I have a elite from last xmas and within the last few months more and more of my games had started to show up as "open tray" error.

What seemed odd was tht it had only occured after i had to update my 360 when i went on LIVE. But they say that the updates can't do that.

So yesterday i decided to take mine apart since it's out of warrenty. I took it apart and used canned air to clean the inside. I also took apart the dvd rom and cleaned it out good and any plugs within the 360 i unplugged and plugged back in.

After i put it back togetyher , it now plays all my games fine.

Guess it was just dirty inside and not the update.

If yor out of warrenty you should try it, maybe you will be lucky lke me and find out it was just dirty.
