Xperia SP C5303 4.3 not powering up

Dear Friends

 

Resently I unlocked my Xperis SO(C5303) bootloader. I Flashed Android 4.1.2 (12.0.A.1.257), After that it works fine.

 

I wanted to update this to official Jelly bean 4.3. I downloaded the file from below link and from many other source of downloads

 

http://xperiafirmware.com/8-firmware/37-sony-xperia-sp-c5303

 

After flashing 4.3 kernal mobile does not turn ON. SONY symbol come with three colour lights blinking and it goes off, this keeps repeating but never turns ON. To make my mobile work again I must flash 4.1.2.

 

I tried to check update service with Emma software. It always says no available service found...!!!

Kindly help...!
