When the hinge breaks loose from the back cover it is because the three screws that hold the hinge t5o the back cover have nothing to screw into. The female part breaks off of the back cover. I have one right now that I am trying to find a work around for since the new back cover is not available anywhere on the planet earth right now. I am not sure if it is worth trying to glue the plastic back into the the screw on the right is with the black plastic insert that has broken off the back cover and the screw on the left is what the screw looks like when it is screwed in to hold on the hinge if the backcover is not broken in this way. The picture is where the hinge screws and inserts have broken out, see the three holes? if it can be glues back into the hole it left it might work. Otherwise the LCD and Digitizer will continually separate. If I come up with something I will post it
