I had to reset my gadget (pressing power and home buttons for x seconds) because iFile completely froze it. After the reboot, no tweaks are around (the new toggles in Control Center, Activator gestures... nothing). I know in iOS 5 and 6 there was some "safe mode", but no indication of such thing is evident here. When I tapped the Activator icon, a dialog box said Mobile Substrate is not running, and mentioned safe mode. I tried power off/on, another reboot, nothing changed. Also, the tweaks section in Settings is missing. I can run iFile. Diagnostics & Usage has a new "panic.plist" entry around the time of the riginal" reboot. Any idea how to fix this?
