My iPad mini ios 7.0.4 jailbroken was working perfectly, I installed a tweak, not sure which one, and now whenever I open any third party apps, they crash immediately, I cant delete any apps from the iPad or download any new apps. When I try and open diagnostics and usage crash reports in apple settings either crashes or the report opens with just a blank white screen. I've tried removing all recent tweaks and the problem is still occurring. Cydia loads up fine and I'm able to install new and old tweaks without any problem. When i try and sync my iPad, iTunes remains on the sync screen, Copying Diagnostic Information, and does so indefinitely. I can't find a fix anywhere so all help needed!
