Firmware updates for Smart TVs are used to enhance current features, fix bugs, and in some cases add additional applications to the device. You can perform the update via the Web (recommended). However, there are times where we may need to update via USB in order to resolve a problem.

What you'll need:

  • If you are updating via the web, your TV should be connected to the internet
  • If you are updating via USB drive, you'll need a computer with an internet connection and a USB drive with enough free storage space.
  1. Open a web browser on your computer.
