Default Verizon LG G2 Bricked Plz help!!!

I've used the lg flash tool to go back to stock several times in the past never really had any major issues. Today something went very wrong.

After the flash the phone boots on its own. I saw the lg logo, and then android with the blue bar under him. Then instead of seeing the verizon logo come up i get all black screen and it says:

Insecure boot.ing
cause=

This is up in the left hand top corner of the screen. There is no cause its just blank.

At this point the phone justs repeats those same 3 steps above over and over until i hold the power button to turn it off.

Next problem is i can't get it to stay in download mode again to repeat the process. The phone enters download mode for a slit second and flashes a bunch of white writing up in the top left hand corner of the phone so fast i cant read it and then the screen goes black.

Anyone seen any of this before?
I'm lost at this point...
