Ok, I have a V1.0 Xbox, and I'm ltools UDE1. I tried it a few once, didn't work, needed a update.xbe file, but it wouldn't fit on my memory card with the rest of the ltools files. I was getting a service error with the Xbox when it started up, and I couldn't get into the dashboard. That was fine, MA was able to still boot up, I gave it a shot with the UDE2, restored my C:. I thought I'd work but unfortinately the new dashboard "evox" didn't install. ok...that was cool, everything still worked normally, so I attempted UDE1 on more time, thinking maybe I messed up somewhere. No go, so I decided to make the update.xbe file fit on the memory card, which it eventually did. But now, nothing will load from my Xbox and I have that god forsaken service error again. So basically I can't do anything with my Xbox. Any ideas how to get rid of the error? Thanks.
EDIT: btw its Service Error 21
