Pls help me to solve it
The likely problem is your iTunes is not current, possibly because your operating system is not current.
The current version of iTunes is 12.4.3. You need this version, or one very close to it, to support your iPhone.
iTunes 12.4.3 requires at least Windows 7 or OS X 10.8.5.
