As John continued to use his iPhone 5s on iOS 7, he began to notice both the good and the bad. On the one hand:
: Most downgrade tools rely on exploits that only run reliably on macOS or specific Linux distributions. Windows is generally not supported.
Every time the phone reboots, you must put it back into DFU mode.
Open Cydia and add the CoolBooter repo ( pixeleyes.github.io/repo or official CoolBooter sources). Install the app. Downgrade Iphone 5s To Ios 7
Deep Firmware Update (DFU) mode is required to bypass the bootloader. Connect your iPhone 5s to your Mac.
The short answer is , but with major caveats. You cannot simply use iTunes to restore an iOS 7 firmware file (IPSW) because Apple stopped "signing" iOS 7 years ago.
Apple has updated its iCloud infrastructure. Logging into an iCloud account on iOS 7 may result in verification errors or cause sync issues with your newer Apple devices. As John continued to use his iPhone 5s
