My iphone went into safe mode after a springboard crash, I removed everything I had installed recently and still no joy. Then removed mobile subtstrate and hey presto Im out of safe mode. However, I have since re installed mobile substrate and back into safe mode, I have again uninstalled it and its fine again, now I cant download anything from cydia that runs mobile substrate as it goes back into safe mode ... any ideas ??? (i cannot restore as Im at 4.0)
I just had an issue with mobilesubstrate and I would recommend you reinstall it first.
I went into cydia and viewed my packages in the advanced mode (by tapping the "simple" button in the top right of the screen) and went to mobilesubstrate. I then selected "modify" and "reinstall." I rebooted my device and there you have it....fixed.
