Default Help. Stuck on boot.

I have an att sm-900a. I was messing with efs and such. Ended up with a soft brick. I have used the method to restore mj4 posted in the forums, but, it did not work for me. I think if I had a proper odin stock restore file the system will restore. Hope someome can help me restore my phone
