Samsung Galaxy S6 Daughterboard Replacement - Samsung Galaxy S6

Step 1 | SIM Card

Do not press too hard, as it may damage the SIM card tray.

Insert a paper clip or SIM eject tool into the hole in the SIM card slot on the power button side.
Press to eject the SIM card tray.

Step 2

Remove the SIM card tray.

Step 3 | iOpener Heating

Any debris on the bottom of the microwave can stick to the iOpener.

Clean the microwave thoroughly before proceeding.

Place the iOpener in the center of the microwave.
For carousel microwaves, ensure the plate spins freely to prevent overheating and potential burns.

Step 4

Never touch a swollen iOpener — risk of thermal burn.

Heat the iOpener in the microwave for 30 seconds, adjusting time based on your device's wattage.
The iOpener is ready when it's just too hot to touch lightly.
Reheat as needed throughout the repair: 30 seconds at a time in the microwave.

Do not overheat the iOpener; overheating may cause bursting, and temperatures should not exceed 100°C (212°F).

Use it while warm for up to 10 minutes; reheat if still too hot in the middle.

Step 5

Be extremely cautious when removing the iOpener from the microwave as it may still be extremely hot.

Hold the iOpener by one of its flat ends to avoid direct contact with the hot center.
Wear an oven mitt if necessary for added protection against burns when handling the iOpener.

Step 6 | Alternate iOpener heating method

Fill a pot with enough boiling water to submerge an iOpener.

Turn off the heat.
Submerge an iOpener in the hot water for 2-3 minutes.

The iOpener will be very hot, use tongs to handle and hold only by the end tabs.

Dry the iOpener thoroughly with a towel.

Reheat in boiling water for 2-3 minutes if necessary.

Step 7 | Rear Glass

Opening your phone will compromise its waterproof seals.

Prepare replacement adhesive beforehand.

If reassembling without new adhesive, exercise caution around liquids.

If glass is shattered, secure the panel with packing tape during removal.

Apply a heated iOpener to the rear panel for 2 minutes, focusing on the edge of the glass.

You may need to reheat and reapply the iOpener multiple times to achieve optimal temperature.

Follow iOpener instructions to avoid overheating.

Using alternative heat sources: be cautious not to overheat, as OLED display & internal battery are susceptible to damage.

A hair dryer, heat gun, or hot plate can be used; apply for 2 minutes per section.

Step 8

Heat the rear glass until it's hot to the touch.
Apply a suction cup near the bottom edge of the glass.
Lift on the suction cup to create a small gap underneath the glass, then insert an opening pick into the gap.

Add a few drops of isopropyl alcohol to the gap if needed for further adhesive weakening.

Step 9

Slide the pick along the bottom edge of the phone to slice through the adhesive.

Leaving the pick inserted can help prevent re-adhesion of the separated glue.

Re-heat the rear glass as needed, so the glue doesn't harden.
Take a second pick and proceed to the next step with it.

Step 10

Insert an opening pick under each uncut edge.

Perform the heating and cutting procedure for all remaining edges.
Be cautious not to remove the existing picks, as this will reseal the adhesive.

Step 11

Insert an opening pick into the adhesive and gently pry it loose.
Once free, carefully lift out the rear glass.

Step 12

Remove remaining adhesive from phone's chassis with tweezers.

Clean adhesion areas with isopropyl alcohol (90%+) and a lint-free cloth, swiping in one direction only.
Peel new rear glass adhesive backing, aligning one edge to phone chassis, and press firmly onto phone.

If reinstalling old rear glass or using pre-adhesive glass, refer to this guide for instructions.

Step 13 | Midframe Assembly

Remove the thirteen 3.5mm Phillips #00 screws holding the midframe in place.

Step 14

Eject the SIM card tray before proceeding.

Grasp the edge of the midframe assembly firmly.
Lift up on the midframe while pushing down on the battery.
Avoid snagging the audio jack or charging port during separation.

Be cautious not to insert the opening pick between the glass and display.

Separate the top of the midframe using an opening pick around the edges.
Remove the top of the midframe first to avoid damaging the headphone jack.

If necessary, heat and apply an iOpener to soften display adhesive for easier separation.

Step 15

Separate the midframe assembly from the rest of the phone by lifting it upwards.

Step 16 | Disassembling Samsung Galaxy S6 Battery Connector

Disconnect the battery connector from its socket using the flat end of a spudger.

Step 17 | Motherboard Assembly

Disconnect the Bluetooth and Wi-Fi antenna cable from the motherboard socket using the pointed edge of a spudger.

Step 18

Disconnect the home button connector with the flat end of the spudger.

Step 19

Disconnect the display assembly cable from the motherboard using the flat end of a spudger.

Step 20

Locate and gently pull away the earpiece speaker assembly cable from its connection on the motherboard.

Step 21

Do not fully remove the motherboard — it's still connected to the daughterboard.

Lift the camera-side end of the motherboard to separate it from the display frame.
Move ribbon cables out of the way as needed.
Verify that all connections are fully disconnected and not caught on any cables.

Check for ribbon cable obstructions if the board is hard to lift.

Step 22

Insert the flat end of a spudger under the daughterboard ribbon cable connector and gently pry it loose.

Grip the spudger firmly with your fingers.
Pry upward at the connector until it releases from its socket.

Step 23 | Screen

Apply clear tape over cracked glass to prevent further damage.

Reheating the iOpener may be necessary for effective heating.

Lay the iOpener across the display and wait two minutes.
Shift the iOpener to the other half of the screen, reheating as needed.

Follow the iOpener instructions to avoid overheating the device.

Step 24

Insert the opening pick in the battery-side edge of the phone at an upward angle, between the frame and display.

Incorrect placement may cause the pick to be visible through the glass.

Verify a gap has formed between the display frame and assembly.
If the pick is visible, remove it and restart the process.

Step 25

Slide a pick down the edge of the display to separate the adhesive underneath.
Stop cutting at the daughterboard to avoid damaging the capacitive button.

If cutting becomes difficult, reheat and reapply the iOpener.

Leave the pick in place after cutting the adhesive to prevent display re-adhesion.

Step 26

Do not insert the opening pick more than 0.25 inches (~6mm) or risk damage to the home button.

Slide the pick along the bottom edge of the phone, starting at the headphone jack.
Continue sliding the pick past the charging port, but not too far.

Step 27

The button's ribbon cable is fragile and prone to tearing; keep it in sight as you insert the pick.

Insert an opening pick ~0.5 inches (~12mm) under the display, near the headphone jack.
Apply more heat if the pick is hard to insert or the cable starts to stretch.
Leave the pick in place to prevent the button from re-adhering to the display.

If either the capacitive buttons or ribbon cables are damaged, you can replace the daughterboard assembly with new capacitive buttons.

Step 28

Insert an opening pick 0.5 inches (~12mm) below the opposite bottom corner of the display.

Monitor the ribbon cable closely as you insert the pick; it is prone to tearing.
If the pick resists insertion or the cable begins to stretch, apply additional heat.
Leave the pick in place to prevent the button from re-bonding to the display.

Step 29

Insert an opening pick at the phone's side, away from the battery.

Separate the adhesive along the length of the phone.
Leave the pick in place to prevent re-adhesion.

Step 30

Slide a pick along the top of the phone, toward the vibrator.
Pull the pick out slightly to clear the earpiece speaker grille.

Step 31

Cutting adhesive may cause damage or injury.

Use a opening pick to gently pry the battery side of the frame away from the display.
If separation is difficult, use an opening pick to cut any remaining adhesive.
Reheat and reapply an iOpener if cutting is hard or the adhesive remains stubborn.

Do not remove the display yet — the display cable is still threaded through the frame.

Step 32

Route the display's flex cable through the corresponding hole in the frame.

Ensure the cable passes completely through for proper separation of the right display edge.

Step 33

Removing old adhesive residue is crucial to ensure proper installation of the new display.

Remove all old adhesive from the frame using a gentle scraping motion, taking care to extract any small glass fragments.

Failing to remove glue and glass remnants may cause display damage or improper mounting.

Thoroughly clean adhesion areas with 90% (or higher) isopropyl alcohol and a lint-free cloth or coffee filter, swiping in one direction only.

A bent frame or remaining debris may damage the new display; consider replacing the frame if necessary.

Apply custom-cut double-sided tape to the back of the screen and feed the display cable through the frame.
Align the screen, then carefully press it into place to ensure secure mounting.

Step 34 | Daughterboard

Remove the 3.0mm Phillips #00 screw holding the daughterboard to the display frame.

Step 35

Flip the display frame over so the home button is facing you.

Gently lift the LED cable off the display frame — risk of damaging delicate cables.

Insert the pointed edge of the spudger into the groove next to the right soft button LED cable.

Step 36

Insert spudger into the groove above left soft button LED cable.

Lift the left soft button LED cable off the plastic frame.

Step 37

Turn the frame over and gently lift the daughterboard to separate it from the display frame.
