the last thing i did was open this app called ROM manager, and tried to backup my ROM i believe. It took me to the "android system recovery" menu, and i didnt really know what i was doing, so i selected "reinstall packages", and then "reboot system now", and then it reset my phone and now all it does it show the samsung vibrant screen, then I get a small vibration, followed by a pause, then a triple vibration. I am able to go back to the system recovery menu, and nothing different happens when i go to "reboot system now" I even deleted all user data! im kind of a noob, so i would appreciate if someone would help me out here. Thanks.
