The file you require is the 4th one down. F2404_3_18_1a4_flash_image_NONE.rar

Extract this to a folder using 7Zip or WinRar and it will give you the .W file you require.

The 6th down is a later version of the file linked in the PDF. F2404_3_33_8a4_fs_kernel_NONE.zip

This is a zip file and should be extracted before use.
