My phone was working fine until this morning when I tried to start wifitether and got the message "no SU binary installed" Does this mean I lost root somehow and have to root it again?

Its possible that you removed root permissions solely for wifitether by accident. Uninstall and reinstall then when it fires up make sure you select allow when superuser popup comes on. If you know your way around you can avoid the uninstall by simply going into superuser app and fixing permissions for wifi tether. If not then you'll need to boot into recovery and reflash supersu as you did during the original root process.
hope this helps!

Ok thats your first problem. you should NOT be using SuperSU app, its not compatible with the SU binaries we have installed on this phone. Until further notice this app is NOT compatible and wont be supported. Do to the binaries we used during the root process you must use the "superuser" app from the market. Some people have hacked in different binaries but unless it is specified that SuperSU is compatible then always is superuser.:angel:

Also if you have difficulties removing it then you may have to use tibu to freeze then uninstall SuperSU. If that doesnt work your only option will be ADB, it may just uninstall fine it may not it depends. But you need to get rid of it.

I was having issues like this. I had to swap between supersu and superuser. But it just never worked right. Once I flashed a new Rom it worked just fine.

Given the phone is S-On the only real way to ensure a permanent, functional root on stock would be to first remove the SuperSU binary and app. It has been confirmed that SuperSU does not work.

This can be done directly from TWRP's file manager or ADB with the unsecured kernel:

The binary can be found at: /system/xbin/su
And the app can be found at: /system/app/superuser.apk

BOTH FILES must be removed. Freezing SuperSU will not work

Next download and then flash the following zip in TWRP or CWM:
Superuser Binary+App

At this point you should have fully functional root on stock

Again, simply flashing Superuser over SuperSU will not work, the app and binary must be removed before flashing.

Your methods will remove the ability to provide root permissions to any apps...?

You need the binaries and the app to get root perm on anything from within the rom. I don't recommend this.

The zip contains both the superuser app and corresponding su binary.

I overlooked the zip portion of your comment. I thought that you were saying to simply remove the app and the binary and reboot. However the binaries wont load from SuperSU in the first place so you should eb good to just get rid of SuperSU and install superuser. If everyone has been following the recommended rooting steps that is. But if that were the case noone would be installing SuperSU

I'm having the same issue-- in TWRP file manager I see only system/bin. If I try to delete the files with adb it complains about a read-only filesystem.

I know this is an old thread but if it helps others, I had the same issue with TWRP, there is an option in SuperSu to unistall and switch to a another superuser app. Put the superuser zip above on the phones memory card, then just install regular superuser from the market. Now go into SuperSu and pick the option to switch to another app, once done go into file explorer and delete the files stated above if they are there. Now reboot into recovery & flash the new superuser zip..
