You must mount system as read write. Use other explorer. I use FX File Explorer (to me is one of the best).Hello I am in Android 12. I have rooted the phone following the instructions.
But when using a root epxlorer it says that SYSTEM partition is mounted as RW but I cannot delete anything.
Also when using adway it cannot write "hosts" in SYSTEM.
The Magisk promp showed up and I selected "Grant" as always.
And the magisk app it shows normal as usually when a phone is rooted. Why cannot do anything in "SYSTEM"?
