Alright, so I created a modded ISO disc for Red Dead Redemption and I have been trying to install it for hours. I do not have a flashed Xbox, so I hotswap my disc when the download starts at 1%. Usually the disc starts slowing down right when the download hits 48%. I made sure the system cache was cleared, and I even cleaned my disc and the laser. I'm not sure if I need to download a whole different ISO or just burn another disc. I am using an Xbox 360 Slim if that gives anyone an idea of why it's not working.
