    I have an iphone 4 that ive had since june and never updated past 4.0.1.

    I tried to do a reset on the phone and it just got stuck in a boot loop.

    I have it in DFU mode now and i have the 4.0.1 ipsw file, but i cant restore it through the latest version of itunes or itunes 9.1.

    How can I do this?

    without SHSH blobs save, you can't restore to 4.0.1. Apple is currently signing 4.3.2 and you can only restore to this firmware only if you don't have SHSH blob save.

    At the iPhone hacks section.
    If you do an erase all on a JB iphone you'd be stuck having to restore.
    Did you have any shsh blobs saved and why do you want to stay at 4.0.1 and not the latest 4.3.2? Are you unlocked?

    I have similar question.
    Have an iphone 4 at 4.0.0(original) ,never touched it, (No activation, no jailbreak, no unlock), don't ask me why..?

    Now I want to use this phone outside US. if I try to install new iOS, system is downloading only 4.3.2.

    What are my options to unlock..?

    I also did this.
    One of the dumbest thing ever.
    It was on 4.01 and sold it to friend who wanted it clean.
    I did the all reset on the phone and it got stuck.
    So am I screwed ?? Only way to get the phone is to restore it to the latest firmware ??
    Anyway other options I have ???
