- Remove Back Cover: Carefully use the prying tools to open the device's back cover.
- Disconnect Battery: Locate and disconnect the battery connector from the motherboard to prevent short circuits.

- Final Installation: If the screen functions correctly during testing, disconnect the battery again. Apply new adhesive around the phone frame. Carefully align and press the new screen into place. Reconnect the battery, reassemble the back cover, and secure all screws.

Maintenance
To ensure the longevity and optimal performance of your new screen, follow these maintenance guidelines:
- Cleaning: Use a soft, lint-free microfiber cloth to gently wipe the screen. Avoid abrasive materials or harsh chemical cleaners.
- Protection: Consider using a screen protector and a protective case to guard against scratches, impacts, and accidental drops.
- Temperature: Avoid exposing your device to extreme temperatures, direct sunlight, or high humidity, as these can affect screen performance and lifespan.
- Liquid Exposure: Keep the device away from liquids. Even if your phone has some water resistance, a replaced screen might compromise its original sealing.
Troubleshooting
If you encounter issues after installing the new screen, refer to the following common problems and solutions:
- Screen Remains Black or Blue:
- Ensure all flex cables (display and touch) are securely and correctly connected to the motherboard.
- Verify that the battery connector is properly seated.
- Perform a hard reset of the device (refer to your phone's original manual for instructions).
- Touchscreen Not Responding or Inconsistent:
- This can sometimes occur with non-original screens. Ensure thorough pre-installation testing was performed.
- Check for any debris or damage on the flex cable connections. Re-seat the flex cables.
- Restart the device multiple times. Intermittent issues might resolve after several reboots.
- If the issue persists, the screen itself might be defective. Contact customer support.
- Display Issues (Dead Pixels, Lines, Discoloration):
- If these issues were present during pre-installation testing, the screen is likely defective.
