Hello doing some self repairs or at least checking what could be wrong with my logic board since Wi-Fi and Bluetooth have been greyed out. During the process of trying to remove my logic board I accidentally removed what I probably shouldn’t have thinking it was just waterproof tape after watching a video concerning it. Looks like there is a bit of copper underneath it maybe for insulation I’m assuming. Will I just need to replace the whole mother board?
You haven’t damaged the logic board that is just a sticker . But I’m afraid the logic board has been damaged as a greyed out Wi-Fi usually indicates that the solder pads between the layered boards have been compromised or the Wi-Fi IC has become faulty. Unless you have the equipment and microsoldering skills it will need to be sent to a reputable repairer. EDIT If the sticker will not stick back on you can use thin strips of double sided tape. The grey paste is heat sink. The Wi-Fi IC is shown and is on the bottom layer of the board.
