Glad it is back up and working for you.

What was actually happening is you did use the same update method. The "new" update method only will work when you are on revision 10077 already, and into the future. This time though, the usb system didn't do something funny on the windows side the calculator wasn't expecting and so it finished properly.

The new method doesn't require administrator mode to run and basically pushed the files directly to the device first, validates them, and then on reboot performs the update. Unfortunately, there was no way to start using that until you are >10000 - kind of a chicken/egg thing.
