Samsung Galaxy S25 Edge Logic Board Replacement

Lithium-ion batteries can catch fire when damaged, so let the phone's battery drain below 25%.

• Power off the phone completely.
• Unplug all cables from the device.

Apply gentle pressure to loosen the back cover from its adhesive.

• Use an iOpener to heat the bottom edge of the back cover for 2 minutes to soften the adhesive.
• As a substitute, use a hair dryer, heat gun, or hot plate to apply targeted heat.

Position the suction handle near the center of the back cover's bottom edge.

Apply suction as close to the edge as possible to avoid damaging the surrounding components.

Hold the suction handle firmly and pull upwards with steady force.

• A small gap should form between the cover and frame.
• Insert the tip of a pick tool into this gap.

Use the provided reference image for guidance when separating the adhesive.

• Separate the left edge adhesive, keeping the pick insertion depth under 3 mm to avoid damage to the wireless charging coil and interconnect cable.
• Repeat this process for the right edge adhesive.

Apply additional heat if necessary and attempt separation again.

• Guide your opening pick along the bottom edge to release the adhesive securing the back cover.

Slide your pick along the entire perimeter of the back cover, separating remaining adhesive.

• Avoid inserting the pick too deeply under the long left and right edges.

Remove the back cover.

Check the perimeter for remaining adhesive and use an opening pick to separate if needed.

• Power on your phone and test functions before reassembly.
• Ensure phone is powered down completely before continuing work.

Inspect rear cameras, wipe clean with lint-free cloth if necessary.

Apply replacement adhesive to either the frame or back cover, using cutouts and contours for alignment.

Prying on the connector may cause damage or injury if done improperly.

• Insert a pointed tool (spudger or opening pick) under the wireless charging assembly press connector.
• Pry up and disconnect the connector from its top edge.

Keep a record of removed screws to ensure accurate reassembly.

• Remove the wireless charging and loudspeaker assembly using a Phillips screwdriver.
• Be aware that there are eleven 2.8 mm long screws to be removed.

Risk of damaging the wireless charging coil or loudspeaker when removing.

• Remove the wireless charging coil and loudspeaker together as one assembly.
• Use angled tweezers to unclip the loudspeaker from its notch on the left edge.
• Reassemble by pressing down firmly around the loudspeaker's perimeter to engage its clips.

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

• Lift the assembly upwards, using a gentle twisting motion.
• Remove the assembly from its original position.

Pry at the correct location indicated by the gold arrow, or risk damaging the board's surface-mounted components.

• Locate the gold arrow corresponding to each press connector on the board.
• Use a spudger to pry up and disconnect the battery press connector at its marked location.

Use the point of a spudger to carefully disconnect the earpiece speaker press connector.

Remove the earpiece speaker using a Phillips screwdriver.

• There are five screws, each 2.8 mm long.

Use a spudger with the flat end to unclip the earpiece speaker from the middle of its lower edge.

• During reassembly, press down firmly around the perimeter of the earpiece speaker.

Remove the earpiece speaker

Insert the pointed tip of a spudger under each connector.

• Pry up to disconnect the screen connector.
• Repeat for the USB-C and interconnect cable connectors.

• Use the point of a spudger to pry up the 5G mmWave antenna connector and front camera press connector.

Remove the rear camera screws using a Phillips screwdriver.

• The screws are approximately 2.8 mm long.

Use a flat-ended spudger to lift the top edge of the logic board.

• Grip the edges and carefully lift the board out, avoiding any cables.

Avoid gripping by the rear cameras to prevent smearing or damage.

• During reassembly, use a spudger to hold cables away from the logic board.

Hold the logic board with the cameras at an angle above the work surface.

• Pry up and disconnect both rear camera press connectors using a spudger point.

Remove the rear cameras from the logic board.

• One or both cameras are available for replacement, depending on your repair.
• During reassembly, compare your new part to the original and remove any plastic liners, adhesive backings, or protective covers as needed.

The thermal paste is prone to denting, so handle with care.

• Use the flat end of a spudger to gently scrape off old thermal paste.
• Apply minimal pressure and do not attempt to remove every last bit of paste.

Avoid direct contact with the phone's screen when cleaning.

• Apply one or two drops of high-concentration isopropyl alcohol (>90%) to a cotton swab.
• Use the cotton swab to gently clean up and remove remaining thermal paste from the vapor chamber, reapplying alcohol as needed.

Avoid touching the delicate film on the logic board.

• Apply a small bead of thermal paste, approximately the size of a grain of rice, to the center of the black film.
