    I recently downgraded my iPhone from 4.2.1 to 3.1.3 in order to unlock my phone for T-Mobile. During the unlocking process, my iPhone rebooted but is now stuck in a continuous reboot loop. No matter how many times I try to put it into DFU mode, it doesn't respond. I tried using iRecovery and rslite102 to kick it out of the loop using terminal, but that didn't work as well. I'm at my wits end, please help! Also, Last DFU 3g, TinyUmbrella, and RecBoot don't help either because all of the computers I try don't recognize my phone.

    Downgrading only the firmware won't even help you. Your baseband will still be the non-unlockable baseband that comes with 4.2.1.

    Unfortunately, I couldn't unlock it because my power button was broken. Now that I've fixed it, it's of no use because no matter what I do, my iPhone will not stop rebooting and it won't go into DFU mode.

    I've considered it, but I'm pretty sure it is. I just had it repaired and I haven't dropped it.

    Same trouble, Factory unlocked phone

    I have the same problem. My iPhone 3G is factory unlocked so I haven't used it with any other software than iTunes.
    Is there a way to get the phone out of this loop without restoring the phone as I don't have a recent backup?

    TinyUmbrella has an Exit Recovery function as well as a 'Fix', of which you could try either or both.

    Redsn0w also has several features that could help you, such as 'Enter Pwned DFU'

    Thank you.
    I was a bit reluctant to try these as they are Unix executable files and as I said, my phone is factory unlocked. I wasn't sure whether it might brick the phone or do harm to it in any other way as it has not been jailbroken.
    Long story short, nothing works. TinyUmbrella only gives the option of Exit Recovery, not Fix Recovery. Exit Recovery just restarted the phone into the loop again.
    Both of the Unix files entered a continuous loop in Terminal which I had to either escape out of or quit Terminal.
    I didn't try Redsn0w as I read it would jailbreak the phone. As I said above, it is factory unlocked. Restore now seems the only option?
    thanks.

    Redsn0w will only jailbreak the phone if you tell it to.
