Would it be possible to provide a stock ROM for restoring our tablets if we were foolish enough to not do a full backup, or is that against the nVidia TOS? I wanted to try this until L was out, but now I can't restore (my developer application to nVidia is pending).
You don't need an account to download the factory image from nvidia. The one for L should be available in the next few days or so along with the aosp source.
