If you are not good at repairing small electronics (taking apart and putting back together) then get a pro to do it. I found out the hard way that trying to pry off the cover around the display (with the tools that came with my replacement LCD for my samsung a737 ) is the wrong way.
Under the battery are two very small screws that come out. Remove these first, they should be very short and have a very wide and flat head.
Then with the phone
closed pry up the bottom the of the top slider and then push the slider top down (some what hard to pry and slide). You only need to move it about 1mm then you should be able to lift the whole top off. This is the hardest part of the job.
Then disconnect the the ribbon cable by flipping up the little gard along the top of the ribbon at the connector. This guard rotates to a 90degree angle straight up. Be carefull to not rip appart the flip connector. then slide the ribbon out.
Then flip the top over and remove the now exposed screws on the top along the edges.
and now you should be able to figure everything else. Three more ribbon connectors to the display to finally remove.
To put back together again just do the same in reverse.
I charge $30 plus shipping to do this for you. Plus the cost of the screen if you don't have a new one to ship and use.
Looking towards the future with you,
