: The TV will automatically enter standby mode (red LED) once finished. Do not unplug the TV or remove the USB drive until the process is complete.

: Unzip the archive and copy the firmware file (usually named allupgrade_msd338_4G_ref45.bin or similar) to the root directory of your USB drive. Preparation : Power off the TV and unplug it from the wall.

: After 3–5 seconds, the LED indicator should begin blinking red and green, signaling the update has started. You can then release the Power button.

: The firmware often comes in a multi-part RAR archive (e.g., part1.rar , part2.rar ). You must download all parts into the same folder before extracting the main .bin file.
