Modern smart TVs require regular software maintenance to work smoothly and access new features. Xiaomi Mi TV 4S 65 is a popular device, but over time, the embedded operating system may require updating. Users often face the need to improve interface performance or fix software bugs that interfere with viewing content.
The process of updating the firmware on this diagonal has its own technical nuances that must be considered. Wrong actions can lead to malfunctions in the Android TV or even complete inoperability of the panel. In this article, we will discuss in detail all available methods for installing the new version of the software, preparatory steps and ways to solve common problems.
Owners often wonder if they should upgrade at all if the current system is stable. New versions of code often contain security patches and optimizations for streaming services. Ignoring updates can lead to application incompatibility and reduced system response speed over time.
💡
Before starting any firmware manipulations, be sure to take a picture of the current brightness and color settings on the phone, since after resetting they will have to be reconfigured.
Preparation of the TV for the renewal procedure
Before you start active, you need to make sure that the device is ready to receive new data. Connectivity stability is a critical success factor, especially when downloading large files over the Internet. It is recommended to use a wired Ethernet connection, as it provides a more reliable data channel than Wi-Fi.
Check the free space in the internal memory of the device. System update files can take up a significant amount, and if it is not enough, the installation process will be interrupted at the initial stage. Free up space by removing unused applications or clearing the system cache through the settings menu.
It's also important to make sure that the power is stable and that the power surges don't interrupt the process. If you're using a network filter, check it's working, connect external hard drives or USB-drives that do not contain a firmware file, it is better to temporarily disable so that the system does not try to read data from them.
- 🔌 Check for free storage space (minimum 1 GB).
- 📡 Make sure the internet connection is stable or prepare USB-accumulator.
- 🔋 Make sure the remote is serviceable and has charged batteries.
- 📸 Take a photo of the current image and sound settings for quick recovery.
Automatic Internet Update (OTA)
The easiest and safest way for most users is the Over-The-Air method, which checks for the new version on the manufacturer's servers and offers to download it, and you don't need any other devices than the TV itself and the remote control.
You need to go to the settings menu by selecting Settings → About Device → System Update. If the new version is available, a notification will appear on the screen describing the changes and the file size. Press Update and the process will boot automatically.
⚠️ Note: During downloading and installing the update through OTA It is strictly forbidden to pull the power cord out of the socket, even if the screen is turned off.
The duration of the process depends on the speed of your Internet channel and the file size. On the Xiaomi Mi TV 4S 65 model with 4K resolution, files can weigh more than 1 GB. Once booted, the TV will restart and start installing, which can take 5 to 15 minutes.
💡
The OTA method is preferred for ordinary users, as it eliminates the human factor when choosing a firmware version and minimizes the risk of errors.
Update through USB-storage device)
If the automatic search doesn't find updates or you want to install a specific version of the software, the manual method is used. USB-flash drive with a volume of at least 8 GB. The file system of the drive must be formatted into FAT32 or NTFS.
Download the current firmware file from the official support site or a proven resource. The file usually has a.bin or.zip extension and does not require unpacking. Place it in the root directory of the flash drive without putting it in the folders, otherwise the TV will not be able to detect it.
The path to the file: /update.zip (at the root of the drive)Insert the drive into a USB 2.0 port on your TV. Go to Settings → About device → System Update and click the manual update check button (often a three-dot or arrow icon). The system should find the file on the external media and suggest starting the installation.
- 💾 Use only high-quality flash drives of well-known brands to avoid reading errors.
- 📂 The firmware file should lie at the root of the drive, without renaming.
- 🔌 It is recommended to use ports USB Black color (2.0), they are more stable for firmware.
☑️ Checklist before firmware with USB
Compatibility table and software versions
Understanding version numbering helps determine the relevance of the installed system. Global versions are different from Chinese ones, and reflashing the region can require complex manipulation.
| Android version | Screen resolution | Type of update | Region |
|---|---|---|---|
| Android 9.0 | 3840×2160 (4K) | OTA / USB | Global / RU |
| Android 10.0 | 3840×2160 (4K) | USB (Manual) | Global |
| Patch 2023+ | 3840×2160 (4K) | OTA | All Regions |
| Recovery Mode | 3840×2160 (4K) | USB (Force) | Service |
It is important to pay attention to the region of the device. If you bought a TV designed for the Chinese market, installing global firmware in a standard way can block certain functions or lead to a cyclical reboot. Always check the model on the sticker on the back with the firmware file.
What if the menu version doesn’t change?
Solving errors during the update
There can be errors in the update process, from refusing to download to stuck on the logo. One of the common problems is the message “failed to update” when you reach 99%, which often indicates damage to temporary files or memory shortages.
If the process is stuck in the check or boot phase, try Hard Reset. To do this, turn off the TV from the socket, wait 2-3 minutes, then turn it on again. Also helps to clean the cache through the recovery menu if a standard start is not possible.
⚠️ Warning: If the TV goes into a bootloop after a failed update, don’t try to turn it on repeatedly.
For network-related errors, check date and time settings. Incorrect time may block connection to update servers due to security certificate errors. Set up automatic time synchronization over the Internet.
- ❌ “Not enough space” error: remove apps or clear cache.
- ❌ File is corrupted: download the firmware again from another source.
- ❌ Logo getting stuck: Try running in Safe Mode or reflashing through USB.
Optimizing the system after installation
Once the upgrade is completed successfully, the system can run slower than usual for the first hour, because the background processes are indexing files and optimizing application databases, and don't panic if the interface slows down immediately after it's turned on.
Remove the cache of all major apps, such as YouTube, Netflix or online cinemas. Old temporary files may conflict with the new version of the operating system, causing instability. → Annexes → Application management.
Check the image settings, as the new firmware can reset them to standard values. For the Xiaomi Mi TV 4S 65 model with a 4K matrix, it is important to recalibrate the HDR and noise reduction parameters for the best picture.
💡
Rebooting the TV through a complete disconnection from the network after the upgrade helps to reset the residual currents and complete all the background optimization processes.
