Combing TONS of posts on macrumors regarding this subject and following the instructions/advice, I'm still am unable to accomplish the goal. Thought this thread could put it to bed once and for all and stand to help others looking for consolidated information. Particulars: Running iOS 3.1.2 BB 05.11.07 All blobs saved. (but I understand this is not needed) Jailbroken and unlocked via blackra1n. As I already saved the official iOS 3.1.2 from the iClarified link long ago, I downloaded the corresponding Pwnage Tool -- Version 3.1.4 to follow the advice here (but keeping consistent with my installed iOS 3.1.2): I went this route because numerous posts stated that restoring to a Custom Pwned firmware was necessary so as to not lose the 05.11.07 BB. HOWEVER, when doing this, I encountered the dreaded, "Wrong firmware bundle selected." This version of the Pwnage Tool also alerted me on startup that I wasn't running an iTunes 8.0 or later version (currently running iTunes 10.5). So I went back to the drawing board, re-downloading the official iOS 3.1.2 (using Firefox). That didn't work. In searching solutions to THIS issue, I tried creating a Custom .ispw by downloading iOS 3.1.3 with Pwnage Tool 3.1.5, but still got the same error. I have the strange suspicion I'm making this more difficult than it is. Many Thanks!
