Before diving into the "how," let’s explore the "why." Many users ignore firmware updates, but on a portable Android TV, they are essential for several reasons:
If your unit is running slow or apps crash, your only official sources are:
Xiaomi often adds features like improved HDMI-CEC control, better audio passthrough (e.g., Dolby Audio fixes), or an updated PatchWall interface.

If available, you will see a new firmware version (e.g., V1.5.124 or RTT.210527.001). Click Download and wait. The file size varies from 800MB to 1.5GB.
