We have Iphones at work. In this case it is a Iphone 6s. One of my techs dropped it and it needed a battery. He was set for an upgrade. So he got him an iphone 8 for free. I was able to keep the old iphone. I fixed the battery and screen. But I can't get the "Remote management software" off. I have tried many resets but nothing works. Two questions. Is it possible to remove? And if so what should I use? Thanks for listening. I did ask and the company does not want it back.
