Modern smart TVs from Xiaomi require regular maintenance of software to work smoothly. Many users face the need to install a new version of the operating system to access fresh features or fix bugs in the application, a process that is not always intuitive, especially if the device no longer automatically receives notifications about the availability of an update.
In this article, we will discuss in detail all the available ways to update Xiaomi Mi TV redmi TV. You will learn about the nuances of automatic installation via Wi-Fi, as well as the manual method using the use of the system. USB-a storage device, which is often the only way out when network connection problems.
It’s worth noting that installing security patches and system improvements on time extends the life of the device, and ignoring updates can cause some streaming services to stop displaying content correctly or stop running on an outdated version of Android TV.
Why You Should Update Your TV Software
The main reason for regular firmware updates is to optimize the work of the hardware, where developers are constantly releasing patches that improve the interaction between the processor, graphics accelerator and video decoding module, which allows the TV to open heavy applications faster and smoothly play content in high resolution.
In addition, new versions of MIUI for TV or PatchWall bring changes to the interface, making navigation more convenient, often adding new widgets, changing the logic of the voice assistant or improving the content search algorithm, without installing the current version of the system, the user deprives himself of these conveniences.
⚠️ Warning: Before starting the procedure, make sure your TV is connected to the power supply network via a regular cable, rather than through an unstable extension cord, to avoid voltage spikes while recording data.
It’s also important to keep security in mind: Older versions of the operating system may contain vulnerabilities that could theoretically allow attackers to access the home network, and regular updates close those holes, ensuring that your personal data and passwords are protected from the Wi-Fi router.
Preparation for the installation of a new version of the firmware
Before you start any manipulation of system files, you need to do a number of preparatory actions, this minimizes the risk of errors and ensures that the process will be successful.
If the memory is busy with games or heavy applications, the installation process may be interrupted, it is recommended to remove unused programs or clear the cache through the settings menu, and it is also worth disabling any external hard drives or flash drives that will not be used for the upgrade.
☑️ Check before updating
Pay special attention to the stability of the Internet connection. If you plan to download the update directly from the TV, make sure that the Wi-Fi signal is strong. 99% interruption of the download can cause damage to system files and the need to flash through the service center.
💡
Before updating, take a picture of the current image and sound settings on the phone - this will help to quickly restore the usual picture, if after the update the settings are reset to the factory.
Automatic Internet Update (OTA)
The simplest and most common way is to update the OTA (Over-The-Air) by contacting the manufacturer's server, checking for a new version and suggesting that it be installed, a method that is ideal for most users, as it does not require additional devices.
To start the process, you need to go to the settings menu. Navigation may vary slightly depending on the shell version, but the general path usually looks like this: Settings → Device → System Update. In some models, the path may be Settings → Help → System Update.
Once you go to the appropriate section, click "Check Updates" button. If a new version is found, the system will prompt you to start downloading, depending on the file size and your Internet speed, this process can take anywhere from 10 minutes to an hour.
💡
Automatic updates via the Internet are the safest way for the average user, as the system will check the compatibility of the firmware version with a particular TV model.
During installation, the screen may go out and the TV may reboot several times, which is normal behavior. Don't try to pull the power cord or press the switch off button until the system desktop appears on the screen.
Manual installation of updates through USB-accumulator
If the automatic search fails or the Internet connection is unstable, you have to use the manual method. USB-USB flash drives with a capacity of at least 8 GB. This method is often called “clean installation”, as it allows you to completely replace system files.
First, you need to find the right firmware. Go to the official Xiaomi support site or authorized forum. You need to download a file that strictly matches the model of your TV. The model can be found on the sticker on the back of the device or in the Settings → About Device menu.
Once a file is uploaded (usually with a.apk extension or a special archive), it must be properly prepared. The flash drive must be formatted into the FAT32 file system. The firmware file must be placed in the root of the flash drive without putting it into folders.
What to do if the TV can’t see the flash drive?
Insert the prepared flash drive into USB-TV port (preferably using the port) USB 2.0, often blue, although it's not always critical. Restart the TV. If the firmware file is correct, the system will detect it and prompt you to start updating it.
Comparison of Update Methods and Possible Problems
Each of these methods has its advantages and disadvantages: the automatic method is convenient, but depends on Xiaomi servers, which can run slowly during peak hours.
Often users experience a “failed to update” error or a process freeze at a certain percentage, which may be caused by a corrupt firmware file or a lack of memory. The table below compares the main characteristics of the methods.
| Characteristics | OTA (Online) | USB (Offline) | ADB (For experts) |
|---|---|---|---|
| Difficulty | Low. | Medium | Tall. |
| I need a PC. | No. | Yes (for download) | Yes. |
| Speed. | Depends on Wi-Fi. | Depends on the flash drive. | Depends on the cable. |
| Risk of error | Minimum | Medium. | High-pitched |
If you have a bug in the manual installation process, don't panic. Try to take a different flash drive or download a firmware file from another source. USB-port of the TV which may be contaminated or defective.
⚠️ Warning: Never interrupt the process of recording data on a TV flash memory. If the indicator flashes or the screen says "Don't turn off the power", wait for completion, even if it takes more than an hour.
