Step 1 - Rear Panel

  • Prior to disassembling your iPhone, make sure to turn it off.

  • Two 3.6 mm Pentalobe screws next to the dock connector need to be removed

  • While assembling the phone again, we suggest you to replace the 5-point screws with equivalent Phillips screws.

  • The 5-Point Screwdriver is meant to be used only once, as it may strip the screws.

Step 5

  • With a help of plastic opening tool, you need to pull the pressure contact which is positioned below the battery connector.

  • When the pressure contact is being reinstalled, it needs to be cleaned with a degreaser such as windex or isopropyl alcohol. The natural oils on your fingers may accidentally create wireless interference.

  • Carefully separate the battery connector from its socket on the logic board by using the edge of a plastic opening tool.

  • Make sure only to raise the battery connector and not the connector on the logic board. If you push the logic board connector, it may happen to completely break the connector.

Step 14

  • Carefully lift the speaker enclosure assembly out of the case using the plastic opening tool, paying attention not to damage the EMI fingers on the attached Wi-Fi antenna.

  • Remove the speaker enclosure assembly.

  • Prior to reinstallation of the speaker enclosure assembly's screws, check if the Wi-Fi grounding fingers are installed below the lip in the iPhone's metal case as shown in the third picture.

  • Prior to reassembly it is necessary to clean all metal-to-metal contact points between the grounding fingers of the Wi-Fi antenna and the case of the iPhone using a de-greaser such as windex or isopropyl alcohol. The natural oils on your fingers may accidentally create wireless interference issues.

Step 22

  • With the edge of the opening tool gently lever the screen around its perimeter.

  • Remove the screen from the iPhone.

  • When re-assembling the screen, make sure that the digitizer and screen data cable are pulled all the way through the slot cut into the outer case. If not, the digitizer cable will not extend to its socket on the logic board.

  • Do not forget to move the home button from your old screen to the new one since it not provided in most cases. Also check that the connector for the speaker hole is provided present in the replacement; if not, switch it over from the old screen.

  • After you finish the reassembly, we suggest you to apply a new screen protector in order to protect your screen from scratches.
