Could you please be more specific. What do you mean by "still unable to crack any Scrypt"?
- does hashcat accept/load your scrypt hash correctly without a warning
- does it run without errors
- does it end with  Status...........: Exhausted

just saying that it is "unable to crack" doesn't really help to troubleshoot the problem. you must be much more specific.
As far as I understood the problem is/was that you used a different format ($7$...) to run the hashes, which hashcat does not accept. Maybe this was just a misunderstanding and you threw that format-conversion problem in front of the real problem you have, i.e. that scrypt cracking does not work at all for you. To avoid confusion in the future always try the example hashes ( first (and avoid mixing it up with other problems).

There could be many reasons why it doesn't crack for you.

You could for instance try to use a different version of hashcat (do you even use the latest release version from ?). You could try the beta version from
We also need to understand the real problem. Which you didn't explain at all, but my guess is that you have a problem with false negatives (status exhausted even if it should crack).
It could also have to do with your command line. Maybe you are using hashcat incorrectly, e.g. wrong command line arguments provided (but as far as I understood it works for you with other hash types).

Right, hashcat works fine with any other hash. (I guess I didn't realize that my question was vague)

For Scrypt:
It loads hashes fine without any errors/warnings.
It ends with Exhausted recovering 0/N hashes.
I give it a file with hashes and a dictionary where the correct results are listed plus some other random words.

The problem: It doesn't crack even when it should crack (just like you said)
