Introduction

Use this guide to replace the daughterboard on a Samsung Galaxy S6. The daughterboard is home to the headphone jack, LED soft buttons, and the USB charging port. If you're having charging issues or your aux port isn't working, replacing the daughterboard is a good place to start.

This guide involves removing the rear glass. Removing the rear glass destroys the adhesive holding it in place. Follow this guide to reinstall the rear glass.

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

    • Press to eject the SIM card tray.

    • Don't press too hard or you may damage the SIM card tray.

  2. Remove the SIM card tray from the phone.
    • Remove the SIM card tray from the phone.

  3. We recommend that you clean your microwave before proceeding, as any nasty gunk on the bottom may end up stuck to the iOpener. Place the iOpener in the center of the microwave.
    • We recommend that you clean your microwave before proceeding, as any nasty gunk on the bottom may end up stuck to the iOpener.

    • Place the iOpener in the center of the microwave.

    • For carousel microwaves: Make sure the plate spins freely. If your iOpener gets stuck, it may overheat and burn.

  4. Heat the iOpener for thirty seconds.
    • Heat the iOpener for thirty seconds.

    • Throughout the repair procedure, as the iOpener cools, reheat it in the microwave for an additional thirty seconds at a time.

    • Be careful not to overheat the iOpener during the repair. Overheating may cause the iOpener to burst.

    • Never touch the iOpener if it appears swollen.

    • If the iOpener is still too hot in the middle to touch, continue using it while waiting for it to cool down some more before reheating. A properly heated iOpener should stay warm for up to 10 minutes.

  5. Remove the iOpener from the microwave, holding it by one of the two flat ends to avoid the hot center.
    • Remove the iOpener from the microwave, holding it by one of the two flat ends to avoid the hot center.

    • The iOpener will be very hot, so be careful when handling it. Use an oven mitt if necessary.

  6. Opening your phone will compromise its waterproof seals. Have replacement adhesive ready before you proceed, or take care to avoid liquid exposure if you reassemble your phone without replacing the adhesive. If your glass is shattered, put packing tape over the entire panel to hold it together during the removal process.

    • If your glass is shattered, put packing tape over the entire panel to hold it together during the removal process.

    • Lay the heated iOpener over the rear panel for about two minutes to loosen the adhesive around the edge of the glass.

    • You may need to reheat and reapply the iOpener several times to get the phone warm enough. Follow the iOpener instructions to avoid overheating.

    • Shift the iOpener to heat the remaining section of the panel for another two minutes.

    • A hair dryer, heat gun, or hot plate may also be used, but be careful not to overheat the phone—the OLED display and internal battery are both susceptible to heat damage.

  7. Once the rear glass is 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 rear glass, and insert an opening pick into the gap. Optionally, once the pick is inserted, you can add a few drops of isopropyl alcohol into the gap to help weaken the adhesive in the following steps.

Step 41

I could not find any led cables... after the repair the led soft keys work and vibrate but do not light up... anyway to fix this problem? Fixing g925a

It seems like you've damaged the Flex oder the Button itself. If youve allready checked the connection to Motherboard, then you need to replace the Daughterboard to solve the issue

Patrick -

For step 41

I could not find and led cables to remove... and after there repair the led light forsaken the soft keys do not light up but they do work and vibrate... what should I do?

I would definitely recommend heating and prying before carrying out step 17. There is a lot of glue holding the frame together and not heating and prying could easily lead to screen damage.

STEP 30 - What about the glue between the plastic frame and display assembly. Is there a product to use to glue it up again?
