Default Lg-f180s bricked no IMEI no cameras working

Hello
Can anybody help
I had working phone but ive replaced screen it worked
But i realized i had to re align front camera
But after turning phone on both cameras doesnt work and no signal either ..
even when i remove sim there is no logo in notify area sim removed only no bars grey out and red cross on top ...
And when i slide status down on bottom says service disabled...
