First my english ins't good so sorry if i don't make myself clear.

I have a S4 LTE International GT I9505 and i rooted it and installed a custom rom, but now i came back to official firmware.

So when click on wifi it simply doens't turn on and a notification appears:
" SECURITY NOTIFICATION - Your device's security blocked a non permitted action. It isn't necessary any action" with a grey shield icon.

If someone help me i will be grateful.

thx.

EDIT: It seems that i cant choose another unlock option too.

Rooting and installing a custom room tripped (set) a knox void status. This is knox messing with your phone.
Best approach is 1) keep root; 2) install SuperSU (from the market), disabling knox when asked for;
3) Now you can try this wifi-i9505-problems-flashing-custom-rom or this simple solution for wifi not going on. Good luck.

Do a factory reset and than uninstall all Knox applications!
