If you can get into recovery... Your not bricked. Sounds like you had a bad flash.
Sounds like you didn't do a Nandroid Backup!?!? If you did... Just restore that.
You can also wipe everything and reflashed the rom.
Or you can boot into Download Mode and Odin back to stock or just about any custom rom.
Also, you've got to give us a bit more info... You know things like what model GT you have, what rom were you flashing, what recovery your using...
The more info you give us the faster and better we can help you.
