Note: Ensure you have the latest iTunes on your computer. Open iTunes and connect iPhone to computer with a USB cable. You may get an error message saying iTunes could not connect to your iPhone because it is locked with a passcode. To make iTunes recognize your iOS device, you need to put your device into Recovery Mode. Here I recommend you to use, a free iPhone recovery mode tool that can put any iOS device (iPhone, iPad, iPod touch) into and out of recovery mode by one click. Open Tenorshare Reiboot, and click 'Enter Recovery Mode', wait for 10 seconds around, you'll find your iPhone has been in recovery mode, displaying a USB cable, the iTunes icon and a message saying 'Connect to iTunes'. ITunes should alert you that it has detected iPhone in recovery mode.
