xperia sp bricked after hard reset

Hi.
I have Xperia Sp c5303 with C5303_12.1.A.1.207 soft or something like that, I cant turn on it to check.
One day i use reset button under the back cover to reset my phone when it jam.
After that phone doesnt work.
When i want power on, I can see only on the screen logo SONY and after that grey big settings logo in triangle and blue loading bar below.
Icon like here in this link, not my source https://cdn-images.xda-developers.co...4218538860.jpg
I wait few hours for power on, and nothing. So I try to install new soft.
I use flashtool and it stop every time on command " INFO - Reading device information"
I try 3 version od flashtool, every usb port in my laptop, 2 soft version, with antivir off, after computer restart and nothing happen.

I try even repair phone by Pc sony campanion (support) and it stop on step when I must turn on phone in flash mode. It shows that telephone is connected but never goes to the next point..

Can someone help me ? I have no idea what to do next.
