Repeated Update Failures and Misreadings

Question

After the most recent update (2.01 bundle 358), owner deleted Zinio manually from the tablet. Destop Software reads the playbook as having OS 0.0 bundle 0, while table says it has 2.01 bundle 358. Steps tried:
1. Install update. Result: update failed.
2. Download Zinio from App World, install update. Result: update failed.
3. Restart playbook, install update, update complete, unplug playbook, hit okay, playbook restarted, replug playbook into computer. Result: OS reads as 0.0 bundle 0.
4. Restart playbook, restart computer. Result: OS reads as 0.0 bundle 0.
Side effects: Desktop software doesn't allow anything but OS updates and backups, computer cannot read blackberry device as being plugged in (i.e. cannot see it in Computer folder), as a result cannot transfer files from computer to playbook. System tray on computer recognizes when playbook is plugged in. Desktop software still recognizes device, but reads OS wrong.
Suggestions?

Hopefully you have copies of pic, videos and documents.
Try the following it is to debrick the playbook. I seriously hope this will help you.
First I would like you to do a Back Up of your PlayBook using your computer and BlackBerry Desktop Software.
This can be downloaded for free from http://us.blackberry.com/apps-software/desktop/
After the Back Up is complete I need you to unplug your PlayBook and then push and hold down the Power Button until the unit Force Powers Off.
Now, while Desktop Software is still open on your computer and the PlayBook Powered Off, Connect the PlayBook to your computer.
You should see and error screen from Desktop Software pop up that has the options to Retry, Update, or Cancel.
QUICKLY choose the Update option.
This will erase all the information off of your PlayBook and Re-Write the Software back onto it. Once it's complete your PlayBook will need to go back through the setup wizard, and you can then perform a restore using Desktop Software to return your information. The only thing that won't come back after the restore are the apps that you downloaded from App World but they can be easily Re-Installed using the My World feature in App World.
