Installing this firmware typically requires a USB flash drive and following a specific "boot-up" sequence: : Format a USB drive to FAT32 .
Press and hold the on the TV (not the remote) while plugging the TV back into the power outlet.
: Installing the wrong resolution firmware (e.g., 1920x1080 firmware on a 1366x768 panel) can cause a distorted display or a black screen. Ensure your TV's panel model matches the 1920x1080 specification before proceeding.
: Place all downloaded parts in the same folder and extract them to get the single firmware file (often named MstarUpgrade.bin or similar).
