There are two common methods for ONIDA TVs depending on whether the TV is currently functional or stuck on a boot screen: Plug the USB drive into the USB 2.0 port of your TV. Go to Settings > Device Preferences > About . Select System Update and choose Update by USB .

Press and on the TV's local keyboard (not the remote).

: Ensure you have all parts (e.g., part01 to part05) in the same directory.

: Move the extracted firmware file (e.g., upgrade_loader.pkg or similar) directly to the root directory of the USB drive. Do not place it inside any folders. 3. Install the Update on Your TV

until the process finishes and the TV restarts automatically (usually takes 3–7 minutes).

To update your software using a multi-part RAR file like "part05.rar," you must first download all related parts (Part 1, Part 2, etc.) to the same folder on your computer. Firmware updates for large smart TVs are often split into multiple files to make downloading easier and more reliable. 1. Extract the Firmware Files

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

Keep holding the button for until the front LED begins to blink, indicating the update has started.
