I finally got it done.the sm t320 is allmost the same like the sm t325.thé hardest part was to get the screen out of the frame.my new lcd came without the motherboard housing so I had to use a heatgun to get the old screen off.it is glued with some very sticky double sided tape,but with a little patience I got it off without dameging the tape and I could reuse it.anyways your tutorial was very helpfull to get the job done.
