Automatic Internet Update (OTA)
The easiest and safest way to get a new version of software is to use the built-in OTA (Over-The-Air) mechanism, which does not require a computer or a flash drive, everything happens directly on the TV, the main condition is the presence of stable high-speed connection to the network.
Once you click the update check button on the menu and the system finds a new version, the download starts. The speed depends on your Internet channel and the load of Xiaomi servers. At this time, the screen may go out or display the brand logo. Don't try to switch channels or go to the menu.
When the file is downloaded, the TV will ask you to confirm the installation, the process of unpacking and replacing system files will begin after the confirmation, the screen will go out, and the progress indicator may appear. The whole process takes from 5 to 15 minutes. Upon completion, the Xiaomi Mi TV 4S will automatically restart with the new version of Android.
⚠️ Warning: If the download is interrupted due to a power surge or a network break, don't panic. Wait for the router and electricity to turn on, then run the update check again.
In some cases, automatic updates may not start because of a crowded cache. Try clearing the System Update app cache in the application settings section, then try again. This often helps to push back the stuck verification process.
💡
Use an Ethernet cable instead of Wi-Fi to download large updates.The wired connection provides more stable speeds and reduces the risk of file damage when signal jumps.
Manual installation of firmware through USB-accumulator
If the automatic method doesn't work, or if the TV doesn't see the network at all, you have to manually install it, USB-flash drive (preferably up to 32 GB) and archiver. the firmware file should be searched only on official resources or trusted forums specializing in Xiaomi equipment.
The downloaded file (usually with the.zip extension) must be renamed to update.zip (Sometimes you need the exact name on the firmware description and you need to put it in the root of the flash drive. Don't put it in folders, or the TV won't find it. USB-TV port (it is better to use the port) USB 2.0 black).
To start the process manually, you may need to log in to Recovery Mode. On Xiaomi remotes, this is often done by a combination of buttons or through a special menu. In some cases, simply insert a flash drive, go to the update menu and select an Update from USB. If the file is compatible, the system will prompt you to start installing.

What if the TV says "file not found"?
Possible mistakes and ways to solve them
Even if all instructions are followed, there can be unexpected situations, and one of the common problems is a file integrity check error, which can mean that the file has been downloaded with errors or damaged when written to a flash drive. In this case, it is worth restarting the router, downloading the firmware from another source and replacing it. USB-accumulator.
Another common problem is “cyclical reboot” after upgrading. If the TV is constantly turned on and off, it may be that the new firmware version conflicts with the data of old applications. In this case, a full reset to the factory settings (Hard Reset) helps. On the Xiaomi Mi TV 4S, this can be done through a menu or a combination of buttons on the back.
If the sound is gone or the image is pale after the update, don't rush to bring the TV to the service. Often, just reset the image settings to standard or switch the region in the system settings. New versions of MIUI TV can change the image processing algorithms, requiring recalibration.
⚠️ Attention: If the TV stopped turning on after manual firmware (only the indicator or black screen burns), the integrity of the bootloader may be violated. UART-A console that is only made in a service center.
Slow interfaces after updating are temporary, and the system indexes files and optimizes application databases in the background, and let the TV run for about an hour on, and the speed should recover.
