Hello everyone, here is my situation. I upgraded my iPod from 5.0.1 to 5.1 to un-jailbreak it so the warranty would be restored. So, afterwards I wanted to downgrade back to 5.0.1. I saved my SHSH blobs and made I signed firmware in iFaith. At first iTunes gave me error 1604 and said "iPod not detected". That was all fixed after I put my iPod into PWNED DFU mode. Then I successfully downgraded in itunes to 5.0.1. When I was downgrading my iPod had the ifaith wing logo and the loader bar. So, now my ipod touch is stuck on a totally black screen in PWNED DFU mode. iTunes and my computer still recognize it. iTunes says it is in restore mode. I tried using iReb to no avail. The ipod is a fourth generation 32 gb model. Help would be great guys, since I use my iPod everyday for music and facebook
