    Unless I'm reading it wrong, that doesn't help you downgrade your phone, just fixes the recovery loop afterwords. iTunes won't downgrade, just gives the error when it tries to verify with apple.

    I've included my hosts file just in case theres a problem there. I can't think of what else could be going wrong.

    iOS 8.4 cannot be downgraded as no earlier iOS version is still being signed.

    Also, this thread is almost 4 years old and the original participants are no longer active.

    With that, this thread is now closed.
