Root LG G3 verizon vs985 5.0.1 24b

I've googled the heck out of this. I have tried ioroot.apk, towlroot.apk, kingroot.apk. I have ran many adb scripts including Newest root method V03, LG root script 2014 v1.2, many others. I have pushed busybox to /data/local/tmp and superuser. No root. however, with all the said I have root checker pro. 1. Superuser apk is installed. 2.Superuser binary is installed, well somewhat. 3. Root user account errror. 4. no root shell user. 5. busybox is not installed. I do also have newest TWRP and it is fully working. SU binary will not update normal or in TWRP. I have tried to manually in stalled the su UPDATE zip, didnt work. i have tried to uninstall SU with full unroot so i can try to reintall it, it will not uninstall no matter what i do.
