Disconnect the LCD Video cable, shown to the right of the battery power housing. Gentle application of pliers is acceptable for this extra large connector.

Two additional connections must be undone before moving on. One can be found to the right of the front facing camera housing on the motherboard. It is small; treat it gently.

An identical connection can be found next to the antenna connection of the motherboard, diagonally across from the one you just disconnected.

Now all necessary wire connections have been undone and the motherboard can safely be removed.
