Common Reason for Oppo A37f Not Connecting with Unlock Tool

Sometimes users face issues with their Oppo A37f when trying to connect to Unlock Tool. One of the main reasons this happens is due to driver issues.

Another reason can be the faulty USB cable or port. Ensure the cable is not damaged and that you're using a working USB port on your computer. Sometimes the phone's EDL mode isn’t activated properly, so double-check if you’ve followed the instructions to enter EDL mode.

2. Change USB Port or Cable: Try a different USB cable or connect to another USB port on your computer.

3. Reboot and Retry: Sometimes a simple reboot of the phone and the computer can fix connection issues.
