Ok here it go some screens:
Read Codes Screen: 
These code i got works perfectly on SIM1 .. to lock / unlock etc..
Direct Unlock Screen 
With these method i get my SIM1 unlocked but not the second one.
Anyway, as i told before, after that when i put a SIM card (of a different network) in the SIM2 slot it asks me to put the code (and the one i got with NCK doesn't work).
When i go to the engineermode -> SIMMeLock -> SIM2 -> Network Personalization i have the option to unlock it as well but, again, i need the code...
Here are the screens if u want to see:
