i9506 WiFi problem while porting rom topic

Hi to everyone (especially to devs),
I was porting lollipop from N9005( with note 4 stuff) to i9506, but I have some problems with the wifi.
I tried to replace the wifi drivers from /vendor/firmware and /etc/wifi but still IT WON'T OPEN!!!!
Everything else is working ok :o

Any idea?

Thanks
