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 the SIM card out.
â ī¸ 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 display module
â ī¸ Pay attention! Disassembly has a maximum 3rd difficulty because the process begins with the disassembly of the display module. If you have no experience or are not sure of your skills, we strongly recommend that you contact a specialized service center.
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.
âšī¸ī¸ The surface of the display module 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.
The process can be seen in our video entirely so as well as in detail, at the end of the instructions.
Step 7. Open the middle cover
Separate the middle cover from the housing. Be careful. The fingerprint sensor is located on the housing and connected with a motherboard via cable, but its connector on the motherboard is pressed/secured with an extended metal cover. So, to get close to the fingerprint sensor connector, we need to remove the metal cover and disconnect the battery connector.
Step 8. Unscrew the screws
Using a screwdriver Torx T4), unscrew 4 long screws.
âšī¸ī¸ Be sure to note the location of the screws before disassembling. When assembling the device, screwing the screw in the wrong place may damage the device or its part. To avoid damage, the removed screws and individual pieces (as gaskets or brackets) must be laid out in the appropriate order, or the screws and their holes in the phone must be marked with colored markers.
Step 11. Disconnect the battery connector
Disconnect the battery connector as soon as possible.
âšī¸ī¸ The Google Pixel 4a (5G) G025N model has a battery G025E-B with 3885 mAh capacity (aka rechargeable battery).
â ī¸ 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 12. Disconnect the connector
Disconnect the fingerprint sensor connector and remove the housing.
Step 13. Unscrew the screws
Using a screwdriver (Torx T4), unscrew two long screws securing the loudspeaker assembly.
Step 14. Remove the loudspeaker
Disconnect the coaxial cable connector and remove the loudspeaker and a small board with antennas.
Step 16. Disconnect the connectors
Pry up the connectors of the headphone jack socket, cable to the small board. Also, the charging port is connected with the motherboard from the inside, so be careful.
Step 17. Remove the motherboard
Carefully remove the printed circuit board. There is no need to use a lever or try to reach the board by force. Make sure that nothing is getting in the way or holding the board.
â ī¸ 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.
Step 19. Remove the charging port
Using a screwdriver (Torx T4), unscrew one screw and remove the charging port.
Step 20. In the display frame remained
âšī¸ī¸ In the display frame remained: the earpiece speaker, battery, headphone jack socket, vibration motor.
