I have my phone ( exynos SM-G965F DS) for ~ 5 months with system uptime sometimes more than three weeks and OEM unlock option never appeared on Oreo . Booting into download mode shows RMM state = prenormal. After flashing pie update OEM unlock appeared on first boot and I enabled it, after wiping the system, booting into download mode shows RMM state prenormal and OEM lock off.
I waited for 7 days and still the same. I tried flashing complete stock Oreo ( BRJ6) and waited again with no success. I tried flashing the combination file and I could get OEM unlock option to appear in developer settings but no effect on RMM state ( still prenormal). I need to root my phone and RMM lock keeps me from doing so, any suggestions would be appreciated
