Default [Q] HELP: Black screen after Carbon ROM flash

hi, I just flashed this ROM on my xperia s :
[ROM][UB][Linaro][KitKat][4.4.2]Carbon Rom[Unofficial][BUG FIXES BETA #3][PIE]

http://forum.xda-developers.com/show....php?t=2617846

After flashing, it just shows a black screen... nothing else! when I press the power button, there is a vibrate and that is it. nothing shows on the screen. then I realised that my bootloader might not be unlocked. does it affect it? how can I rescue my hp now??? please help..... urgent as I need my hp badly

thanks in advance to any kind souls out there....

my hp was on the stock .96 ROM rooted with CWM.
