Apple stopped signing iOS 7 for the iPhone 5s years ago, making a standard downgrade through iTunes impossible. However, developers have created specialized command-line tools that bypass Apple's signing restrictions using hardware exploits.

If you plug an iPhone 5s into a computer today and try to install an iOS 7 IPSW file, iTunes will simply refuse to do it. Downgrade Iphone 5s To Ios 7
To bypass this, developers utilize a technique known as . However, on 64-bit devices, if the currently signed SEP is completely incompatible with the destination iOS version, an untethered restore will fail or break device functionality entirely.

Most checkm8-based custom ramdisk tools require macOS or a reliable Linux environment. Windows is highly unstable for these exploits. Under normal circumstances, this means that downgrading is
