Samsung Galaxy A510F, replacement of USB PCB, jack and buttons

Insert the SIM card eject tool, a SIM eject bit or a straightened paper clip into the hole on the SIM tray at the left side of the phone.

• Press firmly to eject the tray.
• Remove the SIM card tray from the phone.
• Properly orient the cards in the tray when reinserting them.

Power off your phone completely before starting this procedure.

• Apply an iOpener to the back cover to loosen the adhesive.
• If needed, use a hair dryer or heat gun for extra assistance. Be cautious not to overheat the device:

• The AMOLED display and internal battery are vulnerable to heat damage.

Insert the tip of an opening pick between the frame and the back cover at the bottom near the USB-C port.

• If necessary, use a suction handle or strong tape to pull up the back cover.
• Slide the opening pick to the bottom right corner and secure it there.

Insert a second opening pick at the bottom right corner.

• Slide it diagonally across the screen to the bottom left corner, cutting the adhesive.
• Leave both opening picks in place to prevent resealing of the adhesive.

Insert a third opening pick under the bottom left corner of the back cover.

• If needed, apply more heat to soften the adhesive further.
• Follow iOpener instructions to avoid overheating.

Apply too much heat and you risk damaging your phone's internal components.

• Slide the opening pick along the left edge of the phone.
• Leave the opening pick in the top left corner to hold back resealing adhesive.

Insert a fourth opening pick under the top left corner of the back cover near the camera.

• Slide the tip of the opening pick along the top edge of the phone to the right corner, cutting the adhesive.
• Leave the opening pick in place in the top right corner to prevent resealing.

• Insert an additional opening pick under the top right corner of the back cover.
• Slide the tip of this pick along the right edge, working from top to bottom, to separate the remaining adhesive.

Remove the back cover.

• Apply strong, steady pressure to the phone with a stack of heavy books for at least several minutes.

Locate the display flex cable on the bottom of the phone, then use the flat end of a spudger to carefully pry it up and disconnect.

Prepare an iOpener and apply it to the display for at least two minutes.

• Apply heat as needed, reapplying the iOpener and reheating if the phone remains cold.
• Follow the iOpener instructions to avoid overheating.

Apply a suction cup to the upper edge of the phone when it's warm to the touch.

If the screen is cracked, use strong tape or superglue the suction cup in place and let it cure before proceeding — risk of adhesive failure.

• Insert an opening pick into the gap and slide it to the top right corner to start cutting the adhesive.

Slide another opening pick to the top left corner.

Do not remove the opening picks until repairs are complete, as this may cause the adhesive to seal over again.

Insert another opening pick near the left edge, sliding it along to break the adhesive.

• Leave one pick at the bottom left, holding its position to keep the adhesive open.

• Place a fourth opening pick at the bottom left corner.
• Slide the pick towards the bottom right corner and leave it in place.

Leave the opening pick to prevent adhesive resealing.

Insert a fifth opening pick near the top left corner, then slide it down the left edge to break up any remaining adhesive.

Apply heat to the screen with a iOpener.

Be aware of the rectangular adhesive strip underneath the screen.

Insert a plastic card into the gap between display and phone assembly on left edge.

• Press plastic card in and slide it back and forth to cut through entire adhesive.
• Verify adhesive is fully cut before proceeding.
• Remove four opening picks from corners once adhesive is cut.

Do not remove the screen yet, as display cable remains threaded through frame.

Thread the display cable carefully through the frame.

Disconnect the screen from its mounting points.

Locate and disconnect the antenna connector on the lower right side.

Disconnect the main board connector using a spudger from the rear side of the PCB.

Avoid damaging the flex part.

• Dislodge the microphone using the flat side of a spudger.
• Pry with care to prevent breakage.

Peel off the PCB from its compartment and lift it without pulling.

• Proceed element by element, being cautious not to break flex parts.

• Be careful not to damage or disconnect the two flex cables connected to the buttons at each end of the PCB (circled in red on the photo).

• Remove or elevate the opposing glass panel.

• Careful not to damage the underlying components.

  Peel away the two button connector strips.

The replacement board is shown as a whole. Note that the flex parts marked in yellow on the image are the most delicate components of the PCB.

Install the new USB board into its enclosure.

• Connect the board's plug to the corresponding socket on the main board.

Remove all sticker remnants from glued parts using a gentle adhesive remover.

• Filter out any remaining adhesive residue underneath the button assembly.
• Backlight elements: apply glue to the back and attach them securely into their casing.

Reconnect the antenna connector.

Reassemble the 17 screws at the rear of the phone.

• Secure the screen with its corresponding glue.
• Return the back cover to its original position and ensure it adheres properly.
