1. The back cover’s heavily 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.
2. 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.
3. 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. The iFlex makes it easier to get into the gap between the glass and the frame because it's made of very thin, stable metal. But it also makes it easier to scratch the frame of your S10e. To get into the gap initially, you can use the iFlex and then continue with the iPlastix as soon as possible.

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.

• 8 × 3,9 mm Phillips

1. Loosen the Phillips screws that secure the cover. The contactless charging coil and NFC antenna are attached to the plastic cover.
2. The cover is hooked into the top of the housing and the lower part is lightly glued on. Carefully slide a flat tool under the attached areas and loosen them.
3. Now you can remove the cover together with the coil.

• Battery Connector

1. Using the spudger, carefully disconnect the battery contact from the motherboard.

Always lever from a side where there are no small components on the motherboard. This avoids unintentional damage to capacitors or ICs.

• 7 × 3,9 mm Phillips

1. Loosen the Phillips screws that secure the speaker and then remove it.
2. You can loosen the speaker more easily by lifting it up a little at the openings at the side. The openings are marked with small triangular arrows.

• Connector

1. Disconnect the headphone jack connector from the motherboard. Carefully position the spudger and remove the connector.
2. Lever the side of the jack to release it and then remove it from the case.

• Camera Connector

1. Now disconnect the front camera connector using a spudger.
2. Pry it up from the free side where there are no PCB components.
3. Then take the camera out of its holder.

• 3 × 3,7 mm Phillips
• Display connector
• Fingerprint connector

1. Using the spudger, carefully disconnect the marked contacts from the motherboard.
2. Remove the several Phillips screws.

4. Now you can carefully remove the motherboard. Make sure it doesn’t get caught on the connectors you already disconnected.
5. Then set the board aside in a safe place.

• 3 × 3,7 mm Phillips
• Display connector
• Fingerprint connector

1. Take the motherboard and carefully place it into the device. Be careful not to pinch any cables. Bend all connectors to the side.
2. First place the board at the bottom and press the charging socket into its opening. Then press the board down until it is correctly positioned everywhere.
3. Insert the SIM card holder. If it's stuck, don't push it in with force. In this case check if the mainboard is correctly seated.
4. Then fasten the screws of the motherboard.
5. Finally reconnect all connectors.

Test especially all functions of the part you replaced.

If the adhesive on the back cover is still intact, you can seal your device without using a new adhesive frame.

1. Put the back cover back in its original position.
2. 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.
