LarryD:
I used my other arduino uno as ISP and I successfully uploaded something via arduino uno to my clone nano.
I don't know if this over-wrote your bootloader, if it did you can burn the bootloader then try the manual method suggested.
Perhaps others can suggest a fix.
I have tried before, I guess I won't be able to solve this problem. I will keep using my uno as ISP. We better to be careful about what we buy. That nano was 5 dollars
