Hello all. First off, I hate that my first post is a cry for help and not a response containing advice or answers. But, it is what it is.
I am using a iPhone 4 (GSM) that is jailbroken using Redsn0w running untethered iOS 5.0.1. I recently contacted AT&T and they agreed to "factory" unlock my iPhone since it was purchased under contract more than two years ago. In order to complete this process, a restore of my phone was necessary. This is where the problem began.
(just a fair warning: I have been jailbreaking my iPhones for a couple of years, so I can usually work myself out of a pinch...not this time)
When I attempted to do a restore of my iPhone 4, iTunes told me that the iPhone could not be restored because the firmware was corrupt. So, I re-downloaded the firmware several times. I have restarted my computer several times (I am running the most updated versions of Mac OS X Lion and iTunes). I attempted a restore from recovery mode and DFU mode (including pwned DFU mode from Redsn0w). I have tried restoring using saved SHSH blobs from TinyUmbrella (just a restore to 5.0.1). None of this has worked. I'm beginning to think it's my computer, but I'm not sure. I couldn't find many forums or articles on this and as far as I know the Apple Forums are silent on this issue (as regards to the iPhone...I found an iPod article that's similar but that fix didn't work either).
I'm open to any suggestions...any at all. Thanks.
