Hi 1701-e
It's possible that an update from 5.18 to 5.18 has been pushed through to fix home screen issues. I didn't see that update message on my 360, however I thought I'd test it by perfoming a factory reset using the 'Keep recordings' option.
When the box rebooted it did indeed display the message saying 'software has been updated'
I then checked under Settings > Info > About and checked the info showing there against what was there previously (I keep a copy of any 'About' changes in a wordpad file for comparison) however nothing had changed there and it showed the exactly the same info as previously. (June 18th was when the last update was performed on my box)
