This is kind of alarming for anyone who wishes to root their device. Today AT&T issued a no prompt OTA update. When receiving the update the phone just receives the update and auto reboots the phone when finished. Everyone knows that if you want to root your device you want to stay away from ota updates since these almost always patch known root methods. If you are going along all happily rooted it would really stink for your phone to auto update, killing root on your device.
There is no changelog for the LG G4 update, but AT&T claims the update was to fix an issue with the address book? I'm not sure why something so seemingly insignificant would require an urgent and automatic update. Its funny that Jcase uploaded that video showing root progress earlier this morning just before the auto udpate.
