PLEASE READ THIS: Before reading this, make sure the problem is your xbox and not the disc simply by putting a different disc into your xbox 360.
If your like me, you obviously have and xbox 360 that has or has had the "open tray error". This error is when you have a disc in your xbox 360 and it doesn't "see" it and it displays the message "open tray" as if there isn't a disc in your xbox. There is also an error just like this but when you put a disc in the xbox makes two clicks. I call this error the "double click error".
Anyway, in this instructable I will teach you six simple ways to fix these error that I have tried, and every one of them has worked for me at least once.
Not all of these will work at one time, and then work at another. So try them all, at least one of them will work. But if your in a hurry try Fix 5 (Step 5) for the open tray error and fix 6 (step 6) for the double click error because they have worked the best for me the most times.
Sorry about the pictures, they wouldn't really help so I didn't take them. But any way, let's get started
Step 1: Fix 1: Blow some air into the disc drive
What you'll want to do is open up your disc drive, (where the disc goes) and blow some air into the space that let's you see into the xbox itself. I think this sometimes works because dust or something gets on the laser that reads the disc, and by blowing some air into the space, you remove that dust.
