Step 1: Power Off and Remove the SIM Tray
Begin by completely powering down your Samsung Galaxy S25 to prevent electrical shorts.
Use a SIM ejector tool to remove the SIM card tray from the bottom edge of the phone.
This step is crucial to avoid damaging the internal motherboard pins during disassembly.

Step 2: Heat the Back Glass
Apply heat to the edges of the rear glass panel using a heat gun or thermal pad.
Keep the temperature around 80 degrees Celsius for a few minutes to soften the factory waterproof adhesive.
Wear safety glasses in case the cracked glass splinters while you work.

Step 3: Slice the Rear Adhesive
Place a suction cup near the bottom edge of the back glass and pull up gently to create a tiny gap.
Insert a plastic opening pick into this gap and carefully slide it around the perimeter.
Work slowly to cut through the adhesive without inserting the pick too deeply, which could damage internal antennas.

Step 4: Remove the Wireless Charging Coil
Once the back glass is off, locate the upper motherboard shield and the wireless charging coil.
Unscrew the Phillips #00 screws securing the plastic bracket in place.
Gently unclip the bracket and lift the charging pad away, being careful not to tear the delicate NFC ribbon cable.

Step 5: Disconnect the Battery
Safety is the top priority, so you must disconnect the power source immediately.
Use a plastic nylon spudger to pry up the battery connector from the motherboard.
This eliminates the risk of short circuits while you handle other metallic components.

Step 6: Disconnect the Display Flex Cable
Locate the main display ribbon cable connecting the screen to the motherboard.
Use your nylon spudger to gently pop the connector off its socket.
If your replacement screen does not include a new frame, you will also need to disconnect the auxiliary interconnect cables.

Step 7: Remove the Old Screen
Apply heat to the front of the device to soften the adhesive holding the broken OLED panel to the frame.
Use a suction cup and plastic picks to slice through the front adhesive.
If you are using a screen with an included frame, you will instead need to transfer the motherboard, battery, and lower board to the new housing.

Step 8: Clean the Frame and Apply Adhesive
Thoroughly clean any leftover adhesive or glass shards from the bare frame using high concentration isopropyl alcohol.
A clean surface is mandatory for the new adhesive to bond properly.
Apply your custom cut adhesive gaskets to the perimeter of the frame.

Step 9: Install the New Screen
Thread the new display flex cable through the frame routing hole and press the new screen firmly into the adhesive.
Reconnect the display flex cable and the battery to the motherboard.
Power on the device temporarily to test touch functionality and display quality before final sealing.

Step 10: Reassemble and Seal the Device
Once testing is successful, reinstall the wireless charging coil and secure it with the Phillips screws.
Apply fresh adhesive to the back glass, align it carefully, and press it firmly into place.
Apply steady pressure with clamps or heavy books for about an hour to ensure a watertight seal.
