As it says in the subject line, I'd never felt compelled to root my Shield Tablet buy now wishing I had. It is on the latest 5.1.1 update and I want to transfer my data in such a way as go clone it onto the new tablet I've received due to the recall.

Is there anyway of making a Nandroid backup and loading recovery without unlocking and losing the data I want to keep or another alternative method such as the built in adb backup solution.

Thanks for the assistance in advance.

I managed to use Helium (Carbon)
But remember having several issues:
First step was getting the desktop app to recognize the tablet in debug mode. In the end drivers need to be reinstalled with 'have disk'.
Think i used the ones from nvidia website

Also afterwards Helium had trouble detecting existing backups. Had to install all apps manually on the new tablet, 'fake' backup everything again, then replace all .ab files with the ones from your 'real' backups. Some details here.
