Einleitung

This is a prerequisite-only guide! This guide is part of another procedure and isn't meant to be used alone.

  1. xLsBXZmv3ogqEF6j

    • Completely power off your phone before you begin.

    • Heat an iOpener and apply it to the back cover's left 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 back cover and internal battery are both susceptible to heat damage.

    • Apply a suction cup to the back of the phone, as close to the bottom left corner as possible.

    • Pull up on the suction cup with a strong, steady force to create a gap between the back cover and the midframe on the left edge.

    • Depending on the age of your phone, this may be difficult. If you're having trouble, apply more heat to the edge and try again.

    • Insert an opening pick into the gap.

    • Lift the back cover from the phone and remove it.

    • If the back cover is still stuck to the midframe, slide an opening pick around the edges of the phone until the cover separates completely.

    • During reassembly:

    • 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.

    • Follow this guide to replace the back cover adhesive.

  16. WCMDBHiAholvTAig

    • Insert a spudger between the motherboard cover and midframe on the top right edge of the phone.

    • Pry up with the spudger to release the clips securing the motherboard cover.

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

    • Gently pull the motherboard cover up and away from the phone and remove it.

    • Don't pull quickly or forcefully, as the heat spreader very loosely secures the motherboard cover to the battery.

    • Use the pointed end of a spudger to pry up and disconnect the battery'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, causing permanent damage.

    • Take care not to puncture the battery with your tweezers—a punctured battery may leak dangerous chemicals or cause a fire.

    • Use tweezers to grip the top and bottom of the blue antenna's coaxial connector, as close to the connector head as possible.

    • Lift straight up to disconnect the cable.

    • Be gentle when disconnecting the cable, as it's very easy to tear the socket from the motherboard.

    • During reassembly, make sure to put the cable back in its clip on the motherboard.

    • To re-attach coaxial connectors like this one hold the connectors in place and gently press them straight down with your finger or the pointed end of a spudger.

    • Remove the motherboard from the phone.

    • During reassembly, make sure that all of the cables that connect to the motherboard (interconnect, battery, antennas, display, and button assembly) are out of they way so they don't get stuck under the motherboard when it's reinserted.

  30. oqFQVFhmsitFeiML
