When reinserting the SIM card, ensure that it is in the proper orientation relative to the tray.

Before disassembling your iPhone, discharge the battery below 25%. A charged lithium-ion battery can catch fire and/or explode if accidentally punctured.

Power off your iPhone before beginning disassembly.
Remove the two 3.4 mm P2 Pentalobe screws on the bottom edge of the iPhone, next to the Lightning connector.

Optionally, apply mild heat to the lower edge of the iPhone using an iOpener or hair dryer for about a minute.

Heat softens the adhesive securing the display, making it easier to open.

Opening the display on the 6s separates a thin strip of adhesive around the perimeter of the display. If you prefer to replace the adhesive, have a set of new adhesive strips ready before you continue. It's possible to complete the repair without replacing the adhesive, and you probably won't notice any difference in functionality.

Apply a suction cup to the lower left corner of the display assembly.
Take care not to place the suction cup over the home button.
If your display is badly cracked, covering it with a layer of clear packing tape may allow the suction cup to adhere. Alternatively, very strong tape may be used instead of the suction cup. If all else fails, you can superglue the suction cup to the broken screen.

Pull up on the suction cup with firm, constant pressure to create a slight gap between the front panel and rear case. Take your time and apply firm, constant force. The display assembly is a much tighter fit than most devices and is held down with adhesive.

Pulling too hard may damage the display assembly. Apply just enough pressure to create a small gap between the display assembly and the rear case.
If you have any trouble, heat the front of the iPhone using an iOpener, hair dryer, or heat gun until it's slightly too hot to touch. This will help soften the adhesive securing the edges of the display.

There is a notch on the underside of the display, just above the headphone jack. This is the safest place to begin prying the phone open. Place the flat edge of a spudger into the gap between the screen and rear case, directly above the headphone jack.

Use the suction cup to open the display, breaking the last of the adhesive. Don't open the display more than 90º, as it is still connected at the top by three cables that may break if stretched.

Gently grasp the display assembly and lift it up to open the phone, using the clips at the top of the front panel as a hinge. Open the display to about a 90º angle, and lean it against something to keep it propped up while you're working on the phone. Add a rubber band to keep the display securely in place while you work. This prevents undue strain on the display cables.

Remove two Phillips screws securing the battery connector bracket, of the following lengths:
One 2.9 mm screw
One 2.2 mm screw
Throughout this repair, keep track of each screw and make sure it goes back exactly where it came from to avoid damaging your iPhone.

Use the point of a spudger to lift and disconnect the antenna cable from the bottom end of the logic board. To reconnect antenna cables like these to the socket, carefully align the connector to the socket, then use the flat end of a spudger to press down. It should click in place. If not, check for alignment. Do not use excessive force.

Carefully lift the antenna cable and de-route it from the edge of the phone. Use the point of a spudger to help lift the cable to free it from the retaining clips. If the cable does not have enough room to lift up, loosen this Phillips screw securing the logic board so that the board can give more wiggle room. Be sure to re-tighten this screw during re-installation.
