Here we have the Samsung Galaxy S3 mini with the LCD broken. The touch works fine, but its easier to replace the entire assy.
First of all, remove the battery door, then the battery....
Then, unscrew all the screw from the bottom side. NOTE:All the screws has the same lenght

Step 2

Now, with a flat screwdriver or the plastic triangle, separate the rear case from the front case.
Here we have the call speaker. Its glued to the front, so we have to release it or desolder the 2 knobs on the flex cable.

Step 3

Remove the volume and power buttons.
Release the lower buttons and MicroSD connectors.

Step 4

Now, lift from the right side the board, and be careful, below is the LCD connector.
It´s turn to the HOT STATION. If you don´t have one of this, you can do it with a Hairdryer or a Heat gun
I don´t have any photo of the proccess, so I´m sorry for that. You must heat all the LCD area, and with special attention on the top and bottom areas.
Please be careful with the 2 lower buttons, they have this orange flat cable!!
As you can see, the LCD is totally destroyed, but it was broken before, so...

Step 5

Now, you can see that the touch screen were damaged too, so this is why I have purchased the whole unit assy.
PLEASE!! DON´T remove these adhesive tapes! They are neccessary for the new module (that doen´t have double sided tape )

Step 6

Now, place the new module on the chassis, and be careful with the flex cables.
To assembly all togheter, do the steps backwards, and don´t forget to place the volume and power up buttons!
Remember to put back the speaker
