As an outcome of my latest research in terms of iPhone 4S, I found out a pretty interesting thing. If you simply remove the Setup.app form the IPSW, even if you find a correct payload to send out the CFW it will get stuck on Apple logo. iPhone 4S is the only device behaving this way, therefore the process of correctly creation of a CFW is slightly different than on iPhone 5 and all the rest, even if it DOES use most of the techniques from that.
Please pay attention to the video as I explain some interesting things you may want to know.
I think by the launch of iPhone 7, Apple will finally drop iPhone 4S, and maybe even 5 as they are kinda old now…
It is just a supposition, but if they do, we’ll be able to create a payload without risking to have it patched by Apple with new iOS version, at least for a longer period.
