Apply a heated iOpener to the bottom edge of the back glass for two minutes.

Apply a suction handle to the bottom edge of the back glass, above the USB-C port.

Pull up on the handle with a strong, steady force to create a gap between the back glass and the frame.

Insert the tip of an opening pick into the gap.

There's a delicate cable connecting the back glass to the phone, right next to the volume up button. Don't insert your pick here to avoid slicing the cable.

There are multiple spring contacts around the perimeter of the phone. Be extra careful not to insert your pick deeper than suggested in each step to avoid bending these contacts.

Slide your pick back and forth along the bottom edge to separate the adhesive.

Leave your pick inserted in the bottom right corner to prevent the adhesive from resealing.

Heat the right edge of the back glass until it's hot to the touch.

Slide your pick around the bottom right corner and halfway up the right edge, or until you feel a hard stop at a clip securing the back glass.

Leave this pick inserted to prevent the adhesive from resealing.

Heat the top edge of the back glass, including the area around the volume buttons, until it's hot to the touch.

Slide your opening pick across the top edge and around the top right corner to the volume up button to separate the adhesive.

Gently swing open the back glass towards the volume buttons.

Support the back glass with a clean, sturdy object like a small box to avoid straining the cable.

Remove the logic board.

Hold the logic board above the phone so the socket on the underside of the board is close to the front sensor cable.

Use your finger or a spudger to press the front sensor cable connector into its socket on the logic board until it clicks into place. Don't try to force the connector into place. If you're having trouble, reposition it and try again.

Use your fingers or a spudger to gently hold all the loose press connectors out of the way so you can lay the logic board in place.

Lay the logic board in its recess.

Wrap a lint-free cloth or a coffee filter over the point of a spudger and apply a few drops of highly-concentrated isopropyl alcohol (over 90%) to it.

Wipe in one direction along the perimeter of the frame to clean the adhesive residue.

Lay the adhesive sheet over the frame to determine its proper orientation.

Grab the tab in the corner of the adhesive sheet and peel the liner to expose a third of the adhesive.

Carefully align the exposed edge of the adhesive strip with the corresponding edge of the iPhone's frame.

When it's correctly aligned, gently press the exposed adhesive strip onto the frame.
