Insert an opening pick into the right edge of the phone and slide it upwards towards the top right clip.

You do not need to insert the pick more than 2 mm into the edge. If you insert the pick all the way in, you may risk damaging flex cables.

Slowly slide the pick past the clip to disengage it from the frame.

At this point, the right edge of the midframe should be free from the case. If it isn't, slide an opening clip up and down along the right edge.
