Phone [Q] Xperia Z totally Dead, No response, Not getting Connected to PC.

HI, i am New member but i have been reading threads but never posted anything.
So my Problem is that I was on Miui ROm for Xperia and it had many Issues like Camera and Headphone Jack.
i was on TWRP recovery with Unlocked Bootloader and i have a Nandroid backup on Ext SDcard of Working Rom.
So i wanted to get rid of the bugs so thought of installing a new Miui ROm from any other developer and found out this thread

http://forum.xda-developers.com/show....php?t=2306162

i downloaded and installed it with Aroma installer and it got installed Correctly But after restarting My phone is totally Unresponsive. (LED notification Light is Spoilt earlier) No vibrations on Power+Vol up or Down.

while installing and downloading this ROm i did not knew it was for Xperia S and not for Xperia Z and that was the Stupidest thing i did.

now 'Flashtool by binary' is also not detecting My phone and FLashtool by Sony is also not detecting my Phone. So what can i Do to get my Phone to working even on Stock Rom?

please Help... Have only One Phone.

Thank You.
