I'm always so nervous about installing custom WADs because of banner bricks so I decided to install preloader. But when I go to install it I get the "failed to get root, current IOS (36) has the bug fixed fakesign" error. I have cIOS36 rev 9 installed and read that if I downgrade it, I can install preloader, then upgrade back to rev 9. I figured I'd read about the ios downgrader, but everything I find is about downgrading the firmware with it. Do I have to downgrade the entire firmware to get the previous version of ios 36, or can I downgrade the single ios? If it matters, I'm currently sitting on v4.0U.
