My mom and twin brother are really confused about a major problem that he's having with an iPad 4 cellular running ios 9.3.1.
Every time he turns it off and back on, it keeps saying that it needs to be activated. My mom's tried restoring it to no avail. She's also tried downgrading (which I don't know how to even do), but it's saying something about not able to register or something like that.
I really hope that you can help my mom and twin brother out.
And just to clarify, it's when he completely turns it off, not just when he locks the screen.
