Once you cut the adhesive on all sides of the phone you can slowly lift the display upwards and remove it.

The display cable is threaded through a hole in the midframe; guide it through carefully in order to free the display.

Before installing a new display, it's very important to remove all traces of the old adhesive from the frame, and clean the glued areas with isopropyl alcohol (>90%) and a lint-free cloth.

If the frame is bent, or if any glue or glass remnants are left behind, the new display will not mount correctly and may be damaged. If necessary, replace the frame.
