Disconnect: Touch screen flex cable LCD Display flex cable
  • Disconnect:

    • Touch screen flex cable

    • LCD Display flex cable

    • Charging Dock board flex cable - remove the foam and tape, then flip up the black lock before easing out the flex.

    • Coaxial antena cable - take your time here, be sure to pull the metal connector and not the cable or you risk pulling the cable from the connector.

  • Remove the 2x Torx T4 screws.

Take care when removing the coax connector. Mine was very tight and I managed to disconnect the coax cable from the connector. Phone is now in the bin :-(

Also, when removing the charging dock board flex cable, the connector has a black lock arm. Remove the foam pad and tape to reveal the lock. Gently ease the lock arm up then ease the flex out.
