I've got an iPad Mini that I bought late 2015, and have not used it - in fact I forgot I had it. I never set it up properly and haven't used it for anything at all, really.
I got it out today and plugged it in, charged it up and it asked me for the 4-digit passcode. I hadn't a clue. I tried ex's dob (wasn't an ex when I got the iPad) and another relevant date but these didn't work and it locked me out.
Now have no idea what to do. I have no other iPhone or Apple products, no AppleID or anything.
In the words of Sweet, I just haven't got a clue what to do.
