[Nexus 7 Q&A, Help & Troubleshooting] iBolski:
I did a backup of my applications on my Nexus 7 (2012) running 4.3. I also backed up the data partition itself.

I then upgraded to the latest KitKat and when I attempt to restore the application backup (which is a tar file), it quits without restoring and doesn't give an error.

Here is what I attempt to do:

1. First, I ensured that the boot image was insecure, just to be safe, but either boot image doesn't work.

2. When I choose to restore the app data backup, I enter the name of the backup (which is a tar file).

3. I then acknowledge the prompts on my tablet to allow the restore. There is no password on the backup.

4. The toolkit then states it's restoring the backup. But then, within about 10 to 15 seconds, it goes back to the menu.

Here is a logcat I took of the restore attempt. Any ideas on why it's giving me the error message it does? It says it's not running with encryption so it aborts. I never encrypted the backup, so I have no idea why I'm getting this error message from the toolkit.

All the software is up-to-date.
