Dead
I've had my 360 since the summer 2006 and never had one rrod problem. I plug in the kinect and all is well. Come back to it later that same evening (mid dec) and get rrod. Hmm...that's strange. Give it a reboot and all is well.
Come back to it tonight (havent used it since) and the damn thing is rroding almost every time as soon as i power it on. If I keep trying i eventually get it on and all seems well, but there is defiantly something wrong since the kinect update. Wouldn't have thought it was a physical problem like it was with overheating as it happens immediately when powered on from cold and if i keep powering it off and on it eventually works.
Fess up microsoft and sort out whatever dodgy update you've rolled out.
