Carefully lift the logic board from the end closest to the speaker enclosure and slide it away from the top edge of the iPhone.
Remove the logic board.
Before reassembly, be sure to clean all metal-to-metal contact points on the logic board (not the mating halves of connectors) with a de-greaser such as windex or isopropyl alcohol. The oils on your fingers have the potential to cause grounding issues.
There is a small rubber bumper that sits on the top edge of the logic board where the digitizer and screen cables come through the case. It protects the cables as they bend over the top of the logic board. This can either get stuck to the cables or fall off the logic board when it comes out. Look back over step 22 for more details.

别忘了在22步所提到的小橡胶保险杠，它可以在电缆弯曲过度时保护线缆。 它有可能在你拆卸的过程中滑落下来，掉在逻辑板上。请回顾先前操作来让它处于正确位置。
