Take note of the screen adhesive layout before continuing. Also, note the pictures of the display and main board to better see what to avoid:

These areas only contain adhesive and are safe to cut.

The display board and flex cables sit here close to the edge. Cut carefully and don't insert the pick more than 1/8 inch (3 mm).

Fragile antenna cables lie under this part of the screen. Carefully follow the procedure in step 13 to avoid damaging them. The adhesive is also the thickest here.
