Ok, so here's the deal:
I've got a shadow file and a passwd file.
So i unshadowed it, like: # unshadow passwd shadow > final,
but when i try to crack the final file i get the following error:

$ john mbfinal 

No password hashes loaded

But i can see that there are hashes in the file. What am i doing wrong?

Where is mbfinal in your code redirected? You only defined final. Nonetheless it's best you try this method:

/usr/bin/unshadow /etc/passwd /etc/shadow > /tmp/final.db
john /tmp/final.db

Do you get any output?

I did that, but the problem is that the hash is a sha512, and the normal jtr (installed without any patch) does not support this ecnryption, and that's why it didn't load any hash.

Yeah, it'd be a fruitless and long journey to brute force a SHA-512 hash without a wordlist, that's why it's not supported.
