some models (e.g. Mi TV Q2 75), hardware revisions may be specified in MDZ-XX-XX format, which is critical when ordering parts or selecting a firmware file on forums like 4PDA.
Where to look for the sticker:
- 📍 On the back panel below (near the connectors) HDMI).
- 📍 Under the stand (if the TV is on the leg).
- 📍 In the box (if the documentation is still available).
💡
If the sticker is erased, try to remove the back cover (on a non-working TV) - there is duplicate marking on the motherboard.
Method 5: Through the Mi Home app (for smart TVs)
Xiaomi TVs with Mi Home support (such as Mi TV Master or Redmi Smart TV X2022) can be checked through the mobile app, which is convenient if the remote is lost or the screen does not respond to pressing.
Instructions:
- Install the Mi Home app on your smartphone.
- Add the TV to your device list (if it’s already connected to the same Wi-Fi network as the phone, it’ll show up automatically).
- Go to the TV card and press. ⚙️ Settings → Device information.
- Here will be the firmware version, model and serial number.
If the TV is not displayed in Mi Home, check:
- 🔌 Is TV and phone connected to the same Wi-Fi network.
- 🔄 Is Mi Home Sync enabled in your TV settings (Settings) → Smart home. → Synchronization with Mi Home).
- 📱 Is the Mi Home app updated to the latest version.
On some firmware (e.g., on Mi TV P1 with PatchWall 3.0), the information in Mi Home may not be complete, in which case use method 1 or method 3 (ADB).

Frequent Mistakes and How to Avoid Them
When determining the version of a Xiaomi TV, users often face typical problems, and here are the most common ones and ways to solve them:
⚠️ Warning: If the TV stops turning on after the update, and the red indicator is on the screen - this is a sign of incompatible firmware. Do not try to flash it again without knowing exactly the hardware revision! Contact the service with the model and version of the bootloader (you can find it through the help of the software). ADB, Even if the screen is not working).
Error 1: Hardware revisions are not displayed in the menu
On some models (e.g., the 2019 Mi TV 4S 55) the hardware revision is hidden.
- 🔍 Use method 2 (service menu).
- 🔍 Check the sticker on the back panel (H/W Ver).
- 🔍 Connect to the ADB and run getprop ro.product.hardware.revision.
Error 2: The TV does not respond to the button combination for the service menu
Causes and solutions:
- 🔋 Batteries in the remote control are discharged - replace them.
- 🔄 On some models (Redmi) TV A65) Another combination is used: Menu + Volume Up + Power.
- 🔌 TV connected to the network through a network filter – try to turn it directly into the socket.
Error 3: TV cannot be seen in ADB
This is most often related to:
- 📶 If you don’t have a network connection, make sure that TV and PC are on the same subnet.
- 🔒 Not included debugging by USB — activate it in the settings.
- 🖥️ Lack of drivers ADB On PC – Install Minimal ADB and Fastboot.
