I am using redsn0w with the 6.0 firmware manually chosen. when i try to jailbreak, it gives me one of three outcomes. It either says I'm missing Keys.plist for the firmware, the exploit failed, waiting for the reboot that never happens, or jailbreaks it tethered and then when i boot it again, it tells me I'm missing Keys again. I last jailbroke at 5.1.1 so I have no idea of which programs I should be using now. I just wiped everything off my iPod so I am determined to jailbreak it now. When it waits for the reboot the screen turns on but it's blank and it just stays that way.
