i had the same problem i was trying to fix my friends xbox and the message was a 16 error message but it was on a non-modded xbox so i wanted to know how to fix it if i needed a new hard drive or what do i need to do to fix it
u don´t need a new hdd.Just reset the clock.If this doesn´t work re-install the M$dash.M$dash=Microsoft Dash,Original Dash.Good luck
