Samsung Galaxy S25 USB-C Board Replacement

Do not start this procedure with a fully charged Galaxy battery, as damage could cause it to ignite.

• Unplug all cables from the device.
• Power off the phone by holding the side key and volume down button, then selecting Power off.

Insert a SIM eject tool, bit, or a straightened paper clip into the SIM card tray hole until it ejects.

• Be aware that there is a small mic hole nearby, not to be confused with the SIM tray.
• Once ejected, carefully remove the SIM card tray.

Cracked glass can cause injury or complicate disassembly.

• Apply packing tape strips to the cracked glass, covering it completely.
• Maintain a single strip of non-overlapping tape at the bottom edge, sufficient for suction cup fitment.

Ensure no tape adheres to the frame. Consider wearing safety glasses during repair.

Use caution when heating the back cover as improper use can damage the display and/or battery.

• Apply an iOpener to the bottom edge of the back cover for two minutes.
• Alternatively, use a hair dryer or heat gun to soften the adhesive, following linked safety guidelines carefully.

Observe how the back cover adhesive is applied along the frame's edges.

• Note the area where the adhesive meets the camera lenses, as you'll be working nearby.
• Insert your tool carefully and only slightly under the cover near the cameras to avoid damaging them.

Align the suction handle with the center of the back cover's bottom edge.

Hold the handle as close to the edge as possible to avoid damage.

Apply firm pressure to the suction handle until a gap appears between the back cover and frame.

• Use your lifting hand to hold the phone in place with your fingers, or steady the frame with your other hand.

• Be cautious: your phone may be hot during this process.

• Insert a pointed tool, such as an opening pick, into the gap.

Apply heat if the back cover feels stuck during separation.

• Slide the opening pick along the bottom edge to separate the adhesive.

Insert the opening pick into the bottom right corner of the device.

• Work the pick along the right edge, applying gentle pressure to release the adhesive.

Insert the pick 2-3mm into the gap near the camera.

• Work the pick around the top right corner, then continue along the top edge.
• This will help release the adhesive without damaging the cameras.

Insert the opening pick at the top left corner and work it down along the left edge to loosen the adhesive.

Remove the back cover using a suction handle.

If stuck, go around perimeter with an opening pick to separate remaining adhesive.

• Power on phone and test functions before reassembly.
• Turn off phone completely before continuing work.
• Check rear cameras for smudges; wipe clean with a lint-free cloth if necessary.

Apply replacement adhesive to either the frame or the back cover; use cutouts and contours for alignment guidance.

Use the point of a spudger to carefully pry up and disconnect the wireless charging coil press connector.

Keep track of each screw for reassembly.

• Remove six 3.5 mm PH screws with a Phillips screwdriver.
• Then, remove seven more 3.5 mm PH screws using the same tool.

Locate the left side of the loudspeaker and use the point of a spudger to gently pry it up.

• Continue prying until the loudspeaker unclips from its mounting point.
• During reassembly, press firmly around the perimeter of the loudspeaker with your fingers or a tool to securely engage its clips.

Grasp the wireless charging and loudspeaker assembly with both hands.

• Lift upwards slowly.

Pry carefully at the gold arrow markings to avoid damaging the surface-mounted components.

• Identify the corresponding gold arrow on the board for each press connector.
• Use a spudger point to gently pry up and disconnect the battery press connector.

Use a spudger's point to pry up and release the two press connectors on the USB-C board's top edge.

• Alternatively, you can disconnect the cable ends from the motherboard for improved access.
• During reassembly, ensure that both ends of the cables are securely reconnected.

Remove the USB-C board screws using a Phillips screwdriver.

• The screws are 3.2 mm long.
• There are two screws to remove.

Ensure SIM card tray is removed before attempting board removal.

• Spatula point under left USB-C edge and lift gently until it unclips.
• Remove the board while avoiding snagged cables.

Risk of damage if small components are pressed upon during reassembly.

• Keep cables out of the way, holding them up as necessary to insert the board.
• Insert the USB-C board at a slight angle, guiding the port into its recess.
• Press down firmly on the top edge's center to clip the board in place.
