Ok I need some help. I followed all the inotiuctrsns to he best of my ability and was able to get the phone successfully rooted. I went to install the new rom and from what the phone is telling me it installed successfully but when it goes to boot back up it doesn't get past the (SAMSUNG www,samsungmobile.com) screen. It's like there is no rom at all. I know I made one huge mistake and that was not backing up the original system. So there is nothing to fall back on. I can't get the new rom to work. HELP PLEASE???!!!???!!!???
