I have an iPod touch 2g that is currentand stuck in a recovery mode loop. I don't know what OS it had before the loop and I don't have any of the SHSH blobs. I have read that the fix requires me to use redsn0w but I need to know what os was originally on it. I recently acquired this ipod on craiglist so the original ipsw is not on my computer. So how would I break the loop?
