Step-by-Step Google Pixel 4a Charging Port Flex Replacement

Step 1: Prepare the Phone and Tools

Start by gathering the required repair tools and the replacement charging port flex.

Having everything ready before opening the Google Pixel 4a will make the repair easier to manage and help keep the removed components organized.

---

Step 2: Heat and Remove the LCD Screen

The first major step is removing the LCD screen from the front of the phone.

Important: Heat the screen gently around its edges until the adhesive becomes soft. Avoid applying excessive heat.

For this repair, place the phone with the front screen side on a heating pad. Select the mobile phone heating option and allow the heating cycle to complete. Alternatively, a heat gun or hairdryer can be used.

Once the adhesive has softened, use a suction cup to lift the screen slightly. Insert a plastic card pry tool or something similar around the edges and carefully cut through the adhesive.

Work gradually around the screen rather than forcing it away from the body.

---

Step 3: Disconnect and Remove the LCD Screen

Gradually lift the LCD screen to approximately a 90-degree angle from the top and keep it steady.

The LCD connector bracket is secured with two screws. Undo these two screws and remove the bracket.

Next, disconnect the LCD connector to free the screen from the phone body.

Set the display aside safely while continuing with the internal disassembly.

---

Step 4: Eject the SIM Tray

Before removing the mid-frame, eject the SIM tray from the Google Pixel 4a.

Keep the tray in a safe place so it can be reinstalled during reassembly.

---

Step 5: Remove the Mid-Frame Screws

Undo the eight screws securing the mid-frame plate.

Keep the screws organized for use during the reassembly process.

---

Step 6: Separate the Mid-Frame from the Housing

Use a plastic card pry tool or triangle picker between the back housing and the mid-frame plate.

Run the tool through the gap to release the clips connecting the two sections.

Important: Be gentle around the flex cables while separating the back cover housing. Avoid pulling or putting unnecessary pressure on the cables.

Once the clips have been released, place the back cover on a suitable surface and carefully position the mid-frame body on the housing.

Do not force the phone or cables during this process.

Verify that the charging port is functioning correctly along with the basic operation of the device.

---

Step 25: Prepare the LCD Adhesive

Before installing the LCD screen, check whether there is enough adhesive remaining around the screen.

If the existing adhesive is insufficient, use B7000 glue or new double-sided LCD adhesive.

---

Step 26: Reinstall and Secure the LCD Screen

Heat softens the adhesive around the screen edges, allowing the display to be separated more easily from the phone body.

4. Why should I disconnect the battery during the repair?

The procedure disconnects the battery before continuing with the internal component removal and logic board work.

5. When should I test the phone?

The repair procedure calls for testing after reconnecting the LCD and before permanently securing the screen with adhesive.

6. What can I use if the original LCD adhesive is not sufficient?

The procedure specifies B7000 glue or new double-sided LCD adhesive for securing the display.

Troubleshooting

1. The LCD is difficult to remove. What should I check?

Make sure the adhesive has been heated sufficiently to soften it. Work gradually with the suction cup and plastic card pry tool instead of forcing the display.

2. The mid-frame will not separate from the housing.

Check that the mid-frame screws have been removed. Then carefully work a plastic card pry tool or triangle picker between the housing and mid-frame to release the clips.

3. The replacement charging port flex does not work after installation.

Review the charging port flex installation and the logic board reassembly. Make sure the replacement flex is correctly positioned and the board has been properly reinstalled.

4. The LCD does not work during testing.

Check the LCD connector and connector bracket. Make sure the LCD plug is correctly connected and the bracket is secured with its two screws.

5. The screen does not stay attached after reassembly.

Check whether enough adhesive remains around the screen. If necessary, use B7000 glue or new double-sided LCD adhesive, then use bonding clips or rubber bands to hold the display in place while the adhesive sets.
