Hey, sorry if this is in the wrong place. I accidentally updated my ipod touch 3g to firmware 4.2.1. I am trying to jailbreak again using RedSn0w. When i get past the part on Redsn0w where you put your ipod touch into DFU mode it gets stuck on exploiting with limera1n. Ive searched around and many people are having the same problem. Ive tryed running Redsn0w as administrator and it still has not fixed the problem. What can i do to fix this? Help would really be appreciated Cheers.
