Default [Q] Wifi and Bluetooth doesnt working


I flashed new ROM on my Lenovo P780, its EU rom LiFe v0.7.
Everything is working fine and stable, but one thing isnt,

I cant turn on Wifi or Bluetooth.
When I try to turn it ON, the turning on animation appears, but it keeps coming back as OFF. So I just cant turn it on.

I was trying switch the ROM back to stock rom, but this Wifi error is still there.

Does anyone know what to do with this ?
Thanks a lot.
