Make sure you haven't bent the contact prongs on the daughter board and antenna contact points on the rear case.
Also the daughter board and the antenna is carrier-specific, make sure you have bought the one for the correct model. The model is written on the ribbon cable connecting to the main board, like SM_G920A for AT&T.

So are the red or blue wires for mobile data? I thought they were Bluetooth and wifi.
