The problem appeared after i erased my ipod touch completely again. And once again i faced with the problem... So i already knew what to do...
First of all i tried to jailbreak my ipod touch after completely erasing it. Once i saw "Replacing Kernel" loading i put my ipod touch into DFU mode.
Video tutorial how to boot ipod touch or iphone into DFU mode:
Once your iphone or whatever else in DFU mode, you cant do anything...
So just open iTunes and let it restore it for you.
Once it restored, you can jailbreak it again ( with red sn0w. or whatever else you like to do that with.. )
