Mobile dead after wrong software update through flash tool

Hi Team,

Last night after doing the fast boot my device has stopped working. The screen is not getting on, I tried to plug the charger but there's no notification light. I tried to remove the battery for few minutes and still no hope. I also tried to load fastboot once again by pressing Vol UP + Power / Vol Down + Power / Vol Up + Down + Power still no joy. The next step I did is I remove the battery then insert my phone to my Laptop then I plugged back the battery, it wasn't detected.

even i check the following thread http://en.miui.com/thread-100553-1-1.htm...

which needs a bit of technical skill....but there is no luck on that as well

I have read many threads on forums about MI Flashing, the problem is I can't load my device neither in fastboot nor detect my phone.

Request your help on the same from chip level to repair the hardware as u t the one in market to fixit this issue.
