Security Error?

Hi guys,i was trying to flash this rom ,but then something went wrong with my phone and it boots into LG Security Error screen
I can't get it to S/W update ,i can get it into LG recovery but when the lg support tool can flash it over 4%,it's stuck there
i think it has something to do with my bootloader being locked and i tried to flash a unlocked-bootloader-required Rom

I got the same problem and I can't seem to find any solution.
I tried to root it with no success on the newest version of Kitkat so I tried to flash an older version of it and I got stuck in a boot loop.
while trying to flash another firmware i lost access to flashmode and Sony pc companion does't detect the phone anymore, fastboot does however work and my bootloader is locked.
also charging doess not seem to work for me anymore.
Seems like we got almost the same problem, does anyone got any solution to this?
Would be mostly appreciated!
Also the firmware I tried flashing was D6503_23.0.1.A.0.167_RU.
