Hi all I'm new here. I have an iPhone 3G which is Jailbroken (iOS 4.1). I tried to update it but it didn't work, and now it's stuck and it can't recover it says error 1015. I downloaded redsn0w and I did download the iOS 4.1 IPSW, but when I try to open it, redsn0w doesn't sensor it, there is just ''back'' available. Step by step help would be greatly appreciated!
