I thought about using KingoRoot, but it doesn't support 5.1 and up. I'm not sure if the one click root programs unlock the bootloader. I would only unlock the bootloader because I want to install CyanogenMod to replace stock Android. The Nexus Root Toolkit might work. But I've heard recently that people have been having trouble with it and I don't want to brick my tablet. Any help is appreciated. Thanks!
