    • Remove the SIM card tray.

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

  3. Samsung Galaxy Note9 Charging Assembly Replacement, Apply a heated iOpener: étape 3, image 1 de 1
    • Power off your phone before beginning disassembly.

    • Use a hairdryer, a heatgun, or prepare an iOpener and apply it to the right edge of the back of the phone for about a minute to soften the adhesive underneath.

    If using an iOpener it will need to be fully heated and set on for at least 5 minutes. You’ll know the phone is hot enough when its almost too hot to touch.

  4. Samsung Galaxy Note9 Charging Assembly Replacement, Insert an opening pick: étape 4, image 1 de 3 Samsung Galaxy Note9 Charging Assembly Replacement, Insert an opening pick: étape 4, image 2 de 3 Samsung Galaxy Note9 Charging Assembly Replacement, Insert an opening pick: étape 4, image 3 de 3
    • Apply a suction handle to the back cover.

    • Lift with a suction handle to create a gap between the back cover and the frame of the phone.

    • Insert an opening pick into the gap.

    • If the glass is badly cracked, cover it in packing tape to create a surface for the suction cup to adhere to.

    • If the adhesive won't budge, apply more heat, not excessive force. Too much force could break the glass.

  5. Samsung Galaxy Note9 Charging Assembly Replacement, Cut through the adhesive: étape 5, image 1 de 1
    • Note that there is more adhesive along the top edge and around the camera bezel than around the rest of the phone.

    • Cut carefully around the left edge near the fingerprint sensor or you risk damaging the ribbon cable inside.

  6. Samsung Galaxy Note9 Charging Assembly Replacement, Slide the opening pick: étape 6, image 1 de 3 Samsung Galaxy Note9 Charging Assembly Replacement, Slide the opening pick: étape 6, image 2 de 3 Samsung Galaxy Note9 Charging Assembly Replacement, Slide the opening pick: étape 6, image 3 de 3
    • Starting from the center, cut the adhesive up and down the right side with an opening pick.

    • Do not insert the pick more than halfway into the phone when cutting near the fingerprint sensor or cameras, or you risk damaging internal components.

  7. Samsung Galaxy Note9 Charging Assembly Replacement: étape 7, image 1 de 3 Samsung Galaxy Note9 Charging Assembly Replacement: étape 7, image 2 de 3 Samsung Galaxy Note9 Charging Assembly Replacement: étape 7, image 3 de 3
    • Leave an opening pick in the upper-right corner.

    • Use another opening pick to cut the adhesive around the bottom-right corner.

    • Leave that opening pick in the phone.

    • Use an iOpener, hair dryer, or heat gun to apply more heat as needed where you are cutting the adhesive.

  8. Samsung Galaxy Note9 Charging Assembly Replacement: étape 8, image 1 de 1
    • Use a heat gun or hair dryer or apply a heated iOpener to the left side of the rear panel for about a minute to soften the adhesive underneath.

    If using an iOpener it will need to be fully heated and set on for at least 5 minutes. You’ll know the phone is hot enough when its almost too hot to touch.

    • Insert an opening pick into the lower-left corner of the rear panel.

    • Using another opening pick, cut the adhesive along the left edge of the rear panel.

    • Do not insert an opening pick in more than half way on the left edge near the fingerprint sensor or you may damage the ribbon cable inside.

    • It is fine if opening picks fall out as the back cover becomes separated.

  10. Samsung Galaxy Note9 Charging Assembly Replacement: étape 10, image 1 de 3 Samsung Galaxy Note9 Charging Assembly Replacement: étape 10, image 2 de 3 Samsung Galaxy Note9 Charging Assembly Replacement: étape 10, image 3 de 3
    • Using the inserted opening pick, carefully cut the adhesive around the upper-left corner of the rear panel.

    • Finally, cut the last of the adhesive along the top of the phone.

    • Use an iOpener, hair dryer, or heat gun to apply more heat as needed where you are cutting the adhesive.

  11. Samsung Galaxy Note9 Charging Assembly Replacement: étape 11, image 1 de 2 Samsung Galaxy Note9 Charging Assembly Replacement: étape 11, image 2 de 2
    • Separate the right side of the rear cover first.

    • Tilt the cover up along the left edge to expose the fingerprint sensor ribbon cable.

    • Do not pull out the fingerprint sensor ribbon cable yet.

  12. Samsung Galaxy Note9 Charging Assembly Replacement, Disconnect the fingerprint sensor: étape 12, image 1 de 2 Samsung Galaxy Note9 Charging Assembly Replacement, Disconnect the fingerprint sensor: étape 12, image 2 de 2
    • Use the tip of a spudger to pry the fingerprint sensor ribbon cable up and out of its socket.

  13. Samsung Galaxy Note9 Charging Assembly Replacement: étape 13, image 1 de 1
    • Remove the back cover.

    • To install a back cover:

    • Use tweezers to peel away any remaining adhesive from the phone's chassis. Then clean the adhesion areas with high concentration isopropyl alcohol (at least 90%) and a lint-free cloth to prep the surface for the new adhesive.

    • Turn on your phone and test your repair before installing new adhesive and resealing the phone.

    • Carefully apply the new adhesive to the back cover, then line up one edge of the glass against the phone chassis and firmly press the glass into the phone.

    • Alternatively, 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 glue is usually more than strong enough to hold.

    I am installing a new backplate (this is my first repair; I was CERTAIN that I would crack the back glass, and I was NOT wrong) but I’m not sure how tweezers are meant to remove gooey adhesive! I simply used the blue plastic pry tool as a scraper and gently rolled up the goo. Maybe the glue is different because I have a refurbished phone? That may also explain why I had so much trouble with Step 1. Hope that this helps!

How do I put the back back on?

William Eustis - Réponse

Hey William, thanks for the question! Check out the second bullet on step 13: To install a back cover:

Sam Omiotek -

Excellent guide.

After reassembling to step 17( reconnecting the battery) I tried powering on the phone. Nothing happened. I connected to a charger,, the phone vibrated and the red blinking light appeared. I left the phone connected to the charger for an hour, tried to power on and nothing happened. I checked to make sure all the connections were tight, but to no avail. I tried a soft reset, but that didn’t work either. Any idea what I did wrong?

B Rich - Réponse

Thank you!

Since there are signs of life when you turn on/charge the phone, but nothing on screen, here’s what I would try:

1. Disconnect the charger

2. Disconnect the battery cable from the motherboard

3. Disconnect the display cable from the motherboard

4. Reconnect the display cable

5. Reconnect the battery cable

6. Power on to test

If that does not fix it, another cable may not be properly connected. This sometimes prevents certain phones from powering on. Otherwise the display connector may have been damaged during the repair.

Sam Omiotek -

The phone definitely is charging and previously set alarms go off on schedule, but screen stays black.

Is there a way to check the integrity of the ribbon cables?

This guide was awesome! Definitely helped me get through the process.
