Unzip the entire zipped file directly to a freshly formatted thumbdrive rather than the hard-drive.
When it asks you which directory to use, use the root drive of your thumbdrive.
Your firmware update will be ready for the television after that, so continue to follow the instructions from there.
Does that help?
I want to update the firmware in my Samsung LN40B540P8F TV. I dowmloaded Saturn4_firmware.exe from Samsung. When run, it creates files in two sub-directories: T-STL3FAUSHC and T-STL5PAUSFC. Which sholuld I use, and which of the 5 files in the sub-directory should I put on the USB drive?
