                  - 
            Use the opening tool to lift the panel from the back cover 
- 
            The panel is clipped to the frame so you should feel the clips release 
- 
            Sliding the opening tool sideways after opening the first clips helps opening others 
- 
            You will need to open clips on all 4 sides 
 
- 
            
- 
                  
                  - 
            Lift the panel out of the back and put it on a soft surface with the glass down without stretching the flex cable connecting the back and the mainboard 
- 
            The element forming the three buttons will probably fall out at this point. Put it aside but remember to put it back into the back cover before closing the device

                  - 
            The wifi antenna is glued to the frame 
- 
            Carefully peel it of without tearing it apart 
- 
            It is sticky enough to hold again later without extra glue 
 
- 
            
- 
                  
                  - 
            Unscrew the speaker (mounted at the top with metal surfaces) 
- 
            Lift the front camera out of its hole. It has no screws or clips 
- 
            Move those parts inwards so they rest on the back of the LCD 
 
- 
            
- 
                  
                  - 
            Unscrew and lift aside the black plastic that holds the back camera in place 
- 
            The camera itself can remain 
- 
            Remove the washer screw holding the headphone jack in place (next to the camera) 
 
- 
            
- 
                  
                  - 
            Carefully lift the round sensor from its position in the frame 
- 
            Remove the speaker cables from their trenches in the black support element, it may be covered by tape 
- 
            Unscrew the element and put it aside 
 
- 
            
- 
                  
                  - 
            Remove the flat cable connecting the touch from the mainboard by flipping up the black latch holding it in place 
 
- 
            
- 
                  
                  - 
            Remove the screws holding the mainboard 
- 
            Lift it up carefully to access the LCD clips underneath 
 
- 
            
- 
                  
                  - 
            Unclip the LCD panel from the front glass panel by carefully wedging an opening pick between the panel and the clips holding it in place 
 
- 
            
- 
                  
                  - 
            You can now swap the front glass and touch unit 
- 
            The replacement unit has a protective foil on the inside. You need to remove that before installing the new glass 
- 
            The foil started to leave residue on the glass so i used a hair dryer to weaken the glue 
 
- 
            
To reassemble your device, follow these instructions in reverse order.
Congratulations you now have a touch device again
