Shield Recall - disabled tablets

The old tablet is supposed to self disable once the new one is activated.
Do we know how nvidia is going about this in order to prevent it?
I assume going full CM would prevent this, but is there a way to prevent that without fully replacing the rom ?

Best Method to Backup Data from No Root Recall Tablet ( Locked Bootloader) to new one

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.

Shield Recall: Wait time to receive tablet?

Hello! I've done some looking around on the forums before making this, but I might have missed it since I'm looking rather specifically. I'm wondering what peoples wait times are to receive their replacement tablets? I submitted my info for the recall on August 7th, and received the confirmation, but here it is 4 weeks later and I have yet to receive any further information or my replacement tablet. I'm wondering if I should keep waiting, or if there's something I should do? I tried contacting the recall hot-line, but every time I do, they seem to be closed.
