Place a suction cup near the bottom edge of the back cover, on the right side (opposite the speaker grille) of the USB-C charging port, above the microphone hole.
If your back cover is badly cracked, covering it with a layer of clear packing tape may allow the suction cup to adhere. If all else fails, you can superglue the suction cup to the back cover.
Pull on the suction cup with strong, steady force to create a gap.
Due to the adhesive's strength, this is very difficult and may take multiple attempts. If you can't create a gap, re-apply heat and try again.
Insert the point of an opening pick into the gap.
