Default [help] No bootanimation and no screen [xperia go] [rooted]

Well, yesterday i was trying to change bootanimation. Because it was not working, i changed and changed the desc.txt until this:

320 480 15
p 30 0 part0
p 0 0 part1
After that, it didnt worked.
It just showed that SONY screen and then the screen didnt show a picture. Even when i force restarted(taking sim card out and putting it in) it many times it still didn't show any picture.
If you want the then tell me.

Is there any way to recover the bootanimation?
