How can I undo a botched rooting? Android 5.1.1 I've got a Samsung S6 G920F with Android 5.1.1 which I've tried to root by using the Chainfire method through Odin. Sadly something went seriously wrong when I ran the rooting and my phone is now stuck displaying the Recovery is not Seandroid Enforcing message when I try to turn it on. I've tried just redoing the rooting but it doesn't help.

So what I basically want to do is to undo the whole thing, or get this rooting to work asap.

And also, this doesn't seem right:
Current Binary: Custom,
System Status: Official

The log from Odin:

Check if you can reboot to stock recovery (Switch off the device completely. Boot into recovery mode by pressing and holding Volume Up, Home and Power keys at the same time. Release all three buttons when device screen flickers and the main screen of Recovery mode appears), from there you can factory reset your device.
