Ok. I got the all in one package again and verified that debugging is still enabled and still get the same errors. Verified everything multiple times and still a no go. Also tried going back to V4 using the LG update tool and following the procedures to the letter to flash the v4 stock cab file. After flashing the v4 again and then trying to root using thd all in one package definitely getting the same error. Tried this multiple times and the only thing that I can figure is if you take the ota or go to V6 and then go back to V4 flashing the cab file, and try to root again, you will loose root permenetly. So to be clear. Was on v4, took the ota to v6, lost root, tried all in one package, verified settings, still get errors, flashed v4 cab back to stock, tried rooting with all in one again and got same errors, verified debugging, correct drivers, proper procedures followed, got the all in one package again, and still a no go. No disrespect intended as I'm a software developer too and verified every proper procedure was followed to the letter. It seems once going to v6 and then going backwards, you lose ability to root.
