There are many reasons you want to factory reset your iPhone: you forgot the iPhone passcode, the iPhone is disabled, and you got a second-hand iPhone and the iPhone screen passcode does not work, and so on. If you do not have the iPhone passcode, is it possible to factory reset the iPhone without the passcode or iTunes? You can learn effective ways in this post.
