[Q] SuperSU on Galaxy S4

[rdorsch]

Hello,

I installed UPDATE-SuperSU-v1.65.zip with the TWRP recovery image on my Galaxy S4.
The installation completed successfully. But when booting into Android it does not start.
Logcat shows the attached entries. Did I do something wrong?

Many thanks,
Rainer

/system/app/Superuser.apk is there

I forgot to mention, that Superuser.apk

shell@android:/ $ ls -l /system/app/Superuser.apk
-rw-r--r-- root root 1966976 1970-01-24 21:18 Superuser.apk
shell@android:/ $

is available.
