Because if you can install freegee, it means you were able to boot your phone past both logos.
So can you turn on your phone and if not it may be bricked.
If you did unlock the bootloader, all you have to do is when your phone powers up, hold the power + voume button and it'll display the fastboot menu. From there press the volume button down twice and then press the power button. Then you can boot into the recovery and install any rom you like.
If your trying to install a kitkat rom, you need to install a kitkat compatible recovery.
