Modern Smart TVs from the Xiaomi brand, running on the Android TV operating system or PatchWall proprietary shell, require regular maintenance of software for stable operation. Updating the firmware is not just a way to get new features, but also a critical procedure to fix security vulnerabilities and fix system errors. Many users ignore system notifications, which can lead to a decrease in interface performance or incorrect application operation.
The process of updating the operating system has become much easier in recent years, but it still raises questions among owners of the equipment. There are two main methods of installing the new version: automatic over the network and manual using the device. USB-The choice of a particular method depends on the current version of the software, the state of the network and the model of your device, whether it is Xiaomi Mi. TV P1 or older series of Mi TV 4A.
In this article, we will discuss in detail all the stages of preparation and implementation of the upgrade to eliminate the risk of turning the TV into a “brick”, you will learn how to properly prepare the media, where to look for official files and what to do if the process stalled or went wrong.
Preparation for the update: important nuances
Before you start any manipulation of system files, you need to make sure that the power supply is stable. Power surges or a sudden blackout of lights while writing data to internal memory can lead to irreversible consequences. If you have the opportunity, connect the TV through an uninterruptible power supply or make sure that the network is not scheduled for work.
The second critical aspect is checking the current version of the software, which will help you understand how serious the update will be and whether you need to download files manually, go to the settings menu and find the About Device section, which displays the build number and the date of the last update.
⚠️ Warning: Don’t try to interrupt the update process even if the screen is gone or an error appears. Interrupting system file writing is almost guaranteed to result in the need to flash through the engineering menu or service center.
It is also worth freeing up space in internal memory if it is filled with applications and cache.The system may refuse to install updates if the free space is less than 500 MB. Remove unused programs or clear the cache through standard cleaning tools.
☑️ Checklist of preparations
Automatic Internet Update (OTA)
The easiest and recommended way is to upgrade the OTA (Over The Air) by itself, to the Xiaomi server, check for a new version and suggest installing it, a method that is ideal for most users, as it eliminates the human factor when downloading files.
To start the procedure, make sure that the TV is connected to the Internet via Wi-Fi or LAN-Then select Settings from the menu, then go to Device and Preferences and find About Device. From the menu that opens, select System Update.
The system will search for available versions. If a new firmware is found, a notification will appear on the screen describing the changes and the size of the file, you will only need to confirm the download and installation, the TV will download the package, check its integrity and restart to complete the process.
💡
Use an Ethernet cable (LAN) instead of Wi-Fi to download large updates, which will ensure a stable speed and reduce the risk of connection failure at a critical time of data writing.
Sometimes the TV says System Updated, even though you know it's coming, and this may be due to regional distribution, so the update will come later when the servers update the database for your region.
💡
Automatic updates are the safest method, as the system itself checks the compatibility of the firmware version with the specific hardware of your TV.
Manual installation of firmware with USB-flash-drive
If the automatic system doesn't work or there's no Internet on the TV, you'll have to use the manual installation method. It's a more complicated way, requiring attention. You'll need a computer with Internet access and a computer with a computer with a computer with a computer with a computer with a computer with a computer with a computer with a computer. USB-storage device of at least 8 GB.
The first step is to determine exactly what your TV model is, and that information is on a sticker on the back of your case or on the device About menu, and it can look like an L32M5-5ARU or an MDZ-16-AA, and a single letter error can lead to incompatible software installation.
Next, you need to find the official firmware file, and it is best to search for it on specialized forums (for example, 4PDA) or on the official support site in the downloads section. The file usually has the.apk extension or is an archive that you need to unpack.
- 📂 Download the firmware file and copy it to the root USB-flash drives (not in the folder).
- 💾 Format the flash drive into the file system FAT32 before-file.
- 🔌 Put the drive in the port. USB 2.0 (usually black) on a working TV.
- 📺 The system must automatically detect the update and prompt it to install it.
If you don't detect it automatically, you can try to manually run the installer through the file manager. Find the downloaded file and run it. The system will request proof of installation rights from unknown sources -- allow this action.
⚠️ Note: The firmware file should be at the root of the flash drive. Creating folders or renaming a system file can make it invisible to the installer of the TV.
Compatibility table and software versions
Understanding the version structure helps determine the relevance of your software, and below is a table of examples of versions for different Xiaomi TV series.
| TV series | Basic OS | Example of a version | Frequency of updates |
|---|---|---|---|
| Mi TV 4A / 4C | Android 9.0 | 3.2.18_20210901 | Rarely (once every 6-12 months) |
| Mi TV P1 43" | Android TV 10 | 1.2.5_20221115 | Average (once in 3-4 months) |
| Mi TV Q1 55" | Android TV 11 | 2.0.1_20230420 | High (once in 2 months) |
| Mi TV Stick | Android TV 9/10 | 1.1.9_20220510 | Irregularly. |
As you can see from the table, new models get updates more often, and older devices can stay on the same version for years, which is normal practice for the budget electronics segment.
Pay attention to the date in the version number (e.g. 20230420 means April 20, 2023) which helps you understand how fresh the file you found online. If the file is dated last year, it may make sense to wait for a newer build.
Solving Common Errors During Updating
The update process is not always smooth, users often encounter a message "Update check error" or "Not enough memory", in the first case, the problem is often an unstable connection to the server or a traffic lock by the provider.
Try to change it. DNS-servers in the settings of the TV network to public, for example, from Google (8.8.8.8) or Cloudflare (1.1.1.1.
If an error occurs when you manually install it, check the integrity of the firmware file. The file may not be fully downloaded or corrupted when you write to a flash drive. Also make sure that the TV model in the firmware file matches yours 100%.
What to do if the TV is stuck on the logo?
In some cases, cleaning the System Update cache helps. Go to Settings → Apps → All apps, find the System Update app, and select Clear Cache and Clear Data.
