I tried to unlock OEM in developer option but it's greyed out. Can any one help me how to unlock bootloader of Nokia 6.1 plus officially
Nokia doesn't allow bootloader unlock on its phones officially. So, that's why it is greyed out. Moreover, you were never able to unlock the bootloader even when it was not yet greyed out.
I also want to know Why OEM unlock is disabled in Nokia 6.1plus after q update
