I bought and Xbox 360 Arcade a while back. It had been flashed to play backup game discs. I attached a 250 HDD a while later. I want to now install EvoX so that I can FTP my Xbox 360. I got EvolutionX Build 3935 and burnt it to disc from XISO image. When I insert the disc in the Xbox 360 it forwards an error saying that the game could not start and I should try downloading the game again. I don't believe it has a physical modchip so does EvolutionX disc require a physical modchip to boot/load? If not what would be my next step? Any help would be greatly appreciated.
