23 steps

Switching off your device
Turn off your device by holding down the power button until the “Power off” option appears.
Use your finger to confirm that you want to shut down your Galaxy S9+ and wait until the screen goes blank.
Removing the back cover
The back cover’s really glued to the chassis. Heat the device evenly with hot air to soften the glue. A temperature of 60 - 80°C should be sufficient. As a rule of thumb, you should still be able to touch your device without it being uncomfortably hot.
The easiest way to loosen the back cover is to use a flat and flexible tool such as the iPlastix or iFlex. You will also need several picks to unstick the back cover all around.
Heat the spot where you start and place a flat tool between the back cover and the frame.
The iPlastix is made of plastic, so it won't scratch the device. On the other hand, it's very soft and tricky to insert.
Be extra careful, the back cover can break very easily. If necessary, apply the heat several times and try again. Removing the back cover might take half an hour. Take a little more time and work carefully to make sure you don't break anything.
Once the tool is inserted, stick a pick into the gap to keep it open. Then run the tool around the entire edge to gradually loosen the glue.
Then heat the next part and insert the picks one by one.
The back cover glue is extra strong on the lower edge.
Once the back cover is loosened, lift it very slightly. The fingerprint sensor underneath the camera is still connected with a cable.
Use a suction cup to lift the glass if you can’t find anywhere to insert the tool
Disconnecting the fingerprint sensor
After detaching the back cover, carefully lift it and disconnect the fingerprint sensor using the spudger.
Then you can completely remove the back cover and set it aside.
Removing the NFC antenna
11 × 3,87 mm Phillips

Remove the screws that attach the upper cover to the display.
The cover is latched onto the case, the lower part of the antenna is lightly glued in place. Slide a flat tool under the latches to disconnect them.
Now remove the antenna.
Disconnecting the battery contact
Battery connector

Using the spudger, carefully disconnect the battery contact from the motherboard.
Information for the charging port replacement guide

Removing the speaker
5 × 3,87 mm Phillips

Remove the screws that attach the speaker to the display and then remove it.
Removing the front camera & sensor

Sensor connector

Disconnect the connectors of the front camera and the sensor.
Then you can pry out the front camera and the sensor out of the chassis and then remove them.
Removing the SIM and microSD card tray
Use the SIM tool to eject the SIM card tray from your device and then remove the tray with your fingers.
Removing the motherboard
Connectors

Using the spudger, carefully disconnect the marked contacts from the logic board.
Now you can carefully remove the motherboard. Make sure it doesn’t get caught on the connectors you already disconnected.
The USB port is still connected to the back of the board. Once you’ve lifted the board, you can use the spudger to disconnect this contact.
Then set the board aside in a safe place.
There's a small plastic pin in the opening of the SIM tray. Make sure it doesn't fall out.
Removing the headphone jack
1 × 3,3 mm Phillips

Unscrew the screw holding the jack in place.
Disconnect the headphone jack’s contact from the PCB. Using the spudger, carefully pry the contact out of the socket.
Remove the headphone jack from the enclosure.

Removing the USB-Board
4 × 3,3 mm Phillips

Remove the marked screws.
Remove the two antenna cables from their guide.
Then you can use the spudger to carefully pry out the board and remove it entirely.
Installing the USB board
4 × 3,3 mm Phillips

Reinstall the USB board.
Make sure the entire flexible cable is flush with the enclosure.
Carefully press the antenna cables back into the appropriate guide using a blunt object such as a pair of tweezers with rounded tips.
Then fasten the screws again.
Installing the headphone output
1 × 3,3 mm Phillips

Put the jack in its position at the lower edge of the enclosure.
Connect the plug contact.
Then fasten it with the appropriate screw.
Installing the motherboard
1 × 3,3 mm Phillips

Connectors

Now you can put the motherboard back in.
First connect the USB port on the back of the board.
Then you can put the board back in the enclosure. Make sure no cables or connectors get stuck under the board.
Fasten the motherboard with the marked screw.
Now connect the marked contacts to the board again.
Inserting the SIM and microSD card tray
Insert the SIM card tray back into your device. Make sure the tray is positioned properly.
Installing the front camera & sensor
Put the front camera and the sensor in the opening at the upper edge of the enclosure and reconnect the connectors.
Installing the speaker
5 × 3,87 mm Phillips

Now put the speaker at the lower end of the enclosure.
Press it gently with your fingers until it clicks into place in the enclosure.
Then reinsert the marked screws.
Connecting the battery
Battery connector

Connect the battery to the motherboard. Press the contact onto the connection on the motherboard until you hear it click into place.
Installing the NFC antenna
11 × 3,87 mm Phillips

Put the cover with the antenna back in the enclosure after hooking it onto the top of the enclosure.
Then press the cover with your fingers until it clicks gently into place all over.
Fasten the phillips screws.
Connect fingerprint sensor
Before attaching the back cover, plug in the fingerprint sensor connector.
Use a plastic tool to reach the connector.
Preparing the backcover
Before you put the back cover back on the case, inspect the adhesive. It should sit evenly on the edge so that the back cover can be placed flush. Remove excess glue if necessary.
Attaching the back cover
Put the back cover back in its original position.
Press the back cover on all over so the glue will stick.
You can also heat your device with hot air and then clamp it or weight it down with a couple books so the glue will stick better.
