Remove the USB drive and turn on the television. Note that the very first boot after a firmware flash can take anywhere from 3 to 5 minutes as Android configures the system cache. Important Precautions and Troubleshooting

. By making these system files available in the "right circles," thousands of televisions are saved from landfills every year. It represents a shift from "replace it" to "reflash it," proving that even in a world of high-tech hardware, the most powerful tool for longevity is often a small piece of code.
