Samsung Galaxy S25 FE USB-C Board Replacement

A charged lithium-ion battery can explode if damaged.

• Allow the battery to drain below 25% before starting this repair.
• Unplug all cables from your phone.
• Power off your phone by holding the side key and volume down button.

Broken back glass can cause injury or complicate disassembly.

• Apply non-overlapping strips of packing tape over cracked glass, covering it completely.
• A single strip should be across the bottom edge, large enough for a suction cup to fit.
• Only apply tape to the glass, not the frame.

Consider wearing safety glasses during this repair to protect your eyes from loose glass fragments.

Improper use of a heat gun can destroy the display and/or battery — follow the linked instructions carefully.

• Secure an iOpener to the bottom edge of the back cover for two minutes, or
• use a hair dryer or heat gun (carefully following linked instructions).

Separate the adhesive from the device frame, referring to the provided picture for guidance.

• Avoid inserting tools near the cameras to prevent damage.

• Insert your tool under the cover only slightly and carefully.

Position the suction handle on the center of the back cover's bottom edge, as near to the edge as feasible.

Apply steady pressure on the suction handle until a gap appears between the back cover and frame.

• Use one hand to hold the phone down with your fingers or steady the frame, being careful as the phone may be hot.
• Pierce the gap with the tip of an opening pick.

Apply heat if the back cover is stuck.

• Use a opening pick to slide along the bottom edge.
• Separate the adhesive with gentle pressure.

Insert an opening pick at the bottom right corner of the device, sliding it upwards along the right edge to loosen the adhesive.

Insert a pick 2-3 mm deep into the gap near the cameras, avoiding damage.

• Work the pick into the top right corner.
• Slide it along the top edge to loosen adhesive.

Insert an opening pick at the top left corner of the device.

• Work the pick downwards along the left edge, applying gentle pressure to break the adhesive seal.

• Lift and remove the back cover using a suction handle.

• If still stuck, re-grip the perimeter with an opening pick to separate any remaining adhesive.

Before sealing: power on your phone and test all functions, then shut down completely.

• Inspect rear cameras for smudges; gently wipe with a clean, lint-free cloth if needed.
• Back cover adhesive should be applied to either the or the back cover. Use cutouts and contours to determine alignment.

Use the pointed end of a spudger to carefully lift and release the wireless charging coil press connector.

Keep track of all screws removed during this repair.

• Remove the wireless charging and loudspeaker assembly using a screwdriver to loosen the fourteen screws.
• Six screws securing the wireless charging coil: 3.5 mm long, screw type unknown.
• Eight screws securing the loudspeaker: 3.5 mm long, screw type unknown.

Ensure each screw is replaced in its original location to avoid damaging your phone.

Insert the point of a spudger into the clip holding the loudspeaker on the left side.

• Lift the loudspeaker away from its mounting point to unclip it.
• During reassembly, press firmly around the perimeter of the loudspeaker with your fingers to engage its clips.

Use both hands to lift and remove the wireless charging and loudspeaker assembly.

Pry at the correct location only, avoiding damage to sensitive components.

• Locate the gold arrow on the board indicating the press connector's correct prying point.
• Use a spudger to carefully pry up and disconnect the battery press connector.

Locate the SIM card tray hole on the bottom edge of your phone.

• Firmly press a SIM eject tool, bit, or straightened paper clip into the hole until the tray ejects.
• A small mic hole is next to the SIM tray. Avoid confusion between the two openings.

Use a spudger to pry up the three press connectors on the top edge of the USB-C board.

• Pry open the two interconnect cable connectors and the fingerprint reader connector.
• (Optional): Disconnect and remove the other ends of the interconnect cables from the motherboard for better access.

When reassembling, reconnect both ends of the interconnect cables if you removed them.

Remove the two 3.5 mm long Phillips screws with a Phillips screwdriver.

Lift the fingerprint cable gently to clear access to the USB-C board.

Remove SIM card tray before attempting board removal.

• Use spudger point to unclip top corners of USB-C board.

Avoid prying against battery — risk of damage and safety hazard.

• Press down firmly on center of board during reassembly to secure.

Be careful not to touch small surface-mounted components when pressing into place.

Remove the USB-C board from the phone by pulling it towards the top.

• During reassembly:
• Ensure the three cables connected to the USB-C board are out of the way, holding them up as needed during insertion.
• Insert the USB-C board at a slight downward angle, guiding the port into its recess.

Make sure the push connectors on the bottom edge are properly seated against the frame to avoid damage.
