Pervasive Kingroot app avoids uninstall I managed to root my Verizon Samsung Galaxy Note 10.1 tablet with Kingroot, but I'd like to remove it and switch to using SuperSU (because of KingRoot's aggressive practices and somewhat shady reputation). Even after uninstalling it and deleting everything labelled kingroot or superuser in /system, I still get Binary Occupied from the SuperSU app.

I believe there is a hidden process somewhere monitoring attempts to delete it and replacing the binary. For example, in system/usr there is a directory called iku (kinguser?) which replaces itself immediately after being deleted. Similarly, in system/xbin there is ku.sud and start_kusud.sh, which I can delete but instantly reappear.

This may be a quirk of the Samsung system, or some kind of hidden or inaccessible process. I've followed numerous online tutorials, and tried to run the Replace_Kingroot_With_SuperSU.zip method, but to no avail. Anybody know of a workaround?

Edit: here is part of the stdout form a script I ran. Note where it says operation not permitted:

rm failed for /system/xbin/ku.sud, Operation not permitted
rm failed for /data/data/com.kingroot.RushRoot, No such file or directory
rm failed for /data/data-lib/com.kingroot.RushRoot, No such file or directory
rm failed for /data/data/com.kingroot.kinguser, Directory not empty
rm failed for /data/data/com.kingroot.master, No such file or directory
rm failed for /system/bin/.usr/.ku, Operation not permitted
rm failed for /system/bin/rt.sh, No such file or directory
rm failed for /system/bin/ddexe, Operation not permitted
You did it wrong I guess. Despite all the tutorials you found online, I wonder how you missed the right one : There's a "safe" uninstall feature within Kingoroot app. This removes completely the app and the binaries from your device. 


Open the app
Click three dots upper right, find settings menu.
Click "Remove Root".


Your device will be rebooted and root should be removed.
