[LG Optimus L9 P760, P765, P768, P769] aod990:
Hey all,

I was playing around with my LG and I'm stuck at Security Error problem...

I used fastboot from this thread and user ICS version although my android is JB... Flashed boot and recovery with these images.

Tried to flash stock rom with offline method but I can't make it right:
