Root ATT Marshmellow Update - USB Debugging Greyed Out

[mistermsk]

Hi All,

Just received the Marshmellow update last night. However, USB debugging is now greyed out. i tried plugging my phone into my computer (which has the LG G3 driver installed) however, I still can not turn LG G3 debugging on.

Are you rooted and took the update?
The reason I ask, is you posted in the root forum.

Problem is, I am trying to root and no longer can since there is no way to enter USB debugging mode. So, right forum.

Ok. Found out it was McAfee doing it. Took me awhile to figure out how to turn McAfees off.
