I tried doing an update to 100MT and during the update it froze before it finished and continues to do so.  I got into the service menu and force loaded the cd/dvd and it went to 100%, the application program said NG and we tried force loading it and it would get stuck at 88%, tried this several times and always gets stuck at 88%.  Any ideas of whats wrong, because right now i cant do anything with my system it just keeps saying insert appropriate disc.  any help is appreciated
