I am not responsible if anything goes wrong.
Post any questions here: [Q&A][ROOT] Root for SHIELD Tablet 2.0 (Lollipop)


Pre-requisites:
  • Already flashed OTA 2.0 (Unless bootloader is locked in which case read instructions for locked bootloader.)
  • Unlocked bootloader and flashed CWM from here
  • SuperSu zip file from here
  • PC with working adb and fastboot

Instructions (Unlocked bootloader):
  1. Reboot tablet into recovery mode
    Code:
    adb reboot recovery
  2. Flash SuperSu zip file with CWM
  3. Reboot tablet
    If CWM asks to fix root, say yes.
  4. Profit.

Optional Reinstall CWM (The OTA removes it)
  1. Flash via fastboot
    Code:
    fastboot flash recovery recovery.img
    May need to flash a couple of times to get it to stick.
  2. Reboot tablet

Instructions (Locked bootloader):
  1. Download update but DO NOT UPDATE YET
  2. Gain root on previous build via towel root.
  3. Flash CWM from link in prereqs via Flashify
  4. In CWM choose update from zip and choose the zip file in the bottom of your 'nvidia' folder on your internal storage (/sdcard/). DO NOT REBOOT
  5. Flash SuperSu zip file with CWM
  6. Reboot tablet
    Don't reboot if you want to reinstall CWM below
  7. Profit.

Optional Reinstall CWM
  1. Copy CWM to root of internal storage
    Code:
    adb push recovery.img /sdcard/
  2. Flash via adb shell
    Code:
    adb shell 
    mount /data
    dd if=/data/media/0/recovery.img of=/dev/block/platform/sdhci-tegra.3/by-name/SOS
    If the mount commands errors with device or resource busy just skip it and move on.
  3. Reboot tablet

Thanks for the guide. Hopefully this is just me being stupid, but I ran into some issues following the guide. I rooted via TowelRoot, and then downloaded the OTA without flashing it. After using Flashify to install the CWM image, and installing the OTA via CWM, I'm unable to boot into the recovery image anymore. I can't boot into it through the hardware key combo, and I can't boot into it through ADB.

I'm following the locked bootloader steps, if it helps.

Edit: Nevermind, unlocked the Bootloader is by far the easiest option.

What is happening instead of it booting?

it boots to the old "android on it's back with the red triangle icon" screen. It appears that installing the OTA overwrites the recovery image.

What about if we had already updated to L, but had never unlocked the bootloader? I was rooted before with towel root, but never actually unlocked boot. Does the unlocking method still work? Or am I SOL for now?

Yes the unlocking method still works. It is not an exploit it is officially "supported" by Nvidia. See here

As mentioned below unlocking will wipe all data.

I don't think it should be any different. They didn't encrypt it or anything. Unlocking should be possible with just doing an oem unlock. Of course this will wipe your data, so be sure to do a backup.
