    I was downgrading an iPhone 6 from iOS 12 down to iOS 11.4.1

    I have reset the iPhone completely and down to a minimum.

    I keep getting the error message:

    “The iPhone could not be restored. Declined to authorise this image on this device for this user.”

    What is the next step?

    Thanks for your help.

    Does anyone know if iOS 11.4.1 resolves the battery life issues with iOS 11.4?

    iOS 11.4 is widely reported to cause huge battery drain and battery problems, people say it drains the battery very quickly.

    Has anyone noticed iOS 11.4.1 improve battery life?

    Share with us if you have knowledge of this topic.

    This might look like a boring software update but it has a potentially important security patch which should not be overlooked by security minded people. If you like privacy and security, you may want to install that update.

    Most notable is that iOS 11.4.1 includes an optional USB accessory block after 1 hour.

    Such a USB accessory block after an hour attempts to lock the USB port on the device.

    In other words, iOS 11.4.1 may help to prevent unauthorized access from hackers, attackers, and other entities who are attempting to hack into a passcode using something like a “Graykey” password cracking device. That “GrayKey” product which is apparently widely owned and used by various agencies around the world for various reasons, and is surely in use by other groups too, is discussed here:

    So this makes iOS 11.4.1 an important update for security reasons, though it remains to be seen how effective it is at blocking those type of professional attacks aimed at breaking into an iPhone or iPad. It’s always a cat and mouse game between security researchers, the hackers, and patches from the software.

    • Pointdexter says:

      Good point about security update, but some security researchers basically suggest this new ‘feature’ for USB connections is basically illusion and a security theater with no real protection. I do not know enough about this technology to make an assessment, so I observe what others “in-the-know” say.

      The suggestion is the only real protection remains very long and very complex passcodes that take a very long time to brute-force or guess. I had a colleague recently recommend 25+ character passwords that are very complex… that can be hard to remember and type out.

      A passcode requires guessing it, or knowing it.

      But theoretically, Face ID can be used by anyone holding a phone to your face.

      And theoretically, Touch ID can be used by anyone holding your thumb to the phone.

      Does anyone have true security and data privacy in mind?

      I wonder about features like “Hey Siri” which listens to you constantly as it apparently awaits a voice command, which is done by always listening for that voice command, but it must hear other words too all the time that it is active, so what does Apple do with that other voice data that it hears? Does anyone know? How is it housed and where is it stored and processed? Siri requires an internet connection, so do we assume it is uploaded somewhere?
