At last, apologize for my poor english
as reported in the official Sony page "If Bootloader unlock allowed says Yes, then you can continue with the next step (to unlock bootloader). If it says No, or if the status is missing, your device cannot be unlocked.".
It seems to be a problem of the carrier but if your carrier is Movistar you can give a look on this thread:
search on Google "Bootloader unlock allowed: No... SONY solve it, please!" (sorry but i can't post link)
