Will a factory reset unroot Android?



  • If I do a factory reset on a rooted Samsung/Android phone will it remove the root? Factory reset will return the phone to its out-of-the-box state, right?



  • If your rooting process made changes to system partition (SuperSU used to do that) or to the boot image (Magisk does that) then those changes would persist after a factory reset. However, superuser manager apps such as Magisk reside in data partition so these superuser manager apps would get deleted during factory reset.

    These superuser manager apps are responsible et al. for authorizing processes and apps to gain superuser (root) privileges. So after a factory reset you might end up in a situation that you do have a binary named su accessible but you still cannot gain root access because the corresponding superuser manager app to which it is tied to is missing.

    Over and all, your device would remain rooted even after a factory reset but the functionality of gaining root access might get botched due to missing superuser manager app. If your intention is to completely unroot your device or revert to a Google-certified Android OS status, then this path of doing a factory reset alone is incorrect to pursue.
