On the left side of the home button bracket you will notice a cushion that is on the top of part of the flex cable. We will be removing that

Apply a little heat (about 3-7 seconds worth of a hot air blower) to the front of the digitizer where this cushion is located.

Use the cutting side of the Halberd Spudger and gently seperate the cushion from the cable and bracket

Be careful as the flex cable in in-between the bracket and cushion. Don't lift the flex cable off the bracket just yet
