Locate the two connectors at each end of the FPC.
Use the flat edge of a spudger tool or your fingernail to gently pry each connector straight upwards out of its socket, then remove the FPC cable from the unit.
While a metal spudger tool is shown here, it is best to use a plastic spudger / opening tool when possible, and only use a metal spudger as a last resort!
You should now see the yellow-colored strip on the metal base marking the location of the FPC

Шаг 8

Locate the L-shaped I/O Board.
Locate the gray 3G Antenna wire.
If the gray 3G Antenna wire is connected to your I/O Board, disconnect it. If for some reason the 3G Antenna wire is already disconnected from the I/O Board (as it was in this device) simply lift it out of the way.

Locate the light sensor connector.
Use the tip of a spudger or your fingernail to lift up and flip the small retaining flap on the connector. The light sensor ribbon cable should now be free, so simply pull it out.
This is a ZIF (zero insertion force) connector, which requires no force to remove / plug in the connector.
Please make sure you lift up on the small retaining flap on the connector, not the connector itself!
Use a Phillips #00 screwdriver to unscrew the single 3.0mm Phillips screw next to the light sensor connector.

Locate the speakers module, which consists of 2 square black speakers connected by wires.
Locate the white and blue Home Key FFC ribbon cable between the speakers.
Use the tip of a spudger or opening tool to lift up and flip the small hinge on the connector. Then gently pull the FFC ribbon cable out its connector socket.
While a metal spudger tool is shown here and may be used, it is best to use a plastic spudger or opening tool when possible. It is easier to damage cables when using metal tools, so be extra cautious when using a metal spudger like the one shown here!

Шаг 13

Locate the speaker cable. Use your fingers to pinch each side of the black head of the speaker cable, and gently pull it out of its socket.
The metal spudger shown in the photo is used only to identify the speaker cable, not remove it.
If you're unable to get a good grip on the black connector head itself, gently pull from the wires near the connector head's base.
Be sure to pull on the wires near the base and evenly on the full width of the wires so no individual wire is over-strained, which may cause damage!

Шаг 14

Unscrew the 4mm Phillips screws securing the speakers module to the device using a Phillips #00 screwdriver.
There are two 4mm screws in total (one screw securing each speaker).

Редактировать

Шаг 15

Now both speakers should be free. Use the edge of a spudger tool to lift each speaker off the device, or use your hands to simultaneously lift each square black speaker off of the device.
If intact, the two speakers should be connected by wires, forming a one-piece speakers module.

This is a ZIF (zero insertion force) connector, which requires no force to remove or plug in the connector.
Please make sure you lift up on the black retaining flap on the connector, not the connector itself!
