Introduzione

Follow this guide to remove and replace the motherboard in the Galaxy S20 Plus.

You'll need replacement adhesive in order to complete this repair.

  1. Insert a SIM card eject tool, bit, or a straightened paperclip into the hole on the SIM tray, located at the top edge of the phone next to the plastic antenna band. If you inserted the tool into the other hole, don't worry—the microphone and the ingress gasket are mounted out of harm's way.

    • If you inserted the tool into the other hole, don't worry—the microphone and the ingress gasket are mounted out of harm's way.

    • Press in firmly to eject the tray.

  2. Remove the SIM card tray. The SIM card will fall out of the tray easily.
    • Remove the SIM card tray.

    • The SIM card will fall out of the tray easily.

    • When you reinsert the SIM card, ensure that it is in the proper orientation relative to the tray.

    • A thin rubber gasket around the SIM tray provides water and dust protection. If this gasket is damaged or missing, replace the gasket or the entire SIM tray to protect your phone's internal components.

  3. Unplug and power off your phone before you begin.
    • Unplug and power off your phone before you begin.

    • Heat an iOpener and apply it to the back cover's bottom edge for two minutes.

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

  4. Apply a suction cup to the back of the phone, as close to the center of the bottom edge as possible. If your display is badly cracked, covering it with a layer of clear packing tape may allow the suction cup to adhere. Alternatively, very strong tape may be used instead of the suction cup. If all else fails, you can superglue the suction cup to the broken glass. Pull on the suction cup with strong, steady force to create a gap between the back cover and the frame.

    • Pull on the suction cup with strong, steady force to create a gap between the back cover and the frame.

    • Insert the point of an opening pick into the gap.

    • Due to tight tolerances, this may take multiple attempts of reheating with the iOpener and separating with the suction cup before you get it right.

    • If you are having trouble creating a gap, apply more heat to the edge and try again.

    • Do not apply excessive force with the pick, or you risk cracking the back cover glass.

  5. Slide the pick back and forth along the bottom edge to slice through the adhesive. Do not attempt to cut the adhesive near the corners of the phone where the glass is curved or you risk cracking the glass panel. Leave your opening pick in the seam to prevent the adhesive from resealing.

    • Pull on the suction cup with strong, steady force to create a gap between the back cover and the frame.

    • Insert the point of an opening pick into the gap.

    • As the glass on this edge is curved, you won't be able to insert this pick very far. As long as the very tip of the pick is underneath the glass's edge, you will be able to proceed.

    • Due to tight tolerances, this may take multiple attempts.

    • If you are having trouble creating a gap, apply more heat to the edge and try again.

    • You can try also applying a few drops of high concentration (over 90%) isopropyl alcohol into the seam to help loosen the adhesive.

    • Do not apply excessive force with the pick, or you risk cracking the back cover glass.

  8. Once the pick is underneath the glass's edge, tilt it downward and insert it further to fully separate the back cover's adhesive. Once the pick is underneath the glass's edge, tilt it downward and insert it further to fully separate the back cover's adhesive.
    • Once the pick is underneath the glass's edge, tilt it downward and insert it further to fully separate the back cover's adhesive.

  9. Slide the pick all along the left edge of the phone to separate the back cover's adhesive. Take care when sliding across the ridge in the frame surrounding the volume and power buttons—the cutout in the glass may make it more prone to cracking. Leave your pick under the left edge of the glass to prevent the adhesive from resealing.

    • Insert the point of an opening pick into the gap.

    • Like with the previous edge, you will need to tilt the opening pick downward to fully insert it underneath the back cover.

  12. Slide the pick all along the right edge of the phone to separate the back cover's adhesive. Leave your pick under the right edge of the glass near the top of the device to prevent the adhesive from resealing. As you do this, the back cover may release one or both of the other picks and allow them to fall free. If this occurs, set the pick(s) aside as the bottom edge shouldn't reseal from this point onward.

  14. The glass near the corners of the back cover is curved and very susceptible to cracking. Be gentle during this step to prevent damaging your back cover. Gradually slide the pick from the right edge of the device around the top right corner. Continue slicing along the top edge all the way around to the left edge to fully separate the back cover adhesive.

Hi Tarun. Thank you so much for the guide! I was wondering if you know where I can buy the motherboard since mine is damaged. Thank you!

Sebastian - Replica

That is very comprehensive. Full of photos and instructions

Saurabh Jain - Replica

Tarun never answered Sebastian’s questions, how much the motherboard costs… I have the same problem… got just out of the warranty, shoot.

Mass Abedi - Replica

is the internal storage actually also located on the motherboard? Means, if I change the motherboard, do I loose everything?
