KT 5.1.0 - brick after USB bundle install

Hello everyone,

Today I made a brick from my KT 5.1.0 :(

All began when I decided to do its jailbreak. I used probably most easiest way i.e. by web page jailbreak-kt.tk. Although it was easy, I had to screw it up. :(

I don't know why but after first or second restart when I was in diag mode I chose option "Exit, Reboot or Disable Diags" and then I decided to choose "USB bundle install" (please don't ask me why because I don't even know myself). From this time I have still the same image on my screen.

Image may be NSFW.
Clik here to view.

I have tried to do hard resets and go through with the guide from this page (http://www.mediafire.com/view/?d4mqgzr4cbrttzu) but I get stuck on the 4th page in 8th point. I can't see Kindle-Fastboot in my device manager.

I don't know it's normal or not but I see the same image on my screen all the time (doesn't matter I reset, plug or unplug KT. It's still frozen as above, no touch response).

Could you give me a little piece of advice how to bring my Kindle to life?

Thank you in advance.
