I recently jailbroke my iPhone 4S and installed several tweaks. After restarting the phone, Cydia and the apps associated with those tweaks immediately crash when I try to open them. Re-running the jailbreak process normally fixes the problem, but today that no longer worked. Could this be caused by incorrect file or folder permissions, and how can I repair the jailbreak without losing everything?

This is often caused by a jailbreak file or folder having incorrect permissions, especially after installing a problematic tweak. If the jailbreak is semi-tethered or tethered, make sure you boot the phone through the jailbreak tool after every restart; otherwise Cydia and jailbreak-dependent apps may crash. If that does not help, remove the most recently installed tweak from the jailbreak tool or restore and rejailbreak the device rather than changing permissions blindly.

Thanks. Do you know the specific steps or tool I should use to repair the permissions or boot the phone correctly?
