What steps should I take if 3uTools Error 1002 persists after trying common fixes?

If 3uTools Error 1002 persists after common fixes, consider trying the process on a different computer, as the issue might be PC-specific (e.g., driver conflicts, deeper software issues). You could also try using iTunes to restore your device (if it can detect it), as iTunes uses a similar but often more robust process. If all software solutions fail, there's a possibility of a hardware issue with your iOS device or its USB port.
