How to Upgrade Xiaomi 32-inch TV: 3 Proven Ways + Error Solving

Xiaomi TVs 32 inches (series Mi) TV 4A, 4S, 4C And others get firmware updates that improve performance, add new features and fix vulnerabilities on a regular basis, but many users face problems: the system does not find updates, freezes during the installation phase, or errors like E10001. In this article, we will analyze all the current methods of updating (via the Internet, USB-drive and hidden menu, and tell you how to avoid typical errors and what to do if the TV stopped turning on after a failed firmware.

It’s important to understand that the upgrade procedure for 32-inch Xiaomi models has nuances. For example, Android TVs (like Mi TV 4S 32) are updated differently than devices on PatchWall (like Mi TV 4A 32). We took these differences into account and prepared universal instructions that will suit most models. If you are not sure about your firmware version, you can check it in the Settings → About TV menu.

1.Preparation for the update: what to do before the start

Before you start updating, follow the mandatory preparatory steps to help avoid crashes and data loss:

• 🔌 Stable power: connect the TV to the network through the original power supply. If you use a network filter, make sure that it does not turn off the power when the voltage surges.
• 📶 Internet connection: for air updates (OTA) The speed should be at least 5 Mbps. Connect via Ethernet cable if Wi-Fi is unstable.
• 💾 Backup: Record the current image, sound and network settings (e.g., take a picture of the screen with the settings.
• ⏳ Time: The process can take anywhere from 10 to 40 minutes.Do not schedule an update before an important view.

Pay special attention to free space on the TV. You need at least 500 MB of free space to install the update. You can check it in the Settings → Storage menu. If there is not enough space, remove unnecessary apps or cache (under Settings → Apps).

⚠️ Note: If your Xiaomi 32 TV was purchased outside of official channels (e.g., on AliExpress), it may have modified firmware, and if you upgrade through standard methods, it will lead to a brick. If it contains a postfix mod or custom – use only firmware from your seller.
