HELP!!!Xperia u Bricked!!! topic

Hey guys im in a lot of trouble right now. I have bricked my device and im not sure if i will be able to restore it back. Im not worried about the data in the device anymore,i just want my device booting back into any OS possible!!

Here's what happened,i was flashing the stock firmware of the device through flashtool.The process was about half done.All of a sudden my device fell down from my computer desk.The cable got disconnected and the device doesn't boot anymore.Any solutions to make it boot back up? Please help...
