what's happening? Do you have a purple logo and a black screen? If so are you using the standard a/v cable or a component cable? Perhaps you've got flashbios 3.0.3 on your backup chip which doesn't work with 1.6 boxes, only 1.0-1.5 and 1.6b xboxes. Also how come you need to get to the backup? Did you get a bad flash? So many questions, I know...
