The Ultimate Guide to Coby TV Firmware Updates Updating your Coby TV firmware can resolve software glitches, fix HDMI connectivity issues, patch audio bugs, and sometimes even restore a TV that refuses to boot past the logo screen.

Copy the firmware file you have downloaded onto the root directory of your USB drive. The "root directory" means the top-most folder of the drive—not inside any subfolders. Some firmware files may come as compressed archives (e.g., .zip or .rar files). If so, extract the contents before copying them to your USB drive. The firmware file may have a specific name like "update.bin" or "upgrade.bin" or something similar. Do not rename the file unless instructed to do so by documentation that came with the firmware.
