Can I Update downloaded OTA Lolipop update without rooting

[justzarakkhan]

I have Samsung galaxy Grand Prime with OS Android 4.4 KitKat. It has recieved 5.1 update in many countries, But here they have no plan to send the OTA update, Now I have downloaded the lolipop update zip file from website youmobile.

will I be able to update my phone Using
the Stock Recovery (update from external storage ) option? Or do I have to use Flashify App?
