I can't Turn On my Xperia Ray after failed update attempt

[Troublequestion]

Hello,

I just want to know what could I do on my xperia ray. It was August 7, 2014 when I was update my OS to ICS but the problem is my internet connection. While the process is being started my internet connection is cut. after that I can't turn on my phone. I tried to put it back the usb to my phone and then to my laptop it  has a Green light, that light in the lower part of my xperia ray but I can't turn it on..

please, I need your help..

Unlock Bootloader is sometimes needed if you wish to root your phone giving full access to all the hidden files which are pretty much the operating system of your phone or by unlocking your bootloader you will be able to flash custom roms, a rom been firmware
