This is what the secondary error code for the Xbox 360 looks like for anyone wondering if you can tell the difference between the flashing lights for the code versus the normal flashing lights. To find the secondary error codes do the following:
1. Turn the 360 on and wait until the red lights are flashing.
2. Press and hold the sync button on the front of the 360. You need to hold it down the whole time.
3. Press the eject button for the first number.
4. Press the eject button for the second number.
5. Press the eject button for the third number.
6. Press the eject button for the fourth number.
7. Finally, press the eject button again to return to the red rings. You can release the sync button now.
To determine the 4 digit code number, look at how many red lights flash for steps 3-6 above.
1 red light = 1
2 red lights = 2
3 red lights = 3
4 red lights = 0
In my case, the secondary error code is...0102.
