    A friend (not me :cool:) has accidentally updated his unlocked 1.0.2 to 1.1.2. He's tried using iTunes to downgrade to 1.1.1, but he says that even though he's alt-clicking and selecting the appropriate firmware, iTunes is refusing to allow him to downgrade.

    Is this a problem with his setup specifically, or a known issue?

    he is probably just getting an error at the end.
    He should use either iBrickr to complete the installation(right after he finished unpacking), or try iphuc32 (google it).

    I would highly recomend using iTunes version 7.4.2. That's the one I have.

    With itunes 7.5 and leopard, I am able to downgrade phones... I've done it like 20 times so far and then re-upgraded them to work on 1.1.2.

    You need the newest version of independence. and the right readline library.

    The independence is a beta and requires a little bit of work to get it going, but its all explained detailed in the readme.

    I think the iPhone needs to be in DFU mode for downgrading.
