🛠️ Still Not Working? Troubleshooting Tips

• Use Original Cables: This specific chipset is older. It is very sensitive to "charge-only" cables. Use the original Samsung cable or a high-quality data transfer cable.
• Try a USB 2.0 Port: Modern computers often have USB 3.0/3.1 ports (Blue inside). Older Exynos chips sometimes fail to handshake with USB 3.0 controllers. Try plugging the cable into a USB 2.0 port (Black inside).
• Enable USB Debugging: If you are trying to use ADB or rooting tools, ensure Developer Options are unlocked and USB Debugging is checked on the phone.
