Replace screen ipad air
I have two Ipad air 128GB both have Model A1474 but when I replaced screens they are different inside one had 3 wires and the other one it only has two wires on the screen that I was sent had no home button but does work but the problem is when I took the home button off the old one it fell apart and I don't know where to find the ribbon wire to replace or how to reassemble the old one why did I get two ipads but different inside? now I wonder if it will be touch screen when I put it back together
