2. Disassembly: Carefully open the phone casing using the provided tools. Disconnect the battery and other relevant flex cables.
3. Remove Old Screen: Gently detach the old, damaged screen assembly. Be mindful of any adhesive or connectors.
4. Pre-Installation Test: Before fully installing the new screen, connect the new LCD assembly's flex cable to the phone's motherboard. Do NOT remove any protective films or labels at this stage. Power on the phone and test the display, touch functionality, and color accuracy. Ensure there are no dead pixels, lines, or unresponsive areas.

Operating (Post-Installation)

Once the screen is successfully installed, your device should function as normal. The new screen offers high color saturation, resolution, and a smooth touch experience. Apply the included tempered film for additional protection.

Maintenance

To ensure the longevity and optimal performance of your new screen:

• Avoid dropping the device or subjecting it to strong impacts.
• Clean the screen regularly with a soft, lint-free cloth. Avoid harsh chemicals.
• Keep the device away from extreme temperatures and moisture.
• Consider using a protective case in addition to the tempered film.

Troubleshooting

If you encounter issues after installation, refer to the following common problems and solutions:

• Black Screen: If the screen remains black after powering on, press and hold the power key and volume key simultaneously. If the phone vibrates, it indicates that the main flex cable might not be properly installed. Power off the device and carefully re-install the screen assembly, ensuring all connections are secure.
• Incorrect Screen Response/Unresponsive Touch: This could be due to an improperly seated flex cable or a faulty connection. Power off the device, disconnect, and reconnect the screen's flex cable. Ensure no dust or debris is obstructing the connector.
• Display Issues (Pixel Distortion, Lines, Wrong Colors): Verify that the LCD cable is not bent more than 90 degrees. Recheck all connections. If the issue persists after re-seating the cable, the screen itself might be defective.
• Screen Not Fitting Properly: Ensure you have the correct model screen for your device (M2101K7BG, M2101K7BI, M2101K7BNY, M2101K7BL). Double-check that no debris is preventing the screen from seating flush in the frame.

If troubleshooting steps do not resolve the issue, contact customer support or seek professional repair.
