[SuperSU] Bexton:
Just in case it helps you debugging

Here some logcat lines from the first boot after flashing the modified boot.img and clean installing 2.14:

W/PackageManager( 779): Not granting permission android.permission.REBOOT to package eu.chainfire.supersu (protectionLevel=18 flags=0x83e05)

I/ActivityManager( 779): Killing 2950:eu.chainfire.supersu/u0a57 (adj 15): empty #17

adb shell, su, do root stuff works. Titanium gives the following error in the Supersu logs:

error: only position independent executables (PIE) are supported.

Flashify says "Your (boot|recovery) partition couldn't be found. You won't be able to flash (boot|recovery) images. " and the corresponding logcat lines are:
