Is there a difference? I want to restore my iPad as new in the most thorough way as possible, but before I begin, I have a few questions. 1.) Is there a difference between DFU mode and Recovery Mode? 2.) Is there any danger in engaging in either mode? 3.) What should I use to thoroughly wipe my device? 4.) How do I begin the preferred mode? I keep hearing different ways to initiate "DFU" mode. Two common ones are plugging in the device while holding the home button, another is plugging in the device, holding down the lock and home button till screen goes black, then let go of lock but continue holding home... What should I do?? 5.) Do both modes (if they are different) prompt iTunes to have the "iTunes has detected a device in recovery mode" message, which will in turn allow one to proceed to easily exit this mode and begin the wipe? I just need huge amounts of clarification around all these things. Whenever I try and search I get different answers from every source it seems. ?.) Oh one more unrelated thing that I can't find a consistent answer for either - Does iTunes backup App Data? So the progress in a game for example will still be there when you backup and restore from it?
