Xiaomi Mi TV 4A remain popular due to its price-to-feature ratio, but over time, its firmware becomes obsolete. Software update solves brake problems, adds new features (such as Dolby Vision support in later versions) and closes security vulnerabilities. However, not all users know that firmware can be performed not only automatically over the Internet, but also manually - even if the TV "blocked" after a failed update.
In this article, you will find the current 2026 methods of flashing Xiaomi TV 4A (including models 32" 43" 50" 55"), as well as solutions to common errors such as logo getting stuck or cyclic reboot. We will analyze the official methods from the manufacturer and alternative options for power users. Importantly, firmware for Chinese (CN) and global (Global) versions of TVs are not interchangeable - installing an inappropriate version will lead to the failure of the device.
Preparation for Flashing: What to Do Before Starting
Before you start upgrading, make sure your Xiaomi 4A TV is ready for the procedure. Neglect of preparation is the main reason for "bricking" devices. Start by checking the current firmware version: go to Settings β About TV β Software version. Write or take a picture of this information - it will be necessary to select the correct update file.
Note the region of the firmware: if your TV was purchased in China (the model ends in CN), you can't install global firmware (Global). The same goes for the reverse situation. To find out the region, look at the sticker on the back of the TV or in the Settings menu β About TV β Model. For example, Mi TV 4A 55" with the L55M5-5AIN marker is the Indian version, and L55M5-5ACN is the Chinese version.
- π Recharge: Make sure the batteries in the remote are charged or replaced. The upgrade process can take up to 30 minutes, and the remote discharge in the middle of the procedure will interrupt it.
- π‘ Stable Internet connection: If you plan to upgrade by air (OTA), Connect the TV to the network via Ethernet cable β this will reduce the risk of connection breakdown.
- β‘ Power supply: Use only the original power supply. Flashing through USB using cheap charging can lead to failure due to unstable voltage.
- πΎ Backup Settings: Save the list of installed apps and personal settings (such as screen calibration) as a reset may be required after the update.
β οΈ Note: If your Xiaomi TV is yours 4A no longer switched on or stuck on the logo, skip this section and go straight to the recovery method through USB (Attempting to update automatically in this state will exacerbate the problem.
Method 1: Automatic Air Update (OTA)
The easiest and safest way is to upgrade over the Internet, which is suitable if the TV is turned on and connected to the network. Xiaomi regularly releases updates for the Mi TV 4A, but they spread in waves: your device may not see the new version immediately after release.
To check for updates:
- Open Settings (cog in the upper right corner of the main screen).
- Go to the section About TV β Updating the system.
- Click Check for updates.
- If an update is found, confirm the installation and wait until it is completed (the TV will restart automatically).
If the system says βNo Updatesβ but you know that the new version is out (for example, on the 4PDA forums or Xiaomi Community discussing the latest release), try the following steps:
- π Restart the TV and check again.
- π Change region in your network settings (e.g. India or Singapore) as updates sometimes appear there earlier.
- π Wait 1-2 days β Xiaomi servers can be overloaded.
β οΈ Attention: If, during OTA-If the TV is switched off (for example, due to a power outage), it may stop turning on. USB (see section 4).
π‘
Automatic updates over the Internet are the safest way to do so, but require a stable network connection and patience: sometimes new versions are only available a week after release.
Method 2: Hand-held firmware through USB-flash-drive
If the automatic update doesnβt work or you want to install a specific version of the firmware (for example, roll back on the old one due to bugs), use the manual method via USB. This method will also help if the TV is stuck on the logo or cyclically rebooting.
To start, download the official firmware from Xiaomi. It is important to choose a file specifically for your model and region. For example, for Mi TV 4A 55" Global, a firmware with a L55M5-5A marker and a Global mark will suit.
- π Official website of Xiaomi (Global)
- π¨π³ Official website of Xiaomi (China)
- π₯ Forum 4PDA (flat-fibre)
Installation instructions:
Format. USB-storage FAT32 (not NTFS!)
Download the firmware and unpack it. ZIP-archive
Rename the update file to update.zip
Place the file in the root of the flash drive (not in the folder!)
Turn off the TV from the network before connecting the flash drive
-->
- Format the flash drive in FAT32 (no more than 32 GB in size).
- Download the archive with firmware unpack and rename the file to update.zip (it is important to follow the register!).
- Place update.zip in the root of the flash drive (not in the folder!).
- Turn off the TV from the socket, insert the flash drive into the USB port (preferably in USB 2.0, if any).
- Press the Menu button on the remote (or on the TV body if the remote is not working) and, holding it, turn the TV on the network.
- In 5-10 seconds, the recovery menu will appear. Select Update and confirm the installation.
- Wait until it's finished (it'll take 10-20 minutes) and the TV will reboot automatically.
If the TV doesnβt turn on after the reboot or the indicator flashes, repeat the procedure with another flash drive (possibly a problem in the drive). Also check that the firmware file is not damaged β its MD5 checksum must match the one listed on the Xiaomi website.

Method 3: Firmware through ADB (for power users)
This is a way for advanced users who want to install custom firmware or debug the TV, which requires a computer with ADB and Fastboot installed, and USB debugging enabled on the TV.
Warning: Incorrect ADB commands can cause the device to fail completely. If you are not sure about your actions, use the first two methods.
To enable USB debugging on Xiaomi TV 4A:
- Go to Settings. β On TV.
- Find the build number and click on it 7 times in a row until the notification βYou became a developerβ appears.
- Go back to the main settings menu and open a new section for developers.
- Activate the USB Debugging options and Allow OEM unlocking.
Next, connect the TV to your computer via USB (use the USB 3.0 port on your TV if you have one) and execute commands in the terminal:
adb devices
adb shell
su
reboot updateAfter the reboot, the TV will go into update mode, and you can install firmware through ADB Sideload:
adb sideload update.zipIf the process freezes, try reconnecting the cable or using another port. Recovery from a failed firmware through ADB may require a service center.

Before using ADB, check that the driver for Xiaomi TV is installed on your computer. These can be downloaded from the Android Studio website or through the Mi PC Suite.
Solving errors after flashing
Even if the firmware is successful, there may be problems, and let's look at the typical scenarios and how to fix them.
| Problem. | Possible cause | Decision |
|---|---|---|
| The TV is not turned on, the red indicator flashes. | Incorrect firmware or interrupted update | Repeat the firmware via USB with the correct update.zip file |
| Cyclical reboot (bootloop) | Data conflict after update | Reset to factory settings via the Recovery Menu (Wipe Data) |
| No sound after firmware. | Resetting audio settings | Check the sound settings in Settings β Sound or reset the settings |
| Apps fly out or don't open | Incompatibility with the new version of the software | Update apps through Google Play or reinstall them |
| The remote is not working. | Resetting a pair of remote control with a TV | Press Home + Back on the remote for 10 seconds to reconnect |
If the TV is unstable after firmware (for example, the interface is slowed down or the image is lost), try:
- π Reset the settings to factory (Settings) β Additionally. β Reset).
- π₯ Reverse to the previous firmware version (if backup is saved).
- π οΈ Update apps manually through Google Play.
β οΈ Note: If after flashing the TV requires activation through Mi Account, but you do not remember the account details associated with the device, recovery may not be possible without contacting the Xiaomi service center (CN) account-bound.
