Introdução
Follow this guide to replace the back cover of your Samsung Galaxy Note9.
O que você precisa
-
-
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.
-
-
-
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.
It takes so much heat that it is concerning that damage might be caused to the internal parts. It is difficult to heat the glue, pull the case apart and insert the pick at same time. May need some more pointers to handle these situations first, to prevent possible damage. Also what about the glue that is heated and then cooled before opening? Does it run inside and cause greater adhesion after it cools? Another thing, the handling may cause the phone to turn back on while working to separate. Don't know that that is of concern.

-
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.
It's extremely easy to crack the back glass when nearing and rounding the corners. It's probably a good idea to soften the adhesive with heat as you go.
Step 5 is NOT "cut through the adhesive", that's steps 5-10. Step 5 is "Begin the careful process of cutting through the adhesive, starting at the right side where you already softened it. Proceed carefully, slowly, and warmly through the following steps."
These comments are spot-on. I never break a phone, and I cracked the back glass following the instructions without seeing these comments first. Heat the back much more than you think you need and go super, super slow.
-
-
-
Starting from the center, cut the adhesive up and down the right side with an opening pick.
-
-
-
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.
There seems to be a lot of glue at the bottom, I broke the glass as I was cutting past the charging port - not sure if it was already fractured or just not enough heat (I used Sellotape so it didn't break up into pieces!)
I think LOTS of heat & patience is the key!
Be very careful around the corners and bottom (probably top too, but I didn't have a problem there). Make sure you've cut in far enough down the side first (go in about 1cm) but less round the corners and work in slowly.

-
Use a heat gun or hair dryer or apply a heated iOpener to the left side of the rear panel for at three minutes 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.
-
-
-
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.
Be VERY patient as you slide the opening picks around the periphery of the glass, and use heat very liberally. Make sure the smooth, clear aspect of the iOpener is against the glass, not the rough black portion.
-
-
-
Separate the right side of the rear cover first.
-
Tilt the cover up along the left edge to expose the fingerprint sensor ribbon cable.
Thought I'd done something wrong here as there wasn't a cable attached to the back - the fingerprint reader hadn't come away with the back, but had stayed with the phone.
Exactly the same experience. Made life a little easier.
Happened to me as well.
-
-
-
Use the tip of a spudger to pry the fingerprint sensor ribbon cable up and out of its socket.
-
-
-
Remove the 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. You don't have to clear out adhesive down to the plastic but larger pieces should be removed.
-
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.
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!

-
Use a heat gun, hair dryer or apply a heated iOpener on the outside of the fingerprint sensor to soften the adhesive underneath. Heat it until it's slightly too hot to touch, as the adhesive is soft and resists tearing.
-
-
-
Remove the fingerprint sensor.
-
Use tweezers to peel off as much adhesive as you can. Then clean off the remaining adhesive with 90% isopropyl alcohol and a lint-free cloth.
The fingerprint sensor I had was much to tight to connect it before the rear glass. After experimenting with the finest tweezers, trying to secure the connector was not possible. Instead I removed the sensor from the glass, secured the connector to the port then lowered the glass over the sensor. Because the sensor body is closer to midline I had enough clearance to make fine adjustments with a pin in order to align it with the rear glass cutout. Other than reversing those steps the rest of this guide was excellent. Good work and successful repair.

Thank you for the Guide
Excellent. Thank you
So where do I get the back panel replacement part?
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.

Just came here to say exactly that. The instructions should be amended to state that: "Get it fully hot and leave it there for at least three minutes solid."
