I'm trying to find a guide or some steps to putting Magisk on my SM-P600 but haven't seen anyone mention Magisk on it. My tablet is 5.1.1 with TWRP and SuperSU.
I'm not sure if it works with stock ROM, but it works fine on resurrection remix 7.1 rom. Just flash the latest magisk zip in TWRP, preferably without supersu though but I think they might work together.
