Had you typed "stk500 -h" you would have seen the correct options.
First of all, -F means verify fusebytes, so you did not specify any fuse
byte at all.
-f sets the first fuse bytes 0 and 1 while -E set the extended fuse byte 2
-F verifies fuse bytes 0 and 1 while -G verfies the extended fuse byte 2

The "Fuse byte 0", "1", "2" output lines suggest there are three fuse
bytes.

The "-F3FD0" option looks like you are specifying two fuse bytes.

Was the program expecting you to provide a third fuse byte?
