Samsung Galaxy Nexus (Verizon LTE) Micro USB Charge Port & Main Mic Replacement

Step 1 | Micro USB Charge Port & Main Mic

Charging issues may indicate a faulty micro USB connector board.

Acquire replacement micro USB board and visit the specified link for procurement.
Required tools include an opening tool and a small Phillips screwdriver.

The original micro USB connector board was revision LF-A G 1145, while the replacement is LF-A G 1150 23-3.

Step 2

Remove the battery and SIM card.
After removal, take out the six screws from the back.

Step 3

Remove the back panel using a plastic opening tool.
Pry carefully around the edge of the screen to avoid damage.

Step 4

Remove the screw at the bottom of the device.

Use an opening tool to disconnect the ribbon cable.
Remove the antenna, speaker, and vibrator assembly from the bottom.

Step 5

Never force the clip — risk of damage or breakage.

For CDMA phones, rotate the assembly counter-clockwise to release the clip.
For Google GSM phones, gently push the clip away from the assembly to unclip it.

Step 6

Remove the following components from the main circuit board:

Ribbon cables
Micro USB board, also containing the front notification LED and microphone
Screen connector
Note: On some phones, the volume rocker may be soldered to the mainboard (not CDMA); detach it if possible.

Careful when handling the power button - held in place by glue only; separate it from the case without detaching it from the circuit board.

Antenna, gently detached using a plastic opening tool

Step 7

Remove the main circuit board carefully.

The main circuit board is held down by ribbon cable connectors which can be easily popped off or removed with an opening tool once lifted.
Be aware that these must be reconnected when putting everything back together.

Bend the ribbon cables carefully to avoid damage, especially near the power button and earphone connections.

The main circuit board is connected to other components using more ribbon cables which should not be removed.
The camera ribbon cables must stay attached but handle with care to prevent dust from getting inside.

Step 8

Remove the micro USB board using a prying tool or fingers, as needed.

Ensure all remaining adhesive is removed from the surface.

Step 9

Remove the broken USB board.

Peel off the adhesive backing from the new USB board.
Install the new board, taking care to align pins with guides.
