Thanks, I'll try!
Then, I found a quite annoying "bug" in this Rom: if inside privacy guard I set an app to ask if being started in "autorun", (not core apps, stuff like google search or gallery) after boot and keyguard the dialogue appears (accept-deny) but is not clickable and after that the entire system goes totally stuck...
I had to force reboot a lot of times and uncheck one to one privacy guard settings for all apps in the few seconds before appear it's dialogue to rescue my system...
