So I tried to install a cydia app called "lockdown" on my phone. After installing it, opening any app or program, whether it be messages, notes, cydia, or the lockdown app itself, causes my phone to crash the springboard, and restart in safe mode. I can only use my phone from the safe mode. Is there any way I can fix this? I tried using the iPhone Explorer tool for my mac and deleting the lockdown app manually from my phone since I can't uninstall via cydia (cydia won't even open in safemode), but it has not solved the issue.
