I have been trying to jailbreak my 2nd Gen iPod Touch with firmware 3.1.2 multiple times now and it just won't work. I get the screen with the USB cable and the Itunes logo and then it goes black and doesn't reboot. EDIT: I've tried restoring, manually putting it into DFU mode, moving the blackra1n file... I don't know what else to do. Pwnage Tool says that your iPod must be jailbroken before using it and since blackra1n isn't working it seems like I'm out of options unless someone has a fix for me. EDIT 2: The model number starts with MB.
