: Press the Home button on your remote and navigate to the Settings (gear icon) in the top right.

: While holding the Power button on the TV (not the remote), plug the power cord back in. Continue holding the button until the "Software Upgrading" or "Installing System Update" screen appears.

If your TV is operational, use these steps to download and install the latest version directly:

: Open the .rar archive on your PC and extract the firmware file (usually named MstarUpgrade.bin or similar) to the root directory of a FAT32-formatted USB drive.

: Select Check for Update . If a new version is found, select Download . Once it reaches 100%, select Restart Now to apply the update. Method 2: Manual USB Update (For .rar/.bin Files)

: Insert the USB drive into the TV's USB port.
