I flashed boot.img from KitKat from zip,
When I tried to install KitKat ROM from recovery, I got this message:


  this package is for "ST18i,ST18a,urushi" devices; this is a "haida"
The reason for the error is, you have downloaded the wrong package. The downloaded package is not compatible for ray.
