Step 1 — Power Off & Remove SIM Tray

First, switch off the phone completely and remove the SIM tray.
This step is important before opening the device.

---

Step 2 — Remove the Back Cover

To separate the back cover, we need to soften the adhesive.

You can use:

• A heating pad
• Or a heat gun/hairdryer

In this guide, we’re using a heating pad.
Place the phone back cover facing down, select Mobile Phone Heating, and let the cycle complete.

If you’re using a heat gun or hairdryer, warm the edges gently—do not overheat, as that can damage the cover or internal parts.

Once heated, place a suction cup near the bottom area to create a small gap.
Slide a plastic card pry tool into the gap and work your way around the edges to cut through the adhesive.
Take your time, be patient, and avoid pushing too deep to prevent damage.

When all sides are free, carefully lift the back cover and set it aside.

Step 3 — Remove the Mid-Frame

Make sure the SIM tray is out.

Next, remove the fifteen screws securing the mid-frame.

Disconnect the power button/fingerprint connector.

Then, use your pry tool to separate the mid-frame from the body.
Work gently around the clips until the frame is fully released.

---

Step 4 — Disconnect the Battery

Always disconnect the battery connector before touching internal components.

---

Step 5 — Remove the Charging Port Board

Now, disconnect:

• Both main flex cables
• The two antenna plugs

Then remove the screw securing the charging port board.
Lift the faulty board out of the frame.

---

Step 6 — Install the New Charging Port Board

Place the new board in position and fasten the screw.

Reconnect:

• Both antenna heads
• Both main flex connectors

Make sure each connection clicks in properly.

---

Step 7 — Reassemble the Phone

Reconnect the battery plug.

Place the mid-frame back and secure all 15 screws.
Double-check that all clips are locked in place.

Reconnect the fingerprint/power button connector.

Insert the SIM tray.

---

Step 8 — Install the Back Cover

Before placing the main back cover, make sure the adhesive is still good.
If needed, apply B7000 glue or use a new double-sided back cover adhesive.

Press the back cover firmly into position using bonding clips.
If you don’t have clips, rubber bands will also work—just apply even pressure.

Leave it for a while to let the adhesive bond properly.
