To loosen the back cover, use a heat gun or an ordinary hair dryer. Warm glue is easier to loosen, allowing you to remove the back cover. 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.

1. Heat the spot where you start and place a suction cup on the bottom of the back cover.
2. Press a flat tool between the back cover and the frame and pull on the suction cup.

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.

1. 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.
2. 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 glass is loosened everywhere, you should only lift it slightly, because the fingerprint sensor, which is located under the camera, still connects the back glass and the circuit board with a very short cable. You will loosen this in the next step.

1. After detaching the back cover, carefully lift it and disconnect the fingerprint sensor using the spudger.
2. Then you can completely remove the back cover and set it aside.

• 10 × 4.0 mm Phillips

Then remove all the equally long Phillips screws from the logic board cover and store them together.

This phone has only two different screw lengths. If some screws don't come off immediately, you can also use a pair of tweezers.

1. The logic board cover with the NFC tag is latched in at the top.
2. Pry it up a little and then take it out.

• Battery connector

1. Now the battery connector is free.
2. To avoid short circuits during the repair, disconnect the battery.

1. Now remove the SIM tray.
2. The best way is to use a SIM tool or a paper clip.
3. Then pull out the SIM tray.

• Connector
• Antenna Plug

1. Now disconnect the different plugs from the logic board.
2. Twist the spudger gently. Don't use it like a crowbar, or you may damage the logic board.
3. There are small parts next to the connectors that break easily.
4. Then disconnect the button plugs of the antenna cables.
5. Grab the cable with the tweezers, not on the plug itself.
6. Disconnect the plug with a twist of the tweezers.

• 1 × 3.4 mm Phillips

1. Now remove the single screw on the logic board.
2. Before removing the logic board, make sure that all connectors are bent aside and don't get stuck.
3. The bottom side of the logic board is still connected to the USB board. Fold up the logic board and flick off the connector using a spudger.
4. Then put the logic board aside.

1. Disconnect the rear camera’s contact from the bottom of the motherboard.
2. The camera is lightly glued to the board so you have to carefully push out the camera with your finger.
3. Remove the camera.

1. Put the new camera in the opening in the board and gently press it in.
2. Connect the camera’s contact to the motherboard.

• 1 × 3.4 mm Phillips

1. Take the logic board and plug in the connector at the bottom.
2. Now you slowly fold the logic board into the device.
3. Make sure you don't squeeze in any cables.
4. Bend all antennas and connectors to the side.
5. Press the logic board in to make it click into place.
6. Then fasten the single screw of the logic board.

• Connector
• Antenna plug

Now attach all the plugs.

1. You can position the antenna plugs with tweezers and then click them on.
2. Also attach the connectors for the display and the volume buttons.
3. All connectors engage with a click. If not, remove the connector and try again.

1. Now insert the SIM tray.

If it gets stuck, the logic board may not be sitting right.

• Connector

1. Insert the front camera and attach its connector.

• 5 × 4.0 mm Phillips

1. Then place the speaker back over the USB board, press it in and screw it tight.
2. Make sure it's latched in at the bottom.

• Battery connector

1. Connect the battery connector.

• 10 × 4.0 mm Phillips

1. Then attach the midframe with the NFC tag.
2. Latch it in and press it in all around.
3. Then fasten all the screws again.

• Fingerprint connector

1. Before you put the back cover back on the case, reconnect the fingerprint sensor.
2. Position the back cover over the device and lift it slightly so that you have access to the connector. Keep the back glass as still and close to the device as possible.
3. You can use a plastic tool, such as a spudger, to reach the connector and push it down. Alternatively, you can use a longer tool like ESD tweezers or the ESD spudger. Be patient and try to keep your hands as still as possible.
   
   

1. Before reattaching the back cover, check the glue. It should be sitting evenly on the back cover. You can remove any excess glue.
