I followed all the instructions, but when I try to use Odin MultiDownloader, it gets stuck at the first box and the progress bar is halfway. What am I doing wrong? The phone turns on now, but I don't get wifi or service. Please help. (By the way, I am using a MacBook with Windows 7 on it. Could that be the problem?) Maybe there is a way you can put a custom room on with out odin. If there is one, can someone tell me where.
