I just installed a SmartXX chip in my V1.0 XBOX. I couldn't find a clear tutorial so here's what I did: I flashed the chip with the software that I downloaded from SmartXX, the 3345. I flashed the chip with X2.5032 bios (I don't think this was right) Then I ran Slayers Evox Auto Installer V2.5. Xbox still won't recognize the back up I have. I keep getting disc unknown. Any help would be appreciated.
