Hello, I have a problem with my iPhone 4s ... Yesterday I tried to downgrade iOS to an older version. However, the downgrade was not successful and now I stay with the iPhone, which just shows the image to connect to iTunes. However, iTunes reports an error when restoring the system: 3194 ... So I'm still with a malfunctioning iPhone and iTunes, which is not able to update / restore iOS, please help me in this situation .. Thank you, Matěj Švach
