Here is a step-by-step guide based on real user success stories:

While holding the power button, plug the TV power cord back into the wall outlet.

The TV will automatically restart once the installation concludes. Do not press any buttons during this reboot phase. Method 2: Manual Update via USB Drive

Ensure the firmware file is in the root directory of the USB drive and not hidden inside a subfolder. Double-check that your USB drive is formatted to FAT32, as NTFS or exFAT formats will fail to register.

Navigate to the or Setup icon (often represented by a gear symbol). Scroll down and select System or About TV . Click on System Update or Software Update . Choose Network Update or Check for Updates Online .

: If your TV runs smoothly after a manual update, disable automatic network updates. This prevents unexpected background downloads from destabilizing your system.
