Specs: iPhone 4S 7.1.2 Pangu Jailbreak Context: I attempted to fake my iOS version by changing it in iFile. Cydia no longer installs anything successfully. iFile is gone from the home screens. Apple App store also does not download anything or even show any content whatsoever. I tried some Terminal commands to reinstall Cydia, and it appears to have removed it, but without the reinstall succeeding. Now, when I open Cydia, it attempts to open but immediately it blanks and goes back to the home screen. Any ideas what to do? or is this the end for ol' iPhone 4S?
