Xbox 360 console not playing any dvd

[goodness]

please I flashed my Xbox 360 liteon then change the DVD drive and then I updated it. But after I updated it I can't play any game on it. Either original or downloaded. Only movies can play on it what should I do

That’s because you probably didn’t change the dvd key on the dvd drive to match your console’s dvd key

I second what sinasinahm said.

If you still got the other drive, extract the drive key, flash that to the other drive.
If you don't have the drive, the only option is to RGH the unit, boot into Xell, and grab your DVD key from that.

When you got your drive:
