How to Reflash Xiaomi TV: A Complete Update Guide

Modern Smart TVs from the brand Xiaomi, running on the operating system Android TV or its own shell PatchWall, require regular software updates for stable operation. Users often face the need to flash when the device starts to work slowly, freezes or stops supporting current versions of applications. Sometimes the new version of the software brings important security features or improves the quality of video decoding.

The firmware update process is not just patching, but a complete rewriting of the system partition. Unlike smartphones, where the procedure is often automated, TVs may require manual intervention, especially if automatic updates over the network do not work. It is important to understand that flashing carries certain risks and needs to be approached prepared so as not to turn a smart screen into a useless piece of plastic.

In this article, we will discuss in detail all the stages: from file preparation to forced installation of the system through the USB-You will learn how to distinguish the global version from the Chinese version, where to look for official files and what to do if the TV stops turning on after the update.

Diagnostics of the current version and preparation for the update

Before downloading any files, you need to accurately determine your device model and current firmware version. The information is usually in the Settings → About TV → Version. Write or take a picture of this data, as the firmware for Xiaomi Mi TV 4A will not work for the Mi TV P1 model, and trying to install an inappropriate file can lead to a brick of the device.

There are two main types of firmware: OTA (air update) and Recovery (full flashing). OTA updates only modified parts of the system, saving user data, whereas Recovery completely clears the memory partitions. If your TV is stable, it is better to use a standard update through the menu. However, if the system is damaged or you want to change the region (for example, from CN to Global), you will need a complete firmware reflash.

⚠️ Warning: Before any manipulations, be sure to disconnect the TV from the power grid for 30 seconds and then turn it on again, which will help to relieve static electricity and avoid false failures in the power controller while recording data.

For a successful procedure, you will need a computer with Internet access and USB-The flash drive must be formatted in the file system. FAT32, The TV loader often doesn’t see the format. NTFS The storage capacity is not critical, but it is recommended to use devices up to 32 GB for maximum compatibility.

Search and preparation of firmware files

The most important step is to find the right file. The official files for different regions and models often differ. For global versions (Global ROM), files usually have the.pkg or.bin extension, while for Chinese versions (CN ROM), the structure may be different. Never use files from unverified forums unless you are sure of their origin.

The downloaded archive needs to be unpacked. Inside, you'll find a firmware file that needs to be put in the root. USB-Don't create folders, the file should be directly in the root directory. You don't need to change the file name, the system will automatically itself when you start the update procedure.

When downloading, pay attention to the checksum of the file, if it is provided by the author, this ensures that the file is downloaded without errors and was not damaged during the transfer. A damaged firmware file is one of the main reasons for unsuccessful updates.

Method of updating via USB-drive

This method is the most reliable, especially if the TV does not have access to the network or a standard update gives an error. USB-TV port, it is recommended to use the port USB 2.0, as it often provides a more stable connection for system operations than 3.0 ports.

Once connected, go to the settings menu. The path may vary slightly depending on the shell version, but it usually looks like this: Settings → About TV → System Update. If automatic search didn't find a file on the flash drive, try using the built-in file manager or Explorer app to find the firmware file and run it manually.

When the system detects the file, the screen will be prompted to confirm the update. Agree and wait. The process can take 5 to 15 minutes. The screen can go out and turn on several times - this is normal behavior. Don't turn off the TV from the outlet at this point, even if it seems to be getting stuck.

⚠️ Warning: If the progress bar is 99% frozen for more than 20 minutes, do not rush to pull the cord. Often at this point, the memory partitions are finalized, and the interruption can damage the bootloader.

Automatic update via OTA (over the network)

The standard Over-The-Air update method is the easiest and most secure for the average user. The system itself checks the servers for a new version of the software. To do this, make sure that the TV is connected to the Internet. Go to Settings → About TV → System Update and click "Check Updates".

If a new version is found, it starts downloading, the speed depends on your Internet connection, and after downloading, the system will suggest restarting for installation. USB-This method is less likely to download an incorrect file, since the server itself determines the model and region of the device.

💡

If OTA-renewal is constantly being broken down 50-60%, Try handing out the Internet from your mobile phone (modem mode). Mobile networks sometimes have less packet loss than congested home Wi-Fi.

However, there are limitations to this method: Xiaomi servers for certain regions (especially CIS) are often updated with a delay, users can wait for a new version of Android or a security patch for months, in such cases, manual method via USB remains the only way to get fresh software.

Solving common errors in firmware

One of the common problems is the "File not found" or "False version" error, which occurs when the firmware file is designed for a different hardware revision of the motherboard, and even if the TV model matches, there may be different matrixes or processors inside, in which case you need to look for a file with the exact match of the version code.

Another common situation is the endless bootloop cycle after an update. If the TV turns on, shows the Android or Mi logo and turns off again, try a factory reset, which often requires you to press the power button on the TV body (not on the remote) and, holding it, turn the device on to the network.

You can also have a situation where the remote is no longer working after the firmware is installed, whether it's reconnected via Bluetooth or using the Mi Remote app on your smartphone to set up the remote for initial configuration, or you need to update the firmware of the remote through the accessory settings menu.

💡

Critical: If after firmware TV stopped responding to the remote, use a smartphone with an infrared port or connect a regular USB-Mouse to the TV to navigate the menu.

Resetting and cleaning the system after the update

After a successful firmware installation, it is recommended to perform a full Factory Reset, which removes the cache of old applications and settings that may conflict with the new system. → General. → Reset.

Remember that after the reset, you will have to reconfigure your Wi-Fi, log into your Google and Netflix accounts, and install the apps you need, but this will ensure that the new system will work as quickly as possible and without the bugs accumulated during the use of the old version.

⚠️ Warning: Data reset will remove all installed apps and logins.Make sure you remember passwords from your accounts before starting the cleanup procedure.

If the TV is slow even after upgrading and resetting, the problem may not be in the software, but in overflowing memory or malfunctioning of the hardware. USB-hub.
