Samsung Galaxy S25 Ultra USB-C Board Replacement

Let the Galaxy's battery drain to 25% or less before repair.

• Disconnect all cables from the phone.
• Power off the phone by holding the side key and volume down button.

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

Do not confuse this with the nearby mic hole.

• Remove the ejected SIM card tray.

Cracked back glass can cause injury or complicate disassembly.

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

Do not apply tape to the frame and consider wearing safety glasses during the repair.

Improper heat gun use can damage display & battery.

• Heat an iOpener on the bottom edge of the back cover for 2 minutes.
• Alternatively, use a hair dryer or heat gun to loosen the adhesive.

Follow linked heat gun instructions carefully to avoid damage.

Separate the adhesive from the back cover using the provided picture as a reference.

• Insert your tool carefully under the back cover near the cameras, just slightly for damage prevention.

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

Apply strong, steady force to the suction handle until a gap appears between the back glass and frame.

• Hold the phone down with one hand or stabilize the frame with your other hand.

• Be careful: the phone may be hot.

• Insert an opening pick into the gap.

Apply heat to the back cover if it feels stuck.

• Heat the area with a heat gun or similar tool.
• Try separating the adhesive again.
• Slide the opening pick along the bottom edge to continue separation.

Insert an opening pick at the bottom right corner of the device.

• Slide it along the right edge, working your way up to loosen the adhesive.

Insert the pick just 2-3 mm near each camera.

• Slide the pick up the top right corner and along the top edge, prying up the adhesive.

Insert the opening pick at the top left corner, then work it down the left edge to break apart the adhesive.

Use a suction handle to lift off the back cover.

• If the cover still feels stuck, use an opening pick around the perimeter and separate any remaining adhesive.
• During reassembly:
• Power on your phone and test all functions before sealing it up.

Make sure to power down your phone completely before continuing work.

• Check the rear cameras for smudges and gently wipe them with a clean, lint-free cloth if necessary.

Apply replacement back cover adhesive either to the frame or the back cover, following one of these guides depending on where it's applied.

Insert the point of a spudger between the wireless charging coil press connector, then gently pry up and disconnect it.

Keep track of each screw removed from the wireless charging and loudspeaker assembly.

• Use a Phillips screwdriver to remove ten screws.
• Four screws: wireless charging coil
• Six screws: loudspeaker

Make sure each screw returns to its original position.

Apply heat from an iOpener to the two tabs holding the wireless charging coil for 1 minute.

• The mild adhesive will begin to soften during this time.
• Be prepared to proceed with removal after the adhesive has softened sufficiently.

Handling the battery requires care — risk of leakage or fire.

• Use plastic tools to avoid damage.
• Apply more heat if tabs feel fragile, then try again.

Slide a spudger under the top edge of the upper tab and lift slowly to separate it.

This may need to be repeated several times for complete separation.

Repeat the process from the previous step, but start at the bottom edge and work up.

• Insert the edge guide into the top of the tab assembly.
• Gently pry the lower tab loose from the case, working upwards.

Insert the spudger tip into the right side of the loudspeaker and pry it loose.

• Securely clip the loudspeaker in place by pressing firmly around its perimeter during reassembly.

Hold the wireless charging and loudspeaker assembly firmly with both hands.

• Lift up from the phone body using a gentle prying motion.

Pry only at the gold arrow markings, as prying in the wrong area may damage surface-mounted components.

• Locate the gold arrow marking on the board corresponding to the press connector.
• Use a spudger to carefully pry up and disconnect the battery press connector.

Avoid damaging the USB-C board.

• Insert the point of the spudger under one press connector.
• Pry up to release the connector from its socket.
• Repeat for the second press connector on the opposite edge.

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

• The screws are three in total, each measuring 3.4 mm long.

Remove the SIM card tray before proceeding.

• Insert a spudger under the top right corner of the USB-C board and lift until it unclips.

Make sure cables are clear of snagging points during removal.

• During reassembly, keep cables out of the way and hold them up as needed.
• Insert the USB-C board at a slight angle, guiding the port into its recess.
• The push connectors on the bottom edge must be seated against the frame.

Avoid pressing on small surface-mounted components during assembly.

Firmly press down on the center of the top edge to secure the board in place.
