Error code 7 typically means that it ran out of space while trying to apply the update.

To know for sure, you need to open up an adb shell and do:

adb shell df /system

repeatedly while its applying the update and see if the free space goes down to or really close to zero.

[Dave Hylands [:dhylands]]

I should note, that once it fails, it removes all of the backup files that it created, so the free space will suddenly jump to a bunch of Mb after it fails (this is why you need to do it repeatedly while the update is being applied)

If it's an out of space issue, then it's the same problem already covered in bug 907444. Oh well, I guess that confirms we still have the same problem.
