  7. 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

  8. Locate the L-shaped I/O Board.
    • Locate the L-shaped I/O Board.

    • Locate the gray 3G Antenna wire.
