1st. NEVER, when you have little experience in such things, NEVER USE BRUTEFORCE before you can say that you have enough experience on flashing.
2nd. You could use, Breakin, it's a lot safer for beginners.
3rd. Try to reflash the phone with your original firmware, IT SHOULD WORK.
4th. If NOTHING, but NOTHING, you have tried by flashing or so, try WOTAN, it revives you phone, there are some guides how U shall do it.
5th. BACKUP EVERYTHING you think is needed to revive your phone, in case that something goes wrong.

Hope this FIVE things help you in the future.
