Default LG SOL stuck in Emergency Mode

Hello!

I have installed Cyanogenmod 9 on my LG Optimus Sol E730. In this moment, my phone won’t start. When I press the power button, the display shows „Emergency Mode!”. Before "Emergency Mode" screen appeared (when Cyanogenmod worked fine), I have tried to go into Recovery Mode, but I was getting the blue screen and the phone restarted. In this momment the phone doesn’t allow me to go into Recovery Mode. I have tried to reinstall the original firmware with KDZ Firmware Update, but I get an error and the program closes.

KDZ log -

How can I reinstall the software on this phone?
Can I use other software like KDZ?
Please help me with a tutorial or some information.
I mention that I have installed Windows 8 x64 on my pc.

Thank you, guys!
