I'll soon be getting a replacement for my Shield Tablet due to the recall.
I used a rooting method that used ADB and Fastboot to unlock the bootloader, flash CWM, then flash SuperSU and root.
It worked with Android 5.0.1, shield update 2.2, but the new tablet will most likely be on update 3.1, Android 5.1.
So I ask - will the rooting method and all of the files linked to in the guide (which I will link to down below) work with the new setup?
