First i useed you method from this:: Turning the "brick" into a smartphone

If you had unlocked bootloader and did OTA(Over the Air) update, then you probably ended up with a dead phone, aka brick. Don't worry, it is not completely bricked, still can be saved!

Download UnbrickingXperia2011.zip file from this post below.

Unpack the .zip file and place the .ftf file in Flashtool\firmwares folder.

Open Flashtool.

Get your phone to flashmode, make sure it is turned off, press down Volume DOWN button and connect USB cable.

In Flashtool, click the lightning button, pick Flashmode and choose the Xperia_2011_FreeXperia_ALL.ftf file.

Let Flashtool finish.

Install stock firmware and kernel to your phone.

Remove USB cable from your phone and start your phone.

Try not to brick it again, less problems for you.

Than i flashed whith flashtoll and this fw Xperia Active (ST17i)_4.0.2.A.0.42_CE.ftf

but i have still bricked phone ,any idea ??

my bootloader is not unlocked!!
