Introduction: Why Update Your Firmware on Mi TV Stick
Xiaomi Mi console TV Stick is a compact device for converting a regular TV to a smart TV, but its software becomes obsolete over time. New firmware versions bring not only bug fixes, but also support for modern codecs, improved optimization for streaming services, and even new interface features. AV1-YouTube codec and improved voice management via Google Assistant.
But not everyone knows that you can install firmware not only through automatic updates, but sometimes you need manual firmware: if the device is stuck on the logo, does not see new versions of the software via Wi-Fi, or you need to roll back to the previous version due to bugs. In this article, we will analyze all the current ways, from official updates through the menu to firmware through ADB and unlock the bootloader.
Before you start, consider that doing the wrong thing can turn a console into a brick, especially alternative firmware and modified recoveries, and if you're a beginner, start with the official methods, which are as safe as possible and don't require technical skills.
Official update via Wi-Fi (the easiest way)
This is a basic method that works for 90 percent of users, and it finds and installs updates, but sometimes it gets stuck or new versions don't show up.
- Connect the Mi TV Stick to the TV and go to the main menu.
- Open Settings → About the console → Update the system.
- Click Check for updates.
- If the version is available, confirm the installation and wait for the restart.
If the update is not available, check:
- 🔌 Internet connection stability (it is better to use a wired Ethernet adapter via USB-hub).
- 📅 Date and time on the console (incorrect settings can block access to Xiaomi servers).
- 🔄 Device region (some updates are coming first for China, then for the global version).
💡
If the console doesn’t see an update, try changing the DNS to 8.8.8.8 in the network settings.
The download speed depends on Xiaomi servers. If the process is stuck at 0%, reboot the console and try again. In rare cases, a factory reset helps (Settings → About console → Reset), but this will remove all installed applications.
Manual firmware via USB: step-by-step instructions
If the automatic update doesn’t work or you need to roll back to the previous version, use local firmware via USB.
