LG G3 security error message, please help.

I've already navigated through some threads but my situation is quite different. So i decided to root my lg g3 as my test device. I already own a galaxy s6 plus so my previous device is perfect for development. I have the lg g3 from Verizon wireless running on Android lollipop. I followed a thread here of how to root this variant specifically. I installed the specific drivers and the root itself. It was very easy and i was 100% rooted. However, after i installed the teamwin recovery with no problems at all. Phone was working fine until i made a full os backup before installing cyanogenmod. The problem is that right after i made my backup, i rebooted my phone and now its stuck in the lg security error. I know some people have the same problem, however, most of them got stuck on bootloader. My g3 was perfectly fine only until made my os backup. Any thoughts on what i might have done wrong? Thanks
