[Xperia Z1 Android Development] techemically:
C6916 recovery failed 14.2.C.0.159 rooted w/ SuperSU

Root appears successful and root apps get su access (Titanium installs and functions among others); however su binaries won't install. Tried every t-shooting method there is. Was hoping to get TWRP to flash SuperSU .zip installer to fix this issue. Have re-flashed Different stock firmwares (14.4.B.0.56 - no rooting method I can find since the kernels i need to downgrade dont exist any where i can download them from)) and reflashed this current (14.2.C.0.159) one and began the whole rooting process over again always with the same result. Does the "pwn" root method from jcase and beaups actually work or does it just appear to?
