Modern Smart TV from Xiaomi, which runs on Android TV, They require regular attention from the user, not only to view content, but also to maintain system stability. Over time, software finds bugs that developers fix by releasing security patches and optimized packages. Updating your firmware is not just a way to get new emojis or wallpaper changes, but a critical procedure to ensure the security of your data and the correct operation of applications.
Device owners often face situations where the interface is slower and some apps stop running or give out connection errors. In such cases, a system update is the first and most effective solution to the problem. Ignoring available updates can lead to new versions of popular streaming services simply no longer being supported on your version of the operating system.
The process of upgrading the TV software can take place in two main ways: automatically over the network or manually using the TV. USB-Each method has its own nuances, benefits and risks that you need to know about before starting the procedure. In this article, we will discuss both methods in detail, paying special attention to preparing the device to eliminate the possibility of critical errors in the process of writing new system files.
Preparation of the TV for the installation of a new version of the software
Before you start downloading and installing files directly, you need to make sure that your device is ready for this procedure. Power stability is the most important factor, since a sudden power outage during recording system sectors can lead to irreversible damage to the software module.
The second important aspect is checking for free space in the internal memory of the device. System update files can take up a significant amount of space, and if the storage is full of application cache or personal files, the process can be interrupted during the verification stage. Clear unnecessary data or remove rarely used applications through the settings menu to free up at least 1-2 GB of space.
⚠️ Warning: Do not attempt to interrupt the upgrade process even if the screen is out or the TV appears to be getting stuck.A forced power out at this point can turn the device into a "brick", the restoration of which will require complex hardware flashing.
It is also worth checking the status of your Internet connection if you plan to use the OTA (Over-The-Air) method. To download large data packets requires a stable communication channel without frequent interruptions. If the Wi-Fi signal is weak, it is better to use a wired connection via an Ethernet port or temporarily move the router closer to the TV.
💡
Before all procedures start, take a picture of the screen with the current image and sound settings on the phone. After updating, some parameters can be reset to factory ones, and the photo will help you quickly return to your usual calibration.
Automatic Network Update (OTA method)
The easiest and safest way to update the system is to use a built-in update mechanism, which does not require a computer or flash drive, since all the necessary actions are performed by the TV itself.
To start the process, you need to go to the main menu and find the settings section. The path may vary slightly depending on the version of the PatchWall shell or pure Android TV, but the logic remains the same. You usually need to select the "About device" or "System" item, where the check button is located.
If the server detects an available version, a notification will appear on the screen describing the changes and the file size. If you agree to the terms, you will start the download, the progress of which will be displayed as a percentage.
- 📡 Go to Settings. → About the device → System Update to Start Verification.
- 📥 Wait for the package to load without turning off the TV or running heavy apps.
- 🔄 Click the Reboot button when the system requests installation confirmation.
- ⏳ Once turned on, the TV can further update components in the background, which will take a few minutes.
It's important to understand that automatic updates may not come immediately after release. The company often distributes new versions in stages, so the update can appear on different devices of the same model with a difference of several days or weeks. If you want to speed up the process, you can try to clear the cache of the system application updates, but this requires a deeper dive into the settings.
💡
The automatic method through OTA is preferred by most users, as it minimizes the risk of human error and guarantees the installation of a certified version of the software.
Manual installation of firmware through USB-accumulator
In situations where automatic updates don't come in, or the Internet connection isn't stable enough to download large amounts of data, you have to resort to the manual method. USB-flash drives with a volume of at least 8 GB. The file system of the drive must be formatted into FAT32, as file systems NTFS or exFAT may not be recognized by the TV bootloader.
The first step is to find the official firmware for your particular model. It is important not to confuse the versions, as installing the wrong software can lead to incompatibility of the display drivers or Wi-Fi module. Information about the exact model can be found on the sticker on the back of the device or in the menu "About the device".
Once you download the firmware archive, you have to unpack it, and it's usually a file with the.bin extension or a folder with a name on it. mi_tv_upgrade. This file or folder should be copied to the root. USB-The TV scans only the root directory when the update process starts.
☑️ Checklist for manual installation
⚠️ Warning: Make sure that the downloaded firmware is designed for your region (Global, China, Russia).Attempting to install Chinese firmware on the global version (or vice versa) without proper preparation will lead to a lockdown of the bootloader.
To start the process, insert the prepared flash drive into USB-Then, through the settings menu, find the item "Update through" USB» If you don't automatically start, you can try to find the installer through the file manager, but the standard way through the settings is more reliable.
Once the installation is confirmed, the screen will go out, and the Android or Mi logo with a progress lane may appear, at which point it is strictly forbidden to remove the drive or turn off the power, the process can take from 5 to 15 minutes depending on the volume of changes and the speed of recording.
Upgrade methods comparison: OTA vs USB
The choice between automatic and manual updates often depends on the specific situation and the technical literacy of the user. Each method has its own strengths and weaknesses, which should be considered before starting the procedure.
| Criteria | OTA (Through the Network) | USB (Manually) |
|---|---|---|
| Difficulty | Minimum (automatically) | Medium (requires PC and flash drives) |
| Speed. | Depends on the Internet. | Depends on the speed of the flash drive. |
| Risk of error | Low. | Medium (human factor) |
| Relevance | He's late. | You can install it immediately after release. |
Automated is ideal for those who don’t want to know the technical details and are willing to wait until the update reaches their device, a safe option that eliminates the risk of downloading an infected file or confusing the version, but if the TV has stopped working properly and needs an urgent patch, waiting can be unacceptable.
The manual USB method gives you complete control over the process and allows you to install a specific version of the software, for example, to roll back to an older version if a new one contains bugs, which is the choice of experienced users who understand how the file system works and know how to check the integrity of the downloaded data.
What to do if the TV can’t see the flash drive?
Common mistakes and ways to solve them
Even with careful follow-up, unexpected situations can occur. One of the most common problems is the message “Update error” or an endless reboot cycle. Often this involves corrupting the firmware file when downloaded or writing to a faulty sector. USB-storage.
If the process is stuck at a certain percentage, don't panic right away. Sometimes the system performs background optimization of databases, which can take considerable time. 30 You might need to force the device to reboot in a few minutes. 1-2 minutes and then turn it on again.
- ❌ Lack of memory: Clear the app cache or delete excess files before starting.
- ❌ Unstable Wi-Fi: When the connection breaks, the download will be interrupted, use an Ethernet cable.
- ❌ Wrong model: Check the exact model name on the back sticker.
In some cases, the antivirus on the computer can block or modify the firmware file, considering it suspicious because of the signatures of the system code. Before writing to the flash drive, it is recommended to temporarily disable the security software or add the file to exceptions.
⚠️ Note: If the TV stops turning on Wi-Fi or Bluetooth after the update, this can mean a driver conflict.
