while changing boot animation my galaxy grand quattro stopped working

I have rooted my phone as I watched a video in YouTube and as per that instructions I changed my bootanimation
I went to root directory there system-media there I changed original bootanimation to new boot animation.zip
Now the phone is not working only its showing the menu which we will use while installing zip file(power button+ volume up + main button)
Please suggest me to get back my grand quattro
