Step 2. Remove the tray

Use the ejection tool (aka Needle) or Paperclip. Push the tip all the way into the hole until the tray ejects, and then pull the tray of SIM and Memory card (Micro SD) out.

⚠️️ Pay attention! The tool must be inserted into a hole on the edge of the phone's housing. Do not press too hard. It may break the tray eject mechanism.

Step 3. Open the back cover

We recommend using a special heating device such as a separator machine, heat gun, or heating mat. It will simplify the process. You can use a home hairdryer, but you will have to make a nozzle by hand or have a suitable one in the kit to gently heat and concentrate the heat flow in the right place.

ℹ️️ The surface of the back cover must be heated to soften the adhesive underneath. The approximate heating temperature is 50° C / 125° F.

Use a thin plastic film or pick for separation. To facilitate the process, you can use isopropyl alcohol. It is often most difficult to pass the tool between the parts to be divided. Choose the far edge from the FFC cables or buttons.

Do not use a lever or any force for separation that could damage the elements inside.

ℹ️️ Be careful! The back cover is glued not only around and along the edge but at some spots on the middle covers around the cameras, fingerprint sensor, contact pads.

Step 5. Open the middle cover

Pry around the edges. Move an opening tool along the edge detaching the clips and remove the middle cover with NFC, Wireless charging, loudspeaker and antenna pads and tracks. The middle cover protects the printed circuit board (PCB).

Try to lift the cover by the edges and don't push anything too far inside, so as not to accidentally break or short-circuit anything on the circuit boards.

⚠️️ It is highly recommended to disconnect the connector to avoid possible short circuits during disassembly.

Also, try not to use a metal tool to disconnect the rechargeable battery connector or do it carefully.

Step 11. Remove the motherboard

Carefully detach the motherboard. Lift the far side (where are the cameras) enough to disconnect the inter-board cable connector, which connects both circuit boards. It is located on the inner side.

Carefully remove the printed circuit board. There is no need to use a lever or try to reach the circuit board by force. Make sure that nothing is getting in the way or holding the circuit board.

⚠️️ Do not bend the circuit board when removing it or push tools under it. Unbeknownst to yourself, you can damage components or cables from the inside.
