As the title states I am in need of assistance. I am trying to flash my first xbox, and so i dont have any other devices besides my xbox hooked directly into a spare sata port on my mobo. All the guides I have read have told me to download dseo13b.exe and run in test mode so it can install the portio64.sys. However when i try and run DSEO and enable test mode, it freezes on the progress bar and stops responding. In fact that is what happens no matter what option i choose on that program, bar the exit and how-to-use option. So i found a way to get my pc into test mode using the cmd. However the problem of the portio64.sys not installing still persists. I have read around that i have to sign the actual portio64 driver, however when i try to use dseo13b.exe to do this, it freezes when I try to sign the driver. So im basically stuck at this point in the process and i cant seem to get this portio64 to install. So any help would be very appreciated.
