I guess the availability of custom kernels for this device is, well, limited. You don't need to install magisk or other root methods if you don't need them explicitly.Thank you, I had no issues installing this and followed the install instructions in the first post.
Its been like six years since I've done this before and was wondering if I now need to install anything else like a kernel or SuperSU / Magisk? I've come straight from the Z2 stock rom and unlocked the bootloader then installed LineageOS & openGapps. I'm sure that I'm only halfway there.
