Copy only the extracted .bin file directly onto the main directory (root) of your USB drive. Do not put it inside any folders. Flash the TV:
Use a program like WinRAR or 7-Zip to extract the .rar folder. You need to locate the raw file inside (it usually has a .bin extension).
Do not touch any buttons until the light stops blinking and remains solid or the TV restarts on its own.
Format a low-capacity USB flash drive to the FAT32 file system.
