Update Xiaomi Mi TV 4X to the latest version: all ways and solutions to problems

Xiaomi Mi TV 4X is one of the most popular smart TVs of the brand, but over time its firmware becomes outdated, bugs appear or new features become unavailable. Software update solves these problems, but many users face difficulties from the lack of notifications about new versions to errors in installation. In this article, we will analyze all the current ways of updating (including hidden), tell how to avoid errors, and give tips on how to restore the TV if something goes wrong.
