I want to sell my iPhone, so i gave a reset all and theres a message that tells, that it will take like an hour, so it begun to fill the bar under the white apple that appears in the black screen, once the bar was full it turns off and restart, but never pass to other screen, it hold's in the white apple with the waiting sign turnig around, then the sign of waiting stops and turns off and restart again. How can i gave a restore if the iTunes never could recognize the device. Or how can I fix it!
