use the buttons to put it in the new digitizer.

connect the flex cable to the board of the lcd screen. ( i forgot to take a picture of this , my apologies )

connect the flex cable again to the Phone ( where the plastic lid and screw was..)

put the digitizer again over the lcd screen. see that it is in the correct place.

these are the steps to follow. sometimes it is hard to see things on the pictures so again there is a good youtube movie from the guys from smartfastfix... see link in step 2 or 3 .
