    • Insert a SIM eject tool, bit, or straightened paperclip into the SIM card tray hole on the left edge of the phone.

    • Push the SIM eject tool into the hole to eject the SIM card tray.

    • Remove the SIM card tray.

  2. 262BmGVtxuLcbaCS

    • Heat an iOpener and apply it to the back cover's right edge for two minutes.

    • A hair dryer, heat gun, or hot plate may also be used, but be careful not to overheat the phone—the display and internal battery are both susceptible to heat damage.

    • Flip your phone over so the display is facing up.

    • Apply a suction handle to the middle of the display's left edge, as close to the edge as possible.

    • Place the tip of an opening pick in the small gap between the back cover and the display.

    • Pull up on the suction cup with a strong, steady force and push the opening pick down at a 45 degree angle until it slides into the gap between the back cover and the display.

    • If you're having a hard time inserting the pick, reheat the adhesive with an iOpener and try again.

    • Both adhesive and clips secure the back cover.

    • During steps that involve sliding the opening pick, keep it angled down at a 45 degree angle.

    • Slide the pick along the left edge down to the bottom left corner, and then up to the top left corner, to release the clips and slice the adhesive.

    • Leave the pick inserted in the top left corner to prevent the adhesive from resealing.

    • This is a good point to test your phone's functionality before sealing it up. Use this guide to run a hardware test. Be sure to power your phone back down completely before you continue working.

    • Apply new adhesive to the perimeter of the underside of the back cover after cleaning the relevant areas with isopropyl alcohol (>90%) and a micro-fiber cloth.

    • Insert the flat end of a spudger under the fingerprint sensor.

    • Gently pry up and detach the fingerprint sensor from the motherboard cover.

    • The motherboard cover is secured with tight clips.

    • Insert the flat end of a spudger in the gap between the frame and the bottom left corner of the motherboard cover.

    • Lift straight up with the spudger to release the clips securing the motherboard.

    • Don't pry against the battery, as this could damage it.

    • This may take take a few attempts. It you're having trouble, try gripping the spudger closer to the flat end.

    • During reassembly, press down around the perimeter of the motherboard cover to engage the clips.

    • Use the flat end of a spudger to pry up and disconnect the battery cable's press connector.

    • To re-attach press connectors like this one, carefully align and press down on one side until it clicks into place, then repeat on the other side. Don't press down on the middle. If the connector is misaligned, the pins can bend and cause permanent damage.
