Is it possible to restore a no more signed iOS version to an iPhone? This for sure will not run over iTunes.

Please help!

To my knowledge this is not possible. In order to be able to install an ipsw firmware on a device it needs to be signed by an apple activation server. This server only signs the latest version.

Thank you SamBrown

We share your view. A recent article promotes of being able to downgrade but unsure this works with any non-signed iOS version
