Modern Xiaomi Mi TVs and Redmi TVs are built on the Android operating system, which provides extensive functionality, but sometimes leads to software failures. Users can face situations when the interface freezes, applications stop running, or the device stops responding to remote commands. In such cases, a standard reboot is often powerless, and the only way out is a complete flashing of the device.
Software recovery requires carefulness and a strict sequence of actions. Mistakes at any stage can lead to the TV becoming a brick, the restoration of which will require the intervention of the service center using special equipment. It is important to understand that firmware is not just an update, but a complete replacement of the system files that control the operation of the hardware.
In this guide, we will analyze all available ways of reinstallation of the software: from regular updates through the menu to forced installation through the USB-You'll learn how to properly prepare files, how to enter Recovery mode, and what to do if the screen is black. For models up to 43 inches, one version of firmware is often used, and for 50-inch and up, a completely different version, despite the same model name. Ignoring this fact can lead to the inoperability of the matrix.
Diagnosis and preparation for reflashing
Before you start to act, you need to make sure that the problem is in the software, not the hardware. If the TV makes a sound, but the screen is black, or it hangs endlessly on the Mi logo, the likelihood of needing to flash it is high. However, first, you should rule out the trivial reasons: check the remote, power cables and try to perform a full reset through the menu, if it is available.
The key step is to find and download the correct firmware file. Official files are distributed through Mi Upgrade service or specialized forums. You need to know the exact model of your device, which can be found on the sticker on the back of the case. The serial number and the board model (for example, ST32J01 or CV320H) are the data that you will need first.
You will need to carry out the procedure USB-storage capacity up to 32 GB (preferably) USB 2.0) and computer: the flash drive must be formatted into the file system FAT32. This is a critical point: file systems NTFS or exFAT, the TV bootloader may not recognize and the installation process simply won’t start.
Where to download the right firmware for Xiaomi TV
The official Xiaomi website does not always contain direct download links for all models, especially for global versions released several years ago. Often files have to be searched on specialized resources such as 4PDA or Xiaomi Firmware. The main rule of security is not to download files from dubious sites offering “accelerated” versions.
A firmware file usually has a.bin or.zip extension and weighs between 800 MB and 2 GB. When downloading, pay attention to the release date and Android version. Installing an older version on top of a new (downgrade) can be blocked by the bootloader's security system.
⚠️ Note: Using firmware from another TV model is guaranteed to bring the device down, even if the models are called the same (e.g. Mi). TV 4A), There may be different matrices and processors inside.
Once you download the archive, you have to unpack it, and inside you'll find a file with a name that contains the model name and version, for example. MIUSER_..._ST32J01_...bin. This is the file that you're going to have to put in the root of the flash drive. No folders need to be created, the file needs to be on top».
Method 1: Update via the settings menu
If the TV's operating system is stable and you can get into the main menu, the easiest way to use the built-in update mechanism is the most secure method for beginners, since the system will check the integrity of the file before installing it. To do this, copy the firmware file to the flash drive and paste it into USB-television-port.
Next, go to the Settings section. → About the device → System Update: Some versions of PatchWall or Android TV The path may be different. Select the option "Update with" USB-"Drive" or similar. The system will detect the file and suggest starting the process.
- 📺 The TV will automatically check the compatibility of the version.
- 📂 The system will copy the necessary files to temporary storage.
- 🔄 After the check, the reboot and installation of updates will begin.
During the process, the screen may go out and light up several times. Don't pull the power cord out or remove the USB drive until the desktop appears. If the process has been stuck on the logo for more than 15 minutes, it may be that the file is damaged or not suitable for your board revision.
☑️ Pre-installing check
Method 2: Forced installation via Recovery Mode
When the TV doesn't load to the end or the menu isn't available, the forced installation method is used. It requires physical interaction with the control buttons on the device body, since the remote may not work at this point. On different Xiaomi and Redmi models, the button combinations may differ.
The most common method is to disconnect the TV from the network with a button on the case (do not pull the cord if you have a Power button). Press the joystick button (or power button) and, without letting go, turn the TV into the socket. Hold the button until the Mi logo or Recovery menu appears.
In the Recovery menu, navigation is done by volume buttons (if you have them on the remote or case) or by confirmation button. You need to select Wipe Data (data reset), and then Install from USB or Update from USB. After selecting, the system will start searching for the firmware file on the connected drive.
The sequence of actions in Recovery:
1. Wipe Data -> Wipe All Data (Confirm)
2. Return to Main Menu
3. Connect to WiFi (optional)
4. Install from USB (Select file.bin)This method completely clears the device’s internal memory of user data, applications and settings. System partitions are rewritten clean, which often helps solve the “junk” problems in the file system that cause interface brakes.
Compatibility table and model codes
Different TVs may have the same commercial name, but differ in internal code. Below is a table of correspondence between popular models and their codes, which are displayed in the firmware files. Always check the code before downloading.
| Commercial name | Model code (Part Number) | Diagonal | Type of matrix |
|---|---|---|---|
| Mi TV 4A 32 | L32M5-5ASP / L32M5-5AIN | 32 inches | IPS / VA |
| Mi TV 4A 40 | L40M5-5ASP | 40 inches. | VA |
| Mi TV 4A 43 | L43M5-5ASP / L43M5-5ASV | 43 inches | IPS |
| Mi TV P1 50 | L50M7-RU | 50 inches | VA 4K |
| Redmi TV X50 | L50R7-FU | 50 inches | IPS 4K |
What if the code is not in the table?
Solution: Black Screen and Cyclical Reboot
One of the common problems after a failed firmware is a “bootloop” — a cyclic reboot, where the TV constantly displays the logo and turns off.This can mean that the bootloader is damaged or the versions of components do not match each other.
If the screen is black but there's sound, try the blind method: turn on the TV, wait a minute, then press the switch on the remote. If the sound changes, then the system is working, but it's not feeding the image. This may indicate that the firmware is not compatible with the matrix type. The solution is one - look for the firmware file with another suffix that matches your matrix.
⚠️ Note: If the sound is lost or Wi-Fi is not working after flashing, you probably installed firmware from a region other than yours (for example, CN It requires a complete flashing with the correct version with data cleanup.
In rare cases, when software methods do not help, it is necessary to disassemble the TV and solder the memory chip or use the RT809H programmer. This is a complex hardware repair that is better to trust specialists if you do not have experience with soldering equipment.

Before you start any firmware work, take a picture of the sticker on the back of the TV on your phone, which will help you quickly find the right files on the forum or in the support chat if something goes wrong.

The main guarantee of the success of the flashing is the exact correspondence of the file version (.bin) to the factory code of the model indicated on the case sticker, and not to the commercial name of the series.
To conclude, Xiaomi’s Android TV flashing is a powerful device resuscitation tool. A properly executed procedure can breathe new life into the TV by fixing software bugs and adding new features. However, the risk is high, so always double-check your files before you start surgery.
