Asus Zenfone 9 USB-C Charging Port Replacement

Power off the phone.

• Open the SIM card tray using a removal tool or a paper clip.
• Remove the SIM card from the phone.

Be cautious when applying heat to avoid damage to internal components.

• Use an iOpener or heat gun to soften the adhesive around the back cover's edges.
• Insert an opening pick or guitar pick into the gap and gently pry along the edge.

If initial attempts fail, try using a thinner pick or a sharp instrument, starting from the bottom edge to minimize damage risk.

Remove the nine highlighted screws using a 000 Phillips bit.

• Careful when removing the screw highlighted in yellow, as its decal can be easily damaged.

• Remove the decal on top of it with a sharp instrument.
• Pop off the plastic cover using a spudger, opening pick, or guitar pick.
• Start near the battery to avoid damaging flat cables or camera modules.

Remove the six screws marked with a highlighter using a 000 Philips bit.

Careful handling is required as one of the screws has a protective sticker.

Do not force the sticker — it can be easily removed with a sharp instrument.

• Pry out the speaker using your finger, an opening pick, or guitar pick.

Use a spudger, opening pick, or guitar pick to gently pry out the circuit board.

Do not bend or fold any cables if they are still connected; this will cause damage.

• The circuit board also contains the SIM card reader.
• It is not necessary to disconnect the two flat cables from the main board.

Use a spudger to disconnect the old USB-C connector from the main board.

Careful: This requires some force, so go slowly.

• Pull back firmly on the "KB" side of the flat cable to release the adhesive holding it in place.
• The USB-C port will come loose and can be removed from the phone case along with the flat cable.

Remove the blue plastic covering from the new cable's adhesive.

• Align the cable with its 'KB' marked side facing down, towards the phone's bottom.
• The new port should fit where the old one was removed.

• The red gasket will create a tight seal upon insertion.

• The cable is keyed to the gray plastic peg seen in the second photo.
• Ensure the new port's screw holes align perfectly with the circuit board.
• Press the cable down over the peg, securing it with adhesive.
• Reconnect the 'MB' side of the cable to its corresponding port on the main board.
