After installing a tweak on Cydia (on iOS 7, iPod Touch 5th gen), after restarting the device, it would be stuck on rebooting constantly on the Apple logo or being stuck on the loading circle. After a HUGE pain, I managed to enter into safe mode, but it restarted after I opened Cydia. After restarting into safe mode multiple times, it would restart every few seconds. I'm unable to do anything, since it would not let me do a single thing before it crashes. Any help or advice? I would prefer not having to restore the device.
