I have compiled and installed a custom kernel for my OnePlus 2 (following "Building-Nethunter" in the Wiki). This booted, and via the NetHunter App I could successfully download install the chroot environment. However when starting the Terminal Emulator App, I end up at "normal user" in / directory.
So the su/chroot call was not executed. Is there a batch script to do so? Where? I did not find any script named "kali". :-(
