Have a Xbox v1.6 with Xenium Ice v2.2.1 from 2005. In 2007 it overheated and the vert hold went and was told it couldnt be fixed, so I let it sit. Then a few days ago, I started it back up in hopes to fix it for my youngest son now of age. We got it to work but everything was in Black and White. I noticed it was inadvertently set to PAL mode in the Xenium menu so I switched it to NTSC and then the color came back.
Here is where I think I went wrong.
Then again on the Xenium menu, I clicked "Reboot".
Now when I start the xbox from the power button it goes to the blue dashboard, but there is nothing to pick and it says "Testing123" at the bottom and can only push A which does nothing or B which reboots it and ends up right back on this page. I know there are many dashboards loaded on the hard drive, but don't know which the default is.
Note that I have no CD.
What do I do
