And what do you do if you don't have the FOTA?? My phone didn't prompt to update, it updated on its own in my pocket. I tried to reboot out of TWRP recovery and it didn't let me. I didn't know my phone took the update so I wiped the phone and restored a backup of my root. I seen that thread afterwards and I don't see an option of it.
Before the update I rooted, downloaded xposed.
I have spent maybe 10+ hours looking for a solution with no luck. Oh, best part... had the phone for 5 days before it accepted the update (wish I knew LG just pushed the update :-/ )
