Jailbroken lockscreen crash I have the iPod touch 4th generation running jailbroken iOS 6.1.6.

The iPod is working fine except for when I lock it. When I try to wake it back up again, it doesn't come on. If I leave it for like a minute after trying to turn it on, it restarts the whole iPod for some reason.

Any ideas?
Boot into Safe Mode by holding the volume up button on boot. If the problem doesn't occur in Safe Mode, it's a substrate tweak causing the problem. Still in Safe Mode, go to Cydia and uninstall any lock screen related tweaks until the problem is fixed.
