Sorry the instruction wasnt clear. 1. you need to create a bootable usb drive (instruction is included in the extra folder) 2. copy all files in the modified bios and utility to the drive 3. boot up your system via the bootable usb drive 4. at command prompt, type F.BAT 5. Press Enter key the oem certificate must match the mod which is HP
I honestly dont know, as i noticed different sub-model uses different bios. so you better get yours right from samsung site.
