How to reflash Xiaomi TV: official and unofficial ways

Updating the firmware on Xiaomi TV is a procedure that can solve performance issues, add new features, or even “resuscitate” the device after a crash. However, incorrect actions lead to “bricking” (complete inoperability) of TV, especially if it is unofficial firmware or models for the Chinese market. TV 4A/4S/4X/5 In this article, we will discuss all the current methods of flashing, from official updates to manual restoration through the Internet. USB or ADB.

Many users face difficulties due to regional restrictions: Chinese versions of Xiaomi TV are often deprived of Google Play, have stripped down functionality or work only with Chinese services. Flashing to a global version of the software can solve these problems, but requires caution. Next, detailed instructions for different scenarios, from simple upgrades to deep recovery.

1. Preparation for flashing: what you need to know

Before any firmware manipulation, be sure to identify the model of your TV. This can be done in the Settings menu → About the TV or on the sticker at the back of the case. Chinese versions usually have CN suffixes (for example, Mi TV 4X 55" CN), and global ones are Global or IN (for India).

Also check the current version of the software. If the TV is stable but you want to upgrade "for the sake of new features," make sure that the new firmware does add something. For example, in the Mi TV 5 Pro, the upgrade from MIUI TV 2.0 to 3.0 brought support for Dolby Vision, but for older models (4A 2018), the changes may be minimal.

• 🔄 Restart the TV and router – sometimes cache resetting helps.
• ⏳ Wait 1-2 days: Xiaomi can roll out updates in stages.
