How do i fix my iPhone i was rebooting springboard in cydia now it's stuck on the loading circle?

If your iphone is stuck on the loading circle after rebooting SpringBoard through Cydia, try performing a hard reset by pressing and holding the Power and Home buttons simultaneously until the Apple logo appears. If that doesn't work, boot your device into safe mode by holding the Volume Up button while it starts up, which may help you troubleshoot any problematic tweaks. If issues persist, consider restoring your device via iTunes or Finder, but be aware this will erase all data.
