Safety Information and Precautions

Performing repairs on electronic devices requires careful handling. Please observe the following precautions to prevent damage to your device or injury.

• Always operate in a dust-free environment, away from direct sunlight, to prevent dust particles from entering the device.
• Wear anti-static gloves when handling the flex cable and other internal components due to their extreme sensitivity to static electricity.
• Apply force at a 45° angle from the bottom when using pry tools to separate components, minimizing the risk of damage.
• If adhesive needs to be preheated for easier separation, use a hot air gun for no more than 3 seconds and ensure the temperature does not exceed 80°C (176°F). Excessive heat can damage internal components.
• If you are not confident in your ability to perform this repair, it is strongly advised to contact a local professional repair shop for assistance.
• Disconnect the device's battery before starting any repair to prevent short circuits.

Installation Guide

Follow these steps carefully to replace the charging port flex cable. Refer to the safety information before proceeding.

1. Power Off Device: Completely power off your Samsung Galaxy S24 Ultra.
2. Remove SIM Tray: Use a SIM ejector tool to remove the SIM card tray.
3. Heat and Open Back Cover: Carefully apply heat to the edges of the back cover using a hot air gun (max 3 seconds, ≤80°C/176°F) to soften the adhesive. Use the suction cup to create a gap and then insert the ultra-thin triangle pry tools to gently separate the back cover from the frame. Work slowly around the perimeter.
4. Disconnect Battery: Once the back cover is removed, locate the battery connector and carefully disconnect it using a nylon spudger to prevent accidental power-on during the repair.
5. Locate and Remove Old Flex Cable: Identify the existing charging port flex cable. It is typically located at the bottom of the phone. Carefully disconnect any ribbon cables or connectors attached to it. Use the anti-static screwdrivers to remove any screws securing the old flex cable.
6. Install New Flex Cable: Position the new Yondista charging port flex cable in place. Ensure all connectors align correctly. Secure it with the screws previously removed. Reconnect any ribbon cables.
7. Reconnect Battery: Reconnect the battery connector.
8. Reattach Back Cover: Carefully align the back cover and press it firmly back onto the frame. Apply gentle pressure around the edges to ensure the adhesive seals properly.
9. Test Functionality: Power on your device and test the charging functionality, data transfer, and microphone to ensure the replacement was successful.
