Seriously, this console update is a mess. I rather have a working console compared to a console that can not play anything what so ever. It doesn't take long to figure out your update has done something to people's consoles.
Heck you just go to look at Major Nelson's Blog post on the update. Nearly every single comment is posting issues. Varying from the console no longer reading discs, to the console no longer allowing you to install games to the Hard drive after update and generally unstable consoles that can't connect to XBL parties, can't play apps...
I just find it annoying that you refuse to even make a statement or give us any solutions or insight. All you have to say is, "Oh sorry, it messed up some consoles, we'll release a fix soon."
But no, support is like: Clear system cache, oh that don't work? Send it in for repair. I seriously feel sorry for those who have bad consoles due to this update and have to pay for a repair because it's warrenty is out of date.
