Between 2018-2020, the iPhone 5s received an OTA update from iOS 7 → 8. Some users downgraded using delayed OTA profiles, but those profiles expired in 2021.

Apple only allows restores to versions they currently "sign" (usually just the latest iOS 12 build for the 5s).

In the world of technology, there is a distinct romanticism associated with the "golden era" of mobile operating systems. For many Apple enthusiasts, the iPhone 5s represents the pinnacle of that era. Released in 2013 alongside iOS 7, this pairing marked a seismic shift in Apple’s design language—the abandonment of skeuomorphism for the clean, flat, and colorful aesthetic of Jony Ive’s vision. The interface was vibrant, translucent, and famously powered by the brand-new A7 chip, the world's first 64-bit processor in a smartphone.
