Ensure the red wire on the ribbon cable aligns with Pin 1 (the dot) on the chip.

This is where the "disagreement" usually pops up. If it fails here after a successful erase, the issue is likely electrical noise or a weak USB port. 💡 Quick Pro-Tips Ensure the red wire on the ribbon cable

When your programmer throws this error, it's usually due to hardware instability rather than a "broken" chip.

To help you get this sorted, could you tell me: What is the exact model number printed on your chip? Are you using a SOIC8 clip or did you desolder the chip?
