Use the SIM card ejection tool to remove the SIM card tray. Insert the tool into the small hole next to the tray, and gently press until the tray pops out. Set the tray aside in a safe place.

Use a heat gun or hairdryer to gently heat the edges of the screen. This will soften the adhesive holding the screen in place. Move the heat source in circular motions around the edges for about 2-3 minutes.

Attach a suction handle to the lower part of the screen. Gently pull up on the handle while using a plastic opening tool to separate the screen from the frame. Start from the bottom and work your way around the edges. Be patient and avoid using excessive force.

Once the screen is lifted, use a spudger to carefully disconnect the screen's ribbon cable from the motherboard. This is typically located near the top of the device. Handle the cable gently to avoid damage.

Take your replacement screen and connect its ribbon cable to the motherboard. Ensure the connection is secure. Align the screen with the frame and press down gently to adhere it to the device. If necessary, use double-sided adhesive tape or pre-cut adhesive to secure it properly.

Carefully align and press the screen back into place. Ensure there are no gaps around the edges. Reinsert the SIM card tray into its slot.

Press and hold the power button to turn on the device. Test the new screen by tapping and swiping to ensure touch functionality is working properly. Ensure the display is clear and responsive.

Inspect the device for any loose components and ensure the screen is firmly in place. If everything looks good, you've successfully completed the screen replacement.
