LG STYLO (Virgin) secure booting error and root process

I root my phone (LG stylo ls770 virgin 6.0).

worked fine all day. Then when i shut it down. Now it boots up with:-

Secure Booting error
Error code 1003
MODIFIED!!

I have tried factory reset in recovery mode, but luck

I am at a loss of what i can do to fix the issue.

If any one can provide some suggestions that would be greatly received.

Thanks
