I somehow corrupted my iPhone 5's user files and possibly other parts of the system, probably from respringing it 6 times in 5 seconds (long story). It no longer can use cellular data and has other odd problems. Anyway, I need to reinstall as much as possible onto it without restoring through iTunes because I cannot update past iOS 7.0.4 and lose my jailbreak. Plus I don't want the caps lock key to look like it's always on I tried Saurik's fake Apple update servers to try and restore it to 7.0.4, but that won't work. Also, the tutorial for that was from 2009. Cydia and some of its packages still work, so I have those at my disposal. Plus the iOS 7.0.4 IPSW files are there. How can I reinstall as much of the system as possible without updating to the latest iOS 7?
