I've recently bought a used iPhone 5s. The old phone I have is also a 5s but is on 10.2.1, while the new one is on the 11.4.1. I prefer the old ios version for cydia, but many online resources claim downgrading to unsigned versions (jailbreakable ones) are pretty much impossible.
So is there any possible way to downgrade or swap something from my old phone? Or am I better off waiting for the next jailbreak for now? Thanks

There's no way to downgrade.

No, it's not possible to swap components: they are all soldered onto the one circuit board. Add in Apple's Secure Enclave circuit, flash memory written by one processor, where the os is, cannot be read by a different processor.

You can try, but will wind up with two paperweights.

So the battery, screen, buttons, and camera for example, can just be swapped no problem?
