  • Use the flat end of a spudger to pry the motherboard off the posts securing it to the metal display tray.

  • Do not try to completely remove the motherboard just yet. It is still attached by three ribbon cables.

  • Carefully peel the device information sticker off the left edge of the motherboard and EMI shield to reveal three connectors covered with tape.

  • It is not necessary to peel the entire device information sticker off the EMI shield.

  • Fold the device information sticker up against the top of the motherboard to keep it out of the way while you work.

  • Remove the pieces of tape covering the following ribbon cables:

    • Front-facing camera

    • Front panel ribbon cable

    • Display ribbon cable

I'm not sure why the dimensions I added to the display cable width were not approved for Step 14 (9/32" vs. 17/32"). Maybe I entered it in the wrong section? The reason I added it was because you cannot see the part number on the ribbon without removing the LCD, and I did not want to completely disassemble the phone at that time, rendering it completely inoperable before the part arrived.

I continually ran across "advise" from customers on Amazon (and elsewhere on the interwebs) stating "make sure you buy the LCD with the right width cable". This information, while well meaning, is utterly useless, since none of the advice I came across had the actual dimensions. It should be included somewhere in the teardown manual.

After some searching, I found the dimensions on the LCD product descriptions at www.repairsuniverse.com. I measured my own LCD ribbon, and can verify the 'wide' dimension is accurate:

  • Using the tip of an iPod opening tool, flip up the front-facing camera ribbon cable retaining flap.

  • Be very careful and gentle with these flaps. They are very easy to break or dislodge and equally difficult to reinstall.

  • Use a pair of tweezers to pull the front-facing camera ribbon cable straight out of its socket.

  • Carefully lift the motherboard out of the inner case, minding any cables that may get caught.

  • Be mindful of the top power button and side rocker switch, which may fall out of the front case when the board is removed.
