Pre-Update Checklist: Preparing Your L43M4-4AIN

A failed firmware update can brick your TV. Follow this checklist strictly:

Stable Power Supply: Do not perform an update during a storm or in an area with frequent power cuts. A power failure during writing firmware corrupts the motherboard.
Sufficient Storage: Ensure your TV has at least 500MB of free internal space. Delete unused apps if necessary.
Backup Settings: While rare, updates can reset your picture and sound settings. Write down your custom calibration values (Contrast, Brightness, Backlight).
Internet Connection: For OTA updates, use a wired Ethernet connection for stability. Wi-Fi works but is slower.
Patience: The TV may restart 2-3 times. Do not press the power button or unplug the TV during the process.
