Samsung Galaxy S10e Motherboard Replacement

What you need

  1. Samsung Galaxy S10e Motherboard Replacement, Eject the SIM/Micro SD tray: step 1, image 1 of 2 Samsung Galaxy S10e Motherboard Replacement, Eject the SIM/Micro SD tray: step 1, image 2 of 2
    • Insert a SIM card eject tool, bit, or a straightened paperclip into the small hole in the SIM card tray.

    • If you accidentally inserted the SIM eject tool into a different hole, don’t worry! You most likely haven’t damaged anything.

    • Press firmly to eject the tray.

  2. Samsung Galaxy S10e Motherboard Replacement, Remove the SIM/Micro SD tray: step 2, image 1 of 2 Samsung Galaxy S10e Motherboard Replacement, Remove the SIM/Micro SD tray: step 2, image 2 of 2
    • Pull the tray straight out to remove it.

  3. Samsung Galaxy S10e Motherboard Replacement, Heat the back cover: step 3, image 1 of 1
    • 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.

    • Turn your phone off completely before you begin this repair.

    • Prepare an iOpener and heat the back of the phone along the right edge for about two minutes. This will help soften the adhesive securing the back cover.

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

    • 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.

  4. Samsung Galaxy S10e Motherboard Replacement, Prepare to slice the adhesive: step 4, image 1 of 2 Samsung Galaxy S10e Motherboard Replacement, Prepare to slice the adhesive: step 4, image 2 of 2
    • In the following steps, you'll be cutting through the adhesive securing the back cover.

    • The adhesive is laid out as seen in the first image, which shows the inside of the cover after it has been removed.

    • As seen from the outside of the phone, you'll be slicing through the adhesive in the highlighted areas.

    • The adhesive is the thinnest on the right side of the phone, just below the Bixby button.

  5. Samsung Galaxy S10e Motherboard Replacement, Secure a suction cup: step 5, image 1 of 2 Samsung Galaxy S10e Motherboard Replacement, Secure a suction cup: step 5, image 2 of 2
    • Secure a suction cup to the back cover, as close to the heated edge as possible, just under the Bixby button where the adhesive is thinnest.

    • The suction cup will not make a good seal on the curved portion of the glass, so avoid putting it on the very edge.

    • If the phone's back cover is cracked, the suction cup may not stick. Try lifting it with strong tape, or superglue the suction cup in place and allow it to cure so you can proceed.

  6. Samsung Galaxy S10e Motherboard Replacement, Create an opening gap: step 6, image 1 of 3 Samsung Galaxy S10e Motherboard Replacement, Create an opening gap: step 6, image 2 of 3 Samsung Galaxy S10e Motherboard Replacement, Create an opening gap: step 6, image 3 of 3
    • Prop up the heated edge of the phone on something that is about 0.5 inches (13 mm) thick. This will angle the phone so that the opening tool is easier to insert.

    • Lift the back cover's right edge with your suction cup, opening a slight gap between the back cover and the frame.

    • This may require a significant amount of force. If you have trouble, apply more heat to further soften the adhesive, and try again. The adhesive cools very fast, so you may need to heat it repeatedly.

    • If you're using an iOpener, follow the heating instructions to avoid overheating it, or the gel pack may burst.

    • Press the edge of an opening tool into the gap.

    • The rear glass can break if you use too much force or attempt to pry with metal tools.

  7. Samsung Galaxy S10e Motherboard Replacement: step 7, image 1 of 3 Samsung Galaxy S10e Motherboard Replacement: step 7, image 2 of 3 Samsung Galaxy S10e Motherboard Replacement: step 7, image 3 of 3
    • Slide the opening tool along the right edge of the phone to slice through the adhesive securing the back cover.

  8. Samsung Galaxy S10e Motherboard Replacement: step 8, image 1 of 2 Samsung Galaxy S10e Motherboard Replacement: step 8, image 2 of 2
    • Insert an opening pick into the edge next to the opening tool. Leave the pick here to prevent the separated glue from re-adhering.

  9. Samsung Galaxy S10e Motherboard Replacement: step 9, image 1 of 1
    • Apply a heated iOpener to the top edge of the phone for two minutes.

  10. Samsung Galaxy S10e Motherboard Replacement: step 10, image 1 of 3 Samsung Galaxy S10e Motherboard Replacement: step 10, image 2 of 3 Samsung Galaxy S10e Motherboard Replacement: step 10, image 3 of 3
    • Insert an opening pick near the top right corner of the phone and slide it around the corner and across the top edge of the phone.

    • The glued area is larger here, so you'll need to insert your pick farther into the phone to separate it.

    • Leave the opening pick in place to prevent the adhesive from re-adhering.

  11. Samsung Galaxy S10e Motherboard Replacement: step 11, image 1 of 1
    • Apply a heated iOpener to the left edge of the phone for two minutes.

  12. Samsung Galaxy S10e Motherboard Replacement: step 12, image 1 of 3 Samsung Galaxy S10e Motherboard Replacement: step 12, image 2 of 3 Samsung Galaxy S10e Motherboard Replacement: step 12, image 3 of 3
    • Insert a new opening pick near the top left corner and slide it along the left edge of the phone.

    • Again, leave the opening pick in place in the left edge of the phone to prevent the adhesive from resealing.

  13. Samsung Galaxy S10e Motherboard Replacement: step 13, image 1 of 1
    • Apply a heated iOpener to the bottom edge of the phone for two minutes.

  14. Samsung Galaxy S10e Motherboard Replacement: step 14, image 1 of 3 Samsung Galaxy S10e Motherboard Replacement: step 14, image 2 of 3 Samsung Galaxy S10e Motherboard Replacement: step 14, image 3 of 3
    • Insert an opening pick near a bottom corner of the phone, and slide it along the bottom edge of the phone to separate the adhesive there.

    • The glued area is larger here, so you'll need to insert your pick farther into the phone to fully separate it.

  15. Samsung Galaxy S10e Motherboard Replacement: step 15, image 1 of 3 Samsung Galaxy S10e Motherboard Replacement: step 15, image 2 of 3 Samsung Galaxy S10e Motherboard Replacement: step 15, image 3 of 3
    • Use the opening picks to very carefully pry up the back cover.

    • If you encounter any resistance, stop prying and use an opening pick to cut any remaining adhesive.

    • Remove the back cover.

  16. Samsung Galaxy S10e Motherboard Replacement: step 16, image 1 of 1
    • Follow this guide to reinstall the back cover and replace the adhesive.

    • Be sure to turn on your phone and test your repair before installing new adhesive and resealing the phone.

    • If desired, you may reinstall the back cover without replacing the adhesive. Remove any large chunks of adhesive that might prevent the back cover from sitting down flush. After installation, heat the back cover and apply pressure to secure it. It won't be waterproof, but the leftover adhesive is usually more than strong enough to hold.

  17. Samsung Galaxy S10e Motherboard Replacement, Remove the midframe: step 17, image 1 of 1
    • Remove the eight 3.9 mm Phillips screws securing the upper midframe to the phone.

  18. Samsung Galaxy S10e Motherboard Replacement: step 18, image 1 of 2 Samsung Galaxy S10e Motherboard Replacement: step 18, image 2 of 2

  19. Samsung Galaxy S10e Motherboard Replacement: step 19, image 1 of 2 Samsung Galaxy S10e Motherboard Replacement: step 19, image 2 of 2
    • Insert the point of a spudger in the small cutout on the right edge of the plastic part of the upper midframe, near the Bixby button.

    • Use the point of the spudger to pry the midframe up from the phone chassis.

  20. Samsung Galaxy S10e Motherboard Replacement: step 20, image 1 of 1
    • Lift the midframe by the plastic section and remove it from the phone.

replacement mother board

Great job.

After a screen replacement (with chasis included so basically was a board replacement ) I got a really bad cell signal. Any tips about it ?

Hi Carlos,

Check if the black plastic loudspeaker assembly is fully clipped into the frame. The loudspeaker has a few silver antenna lines that connect to the motherboard with spring clips. If it doesn't make good contact, your signal may suffer.
