I friends I have bought a brand new iPhone a month ago but I am having a problem with it. I tried many times to restore my iphone with Apple legitimate software. Do not try to escape from jail. Whenever I get an error. 14 or 21 when he was going to test the software. I tried rebooting the system, changing USB ports and even a Windows system. Nothing is working. Any ideas? Right now I am caught in restore mode.
