today i tried to update the xbmc on my neigbours Xbox. All went well till the part that i noticed the "DUALBOOT.XBE" was the startup file. I renamed this to "Dualbootbak.xbe" and renamed the "Default.xbe" of XBMC to "Dualboot.xbe". After this the box only crashes with code 21.
Later i found out this was a software hack, not a mod chip. Could it be that this Dualboot.xbe was part of this bios?
i tried to boot from a disk but it will not take it. If i could only find a way to rename that file back i think it could work again.
If anybody has any idea what to do, please let me know.
