Prompt porting help :/

so i ported a liquid smooth rom (4.4.2) from the galaxy ace 2 to my xperia u using this tutorial and novathor 4.4.2 as base ROM .. the rom sucessfully installed but it continues to play the boot animation forever and does not boot into the OS ..

i tried taking a logcat but it gives me an empty txt file :/
any idea as to why this happens and how i could fix this ?

thanks
