Xiaomi’s modern Smart TVs run on Android TV, which requires regular maintenance to keep things running. Receiving security patches and new features is not just a whim, but a necessity to keep the interface running. Many users ignore notifications, which over time leads to slowing down applications and bugs in the system.
The process of software modernization can occur in two ways: automatically via the Internet or manually using the software. USB-The choice of method depends on the current version of the firmware, the model of your device and the stability of the connection to the network. In some cases, automatic search does not find new versions, and then user intervention is required.
In this article, we will take a detailed look at all the preparation steps, look at the nuances of manual installation and answer questions that arise when failures occur. Proper execution of the sequence of actions ensures that your Mi TV or Redmi TV will work as efficiently as possible. Before starting any manipulations, it is recommended to familiarize yourself with the theoretical part to avoid typical errors.
Preparation of equipment and verification of the current version
The first step is to accurately identify your TV model and the version of the installed software. The information is in the settings menu, which can be accessed through the remote control. Navigating the Android TV menu is intuitive, but requires careful choice of items.
You need to go to Settings, then select About Device or Help. In the list that opens, look for the Version or Assembly line. Write down this data or take a picture of the screen, as you will need it to find the current firmware file on the official website.
It is also important to make sure that there is free space in the internal memory: if the storage is full of applications or files, the system may refuse to install updates, delete unused programs or clear the cache before starting the procedure.
⚠️ Warning: Make sure the TV is connected to an uninterruptible power supply or stable voltage outlet.Abrupt power outage while recording system files can cause permanent damage to the software module.
For manual installation you will need USB-The flash card must be formatted in the file system FAT32 or NTFS. The storage capacity is not critical, but it is recommended to use devices up to 32 GB for maximum compatibility with older TV models.
Automatic updates via Wi-Fi
The easiest and safest way to get a new version of software is to use an inbuilt update mechanism, which will contact Xiaomi’s server and check for new data packets, a method ideal for users who don’t want to know the technical details.
To start the process, go to Settings → Device → System Update. Press Update. If the new version is available, the system will prompt you to download and install it. Depending on the file size, downloading can take anywhere from a few minutes to an hour.
During installation, the screen may go out or display the Android logo. This is normal system behavior. Do not try to turn off the device or switch HDMI inputs during this period.
💡
Use Ethernet cable instead of Wi-Fi to download large updates, as this will significantly speed up the process and reduce the risk of download error.
If the system says it has the latest version installed but you are sure to do so, try resetting the update app cache or checking the date and time in the settings. Incorrect system time can block the connection to the server.
💡
The automatic method is preferred because the system itself checks the compatibility of a particular model with the proposed service pack.
Manual installation of firmware with USB-storage
When the automatic search is not working or the TV is not connected to the Internet, you use the manual installation method, you need a computer or laptop with Internet access, and first find an exact model of your TV on the back of the device or in the documentation.
Visit the official Xiaomi support site or the trusted forums. Download the firmware file that matches your model. The file usually has a.apk extension or is an archive. It is important to download the version that is designed for your region, as global and Chinese firmware are not compatible with each other.
☑️ Checking before installation with USB
Copy the downloaded file to the root USB-Don't put it in folders. Put it in the flash drive. USB-TV port (preferably using the port) USB 2.0 black, if you have a choice. Turn on the TV.
The system should automatically detect the update file and prompt the process to begin. If this does not happen, use a file manager (for example, File Commander), find the file on the flash drive and run it manually.
⚠️ Warning: It is strictly forbidden to interrupt the upgrade process, even if the TV is stuck on the logo for more than 10 minutes".
Once the installation is complete, the TV will restart, and the first run may take longer than usual, as applications and system libraries are optimized.
Search and download of current versions of the software
Finding the right firmware is the most important step in manual installation. A file error can lead to Smart functions or a complete system failure. The manufacturer's official website is the most reliable source, but there are not always all versions.
When searching, pay attention to the following parameters:
- 📺 Matrix model and board (indicated on the sticker at the back).
- 🌍 Region of Version (Global, EU, CN, RU).
- 📅 Firmware release date (select the freshest one).
- 💾 File size (should correspond to the description).
There are specialized resources where enthusiasts put up dumps of firmware, use them only if you have experience in flashing electronics, for the average user, the risk of downloading a modified or malicious version is too great.
Often, users confuse versions for Mi Box and TVs, and these devices have different hardware architectures, and the firmware from the consoles is not suitable for TVs, even if the brands are the same.
What is the difference between Chinese and global firmware?
Checking the checksum (MD5 or SHA) of the downloaded file will ensure the integrity of the data. If the amount does not match the amount indicated on the site, the file is corrupted during download and can not be used.
Comparison of Update Methods and Their Features
Each method has its advantages and disadvantages, and the choice depends on the specific situation: Internet speed, technical literacy of the user and the goals of updating.
| Parameter | OTA (Online) | USB (Locally) | ADB (For experts) |
|---|---|---|---|
| Difficulty | Low. | Medium | Tall. |
| Speed. | Depends on the network. | Tall. | Medium |
| Risk of error | Minimum | Medium. | High-pitched |
| Data retention | Yes. | Yeah (usually) | No (reset is often required) |
The OTA (Over-The-Air) method is the preferred method for most users, ensuring that you get the exact version the manufacturer tested for your serial number.
USB is indispensable in the absence of Internet or the need to roll back to an earlier version (downgrade), although the latter is not possible on all models, and modified versions of software are often installed via USB.
Using ADB debugging requires connecting the TV to your computer via a network or cable and typing commands into the console. It's a powerful tool, but one wrong command can delete the system partition.
Common mistakes and ways to solve them
There may be a number of issues during the update process, and understanding the nature of the error will help to quickly resolve the problem without going to the service center, most often with the USB stick file system or the wrong version of the file.
If the TV says "File not found" or "Format error," check the file system of the drive. Android TVs often don't see the exFAT format or Mac file systems (HFS+). Transformat the flash drive into FAT32 computer-based.
The "Not enough space" error is solved by cleaning up the memory: delete heavy applications, games or movies stored in internal memory. System files require temporary space to unpack before installation.
⚠️ Note: If the remote or some buttons stop working after the update, perform a full Factory Reset. Old configuration files may conflict with the new version of the system.
If the TV is stuck on the logo after the update, try to perform a hard reboot, disconnecting the power from the socket for 5-10 minutes. If this does not help, you may need to restore through Recovery mode.
To enter recovery mode, you usually need to press the power button on the TV body (not on the remote) and, holding it, turn the device on to the network. Data/Factory Reset.
