[Q] Sony D2303 stuck in bootloop,no recovery system,bootloader locked.

Hello xda!
This is my first post here, and I am sorry that it is a one of me asking for Your Help.

When I first got the phone with 18.0.C.1.13 jelly bean it was a dream. I mean fast,responsive with a intuitive UI and with a low price tag.
However i made some OTA updates to kitkat and the phone became a fraction of what it once was. I now realize that I should have probably made a dalvik cache clean-up but i think i may have messed up the stock recovery with CWM and Twrp.

Long story short I got fed up with 18.3.1.C.1.17 CE and had found this thread
http://forum.xda-developers.com/show....php?t=2762296
and downloaded XPERIA M2 D2303 Central Europe 18.0.C.1.13

Unfortunately RootLord links were broken so i downloaded from this user
http://forum.xda-developers.com/show...1&postcount=82

And then when i tried to flash the ftf for the first time everything unchecked.
On boot I got a boot loop
It starts with Xperia logo than some plasma waves resonating and then back to xperia logo and all over again.

I use flash tool 0.9.19.7.
Also i have noticed that in flash mode green light is only for a half a second while fast boot mode always stays blue.
I tried booting into stock recovery but I think i dont have one on my phone because a month ago i was experimenting with King root 4.1 and Cwm, Twrp.

I also downloaded SDK package installed Google drivers,flashtool drivers driver pack 1.5 from this forum
Also when I type adb devices into cmd or adb fastboot recovery nothing shows.

Please I am asking for your help because I dont know what to do, I have been trying to resolve this problem for three days.

Sorry for my English it is not my native tongue. :)
