Finally it worked. Don't know if one needs the files from the mediafire link or not but I think one needs to delete all the files less the Directories folder and passphrase.bin. Thank you =)
EDIT: checked the SHA-256 of the files from the previous BCAT that I downlaoded and the medifire one and they are the same so I guess deleting those files + setting the clock with switch-time (thing that I did previously) did the trick
EDIT2:
@Chrushev thank you for the answer, didn't see it before making this comment.
