Bought a full replacement assembly, lcd+digitizer+glass+bezel, and am trying to connect the 1 ribbon and 2 snap-connector lines. Having lots of trouble figuring out how to gently and safely connect the Ribbon (the one that goes under the connector that you have to lift up to a 45degree angle and shut). Any advice on a tool, or how far to get it in before it works? I'm getting frustrate after a few hours of trying. Thanks!
