To set the stage, my iPhone 12 pro 128 GB doesn't have enough space for the upgrade from iOS 16->17, so OTA updates are out of the question (for the moment). I backed up my iPhone to my mac running ventura and downloaded the ipsw and held down the option key, clicked "Restore iPhone", selected the downloaded ipsw and I am greeted with a panel that reads:
"A software update is required to restore your iPhone"
Clicking "Install" waiting for "Downloading 1 item" panel to timeout and I am presented with an error that reads:"
"Installation failed
Can't install the software because it is not currently available from the Software Update server"
I was under the impression that the ipsw was the operating system software and since it is iOS 17 is not in public beta, it wouldn't be available via the Software Update server anyway.
Has anyone else run into this?
