Yes but they don't. People who know what they're talking about call the OG Xbox "RRoD" a "
FRAG" error or "
Christmas Lights". Nobody has ever called the FRAG/Christmas Lights error a "RRoD" error. And people that do are always very quickly corrected as you were.
5 minutes of research could have shown you this. Instead you chose to argue with someone who very clearly knows more than you about the subject.
