Most if not all those ROMs come from forums that deal with going back. I can't guess where you got this so I can't write other than this.
Or take it to your carrier support counter and have them reflash the phone.
I decided to root my Samsung Galaxy S3, it worked fine until i decided to load a ROM. After loading it, it said it may lose my root and asked if I wanted to fix it, I hit yes and my phone went black and now wont turn on nad cant go into recobery mode either. If you know how to fix this please help.
