Hi. I installed the semi-tethered jb, along with winterboard patch and other stuffs. My problem is that everytime I try to boot or reboot the ipod (slide to power off/bossprefs/reboot command in terminal), I get a solid black screen and the ipod is totally unresponsive. It won't boot into not-jb filesystem, in fact I don't even get to the infinite apple icon loop, nothing shows up on the screen no matter what I do. I am able to get it into DFU and boot into jailbroken fs via tether. Anyone know why this would happen?
