Hey guys. Before I begin, I want to let you know that I've already checked out all the other thread for unlocking Samsung Captivate. I did what was told in those threads but I was unable to successfully unlock my Captivate. I even looked at numerous tutorial videos on youtube, but they didn't pull through either. I downloaded the "Generate Unlock Windows.zip" from xda-developers, and used winrar to extract it. After extracting it, I opened the "Generate_Code" and the big black box popped up. From there, I'm suppose to get the unlocking code but it says "error: device not found" and "Error: unable to find file <.Wnv_data.bin>" Please help me unlock my Samsung Captivate to use on T-Mobile! Thanks in advance!!
