So, I'm currently running 4.2.1, and I want to upgrade to the latest untethered jailbreak (which I think is 5.0.1, no?) Anyways, I followed this] guide, and was able to make the custom firmware successfully. I started the phone in DFU mode, and it had a black screen (like snowbreeze said it would). I went into itunes, shift+clicked on "Restore", and selected my custom firmware. It didn't get very far before it threw an error 3194 at me. So I did some googling, and it sounded like I needed to edit my hosts file, turn off some anti-virus, restart my computer, etc. So I tried all of these things with no success. Then, somehow my phone got out of DFU and started up normally, and I tried to restore with the custom firmware. It just said "Preparing to restore phone" forever, so I unplugged it. Now, on my iphone, it just shows a usb cable pointing to an itunes icon. I know I screwed it up, but now I don't know where to go. I am completely lost as to what I should do. My goal is to get a 5.0.1 untethered jailbreak while preserving my baseband. I thought I had done everything correctly up to this point, but obviously I jacked something up. Help?
