I have been trying to root my S22 but continually run into the problem of OEM Unlocking. Everyone says just about the first thing to do is to select OEM Unlocking on the Developers Options but it isn't there. I even following one set of directions to try to make it show up but it didn't work either. I can't seem to get to the rooting without the OEM Unlocking. Anyone have any ideas? It doesn't have to do when I purchased the device which is what one person suggested but didn't help.
