Modern smart TVs require regular software maintenance to keep up with and access new features. Updating the firmware on Xiaomi 32-inch models is not just a whim, but a necessity to fix bugs and improve interface speed. Users often face a situation where the system stops displaying content correctly or applications start to fly out, and in 90% of cases this is solved by installing the current version of MIUI TV.
The process of software modernization can take place in two main ways: automatically through the built-in interface or manually using the software. USB-The choice of method depends on the current state of your device and the availability of a stable connection to the network. TV 4A or 4S 32-inch versions have a similar architecture, so the instructions will be universal for the entire line of budget models of the brand.
It is important to understand that interrupting the process of writing system files can lead to serious consequences, up to the complete failure of the device. Therefore, before starting any manipulations, you need to carefully study all the steps of the procedure. In this article, we will discuss each step in detail so that you can safely update the software of your TV.
Preparation for the installation of a new version of the software
Before you start the active flashing, you should perform a number of preparatory steps, which ensures that the process will go smoothly and your data will remain safe. Backing up the settings and channel lists is the first thing to take care of, since resetting the system is often part of the update process.
Make sure your TV is connected to a stable Wi-Fi network or has a wired connection via Ethernet.Unstable internet can cause a damaged data packet to download, causing an error when checking file integrity. Also check for free space in the device's internal memory, although the upgrade process itself usually requires a bit of space.
⚠️ Warning: Do not proceed with the update if your network has frequent power surges or planned power outages are possible.Abrupt power loss during recording system sectors is fatal for the controller.
If you plan to use the method with a flash drive, you will need to USB-device with a capacity of not more than 32 GB. Large amounts of memory some models of TVs may not correctly recognize in boot mode. FAT32, This is the most compatible standard for Android embedded media players. TV.

Before updating, take a picture of your current network settings and images on your phone – this will help you quickly restore them after a system reset.
Automatic updates via Wi-Fi
The easiest and safest way to upgrade is to use the built-in OTA (Over-The-Air) mechanism, which allows the TV to find the manufacturer's servers, download the current package and install it, so you don't have to search for files on third-party resources, which minimizes the risk of malware infection.
To start the process, go to the main menu and select the settings section. Usually the path is: Settings → About TV → System Update. In some versions of the PatchWall shell, the menu may be hidden in the "About Device" subsection. Press the check button and the system will contact the server.
If a new version is found, a notice will appear on the screen describing the changes and the file size. You agree to download and wait for the process to be completed. After downloading, the TV will suggest restarting to install updates. At this point, the screen can go out for a few minutes, which is a normal reaction of the system.
- 📶 Make sure the Wi-Fi signal is strong enough, preferably not lower. 2-3 divisional.
- 🔋 Do not turn off the TV with the remote control while booting, even if the process seems to be hanging.
- 🔄 Once installed, the system can take a long time to boot, performing application optimization.
Automation is ideal for those who don't want to know the technical details, but if the servers are overloaded or your model is no longer officially supported by the manufacturer, it may not work, so you'll have to move on to a more sophisticated but reliable method using an external drive.

Automatic updates over the Internet are the safest way, but they require a stable connection and free storage in the internal storage.
Manual installation of firmware through USB-accumulator
When automated search doesn’t produce results or a version on a server older than the one you need, you have to use a manual method.This requires first finding the correct firmware file on the official website or verified forums. The processor model and the exact name of the TV model (for example, L32M5-AS) are critical.
The downloaded file usually has a.zip extension and weighs between 500 MB and 1.5 GB. USB-It is not recommended to change the file name so that the system bootloader can correctly identify it. USB-TV port, preferably in the black version 2.0 connector.
☑️ Preparation for manual installation
You then have to go to the engineering menu or the recovery menu, and often you have to press the power button on the TV body (not the remote) and hold it, turn the device on to the network, and the Recovery Mode menu will appear on the screen, where you can select the Apply update from USB using the volume buttons on the remote (or the buttons on the body).
⚠️ Warning: Installing firmware from another TV model (even with a similar name) will result in a "brick" of the device. Always check the model code on the sticker on the back of the case.
Once the file is selected, the verification process will begin. If the file is corrupted or not fit, the system will issue an error and refuse to continue. Successful installation will end with the message Update from USB complete, then select Reboot system now.
Compatibility table and firmware versions
Understanding the differences between software versions helps avoid errors when choosing a file to download. Below is a table showing the typical differences between global and localized firmware versions for 32-inch models.
| Type of firmware | Region | Google Play availability | Languages |
|---|---|---|---|
| Global ROM | International | There is. | Multilingual |
| Indian ROM | India | Got (often) | English, Hindi |
| China ROM | China | No (Chinese services only) | Chinese, English |
| EEA ROM | Europe | There is. | European languages |
When choosing a file, focus on the region of your device purchase. If you try to install Chinese firmware on a global version, the TV can block the installation or stop working with familiar applications. Regional binding is an important aspect of the Xiaomi ecosystem.
It is also worth considering that switching from one version to another (for example, from Android 9 to Android 11) may require intermediate steps. Direct updates through multiple versions sometimes cause driver conflicts.
Solving errors during the update
Even if all instructions are followed, technical failures can occur, and one of the most common problems is the “No command” message or the endless Mi logo when booting, which often indicates damage to the system partition or a lack of space for temporary files.
If the update is stuck at a certain percentage (e.g. 99%) for more than 30 minutes, a forced reboot. To do this, disconnect the TV from the network for 1-2 minutes, then turn it on again. If the system boots, try clearing the app cache before you try again.
In cases where the TV goes into a cyclic reboot (bootloop), you may need to enter Fastboot mode or use console commands via ADB. This is a more complex method, requiring the TV to be connected to the computer via a USB-TypeA to USB-TypeA cable (or regular USB, depending on the model).
- 🛑 Update failed error: check firmware file integrity and flash drive format.
- 📉 Slow work after the upgrade: perform reset to factory settings.
- 📡 Wi-Fi Disappearance: Driver Incompatibility, Requires a rollback of the version.
⚠️ Warning: If the TV stops responding to the remote and body buttons after a failed update, the bootloader is likely damaged.
Sometimes the problem is not the file itself, but the USB port. Try moving the drive to another connector. Some ports may not give enough voltage to keep the flash drive running while actively reading data.
Resetting settings after system update
After successful installation of the new version of the software, it is strongly recommended to perform a full reset, which allows you to clear the residual files from the old system and avoid configuration conflicts. Factory Reset returns the TV to the "out of the box" state, removing all user data.
To perform the reset, go to Settings → Device → Reset. If the menu is unavailable due to errors, you can use a button combination in recovery mode. Remember that after that you will have to reconfigure Wi-Fi, log into Google accounts and install the necessary applications.
Why do I need to reset after the update?
The first run after reset may take longer than usual, the system will index files and check for updates for embedded applications. Don't interrupt this process, let the TV complete initialization.
In conclusion, regular updates are key to the long life of your equipment. New versions often contain security patches that close vulnerabilities that hackers could use to access your home network. Keep an eye on the manufacturer's news and keep the software up to date.
💡
Complete resetting of settings after updating the firmware is a mandatory procedure to ensure the stability of the new version of the system and remove old configuration files.
