I did a Hard reset and it worked for me on error code 0x80a30204. For a Hard reset hold power button on console down for 10 seconds then power it back on.

i dont think Microsoft will help they just say Look Up the Forums

Hard reset the xbox by holding the power button until it completely turns off or unplug it from the power source for 30 seconds. Then turn it on this way. Push and hold the bind and eject buttons. While those buttons are being held, push the power button
to turn it on. Keep holding the bind and eject buttons. The xbox will chime twice, release the bind and eject buttons. You will be at the trouble shoot menu. Pick reset xbox. Here you can choose "keep games and apps" or "keep nothing". This will reset your
xbox to factory defaults with or without your games and apps based on your selection. I was struck with a corrupted system file from my preview alpha skip a head dashboard. I had to do this.
