Introduzione

The OnePlus 5 has a small daughterboard that mainly houses contact points that connect to loudspeaker and charging assemblies. If you are experiencing issues with any of the functions housed in the bottom half of your phone (e.g., microphone, loudspeaker, charging port) follow this guide to replace the daughterboard in your OnePlus 5. The hardest part of this guide is getting the frame clips of the back cover free to access the internals.

Some guide images will show the battery already removed from the phone. You do not need to remove the battery for the daughterboard procedure.

    • Insert a SIM card eject tool, bit, or a straightened paperclip into the small hole below the SIM card tray, located near the rear cameras on the edge of the phone.

    • Press firmly to eject the tray.

    • During reassembly, be sure to properly orient the SIM tray you you insert it.

    • There is a high risk of damaging the display panel if this opening procedure is improperly followed.

    • The following four steps show how to pry the rear case from the plastic frame. Read through the steps first before attempting the procedure.

    • There are two different seams between the body and the screen of the phone:

    • Display panel seam: This seam is part of the display assembly. Do not pry at this seam, or you will separate and damage the display panel.

    • Frame seam: This is where the plastic frame meets the back cover. Only pry at this seam.

    • There are twelve clips that hold the frame against the rear case. Be aware of their location as you pry the back cover off in the following steps.

    • As you work, try not to accidentally power on the phone. If you do, turn the phone off before resuming disassembly.

    • Place a suction cup near the bottom edge of the display.

    • Pull on the suction cup with strong steady force.

    • Press the edge of an opening tool straight into the frame seam near the suction cup until the edge wedges between the plastic frame and the back cover's lip.

    • Due to tight tolerances, this will take substantial force. Using a new opening tool with an unmarred edge will help with this step.

    • Once the opening tool's edge is wedged in position, carefully slide the tool along the bottom edge of the phone.

    • Carefully guide the opening tool around the left corner of the phone while keeping the tool's edge within the seam.

    • Continue sliding the opening tool along the long edge, releasing the clips along the way.

    • The last clip in the top-left corner near the front-facing camera is recessed and can be difficult to release. Take your time and use the flat end of a spudger or an opening pick to help.

    • With the bottom and left edge of the phone freed, gently wiggle the frame to release the top and right edge clips.

    • The frame is still connected to the back cover by a long flex cable. Do not remove the back cover.

    • During reassembly, pause here to test your phone's functionality before securing the back cover.

    • To reinstall the back cover:

    • Align the top edge of the frame to the back cover and ensure that the top clips slip into place.

    • Squeeze along the long edges of the phone to snap the remaining clips into place.
