Hello, I have a problem with connecting iPhone 5s 32gb to iTunes. I made reset all content and settings and wanted to restore my backup via iTunes. My iPhone iOS is up to date - 8.1.2 and iTunes also running newest version - 22.214.171.124. Computer has windows 8.1 operating system, but the problem is not about the computer, because I also tried to connect it to macbook pro as well and it also did not do anything. It simply does not recognize any hardware on any computer when I connect it to usb. Cord is working with other iPhones (iPhone 6), so this is not the issue as well. I am running out of ideas, maybe someone could help me with it? Thanks.
