Followed the guide for flashing Q on Galaxy S9 SM-G960F, flashed Devbase rom, restored all aps and settings, last app I installed is Family link for children and all working without problem till the moment when I try to restart with built in restart button in the quick panel (this is the second time in last 12 hours) , after that the screen goes black and I have the message in top left corner "Custom binary blocked by FRP lock". First time I reinstalled original firmware with Odin, redo all the Twrp stuff and reflashed Devbase but this time I have a full Twrp backup and I try to restore it after reflash with Odin. Anyone know the reason why phone got FRP lock and how to prevent it?
