Is this when the Xbox boots? error 21 can mean something is wrong with the dashboard.

How was the Xbox modded? if it was a modchip some will let you FTP to the console even if it won't boot the dashboard, so you can fix the problem easily.

If its a softmod it will depend. If you can still boot from the DVD you can use something like HeXEn to repair the dashboard.

Either way more information would be of help so people can try help you, especially on how you modded the Xbox and what you did before you got error 21.
