error 21 on boot up

[Quall999]

If your xbox lost the time, and your xbox dash was removed, then that is probably the reason. If you cannot boot any disks, a modchip will have to be installed in order to fix the problem. If you can, I suggest finding a replacement dash and doing a softmod exploit to get it onto your xbox.

btw, you cannot ask where to get a replacement. I stated that slayers might have it, but that is not for sure. The dashboard is MS's property and downloading it is like downloading a copy of windows. That is why asking for xbox apps such as this one is against the rules. We are less strict when people ask for home brew applications, but still will not offer a direct download do to their legality (compiled with illegal xdk).
