Can't get past activation lock on old ipad mini
I have an old ipad mini that I have been trying and trying to reset so I can use it for something. The problem is, there is an activation lock on it. But I cannot remember my old apple ID or figure out what the ID used on it was. I do not remember it at all. I remember I did change my apple ID a long time ago but I cannot figure out what it was before then and this ipad mini isn't on my current account. I don't know if I had one apple ID but then used another or what. But I know my current one is for a gmail account. The one on the mini says the first letter and the rest of the first part blacked out and then @icloud.com. I don't know what to do and I'm at a complete loss on what to do. I mean, I got it by winning it in a raffle, decided to let my parents barrow it and then they kept entering the wrong password and so locked themselves out of it. It's hardly been used ever since. I need help. Desperately.
