[Galaxy S7 Exynos] Bootloader locked

It was sim locked and a friend of mine unlocked it for me. I think the firmware was ROGERS because it had rogers apps. It was rooted, it had custom recovery (TWRP). I turned off OEM unlock and after a restart it was FRP locked: "Custom binary (recovery) blocked by FRP lock." it also says "dm-verify verification failed... Need to check the DRK...
