to remove the digitizer you will need to do the following
1- 2 screws at the bottom unscrew them
2- window sucker the screen and gently pull the screen will come off from the bottom.
3- carfully unclick 3 ribbons on the right marked 3,2,1 i think the last one will need a carful hand and it unclips.
this will make the whole front come off
now down the sides there are screws 3 each side unscrew and the screen will now pop off.
now the digitizer
to get this off i use a hairdrier to soffen the glue and take it steady and it will come off
clean glue off and replace with sticky pads in your new screen and replace in reverse
job done
